The Ultimate Guide: How to Choose the Best Off-Grid Solar System For Your Home

There has been a huge rise in the popularity of off-grid solar panel systems recently mainly because of an incredible leap in home battery storage technology. However, once you start searching for the right off-grid solar panel for your home, you realise that there are many factors you need to take into account and that the general public has little understanding of the various solar/battery storage capabilities and limitations.

Although experienced off-grid solar panel installers may give you useful information and advice, you still need to do in-depth research to find out which off-grid solar panel system meets your requirements the best.

To help you find what you need, we did thorough research into off-grid solar systems. Today, we are going to show you how you can find what you are looking for by answering some of the most common questions and guiding you through the essential steps you need to take.

So, let’s dive right in.

1. Do an In-depth Research of How Off-grid Solar Panels Function

An off-grid system requires battery storage because it is not connected to the electricity grid. One of the most important things when it comes to installing an off-grid solar system is to pay close attention to its design because it will determine how much power it will generate throughout the year as well as the battery capacity.

These solar panels are more needed in more remote areas which are far from the electricity grid. In addition, off-grid solar battery systems market is growing rapidly even in urban areas.

In its core, off-grid solar system works by generating electricity from solar panels and using it to charge a solar battery via a charger controller. The inverter then converts that electricity and it powers the home or home appliances. In this way, you can run home with solar energy even during times when there is less sun exposure.

Every off-grid solar system requires the following components:

  • The battery bank – since you don’t have access to public electricity grid when using an off-grid solar system, you will need a battery bank. Once solar power is used by a variety of appliances, any excess power will be sent to your battery bank. In other words, when your solar system stops working, it will start drawing power from the batteries.
  • Backup Generator – When the weather is cloudy and there is not much sun power you could use to charge your batteries, you will need a backup power source such as gen-set or a backup generator.
  • Solar battery – a solar battery is an essential component because it provides the home with energy even when the sun goes down.
  • Solar Inverter – sometimes referred to as solar converter or PV inverter, solar inverter is primarily used to convert the direct current (DC) collected by solar panel array into alternating current for running most of household appliances, and electronics. When it comes to using an off-grid solar system, a stand-alone inverter is the right choice.
  • Solar Charge Controller – In order to save the battery, you need to have a solar battery charger. Also, this charger regulates the voltage and the current that the solar battery receives which prevents the battery damage.
  • Solar panels – naturally, this off-grid structure would not make much sense without solar panels. The size and production capabilities of solar panels will largely depend on the amount of sunlight in the area where you plan to install off-grid solar panels, energy consumption needs and finally, the usable space of the roof.
  • Battery Monitor – Battery monitor provides you with essential information regarding your battery bank but not all off-grid solar panels have one. A good-quality battery monitor is rather inexpensive and can provide you with critical information such as charge status of your battery bank, maintenance and troubleshooting information, etc.

off grid solar installation

Here are some other things you will need when installing off-grid solar panels or for its maintenance:

  • Remote temperature sensor
  • DC breakers
  • PV combiner box
  • Battery cables
  • AC breaker panel
  • Solar Panel Cables (MC3 and MC4 cables)
  • Gadgets and other small electrical items you may want

Typical off-grid solar systems are used in remote areas which are not connected to the local utility grid or in the areas where grid power is not consistent.

A few examples of these places include the following:

  • Outbuildings
  • Signs
  • Bunkers
  • Developing countries
  • Plain communities
  • Off-grid homes or lodges
  • Hunting cabins
  • Rural area power needs such as water pumping
  • Many more

Advantages of off-grid solar systems:

Choosing off-grid solar systems for your home has a number of benefits and definitely stands out from the rest of solar panels especially when the power is out. One of the biggest and most important advantages of these solar systems is that they convert light from the sun into a complete and usable energy for houses which provides you with a clean supply of energy or your home. Other benefits include:

  • The off-grid solar system design is suitable for energy storage which can later be used as a backup power.
  • This system is highly cost-efficient
  • Like wind turbines and geothermal power sources, these systems can minimise carbon footprint. In other words, they are environmentally friendly
  • The stored energy is ready for potential disasters, so you will always have that added protection
  • By choosing these solar panels you will be actually saving money in the long-run as you will have to pay low rates on a month-to-month basis
  • It’s an easy alternative for rural areas because you won’t have to pay that extra money to connect to anything. You will be able to control your own power and you’ll be able to live almost anywhere you like
  • Off-grid solar panel systems provide a much easier installation because the light can be located where it is required. While with traditional grids where you have to use the existing poles and infrastructure to put the power where you need it, you can install off-grid solar panels almost anywhere you want.

2. Fully Understand Your Own Power Use Habits

To make the best of your off-grid solar system you need to consider all the adjustments you will need to make prior to using an off-grid solar panel. You need to determine electricity consumption, especially during dark cold winter days and nights when power production is minimal and the energy consumption is at the highest level.

By using off-grid solar panels, you stop being dependent on the electrical utility, because this system provides all of your power. That’s why these systems are generally larger than grid-ties. On top of that, a system must have a large wind generator or an array of solar panels as well as a greater battery storage capacity than in the applications where grid power is available.

3. Size an Off-Grid Solar System

Off-grid solar panel systems are used mainly to power the industrial applications such as lighting, sensors, environmental monitors, security cameras, water pumps, traffic signals and many others that require reliable power in remote areas.

Before starting this journey, you need to carefully size a system based on a given location and energy requirements. We’ll guide you through a few essential steps you need to take to size your system.

  1. Determine energy requirements

The first thing you need to do is find out how much energy the equipment uses on a daily basis and this is measured in watt hours and kilowatt hours. To find out this information, you need to check the manual, discover how much power it consumes and then multiply it by the number of operating hours per day. The inverter is also very important component as it produces AC power. Remember to account for inverter-s self-consumption and efficiency losses. Efficiency losses usually range from 5% to 15% depending on the type of the inverter which is another thing that should be taken into account when sizing the batteries.

2. Evaluate site location

In order to estimate the available energy you need to carefully determine where the system will be installed. You can use a ‘sun hours map’ to estimate available PV resources. Be mindful that you should size the system based on the month which has the highest power consumption and the lowest solar resource, typically December or January. The easiest way to find the map is to visit the website of the National Renewable Energy Laboratory and determine available solar energy based on the location. For example, most countries in US have fairly low solar insolation in January. Also keep in mind that solar panels should be installed in full sun. Since shading can have an adverse effect on solar panels in general, make sure you inspect the site to see if there is shade somewhere and also keep in mind that the sun’s angle will change throughout the day.

3. Calculate battery bank size

This information should allow us to calculate and size the battery bank.Then we can determine how much solar power is required to keep it charged. First you need to account for inefficiency of the inverter. Then, you need to consider the effects of the temperature on the battery’s capacity to deliver energy. Also, account for the efficiency loss when charging and discharging batteries. In most cases, the battery bak size will increase due to factors including temperature and a number of days of required autonomy. Also, when sizing the battery always consider the discharge depth, that is how much capacity is discharged from the battery. In other words, sizing a lead acid battery for a maximum 50% depth of discharge will extend the battery’s life. On the other hand, lithium batteries are not equally affected by deep discharges and do not drastically affect the battery life. In order to make the entire system more reliable, you need to increase the battery size, especially in the areas prone to extended overcast weather.

4. Calculate how many solar panels you need

Now it’s time to size the charging system. Although, normally, most people would use solar panels, sometimes using a combination of wind and solar might make more sense, especially in the areas with good wind resources. The charging system must produce enough energy so that it can fully replace the energy drawn out of the batteries. When calculating, you need to take into account real-world losses caused mainly by inefficiencies, aging, module soiling and voltage drop.

Another thing that should be taken into consideration is the battery capacity. Before choosing your solar panel, refer to the battery specs as well as user manual to see and confirm the minimum and maximum charging guidelines. If you fail to follow these guidelines, you risk premature battery failure which is the last thing you want because buying a solar panel system is a big investment.

Apart from the things we have discussed here, there are many other factors that can influence the system size. If you want to reduce system size, there are also other alternatives such as incorporating a backup gas generator or even a wind generator.

Finally, if you are planning to install the system in a remote area and if the equipment is critical, you should consider oversizing it, because, eventually, the cost of maintenance will exceed the price of a few extra solar panels. On the other hand, if you are planning to power certain apps, you may want to start small and then expand depending on how it performs. It’s all up to you to decide. Generally, system size will eventually be determined by your energy consumption, the site location and also the expectations for performance based on days of autonomy.

Correctly sizing your power needs is probably the most important step when choosing your off-grid solar panel. Why? Because it will determine how much money and time you will have to invest into its installation. In other words, the number of your solar panels and the size of your battery will largely depend on your location, power usage, how many people are living in your home and the efficiency of your electrical appliances. One of the ways to do this is to arrange for a consultation with a professional solar panel installer as they will provide you with a comprehensive analysis and all the necessary information you need. For example, for an average home or four or five people, a five-kilowatt solar system is usually recommended. However, to be sure that you are making the right decision it’s always better to consult a professional and let them accurately size your solar system.

4. Understand the Material

Another important criteria when making this decision is the type of solar panels. All solar panels have different types and knowing them will help you make your decision and not get confused when supplier mentions them. Here are a few essential categories of off-grid solar panels.

  1. Monocrystalline – These solar panels can absorb a large amount of solar energy which automatically gives them a higher power output. They are particularly good homes which have roofs with less space and them most certainly eliminate the space wastage.

monocrystalline solar panel

  1. Polycrystalline or Multicrystalline – these solar panels are made of purified and molded crystal bars. When compared to monocrystalline, these solar panels are unquestionably less expensive and more popular among the users.

polycrystalline solar panels

  1. Amorphous – these solar panels are made of thin film silicon cells which respond well to slightly diffused light.

Each of these solar panels have their advantages. However, the location where solar panel will be installed should also be considered. For example, Monocrystalline and Amorphous solar panels are more suitable for areas where there is strong uninterrupted sunlight most of the year.

5. Choose a Battery

Choosing the battery for your off-grid solar system is a critical point in your decision-making process. One of the biggest benefits of using off-grid solar system is the independence you have from utility companies and the ability to use your own electricity. However, this won’t be possible without appropriate battery for your application. Here are some important things you need to know when choosing your battery.

First and the most important thing you need to keep in mind is that renewable energy systems like off-grid solar panel systems require deep-cycle batteries – batteries that discharge very low over a longer period of time.

So, what makes solar batteries different from other batteries on the market? There are two types of renewable energy batteries today on the market:

  • Flooded lead-acid batteries – these batteries are mostly chosen by the owners of off-grid solar panels because their price is pretty affordable. On top of that, they tend to last longer because they are regularly serviced and cleaned which prolongs their life-span considerably.
  • Sealed valve regulated acid (VRLA) batteries – unlike the flooded batteries, these batteries are sealed and made of a lead composition. What makes them so special is the fact they do not need physical maintenance. If you have a good battery charger, you will not have to worry about their inner plates and fluids as the charger will significantly extend the battery’s life.

solar batteries

However, before choosing between these two types of batteries, think about where they will be located as well as whether you will have enough time and will to regularly add liquids and check battery levels, which flooded batteries require.

Once you have decided which battery to choose, you need to think about how to size your battery bank. To do this you need to have a clear understanding of how batteries are rated as well as their life-span. Batteries are rated in amp-hours.

For example, a battery rated at 100 amp-hours means that it can put out 1 amp of electricity for 100 hours. Its lifespan largely depends on the depth-of-discharge (how low the battery is drained) as well as its cycle-life (one cycle-life equals to a fully charged battery draining down below 30%).

Be mindful that it is always better not to drain the battery below 25% because it will have a positive impact on its life-span. In other words, don’t use over 25% of their total potential because, in that way, your battery will last longer.

Another thing to keep in mind is that you should never mix and match old and new batteries, nor you should combine the batteries of different capacity and type. Also, make sure you don’t add batteries that are older than six months to your battery bank.

Choosing an off-grid solar panel is a good investment, but it does not make sense if you do not do a thorough research of all the necessary components. When choosing your battery, you should never sacrifice quality for a cheaper product.

Instead, buy batteries that will last many years and that will pay off. Any reputable company you decide to buy your batteries from will have all the documents and specifications that will help you size your battery bank.

6. Choose Your Off-grid Solar Inverter Core

solar inverter core

An off-grid solar inverter takes DC power from your solar panels and converts it into AC power which is then used by your home applications like fridge, lights, TV and other appliances. An off-grid inverter requires a battery bank to function. It is more complex because it has additional components such as the charge controller and battery monitor.

When picking the off-grid inverter that will perfectly suit your needs, you need to:

  • Think about size – Think about how much power you need by adding up wattage of all of your lights and appliances to calculate the number of watts. However, dont forget to calculate the voltage – while most appliances run on 120Vac, some appliances such as well pumps require 240Vac.
  • Check the specifics – each inverter has its own specific you need to chack prior to biying your inverter such as:
  1. Efficiency – this refers to how much power from the batteries your inverter delivers to your home when operating in perfect conditions. An efficiency that is considered good is around 94% to 96%.
  2. Self-consumption – this refers to the energy your inverter will use up by just sitting there without being used.
  3. Battery charge output – Since most off-grid inverters will have their own battery charger whose role is to power batteries during cold winter months, you should look for battery chargers that have a rating in the range of 50-100 amps DC.
  4. Warranty – to be certain that your off grid inverter will have a longer life-span you need to check the inverters warranty. While most installers offer warranty that start at one year and typically range from 3 to 5 years, there are some companies that offer a 10 year warranty extension option.

Besides its primal function to deliver electricity to a solar panel, inverters have many other functions such as:

-providing options for extra tools and services including system design engineering, data monitoring advanced utility controls, applications as well as a host of other different services. All of this has one aim – to ensure that an inverter can operate at optimal performance level. In order to get maximum performance of your inverter you need to keep them running as efficiently and reliably as possible. There are a few factors you need to consider when choosing your off-grid solar inverter:

  • They need to be highly reliable
  • They need to offer ongoing data monitoring
  • They need to offer preventive maintenance
  • They need to offer operation and maintenance services
  • They need to have a proven and bankable warranty

The good thing about off-grid solar inverters is that they are already multi-taskers, This means that they are combination of inverters and chargers and that they have bi-directional energy capabilities to convert DC to AC and vice versa. This allows off-grid inverters to simultaneously manage PV or other energy resources and maintain battery storage. The difference between off-grid and on-grid solar systems made it easy to categorise solar inverters into two separate classes with little or no overlap between them.

Here are some of the most common off-grid solar inverter sizes :

  • 1kW – these inverters are ideal for small, part-time cabins as well as for smaller appliances like phone, and lights.
  • 1-2kW – these inverters also ideal for smaller cabins, more specifically for appliances like lights, phone, TV and fridge
  • 2-4kW – Ideal for small cabins and homes
  • 4-8kW – besides homes, these solar inverters are ideal for powering most residential well pumps
  • 8-16kW – These inverts are ideal for homes, farms, ranches and smaller commercial buildings
  • 16kW – these solar inverters are ideal for commercial buildings and large homes

Multi-talented hybrid inverters will start gaining more popularity and eventually become more standard at the center of energy systems. Features previously considered the exclusive territory of off-grid inverters will become increasingly common in grid-tied systems.

7. Choose Your Off-Grid Solar Charge Controller

off grid solar system

In order to choose the best off-grid charge controller, you need to understand well how a controller works. Basically, an off-grid charge controller takes the energy collected by your solar panels and send it to a battery bank where this energy is stored. In other words, charge controllers control the charge. Your controller will both ensure that your battery receives the most energy from the panels and that they never become overcharged.

If you do not know what size of charge controller you need, you can either use one of the calculators you can find online or simply consult online or telephone support to help you make the best decision when it comes to the size and voltage of your controller.

There are three types of controllers: PWM, MPPT and Chunt Charge Controllers

PWM (pulse width modulators) – a basic type of a controller that can be found easily on the market and at very cheap prices. These are standard type of controllers. Once the battery is full, the controller utilises the “trickle effect” by allowing only small amounts of current to flow into batteries. If there is a constant supply of energy, then PWM controllers can indefinitely maintain the battery’s charge full. In order to use this type of a controller, you need to ensure that your solar panel and your battery has the same voltage. Since in most homes solar panels and the battery usually have different voltages, these controllers are ideal for smaller solar systems using lower voltages.

MPPT (maximum power point tracking) controller – a much more advanced type of a controller that offers a wide array of functions and it is much more common on the market. It will prolong your battery life and take the maximum amount of energy and deliver it to your battery bank. On top of this, this type of controllers allow you to pair solar panels and batteries with different voltages and they are highly sophisticated. In other words, they regulate the current flowing into the batteries by allowing much higher voltages into the wires from solar panels. It also allows solar panels to operate optimally at all times because it prevents reverse flow of energy from the batteries to the panels when there is no more solar energy supply. These types of controllers are especially efficient when you want to use higher voltage panels to charge lower voltage batteries.

Shunt Charge Controllers

This type of a controller has simple on off controls and are extremely easy to work with. They allow the maximum amount of current to flow in through a blocking diode. In this way, it automatically switches on once the threshold voltage is reached. This prevents the battery from getting further charged. The controller will regulate the array of current flowing in until the full charge. Besides being extremely practical and easy to use, they are also very affordable and reliable. In addition, they are an excellent choice for wireless applications where you want to keep electrical noise at the minimum.

When choosing your controller, there are a few steps you need to take to make sure you have chosen the right one. You can either Use the manufacturer’s sizing tools that are usually offered on their site, or simply call them.

Although there are many models on today’s market, there are a few parameters that you would need to consider if you want to find a controller that fits your needs. Check out the features that are available on most charge controllers (naturally, the best controllers will have most of these features):

-solar, wind and hydro MPPT modes

-Online status monitoring

-12-72 volt battery charge

-built in GFP and arc fault

-Hyper VOC extend VOC limits

-150, 200, 250, 600 V

-manual and auto EQ

-Low-voltage disconnect (LVD) – disconnecting the loads plugged in case of low battery state of charge and reconnecting the loads when the battery is charged again.

-Reverse current protection – this prevents batteries from draining at night when the battery cannot be charged by the solar panels.

-Control display panel – it shows state of battery charge and a battery bank voltage, as well as the current coming from the solar array.

Now, you are probably wondering whether you always need a charge controller in your off-grid solar systems or not.

One thing to keep in mind is that without a solid solar charge controller, your battery will be exposed to frequent overcharges and over discharges which would dramatically reduce the lifespan of the battery. This is definitely not something you are aiming for. That is why you need a high-quality charge controller to give you a piece of mind. However, if you have a solar panel of very low power, below 10 wp, and a battery of 100 amp-hours of capacity, then you do not need a solar charge controller.

Also, there are a few factors you need to keep in mind to make your decision-making process as easy as possible:

  1. Ease of installation

Installation process is one of the essential factors and should therefore be given some thought. Naturally, if you have all the necessary information and details to install it yourself and if the controller is not too complex, there is no need for you to hire a professional. However, if it turns out that your controller is complex by nature that you are at loose ends what to do, it’s always a better option to consult somebody and hire an expert who will provide you with all the insights and make the installation process run smoothly.

Here are some of the most common rules you need to obey during charge controller installation:

  • Certain appliances including refrigerators must be directly connected to the battery
  • The inverter should be directly connected to the charge controller “DC load” terminal
  • Most controllers have three terminal connections – for the battery, for the array and for the DC loads. In its core, the charge controller disconnects the battery to prevent it from overcharging and disconnects the DC loads connected to the controller “DC load”terminal to prevent the battery from overcharging
  • Every device you connect directly to the battery instead of the “DC load” terminal of the charge controller renders the battery’s capacity to stop over discharging useless.
  • There is no need for any fuses than the one embedded in a charge controller when you have a small DC system with a charge controller. If you are dealing with larger DC systems, then you need to provide a fuse on the positive terminal of the battery.

2. Safety

Safety is definitely one of the most important factors when it comes to choosing your controller. None of it makes sense, if you put your health and safety in danger. If you are not sure how to deal with technical data and avoid accidents, seek for help.

3. Storage Temperature

Temperature is another factor that you need to keep in mind. Temperature influences the state of and the efficiency of charge controllers and should therefore be a top priority. While PWM charge controllers perform best in warm environments, MPPT work best in cold environments as well as when the battery is low.

4. Budget

If you want to have a quality product, you need to invest in it. The same applies to off-grid solar charger controllers.Basically, the more features the controller has, the more costly it will get.

5. Energy needs

This is probably the most important factor. To get an insight wht king of controller you really need, you have to calculate the amount of energy you will need for your entire home. For example, if you are planning to power up lighting, heating and cooking purposes, then MPPT charge controller is an ideal solution for you. If, on the other hand, you need a solar power for a smaller PV system such as lighting a sngle or a few rooms, then a PWM controller is just what you are looking for.

8. Choose the Right Solar Mounting System

best off grid solar system

Another important component of every off-grid solar system is definitely solar mounting system. A good solar mounting system will have two important features:

  • It will collect as much sunlight as possible provided it faces your solar panels from the right angle and direction
  • Reduce or eliminate the amount of shade that prevents the Sun from hitting your solar panels

Naturally, when choosing your solar mounting system, you need to think about esthetics as well. Do you want panels to visible or not?

Basically, there are three types of mounting systems you can choose from. Which one will you choose depends on your requirements and preferences. Those three types are:

  1. Roof Mount
  2. Ground Mount
  3. Pole Mount

Roof Mount – this mounting system is the most common system and maybe even the most popular on today’s market. However, before deciding which mounting system you will choose for your home, you need to keep an eye on the condition of your roof.

Since the solar system you are planning to install is designed to last for 30 years, your roof must be in a good condition so it can withstand different conditions. The roof is definitely the most suitable and practical place to install a solar panel because in that way solar panels are exposed to sunlight.

Therefore, make sure your roof is suitable for solar panel installation. You surely don’t want to change your solar panel in just 5 years time.

If you are not sure about the current state of your roof, you can always consult solar panel installers. They will surely have the answers to most of your questions and provide you with all the necessary details. In case it turns out that your roof needs to be repaired don’t hesitate to invest in it.

When choosing you off-grid mounting system, always keep in mind that your solar panels need to collect as much sun energy as possible and convert it into electricity.

Another thing to keep in mind when deciding which mounting system is the best option for your home is the time of year and geographical location. For example, during the cold winter months the Sun is very low on the horizon, therefore the optimal angle to capture the sunlight will be higher than in summer months, especially in May and July.

If you want to be sure that your solar panels capture the most sunlight, you can always opt for solar tracking (this involves installing your solar panel on a motorised mounting system that follows the sun throughout the day. In case you do not have ideal roof, you can consider buying a few more solar panels to cover your electrical use and make the best of your roof space.

One of the crucial factors you need to consider is shading. If you install your solar mounting system and only one electrical cable casts shadow on it, you won’t take full advantage of your solar system capacity. Shade can greatly decrease the overall production of your solar array.

On top of that, it’s very important not to consider only current shading but also shading that may occur in the future. In other words, besides shadows cast by walls, poles, chimneys, etc, ,think about trees that may grow in the near future and the shadow they will cast.

Also, if you are living in an area where there is a lot of dust, you need to have easy access to your solar panels, so you can clean or hose off the dust and keep your solar panels well-maintained. Solar panels are specifically designed to be durable, so you don’t have to worry about damaging them ir scratching them.

One more thing you need to think about are weather conditions. Consider the accessibility of your panels when it is raining or snowing and you want to remove snow from them. In case your roof is not the best option for installing your mounting system, there are other options.

Pole Mount

Pole Mount System will use one or more poles to lift your solar systems off the ground. In this way, you will have more space on the ground and you will be able to achieve the best possible orientation and angle for your solar panel. This mounting system is usually the best possible solution for people who have limited space on the roof and not so ideal shading and pitches.

Ground Mount

If you are looking for an easy-to-use mounting solar system that you can install effortlessly, then ground mount is the perfect solution for you. If you have enough space to build an “A” frame style ground mount system, you can place your panels in both the optimal southern orientation as well as the optimal pitch. Alslo, you can easily adjust this system to get the best angle for each of the seasons in your region. If you have limited space on your roof, and your project is relatively small, then this solution may be just what you need.

Choosing the right mounting solar system is another important step when trying to decide which off-grid solar panel to invest in. Whether you choose Pole Mount, Ground Mount or Roof Mount, be mindful that you need to consult and authorised installer about the installation process.

8. Check other people’s reasons behind investing in off-grid solar systems

One of the best ways to find out which off-grid solar systems is best for your home is to read the quotes or talk with people who have had experience with this kind of solar systems. They will provide you with all the information you need and clear any doubts. They may also advise you about the best brands and solar installers as well as give you useful suggestions regarding the solar panel maintenance and installation process.

To give you some insight, we did a bit of research and found out some of the reasons why people choose to invest in an off-grid solar panel.

  1. Off-grid solar panels save electricity costs

According to many people, investing in an off-grid solar system will help you save a lot of money in the long run

2. They are environmentally friendly

One of the ways to help the environment is to use the natural solar energy to power resources, and what better way to do that than by installing off-grid solar system in your home. As a matter of fact, one of the top reasons why people opt for this type of solar systems is because they are environmentally friendly.

3. Great back up/self-reliance

Most people prefer off-grid solar system because they give them their piece of mind. They no longer have to worry about whether the power will cut off or not. Once you know you have a back up, you no longer have to deal with unpleasant unexpected events.

9. Check the Off-Grid Solar Energy System Life-Span

One of the important things to keep in mind when choosing your solar panel system is also their life expectancy. Naturally, when we are choosing the solar system for our home, we pay close attention to its cost. However, when we invest in the solar system we also expect it to be durable and have a longer life-span. In other words, we expect to have our return on investment.

Essentially, the longer your photovoltaic system lasts the longer the your system will produce energy. While off-grid solar systems may cost a bit more than on-grid solar systems, they will unquestionably bring you benefits as you will need the battery backup systems and other components necessary to store your power.

Most manufacturers offer a standard 25-year warranty on their solar panels and guarantee that their energy output will remain at 80 percent of capacity or even greater for 25 years. Although this gives you a sense of security and prevent your from worrying about whether something will go wrong with your solar panel or not, you must think about the period after those 25 years.

While they may not stop working once 25 years go by, they will certainly generate less power over time. And, you can’t be sure how much.

However, if you choose to install an off-grid solar system and if you invest a lot of your time into caring about them, your system should continue to operate for many years to come or even decades beyond the warranty date.

However, when thinking about your system life-span you should also consider the durability of other components. For example, most inverters and battery banks have a 5-10 year warranty which is essential information when considering installing a solar power system.

One thing you need to keep in mind when going through this decision-making process is that photovoltaic panels are not designed to last forever. This in most cases is unavoidable because it is simply not possible to protect the system entirely from weather conditions as well as from the environment in general. However, experts predict that you can potentially extend the life of your solar panel system if you take care of it properly. Here are some things you can do to protect your off-grid solar panel system in the long run:

  • keep your trees trimmed regularly as it will decrease the physical impact of the environment and prevent your solar panels from damaging
  • periodically clean your solar panels by removing dirt or debris. Rainstorms can usually clean all the pollen, animal droppings and debris in general from your solar panels. However, in arid climates, there are fewer summer storms. If you are living in such an area, you can simply rinse dust off with a garden hose. Make sure that the water you are using is demineralised, as hard water can cause scaling and corrosion over time. On the other hand, if you live in the area where pollen and dust are a recurring issue, you may consider installing a roof-mounted sprinkler system and take the headache out of regular cleaning. Aslo, if you decide to install a sprinkler, make sure you consult an installer so that the sprinklers won’t negatively impact your solar panels or your roof. Generally, by cleaning your off-grid solar systems you will enable your system to run more efficiently
  • consult a qualified solar contractor and make sure you have your system inspected regularly and complete any necessary maintenance before a potential damage or a malfunction affects the system’s performance.
  • if you are living in the area with high chances of snowfall, regular snow removal from your solar panels might be difficult and challenging. In most cases, snow on your roofs will melt down and you wont need to clean it. However, if it is too cold for the snow to melt, you may have to use a broom or a snow rake to remove the snow. Again, consult your solar system installer and check your warranty or manual to ensure this won’t damage your solar panels.
  • in case of an ice-build up, you may need to consult a professional maintenance service recommended by your off-grid solar system installer in order to prevent any long-term issues. This is extremely important because ice may weaken your roof and cause corrosion on your rack or the panels themselves which entirely threatens the solar panel integrity. In most cases it is very difficult and challenging to deal with such situations on your own. That is why it is highly advisable to consult a professional.
  • clean the batteries – as water escapes through the cap, some may leave condensation on the top. This fluid can be slightly acidic and even electrically conductive. This means it can create a small path between battery posts and pull more load than necessary. The best way to avoid this is to clean the battery terminals. You can do this by mixing baking soda and distilled water and apply it using a special brush. Rinse the terminal with water and make sure that all connections are tight. Coat the metal components with a high temperature grease and make sure the baking soda doesn’t get inside the cells.
  • do not mix batteries – mixing new batteries with the old ones can have an adverse impact on the performance since the new ones usually degrade very quickly to the quality of the aged ones. By properly maintaining your battery bank, you can significantly improve the system ‘s efficiency and extend the lifespan of your off-grid solar system.
