Most Efficient Solar Panels for Home – Buyer’s GuideMost Efficient Solar Panels

As you know from the beginning that solar panels store sunlight and convert it in a form of energy source which we call electricity. The electricity is DC that will give your house a light-up that will make your life easier.

But if you are considering buying one you should keep these things in mind and check them thoroughly before progressing forward in your purchasing decision. 

Charge Controller

The charge controller is used for controlling the enormous charge that a solar panel absorbs from the sunlight. As the charge can be too much to handle there this device comes in and handle the charge.

It will reduce the charge and will only give that much charge that your house needs to manage all the electronic items in the house.

This can be the most important thing for you as if the charge controller is not there with the solar panel it can burn entirely your whole house appliances with a tiny bit of charge.

So make sure to check the charge as they can handle or control charge in these values 12V, 24V and 48V. You should check all these three values without buying a solar panel.


As you can see a charge controller, controls the charge and then progress the charge as it is needed and it will not provide you more or not less.

You should be thinking that the charge controller only provides a limited charge as the requirement so where all the other charges go if it’s not being used?

That a really good question and the answer is that the charge that is not used is stored in a battery so it can be used later as if you see the solar panel in charge by the sunlight so if the sunlight is gone at night what will give the house electricity.

This is where battery comes and it will give all the stored charge to keep your house light up in the night also.

So if you are buying a solar panel you should consider buying a battery for it so it can help the charge controller store the remaining charge in the battery. 


As you know all the electronic appliances work with alternative current (AC). if you make them work on direct current (DC) they will automatically explode or get burned from inside.

For that problem, you should buy an inverter that will help you convert DC into AC so your electronic devices such as microwave, refrigerator, and many others do not burn or explode.

It can easily switch the DC electricity to AC electricity to avoid such problems from happening.

Power Output and Efficiency

 The power of a solar panel does not mean that it will give only 100W supply to your house and you can only start those devices that are below 100W.

Power output can be described as if your device needs a power of 150W it will give the power with less efficiency or will use all the battery storage power to keep up with the electronic device and try to maintain it at its full strength.

The 100W nameplate is just a name that is given by the Standard Test Conditions (STC) that test all the panels or other appliances before launching them. 

Weight and Dimensions

The weight of a solar panel can be considered as a priority as well. A heavy solar panel can be troublesome for an installer to install as many people like to install the panel on the roof and can be very difficult if the panel is too heavy to lift or maintain on the roof.

That’s why many people suggest and consider to buy a lightweight solar panel so you can easily connect them on the grid as well as off the grid.

As for the dimensions that can be important too because a dimension too big can cover your whole roof or can be unbalanced as you have bought a large panel that is bigger than your roof.

So keep in mind do please check your roof dimensions first before buying a solar panel so it can easily fit on your roof without giving any trouble to you or the installer.

FAQ’s about Most Efficient Solar Panels for Home

Why Should You Care About Solar Panel Efficiency?

If you raise the efficiency it will directly affect the size and power output of the solar panel. Just imagine if you have a specific size and power output of a solar panel and if you just raise a little bit of the efficiency the power output will increase and will give you more power.

If you just put this thing in the practical world and raise the efficiency of a solar panel the size will remain the same but it will increase the power out which means the power output will increase from the actual power output the solar panel came with.

In other words, the power will consume less space than it usually does. On the other hand, if we decrease the efficiency of a solar panel the PV system will require more power as the solar panel will have the same size but have less power to operate it.

Therefore, if you select the right panel model that has an appropriate efficiency that your PV system needs will have a significant impact on the power output rating and you can easily increase or decrease and their will no problem causing for the PV system.
