Life on the open road is a joy, as we’re sure any RV-advocate would agree. But it can also be costly, or at least time-consuming, when one is forced to keep a close eye on the charge level of their RV’s battery, and make frequent stops to recharge it, in order to keep using their onboard appliances. But with so many products available with which we can harness the power of sunlight, it goes without saying that RV solar panel kits are great for RV trips.

Not only is a solar system environmentally friendly but also highly cost-effective. Though solar kits can be expensive, once they’re up and running, they require minimal maintenance and zero cash injections while continually producing electricity for free thus enabling you to enjoy the freedom of the road without the constraints of conventional battery-charging. Moreover, a good RV solar panel kit can optimize the unused space of your RV’s roof, in order to produce maximum amps, whilst occupying minimal space. Solar power is remarkably easy to install too, making it truly the best option for the eco-conscious traveler.

How Do Solar Panel Kits for RVs Work?

Kitting out your mobile home with renewable energy is a guaranteed way to save you money on gas, keep your on-board appliances working, and ensure that you’ll never again suffer the consequences of a dead battery. But just exactly how do they work? There’s no denying that solar panel arrays for your RV require an expensive initial investment, and as such, you don’t want to rush into it without first getting your head round the fundamentals of solar technology. Equipped with the right knowledge, you can make the best, most informed choice.

Let’s start with solar panels. Whilst they might look space age in construction, solar panels are fairly straightforward generators of electricity. A single panel is comprised of many individual photovoltaic cells, housed in a waterproof, weatherproof, UV-resistant and often lightweight casing. These cells are typically polycrystalline or monocrystalline silicon wafers, with electrical contacts (busbars) printed onto them. When exposed to sunlight, these cells react chemically and physically in what is known as the ‘photovoltaic effect’, converting the energy of that sunlight into consumable electricity.

Once solar panels have converted the sun’s energy, thus generating electricity in the form of DC volts, the electricity passes along wiring from the panels into whichever batteries and/or appliances you’ve connected your setup to. On board a motor home, you may choose to power a specific appliance (like a fridge-freezer or television) with your solar array, or you might be charging a battery, to store the generated electricity.

RV solar panels are typically mounted on the roof of the vehicle (unless small enough to be stored away for use only at rest stops), and can often be mounted on tilting brackets, ensuring that you can maximise their exposure to the sun no matter in what direction you’re driving. Since solar panels can only generate electricity during the daylight hours, many RV owners like to connect their solar kits to a battery which then feeds into their appliances. This allows you to store any surplus energy generated during the day, to keep your appliances running and charged overnight.

The final important aspect of solar RV kits to talk about is the charge controller, which is included in most good quality kits. The charge controller is a crucial element of any solar setup, since it not only allows you to track the energy production of your panels, but more importantly monitors and corrects the energy production, to ensure that the voltage and wattage of electricity produced is maximised for the battery or appliances receiving it. In other words, a charge controller means that you don’t have to worry about your solar panels overcharging batteries or shorting appliances on a really bright day, just like you don’t have to worry too much about it not producing enough energy on a dull day.

Pros and Cons of RV Solar Panel Kits

We’ve explained for you the detailed workings of your RV solar panel kit, but what are the base line pros and cons?

Pros:

  1. Green energy. The environment may not be your first consideration when looking to invest in solar panels, but it’s nonetheless one of the most important issues facing us today. With so much of the world being torn down and dug up to produce fossil fuels, and with the global temperature continuing to rise at an alarming rate, doing our bit for the planet has never been more important. Solar energy produces no dirty carbon emissions, and helps out a world in need.
  2. No fuel costs. Instead of having to power your on-board appliances with gas or expensive electricity, you can do so for free, forever, with an RV solar panel kit. Though installation and initial purchase can be expensive, solar arrays are hardy and long-lasting, and will pay for themselves several times over come the end of your road-tripping years.
  3. Space conscious. Whether mounted on your RV’s roof or folded and tucked away in an on-board compartment, RV solar panel kits are designed to make the absolute most out of very little space. We know that for mobile home owners, space is of a premium, and you’re not likely to want to give any of it up. With solar panels, you don’t have to.
  4. MPPT charge controller optimisation. If your chosen kit comes with an MPPT charge controller (MPPT standing for ‘maximum power point tracking’), then you don’t ever have to worry about whether you’re getting the most out of your kit; you’ll know you are, at all times.
  5. Ready to go! RV solar panel kits come with everything you need – the screws, brackets, fixings, wiring, panels, and controller – to install your solar array yourself and have it up and running straight away. No additional purchases required.

Cons:

  1. Expensive. Let’s talk about the elephant in the room. Solar panel kits are, though much more affordable than ever, rarely cheap, and when it comes to the size of kits needed to power mobile homes, they can be downright expensive. Still, with the cost cutting to fuel and electricity bills they bring you, and given how sensible an investment they are for the future, we maintain that the money’s worth it.
  2. Light dependent. As with all solar technology, the amount of electricity generated by RV solar panels varies depending on their exposure to sunlight. Whilst high-quality monocrystalline panels tend to generate power quite nicely even on dull days, some – like lower-quality polycrystalline panels – will struggle to generate any electricity when the weather’s overcast. Depending on where you plan to tour, solar kits may or may not provide you the electricity you require.

RV Solar Panel Kits Buyers Guide

What features should you be looking for when buying an RV solar kit?

Space

By their very nature, mobile homes have limited space. Typically, your roof is where you’re going to want to install your new solar panels, but this is not always possible, depending on what you already use your roof for, or how its shaped. Thus, one of the first things we’d recommend thinking about is how much space you have to spare for your new sustainable energy kit. If you’ve plenty, then you could certainly look at some of the really expansive, 400-800W kits. If you’ve some, but not much, then certainly those kits which offer 200W in one panel (essentially, more wattage for less space) are your best option. And if you’ve really no space to spare at all, then we’d recommend you look at the small, less powerful foldable panels.

Power

What wattage output do you need? It’s a simple question, but a crucial one to know the answer to before you start solar shopping. First thing’s first, determine which of your onboard motor home appliances you want (or need) to power via sunlight, and total up the daily amps it takes to power them. Now you can look at solar panel kits and determine the exact system you’ll require to keep those appliances constantly powered. For example, to power your RV’s air conditioner (which you might use for five hours a day, say), you’ll need at least 107Ah from your panels. Likewise, to keep your refrigerator running on solar, you might need four or five large panels charging constantly, and with a good-quality means of harnessing surplus energy for running the fridge overnight.

Monocrystalline or Polycrystalline?

The difference in solar cells matters a lot when you’re out on the road. Mono crystalline technology is designed to charge even in low-light conditions, and whilst you can get away with Poly crystalline during bright weather, you’ll still not be pulling as much power from the sunlight as you would be with Mono crystalline cell solar panels.

Safety

With a lot of wiring and power generation going on, there is always the potential for fire. Thankfully, this is not something you should be too worried about, as almost all (if not all) of the RV solar kits on the market manage their power output carefully and safely, via charge controllers, which allow you to monitor the power being fed into your batteries, and stop them from overheating. However, safety must always remain your primary priority, which means making sure the panels/wattage/voltage you have running through your charge controller is kept within its range of safe operation.

Final Verdict

Taking into consideration price, manufacturer-reliability and provided warranties, space, and energy efficiency, our final verdict is that the Renogy 100 Watt 12 Volt Monocrystalline Solar Panel is our top overall pick.

FAQs

Are solar panel kits easy to install on RV’s?

Ranging from zero-installation required, to kits which require a little more time and consideration, you face many problems kitting out your RV with a renewable energy source. Most kits come with all the adaptors and clips you’d need to wire your panels up to your battery in minutes.

What can I charge with solar power?

Well, that depends. But given the right setup, you could feasibly expect to run your RV’s appliances entirely on solar power, keeping its battery charged at all times, and ensuring the only stops you’ll ever need to make (aside of course for when you’re setting up camp) are at gas/petrol stations along the way.

Is the cost worth it?

Whilst some kits hardly cost more than filling up your tank the once, there are those which will make quite a dent in your wallet. And yet, that shouldn’t put you off – whilst it’s important to make sure you know what you need before you buy, so that you’re not paying more than you need – what you do pay now will pay off dividends years down the line, when a decade from now you’re still powering your RV’s aircon exclusively via solar power, and you find that kit you shelled out for ages ago has paid for itself twenty times over.

Where’s the best place to install my off grid solar panel system?

That also depends on the space you’ve got to use, but generally speaking, on the roof of your RV. You’ll actually find that, whilst during driving you’ll want them secured flat, to maximise exposure to sunlight, many kits can be fixed up to rigs which allow you, when stationary, to raise and tilt your solar system, angling it toward the sun either side of the RV.
