Why use solar energy to power my RV?

Unless you have been hiding under a rock for the past ten years it will be no surprise to you that there is an increasing need for us to invest in renewable energy. Our fossil fuel consumption has reached alarming rates and if we want to continue with our electricity habits we need to look towards energy sources that protect our environment rather than harm it. A solid argument for opting for solar energy as a means to fuel your RV dreams.
Investing in solar energy also has great financial incentives as well as environmental. While the initial set up of a solar system in your RV may seem a little pricey, the energy you then generate from it is completely free. Eventually, you may break even on your solar energy investment and your pockets will thank you for the savings you have made by not using as much mains electricity.
Aside from the environmental and financial incentives, using solar energy is also incredibly convenient. We all know how frustrating it is to be out in our RV and be unable to find anywhere to power dock it. With a solar energy system your electricity comes from the skies, and with the solar panels on the roof you will actually be generating electricity while you are driving (as long as it’s not too overcast!).

What is a solar power kit?

You can buy all of the elements for your RV solar system individually, but with a solar power kit, these difficult decisions are made for you. With the solar kits reviewed in this article, you can rest assured that the products have been thought about carefully and that they will work in harmony together. They will also provide you with the essentials to get you started on your solar energy adventure.

What is included in a solar power kit and how do they work?

Most solar power kits will come with a solar panel (or panels), a charge controller and an inverter. Not all of the solar power kits reviewed here come with an inverter, but you can easily select one from our article Best Inverter for RV. You will also need a battery to store the solar energy in if you need one of these check out our article on the Best Battery for Solar RV.
So, what do these items actually do and how do they work together? Let’s take a look at each of them individually to give you a better idea:

Solar Panels

the solar panel will sit on the roof of your RV and, when they receive photons, or light particles, these will cause atoms to release electrons and thereby create a flow of electricity.

Charge controller

the electricity generated by the solar panel then passes through the solar charge controller which regulates how much energy your battery receives. This is necessary to protect the battery from receiving a surge of energy when the solar panels are in direct sunlight, and when the sun isn’t shining it protects the battery from discharging to a low level. Overcharging and undercharging can both damage the battery so the solar charge controller is essential in preventing these occurrences.

Battery power inverter

the energy that has travelled from the solar panel, through the charge controller into your battery is DC power. In order to use this power in your electrical devices, this needs to be changed into AC power (this is the energy that is supplied to your home). This is done through an inverter which converts DC power into AC power. Another option for AC power is Best Portable Generator for RV.

What do I need to think about before buying a solar kit for my RV?

In the solar power market, there are different degrees of technology, with some products being more advanced and, subsequently, more expensive than others. Before deciding whether you want to splash the cash on your solar energy kit, or would prefer to go for a more modest set-up, it is a good idea to think about the following key considerations.


Thinking about the location your RV will most frequently be sitting or driving in is essential when it comes to choosing a solar kit with the most suitable solar panels for your needs. Despite what you might think, solar panels do not always need direct sunlight in order to gather energy and there are some types of solar panels that are better suited to environments where shade is a more common occurrence than sunshine.
Step up the Monocrystalline solar panel, being formed of a single-crystal silicon this solar panel is super efficient. When in direct sunlight it ensures that it makes the most of those rays and is able to generate an ample amount of electricity. This efficiency makes it the best option for days where the sun is hiding behind a cloud, and a good option if you are travelling in an environment where sunshine can’t be relied upon.
The alternative and cheaper option is a Polycrystalline solar panel. These solar panels are made up of multiple fragments of silicon rather than a single-crystal like the Monocrystalline – this means the electrons that create the electricity flow from the sun have less room to manoeuvre, meaning this type of solar panel produces less power. This feature also means they are not as well equipped to deal with sun-deprived days. Nevertheless, don’t write Polycrystalline solar panels off just yet, they are more than sufficient if your power needs are low, or if you can guarantee your RV will be exposed to sunshine.
Another option is an Amorphous solar panel, also known as thin-film solar panels, are created by spraying silicon onto glass in thin layers. This type of solar panel is cheaper than Polycrystalline solar panels but are slightly less efficient.

How often will you be relying on your solar kit?

Another key factor to consider is how often you will be needing to rely on solar power as your main energy source. This will impact on both the type of solar panels and type of solar charge controller to look out for to ensure the best RV solar set up for you.

Rigid or flexible solar panels?

You will notice that solar panels come in different formats – either rigid or flexible. If you are planning on going off-grid regularly then it is likely to be a worthwhile and economical choice to invest in some rigid solar panels.
Rigid solar panels are the type that sit proudly on top of the roof of your RV and can be titled to ensure they are facing the sun. They can be a little tricky to install (as they require some drilling and bolting so they can be attached to the roof) but once they’re secured their sturdy aluminium frame means they are incredibly durable and can withstand bad weather.
A rigid solar panel is also less susceptible to overheating as air can flow underneath them ensuring the solar panel doesn’t get too hot which reduces efficiency and can cause possible damage. Very important if you need a lot of energy from your solar panels and maybe leaving your RV in a sunny spot for lengthy periods of time.
However, if you are looking for a straightforward solar set up, and are planning on using solar power every now and then for short camping trips a couple of times a year, then a flexible solar panel is a good choice. This type of solar panel can be bent to fit the shape of the roof of your RV and then very simply glued on. They are much lighter than the rigid alternative and are also good power generators. Be wary of their potential to overheat though as the lack of air-flow underneath them makes this a possibility.

PWM or MPTT solar charge controller?

When it comes to selecting the best RV solar kit with the most appropriate charge controller the best way to decide is to, again, think about the frequency with which you will be relying on your solar energy system in your RV.
The cheapest option on the market are Pulse Width Modulation (PWM) solar charge controllers. These tried and tested devices ensure that your battery does not overcharge by controlling the voltage and current that flows from your solar panel to your battery.
A more advanced solar charge controller comes in the form of the Maximum Power Point Tracking (MPPT) device. It does the job of the PWM solar charge controller and then goes one step further. Where PWM controls the charge until it meets the voltage size of the battery and then maintains it, the MPPT is able to use any excess energy generated by the solar panels that your battery cannot immediately handle by turning it into extra current and then uses the power at a lower voltage – optimising the energy from the sun in the most efficient way.
MPPT solar charge controllers are a lot more expensive than the PWM alternative, but if you are going to be using your RV solar set up regularly this would be a good choice to ensure you make the most of the suns rays.

How much power is needed?

The next thing to think about is your power needs. You might just need some solar energy to ensure you can make your cup of coffee in the morning and have the lights on at night. Or you could need your RV to be your home away from home and require your solar set up to power up your AC system, your microwave oven, your lamps, your laptop, flat-screen TV and smartphone all at the same time.
Your power needs are individual to you so the best thing to do is work out the combined amperage of your devices – they should have the number of amps used listed on them and then you can use an energy calculator to work out how this translates into volts (just google ‘energy calculator’ and you will find hundreds!).

Solar panels – which voltage size do I need?

Now you’ve got that sorted it’s time to think about the size of the solar panel you should select in your solar kit to match your energy requirements. Solar panels are rated by voltage, those that have a higher voltage will be able to generate more electricity. It is also the case that the larger surface area the solar panel has the more of the suns energy it can soak up.
For short camping trips in your RV every few months, a 12-volt solar panel will be sufficient. Whereas, if you will be using your solar kit daily to power multiple devices in your RV then you should be looking at kits that have a solar panel rated at 24 volts (and you might want to think about having more than one solar panel).

Inverters – what wattage rating should I choose?

There is no point having a high voltage solar panel and big battery if your inverter doesn’t match your energy requirements. This is because the inverter converts the DC power you have stored in your battery (thanks to the solar panels) into AC power that your onboard devices need to function – and the watt rating of the inverter needs to match the energy needs of all of your electronic devices combined.
Again, you can use an energy calculator to work out the combined wattage of your electronic appliances and this will help you to select an inverter with a sufficient watt rating. Make sure you go for an inverter with a slightly higher wattage than you actually need (around 10% higher) so you can be confident that the inverter can cater to your power needs and make the most of the free solar energy your RVs solar panels have generated.

What devices will you be powering?

If you are going to be using your solar kit to power expensive devices such as a laptop, smartphone or flat-screen TV you no doubt want to make sure that the power you send to these devices is clean and won’t damage them. It is crucial to consider this before selecting a solar kit with the right type of power inverter for your needs.
You may have heard of pure sine waves and modified sine waves. Pure sine waves are distributed in even waves, whereas modified sine waves come in square waves. Pure sine waves are, as their name suggests, a ‘purer’ form of electricity that is more efficient and will not cause damage to the devices it powers. Modified sine waves are less pure and therefore less efficient, they may also damage more sensitive devices and are known to create an annoying buzzing sound in some electronic appliances.
Inverters come in two different types – modified sine wave and pure sine wave with the latter, understandably, being more expensive. Making an investment in a solar kit with a pure sine wave inverter is an economical choice if you are going to be powering more expensive items as you won’t be needing to replace these earlier than planned as the energy delivered to these will be clean. A modified sine wave inverter will work fine if you just want to power the essentials – such as your kettle and lights.


If you are thinking about investing in a solar energy kit for your RV then you have already realised the benefits of this free and renewable energy source. The solar kits reviewed here highlight how easy it is to set up such a system in your RV and you will soon realise how well suited solar energy generation is suited to the outdoor lifestyle.
Make sure you think about your energy needs so that you select a solar energy kit that has the correct types of solar panels, charge controller and inverter that are suitable for you. Once you are set up with the essentials, we are confident that you won’t look back and will be reaping the benefits of this free energy source for years to come.
