Solar panels are becoming increasingly popular, and you will find many more of them installed on caravans than you would just 10 or 15 years ago.

Some forward-thinking caravan owners have installed them on to their vehicles as a valuable power source, which can be particularly useful if you travel off-grid.

Solar panels have a reputation of being overpriced and difficult to install; however, this is beginning to change thanks to a few companies making them more accessible to the everyday consumer. It’s a trend we expect to see accelerate over the coming years.

By mounting solar panels, you can significantly reduce the chances of losing access to electricity – and thereby having to go without your essential appliances and devices.

In this guide, we’ve reviewed the best caravan solar panels and the features that you need to consider when investing in this popular step towards self-sufficiency on the road.

What to Consider When Buying a Caravan Solar Panel

Many of us have never purchased a solar panel – so what are some of the key product features we should be looking at?


A warranty is normally supplied with most caravan solar panels, and these will vary in length. The longer a manufacturer is willing to cover your product for, the greater the peace of mind.

There are usually two types of warranty offered:

Power Warranty

Power warranty refers to the amount of time that your solar panels will effectively produce power for. For example, a manufacturer may guarantee that your solar energy panel will generate energy for ten years at 90% of its total capacity. If its output drops below this, then the manufacturer will replace or repair your unit. 

Product Warranty

A product warranty covers the parts and components of the solar panel. If any of these breaks within the warranty period, then the manufacturer will replace at no added cost. Product warranties will range in length from 2 years to lifetime.

Solar Panel Brand

As you’d expect from any type of product, the brand will have a significant effect on not only the quality of the product but also the selling price.

The higher quality brands will likely be more energy-efficient and therefore command a higher selling price. You should view this as an investment because the better brand and product you purchase the more energy it will produce and you’ll save more money by using less grid electricity.


Unlike traditional solar panels that you see on residential homes, caravan solar panels are much cheaper because you’ll only have space for a few panels and they generate lower amounts of energy.

Generally, you can pick up a panel for £100-£200 each, and the price will be affected by the type, brand, efficiency and power output.

You’ll also need to understand if you can install these yourself. Otherwise, there will be additional labour costs for installation. However, most caravan solar panels are user-friendly and easy to install.

When you’re thinking about the initial financial outlay for your solar panels you need to consider this as a long term investment because now that you can produce your electricity, you’ll now save money by having lower energy bills.


Solar panel efficiency is an essential consideration because the higher the panel efficiency, the larger amounts of energy that it will produce for your caravan. Module efficiency is the reading that you need to prioritise when it comes to efficiency.

Modern solar panel efficiency is normally between 16 – 20%, and if it’s above 19%, then this is ideal. The higher the efficiency, the more expensive the solar panels will be.

You also need to consider the size of your roof because if you have a smaller roof, then you’ll need to be more energy-efficient panels. Whereas if you have a larger roof, then you can install a larger number of panels that have a lower efficiency.

Power Output

The greater the power output of your solar panels, the more electricity that your caravan will have.

Power output is measured in watts and caravan solar panels watts will be slightly lower than domestic residential solar panels – in our experience, usually around 100 watts.

You should ideally stick to an output of no less than 100w if you want to generate sufficient levels of electricity. The higher the wattage, the more expensive the panel will be to purchase, but this will be offset by the savings that you’ll make by not having to pay for electricity.

Types of Solar Panels For Caravans

In the solar panel industry, there are two main types that you can choose from which are monocrystalline or polycrystalline. Their names signify the type of silicone that the panels are made from. The type of silicone affects how efficiently they can generate energy for your caravan.

In terms of efficiency, monocrystalline panels are better performing, and you can also expect them to last longer, which means that they cost more, but it’s recommended to get this type of panel. If you’re on a tighter budget, then polycrystalline panels are still an option. 

Monocrystalline have a sleeker more attractive design due to often being black, whereas polycrystalline are generally blue. 

User Reviews

You can get a detailed description of a solar panel brands reputation and expertise by browsing through user reviews and websites. Never underestimate the power of reviews because solar panels are becoming more widespread, which means that more users are reviewing the quality of their products.

If you’re at a caravan park and see another caravan with panels installed, then don’t hesitate to ask them questions about their set up as this help you make a more informed decision. You can ask about installation, any issues, the brand and the amount of energy they generate.

Additional Components

If you buy a solar panel package, they will often come with other vital components.

For example, once your solar panel has been fitted, you’ll need to connect it to your caravan battery, but you need to ensure that it doesn’t overcharge your battery which can cause damage. To prevent this damage, you’ll need a charge controller which is sometimes referred to as a regulator. Some solar panels will come with this included saving you money and time so you can do a full installation at the same time.

Top Benefits of Caravan Solar Panels

Quick Installation

Caravan solar panels aren’t as complicated as traditional solar panels that you might see on the roof of a house. Many solar panel kits will come pre-assembled, so all you need to do is mount it onto the roof of your caravan. Others will have pre-drilled holes to make life easier, which means you can be up and running in just a few hours.

In most cases, you’ll be able to install yourself, so you don’t need to pay an engineer to come and fit them.

Reduces Energy Bills and Electricity Consumption

The cost of energy normally sees early increases which means it will cost you more to power your caravan appliances. You can protect yourself from rising utility bills by using solar panels as part of your energy consumption strategy. 

This will help to reduce your total energy bills even when traditional electricity increase. Once you’ve paid the initial outlay, the electricity is free which makes it significantly more cost effective than alternatives such as caravan generators.

Reduce Carbon Footprint

Changing to solar energy will drastically reduce your carbon footprint if you’ve been using mains electricity up until this point. Solar power energy is not only green but also renewable because it doesn’t release harmful chemicals such as Carbon Dioxide like traditional electricity generators do. Over their lifetime, your solar panels can save tonnes of CO2 from being released into the atmosphere.

Off the Grid Independence

Caravan owners often go off the grid where there may not be direct access to energy (via caravan hook up cables). Solar panels are ideal for this when you’re in remote areas where connecting to the electricity power grid can be expensive or complicated.

If you’re planning to go off-grid, then you can also integrate batteries into your solar power set up which provides you with a means of storing the energy which you can then use at a later time. For instance, if you wanted to use your stored energy through the night. There is a range of different batteries available, and they vary depending on their size and capacity.

All Year Round Use

It’s often a misconception that solar panels can’t generate power in the colder winter months. Their full energy generating capability is realised in the summer months, but during winter and cloudy days, they can still produce considerable and useable amounts of energy.

Low Maintenance 

Solar panels need little servicing and depending on the system; some need no maintenance. Solar panels are expected to last for up to 40 years and are usually covered by warranty for at least 20 years.

Once solar panels are installed, they will need to be kept clean, and often natural rain can help to keep them dust-free. If your solar panels do accumulate any dirt or debris, then they can simply be cleaned with a brush and hot water.

How to Fit Solar Panels to a Caravan

Once you’ve selected your desired solar panel system, you’re well on the way to saving money by using the power generated by the sun. Now you need to start thinking about the installation of the panels to the roof of your caravan.

You first need to check with your caravan insurer that installing solar panels doesn’t void your insurance deal. It may also be in the terms that the panels need to be installed by an approved company or need to be from the manufacturer of your caravan.

Once you’ve found this out, you can then decide whether you want to install them yourself or pay for a professional to install them.
