Caravan Solar Panel Installation Guide

Imagine this: you find yourself in the heart of remote wilderness, far from the buzz of city life. The calmness and serenity surround you as you park up your caravan and immerse yourself in the beauty of nature. However, as the day unfolds and the sun sets, you realise that your power source is dwindling faster than anticipated. You don’t have sufficient electricity to power up your caravan. You need power to charge your camera and phone, or power other essential things that are necessary for your comfort and safety.

Many travellers will recognise this all-too-familiar scenario. The vital need for a reliable power source becomes abundantly clear, but what is the solution? Installing solar panels on your caravan. 

Fitting a solar panel to a caravan can provide uninterrupted sustainable power, harnessed from sun energy, to power up your caravan and charge your essentials. 

Let’s take a look at caravan solar panel installation and how to fit solar panels on your caravan roof…

Types of caravan solar panels

Before going into the details of caravan solar panel installations, you should first understand the different types of solar panels suitable for caravans. 

Rigid frame panels: As the name indicates, these are rigid solar panels that you can install on the roof of your caravan. They are strong and durable, but they are heavier than flexible solar panels and do not offer the same benefit of portability. 

Semi flexible panels: These are mostly thin-film solar panels. They are flexible, lightweight, and durable. They are also portable and easy to install – you will just need an adhesive to attach or use the grommets on the panel, so there’s no need for drilling and permanent mounting. They are a good option for fitting to a caravan that has a pop-top roof. 

Free-standing panels: These are portable solar panels that you can place on the ground beside your caravan while you’re parked up. They are made of two hinged panels that you can fold into a briefcase and carry anywhere. These solar panels are self-contained and compact, and you can connect and disconnect them to your caravan’s battery with ease. 

If you are thinking of fitting solar panels on a caravan roof, then Sunstore Solar provides a range of industry-leading solar panels for caravans. Speak to one of our experts for help choosing a solar panel kit.

What are caravan solar panel kits?

For fitting a solar panel to a caravan roof, the solar panel kits for caravans offered by Sunstone Solar are a perfect solution for a hassle-free caravan solar panel installation. These kits typically include solar panels, a charge controller, cables, and mounting hardware. They are specially designed to work seamlessly together as they ensure component compatibility. 

Remember to choose a kit that meets your energy requirements. For instance, if your energy requirement is 100W, then you need a panel that can produce more than 100W to power all your appliances effectively. You can use a simple 12v solar panel calculator to work out the amount of Watts you need.

Can you fit solar panels to a caravan roof?

Yes, you can fit solar panels to a caravan roof. 

The roof of the caravan is an ideal place to install solar panels as it’s perfectly positioned to receive maximum sunlight throughout the day.

However, it’s essential to consider factors such as roof material, orientation of panels, weight distributions, and the mounting structures you intend to use, in order to select the right solar panels for your caravan roof.

Fitting a solar panel to a caravan

Fitting a solar panel to a caravan requires careful planning and attention to detail. If you are installing a free-standing solar panel, then it takes just a matter of minutes to set up and use. All you need to do is take it out of the protective carry case, set it outside the caravan facing the sun, and connect the cable to your battery.

On the other hand, installing rigid frame solar panels requires some skills and knowledge as you have to drill holes on the roof of the caravan to mount and fix panels on it. 

But with a caravan solar panel kit, you won’t need any fancy tools and all the components will be included, as well as a handy installation guide. All you will need is a few hours of your time and some elbow grease!

Semi flexible solar panels are a little different but tend to be easier to install than rigid frame panels as you can use special adhesives and/or stainless steel grommets to fix to the roof of your caravan. 

Here’s how to install both rigid frame and semi flexible solar panels to your caravan…

Fitting rigid frame solar panels to your caravan

Step 1: Purchase caravan solar panel kit

The first step in caravan solar panel installation is purchasing all the required components. You can purchase a caravan solar panel kit from Sunstore Solar which includes everything you need for fitting a solar panel to a caravan roof.  

Step 2: Cleaning the roof

Make sure that the roof of the caravan is clean. If it is dusty or has debris over it, then use warm soapy water and a clean sponge to clean the surface ready for installation. 

Step 3: Select the mounting location

Choose a suitable location on your caravan roof for the solar panels. Ensure no obstructions on both the interior and exterior walls like roof racks, vents or lighting are in the way.

Step 4: Carefully drill the roof

You need to drill holes in the roof to install the mounting brackets and run the cable into your caravan to connect it to the battery and other electrical systems. So, measure up your panels and accurately mark the positions to carefully drill the hole in the right places. 

Step 5: Secure the panels

Attach the mounting brackets to the panels and then secure them to the roof, making sure to apply a layer of silicone sealant to prevent leaks.

Step 6: Thread the cable through

Once you have fixed the panel on the roof, pass the output of the cable into your caravan.

Step 7: Install the controller

Installing a controller is necessary to prevent the battery from overcharging and over discharging. Mounting it inside a cupboard near the battery is a good way to keep it out of sight but still easily accessible.

Step 8: Install the battery

Now, connect your battery to the controller. Keep in mind the positive and negative terminals while making all the connections.

Step 9: Connect the controller

In step 6, you threaded the output of the panel into your caravan. Now, connect it to the controller and then provide electricity to the caravan by connecting the output of the controller to the caravan’s electrical circuit. 

Step 10: Test your setup

Before hitting the road, test your solar panel system to ensure it’s working correctly and efficiently charging your caravan’s battery. 

NOTE: Solar panels produce DC, so you need to convert it into AC to power your appliances that operate on AC. This means you’ll need an inverter to connect to your battery and convert DC into AC. 

How to install flexible solar panels on a caravan roof

Installing semi flexible solar panels on a caravan roof is similar to that of traditional panels, with the added benefit of flexibility and lightweight design.

Semi flexible solar panels don’t normally need drilling or permanent mounting to install, you can just use a specialist adhesive to bond to the roof’s surface or use the stainless steel grommets in the panel to attach to the caravan roof for easy installation and removal. 

The semi flexible panels from Sunstore Solar have standard quick connect cables and come with an easy-to-follow installation guide for simple installation, along with all the components you need for fitting a solar panel to a caravan.

Conclusion

The installation of a solar panel on a caravan roof provides you with green energy to power up your caravan and charge your electrical appliances, without the need for an electrical hookup on a campsite pitch. It gives you the flexibility to roam off-grid without worrying about power problems.
