Fitting a solar panel to a motorhome is very straightforward. It’s a great way to enhance your holiday experience. Solar panels are a reliable source of free energy and will reduce your dependence on mains hookups.

So how do you start? What items do you need?

You will need a solar panel, a charge controller and some cable. You will also need one or two other items. We’ll cover those later.

Which solar panel should I choose?

For a motorhome, we recommend you fit a solar panel of at least 50 watts. This will keep your battery in good condition, especially while you are not using the van. To increase your independence of the mains hookup you should consider using a solar panel of at least 100 watts. If you want to run lots of appliances at the same time, consider connecting two 100 watt panels together to make a 200 watt solar panel array.

Watertight cable gland.

You must allow a small gap underneath the solar panel to allow air to circulate. This is easily done using SunWorks PVC solar panel mounts.

To lead the cable securely through the roof of your motorhome, use a SunWorks roof cable gland.

The connection to your battery must be fused correctly. Use a SunWorks fused battery harness to make the job easy.

A tube of Sikaflex 252i adhesive will ensure that your PVC mounts and roof gland are very securely attached to the roof of your motorhome. Sikaflex 252i is extremely strong and weatherproof.

And finally, use a few ties to secure the cables both externally and internally.
