To get the best use from your Camper & not having to rely on an electric supply, the best accessory to get is a solar panel to charge your leisure battery or batteries. So let’s have a look at some of the best solar panels for campervans.
How Does a Solar Panel Work ?
An electric current is created when the sun rays hit the solar panel. The electric current flows through a charge controller, which controls how much of the current goes down to the battery or batteries.
Solar panels give a steady charge to your batteries, in exactly the same way as your battery charger works, when you are on “electric hook up. Which is how batteries are supposed to be charged & it maximizes the life of your batteries.
If a battery sits for too long when it’s flat, it loses its battery life and it may not be able to hold a charge even after being charged back up
The batteries produce DC power for all the 12 volt systems on the campervan, such as lighting, water pump, fridge, TV, radio & maybe an inverter. Inverters change the power from DC into AC power. AC power is what runs things like your toaster, hair dryer, laptops, and phone chargers etc.

What Different Kits Are There ?
You can get solar panel kits that are specially designed to fit converted vehicles with Pop Top roofs like VW T4/T5/T6 and many more.
Solar panels for campervans are different than other kits due to the difference in aesthetics and weight restrictions.
Pop-tops and semi-flexible panels work well when mounting a solar panel on a campervan roof. Use a semi-flexible solar panel to reduce weight and hide it out of sight.
These Kits come complete with everything that you need for an easy installation.
There is a choice of Charge Controllers with many of these kits. These controllers are the most important part of any solar charging system.

Something You should Know –
Most people don’t realize that with a cheap kit, when they claim a panel is capable of 600w, that is when the sun is directly above the panel on the sunniest day for a decade in the sahara desert or in a science lab.
The rest of the time you are lucky if you average 40w & so your batteries go flat if you have a week of cloudy weather.
A proper solar panel, kit with the correct charge controller, will look after all of your batteries, all of the time.
This is from their own product description – Note:
“The labeled 600 W is the peak power calculated based on the chip, and it is only possible to test accurately under strict laboratory conditions.
When used under general conditions, the output power may not reach 600 watts due to the limitation of temperature and sunshine. Under normal circumstances, this solar panel is completely ok for charging mobile phone batteries, car battery, and other batteries of 12V/24V and below.”

Would I Get a Solar Panel ?
Simple answer – Yes. Which begs the question, why would you not ?
Many people see solar panels for campervans as one of the most important things to have on their van. I have a motorhome with a solar panel on it & we did 9 days stationary on a beach Aire in the South of France, without running out of power.
If you travel abroad & use the 11000+ Aires in France for example, you can tour indefinitely without having to physically plug your campervan into the mains electricity, just to charge your batteries.
Closer to home, every day your campervan will be getting a charge to its batteries wherever it parked up outside. You can free/wild camp or take a basic pitch on a site with no EHU & not have to worry about your batteries going flat. A solar panel with a decent all important charge controller, will keep your batteries in tip top condition & over time will pay for itself & save you money.
