Check out our Truma 100W SolarSet solar panels, perfect for when you're not in reach of a campsite electric hookup or you just want to go green and generate your own free electricity. Lights, water pumps, TV’s and even your fridge can be run from solar. Using a solar panel for your caravan is an ideal way to ensure that your battery is maintained to the highest standard. After the winter period of little to no use, the solar panel will also ensure that the battery is not flat.

How many solar panels do I need to power my caravan?
A fully fitted out caravan would need power for lighting, a fridge, television, possibly air conditioning and an inverter. This setup needs around 50-100Ah per day (depending on how long you have the TV on!) and a standard 100W solar panel will generate around 20Ah of charge a day.
So we reccomend fitting 3-4 solar panels to the roof of the caravan to be completely free and self-sufficient. Of course, having any solar panel will help minimise your carbon footprint and allow for backup power when you need it.
How do solar panels work?
When sunlight hits the solar panel, the photovoltaic cells within the panel are activated. The energy from the sunlight creates an electric current (by freeing electrons) within the cell. This can be carried away, inverted into AC current and fed into a caravan battery or directly into your caravan electrics.
