  1. Mount the solar panels:

If you’re wondering how much solar power you need for your campervan or motorhome, check out our blog post here where we can help you work out how much you need – How Much Solar Power Do I Need In My Motorhome / Campervan?

How much power can I expect to generate from my solar panels?

The amount of power generated depends on factors like panel efficiency, sunlight hours, and panel angle. As a rough estimate, a 100-watt solar panel can produce around 30 amp-hours per day in ideal conditions.

Can I install flexible solar panels on
my campervan?

Yes, flexible solar panels are a great option for campervans with curved roofs or limited space. They’re lightweight, easy to install, and can conform to the shape of your vehicle’s roof. Just keep in mind that they might be less efficient and durable than rigid panels.

How do I maintain my solar panels?

Solar panel maintenance is generally minimal. Regularly check the panels for dirt and debris, and clean them with a soft cloth and mild detergent when necessary. Also, inspect the mounting system, wiring, and connections for any signs of wear or damage.

Can I run my air conditioner with solar power?

Yes, it’s possible to run an air conditioner on solar power, but you’ll need a larger solar system and battery bank to accommodate the high energy consumption of the appliance. It’s best to consult a professional to determine the ideal system size for your specific needs.
