The Sizing Tool

How Much Solar Does My RV Need?

Answer a few questions about how you camp. We translate them into an estimated solar array size, lithium battery capacity, and inverter size. No wattage math required, and no obligation attached.

Question 1 of 7

How do you want to use your AC off grid?

How many AC units does your coach have?

What kind of fridge do you have?

Do you use a microwave or convection oven off grid?

How many hours of TV in a typical evening?

How many laptops charge daily?

How many days do you typically stay off grid?

See your numbers

Enter your details and we will show your estimate and have a technician sanity-check it against your coach. Your answers travel with your request, so the callback starts with real information instead of twenty questions.

Water pump and lights are always counted for every RV, so you do not need to add them.

How this estimate works

We assign each appliance a typical daily energy draw, with air conditioning weighted by how many hours you want to run it and how many units you have. Days off grid stretch the battery requirement, and Las Vegas sun hours set how much array it takes to refill the bank each day. The inverter figure comes from your largest realistic combination of simultaneous loads, with headroom for compressor startup surge. A technician then checks the estimate against your actual coach, because a brochure number is not a system design.
