How many solar panels do I need for my RV?

Most RVs need 200-600W of solar depending on usage. A typical setup with fridge, lights, and phones needs about 300W. For heavy AC or appliance use, consider 600W or more.

What size battery bank do I need for RV solar?

Calculate your daily Wh usage and divide by 12V. For 50% depth of discharge (recommended for battery longevity), double that number. Most RVs need 200-400Ah of lithium battery capacity.

How do I calculate peak sun hours for my location?

Peak sun hours vary by state and season. Arizona averages 6.5 hours while Washington averages 3.8 hours. Our calculator uses accurate data for all 50 US states.

What is the best solar panel size for RVs?

100W and 200W panels are most popular for RVs. 100W panels are easier to install on curved roofs, while 200W panels provide more power per panel, reducing the number needed.

Do I need a solar charge controller for my RV?

Yes, a charge controller is essential. MPPT controllers are 20-30% more efficient than PWM and worth the investment for systems over 200W.
