What size solar panel do i need for my rv.

Yes your solar system can grow on your rv as money and budget allow. Our final personal determination. Using a charge controller rated in the 30 amp range will allow a single panel system to grow to three 190 watt panels. That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox.

The number of solar panels you need on your rv roof will also depend on how heavily you use the electricity you re generating. I don t know too many people who rv under those conditions. The main purpose of your solar panels will be to charge your rv house batteries. The main limiters of system size will still be in control of the maximum system.

For our specific power demands we need one 100 watt portable solar panel to recharge our rv batteries during our boondocking camping trips under normal conditions.
