In this sense it is a great estimate to start by sitting down and notice how much excess power you need (realistically) that solar panels create their RV for you. How much power is going to run? What is the power of your TV, fan, blender, etc, and how long you want to operate each of them in one day. If you suppose you will be 800 watts, for example, to install up to four plates. If you live in less sunny climates, you may need more than.

The optimum and smartest estimate is to gain a deep cycle electric battery (or two or three) to that charge when the sun reflects and the investor, so that you can link directly and use of solar energy collected, when you need it even if it is dark outside and rain.

Still, make for sure your RV batteries and solar panel charge controller charges the meters and turn it off before overcharging the battery. Aside from an extra battery indicator is invaluable. Otherwise, you run the hazard of advance reduction in the lifetime of your RV batteries, solar panels.
