In this article, we will be showing you some information about solar panels, and we made a list of the best ones to charge your RV’s battery, just for you. 

How do solar panels work?

Solar panels go through a process known as Photovoltaics (PV) after they capture sunlight. They convert the sunlight directly into energy, which then goes through to the charge controller and is fed to the battery. Solar panels are actually made of numerous photovoltaic cells.

The power that the solar panels generate will be stored in the battery, which will be accessible in two days.  

Immediate access is only available for appliances that operate on a 12 volt DC, but most of the appliances require 110 volt AC power. To converter the current from DC to AC, we recommend an inverter.
