RVers install solar panels for two main reasons:
1. to trickle charge house batteries
2. as a source of primary electrical power
Solar Power Trickle Charging
When your RV sits for a prolonged period of time, your house batteries begin to lose power – regardless if they’re used or not.
For car owners this is the reason a battery dies after the car sits idle for too long.
The same principle applies to your RV. It’s also important not to leave the batteries dead for long periods of time as this could cause permanent battery damage – and leave them unable to hold a charge ever again.
All that’s needed to avoid much of the pain associated with a dead battery is a solar trickle charger. This charger will also keep your batteries fully charged and ready to go when the time comes to use them.
A solar trickle charger is usually a stand alone device that creates several watts of power for charging and maintaining RV house batteries.
These chargers are usually made of durable plastic and amorphous solar cells (more on that below), and are molded into a weatherproof unit that’s about a foot and a half square.
Installation is simple and straightforward.
Just take the small panel, usually no larger than a dinner plate, and connect the wires and battery clips.
Place the panel in the sun.
