What size solar panel do I need to trickle charge my RV battery?
In most cases, a 200 to 400-watt solar panel setup will be enough to charge your RV batteries, providing there is direct sunlight. At the bottom end of the range, a 200-watt system should be sufficient for basic power needs – lights, fans, propane appliance electronics, phone chargers, etc.
Do solar trickle chargers work?
Yes, solar battery trickle chargers work as well as, if not better than, standard trickle chargers. They are particularly useful if you are in a rural area and are not near a standard power outlet. These devices will steadily charge the battery that they are attached to as long as they are exposed to sunlight.
Can I leave a solar trickle charger on all the time?
