CHARGING A BATTERY WITH A SOLAR PANEL?
Feb 4th
Question by Conrad:
Charging a battery with a solar panel?
I have a boat with an automatic bilge pump, and I want to hook up my battery ( 12 volt deep cycle marine) to a solar panel so that it maintains its charge when the bilge pump kicks on, the bilge pump will only kick on when it rains. I want to know what minimum specs the solar panel should have to maintain my batteries charge. The bilge pump will likely only run for an hour or two a week at most. Thanks in advance for the help.
