5 or 10W panel to keep generator battery charged
I'm purchasing a home that has a Generac generator that runs the well pump. The previous owner had issues with the generator battery losing charge between uses of the well. I'd like to as a small panel to the roof of the building to keep the battery topped off. The battery is a 12V with 675 cranking amps / 540 cold cranking amps. NAWS carries both a 5 and a 10 watt Solartech panel. Would the 5W be sufficient if I get plenty of sun?
