Solar Panel Question.

kentuck_8bOctober 12, 2013

I have a 235 watt solar panel and want to use it to charge(using a charge controller) two 6 volt 220ah batteries connected in series, or 12 volt system.

I will be using no more than 60ah max daily but closer to 50ah or less. Is this alright using this solar panel, or is there something else I should be considering? Maybe a smaller wattage panel could be used also.

I have read that a good rule of thumb is to use a solar panel that has 1 watt of power for ever 2 amps of battery storage...does this sound right?

Thank you for reporting this comment. Undo

Maybe two 250 watt panels would be better since that would give ne 40amps.

Can someone also recommend an MPPT charge controller?
