Solar Questions
I am trying to figure out what I need to recharge a battery in an average 8 hours of sunlight per day with a maximum load of 2.52 amps. This is an exercise in building a system which hopefully will...

Considering the short winter sunlight hours, I would guess lights will be on 12 hours a day, 2.52 amps X 12 hours = 30.24 AHs. Yes it will be used 365 days a year. We are on top of a hill and no trees to block the sun. I haven't decided on tilt but most likely the 3-1 pitch of the roof. We are about 25 miles in a straight line across the Los Angeles basin from the beach, with the CL of the house running East West and a large roof that is South facing, so we have good exposure.
My figures are my current usage plus additional 100 percent. I currently have 5, 921 LED at 90 lumen or 0.84 amps and one 921 LED at 240 lumens or 1.68 amps. I am designing with that 100 percent fudge factor in case the DW wants more lighting.
Am I looking at a full size 12 volt WLA battery or a motorcycle battery? If I remember the two GC2's in the MoHo are 210 AH. Do I just look up for example Interstate and find a 70 or 75 AH battery or is a 35 AH battery in the ball park?
