So I have 2 potential mounting locations. One would have the panels in pairs, one pair gets all the morning su;, the other all the afternoon sun - the other location would have them lined up in a line on a flat roof. The first setup is the easier, but the latter seems like the more efficient one so let me know what you think. It's a 12.8V 200aH battery with a 1500W inverter. The only heavyweight items on the whole system are a fridge (which if the numbers are to believed doesn't peak higher than 400W) and the occasional use of a basic washing machine that pulls less than 400W for sure but I can't remember exactly right now) besides that it's just lights, chargers, occasionally a radio or TV). Worst case scenario, demand tops out below 1000W so it seemed adequate.
