I'm thinking of doing a quick and dirty installation ofsolar panels on mydetachedgarage roof (roughly 20' x 12' installation area)and storage based oneither 18650 lithium ionbatteries ordeep cycle 12V sealed lead acid batteries. There's a 12/2 wire (20 amp circuit) ran from the house, buried through thebackyard to that detached garage (for the garage door opener).If I wanted tore-purpose that wire to insteadbring power from this potential garagesolar installationto the house, any idea,roughly,what is thebestpower, panels,inverter and battery configuration I can achieveconsidering this 12/2 wire will likely be the bottleneck?
