I've done my entire system from start to finish 100% by myself. About 9 months ago I knew nothing about solar other than solar panels made electricity from the sun. Between watching Will Prowse, Engineer775, Gain Solar (all three on YouTube), online information and this forum, I was able to learn enough to properly size and install a system. It was an enjoyable process from start to finish.
I was thinking what if's. Like what if buy a shed from the place down the street that sells garden sheds. Turn that into a battery shed, run a heavy wire gauge from the shed underground to the home. I have no idea what size wire it would require, would depend on how much power you're pushing. Plus, just don't know if its that much of a concern to go to the trouble of doing. I see some guys online that have a power shed, it has everything , batteries, inverter, the whole deal in the shed, and they run AC power over to the home. That would be a great way to protect your home from fire but I didn't go that route.
The problem with almost any project now is cost of materials. A pack of bacon is $6 and a gallon of gas is $4. Not sure it's going to come back down any time soon or if at all now that the people selling the stuff know consumers will pay it.
