I built a small solar system a couple months back patterned off of a youtube link I've posted elsewhere. It consists of a lawn tractor battery, a simple 12v charger/maintainer from SunForce, and a Black and Decker inverter. With a winter storm about to pummel the east coast in the next couple days, I thought it would be a good time to test it out.
I'm currently pointed directly north which is far less than ideal (solar panels in the northern hemisphere should be pointed south), but I'm still picking up charge anyways. If we lose power, I'm planning on running a space heater in my room from the system and maybe a string of LED's or charging my iphone.
I will let you all know how it works!
