I've made my first panel. 63 watts. It works. I learned what to do by watching Youtube videos. Mainly, I just wanted to know how to do it. It wasn't very expensive. Now, I can make more panels when I get spare cash. I'll expand my system over time with no financing to worry about. I'm powering PC monitors and some lights right now. I just need to expand my battery bank. I've made a small wind turbine, also, to help charge the batteries.
