Using the tutorials in the Alternative Energy Store site (which is excellent by the way!), I have determined that I'll need a single Uni-Solar 32 watt solar panel ($187), A MorningStar SunSaver Charge Controller, model 20L-24 ($94), and four Trojan T-105 batteries ($320).
With that, I have four questions: 1) Do my estimates look accurate, 2)What is a low cost inverter that would do the job, 3) I had trouble using the tutorial to figure out the best gauge of wire, what should I use, and 4) Without the inverter, I'm already at $600. That's getting expensive to simply add some power to a shed. Is there a more cost efective way to do this or am I overestimating something?
