Started Aug 8, 2012 0 Replies

Not to long ago I quickly discovered a small inverter doesn't have the nads to run a regular size vacuum cleaner. And the 18v battery operated vacuum works but is a pain to use for a camper floor /…Continue

"Yes I did in fact, good mention. They would use less power but far less heat in return. I don't know if they would even function in sub freezing temps."

"I try and brush the snow off the panels when I can to give them a fighting chance but they are all ground/stand level. Not sure what the guys with roof mounted arrays are doing. I mean it's going to take a while for melt off to begin with. "

Another Solar Power Goal Achieved!

Posted on September 6, 2012 at 7:00pm 0 Comments

Refrigeration, no Ice at Camp! It took a quarter kilowatt to do it but I’m very pleased. Actually closer to 300 watts but that’s beside the point. I’m able to keep food, beer, and beverages cold & fresh now just using Solar Power my system generates. No more soggy foods. I don’t have to drain coolers or toss plastic ice bags into the trash. I use the thermoelectric chiller to transport to and from and a …

Well I may have used my last HF coupon for a kit today. Took advantage of an inside track coupon and bought one final metal frame kit. I've become friends with one of the cashiers, when the kits would go out the door she would say something like 'the guys love `em.' Well after a breif conversation about the changes she wasn't so sure anymore.

This gives me 10 15w panels in total. And the truth is where I use them amorphous makes more sence. So I should have the amps I need now. The…

This should give me about 4-5 amps on good days peek hours. The singles come with some extra hardware, disconnect wiring & 3 adaptor connections. Also if I consider or need to…
