Off-grid officially as of March 4, 2011. Time elapsed since disconnect.
Webcam Since 1980 I have had a desire of being able to power my home independently from commercial power. The last 2 years I have been extremely close to achieving that goal. I was somewhat tentative to just call and cut the cord though. Over the last 12 months I used commercial power for a week or two last summer for air conditioning. As of March 4, 2011 it is now cold turkey. The initial goal is to go 12 months on our own. Twelve months was chosen because the local member owned co-op back charges anyone who is disconnected for less than 12 months for missed line charges. Sincerely hoping that I never have to resort back to depending on an external power provider. |

Note 1: Nov 5, 2011 - I was doing a panel check by turning off individual panel circuits whenn I noticed that one array was dead. Found that one of the AP-120's had a burn in the back covering about the size of a cigarette burn. Apparently there was a bad connection from the factory on one of the Cell interconnects. I think I was able to fix it. Cut through the covering and silicone. The burnt spot looked to be overheated but cleaned it up and resoldered. The cells on these panels have 2 tabs per side. Checking the connection on the other tab and it was open. Resoldered that and fingers crossed that it is corrected.Pictures of July 14, 2009 upgrade installation: upgrade

Sunelec miamiFor those that think nuclear power plants are our salvation. I strongly recommend they read the following book available from www.thenewpress.com. I have always had a gut aversion to the concept of nuclear power plants. After reading the book I have become even more against them. The only good nuclear power comes from the sun.

From way back when I found the pictures on the left. In 1980, while in college I became interested in solar power. I constructed a panel from 36 Radio Shack 1 amp cells that the local store had to call most of the other stores in the state. The cost was around 10 dollars per cell. I fiberglassed a plywood board and used silicone caulk to place the cells on the fiberglass. There was a lot of heat stresses and at the time I didnt really understand all the "right" ways to do it. It worked for about a year. I kept a plexiglass cover on them when I wasnt around. Even with that I accidentally left the cover off one day and some pea size hail obliterated it. I ran one light bulb and an Ten-Tec Argonaut 509 off of it.
This wind generator is located in Ashmore, IL.
