Here is how I spent my weekend in Dallas . . .
Helping Daniel and Doug Knoodle make a homemade solar panel, very cheaply. The cells provide a decent amount of power for a very low cost compared to most solar panels. They are just very easily broken though.
Now I should find a decent inexpensive grid-tie power inverter.
Update: 10/13/2009 – We found a good one. See my updated post about it.
