Hey Everyone, I really like this site and I'm trying to help it get
momentum to build a strong community of experts so it'll be a good
place for people to get their questions answered:

Nice site that I'll visit often. I hope to see more do-it-yourself
articles. Here's someone who built his own solar panel and a wind turbine.
This company sells solar cells.
They have DIY solar panel kits, and it looks like the starter kits are the
better deal. The advanced kits have extra components that appear pretty
worthless. I'd be more inclined to buy just solar cells, not the kits. You
can get 100 2-watt cells for $69.99. That's 200 watts for a fraction of
the cost of a commercial panel. A 200-watt panel here ...
... costs between $37.50 and $96.00. You have the cost of making the
panel enclosure, but plywood and Plexiglas are cheap. I'm considering
getting 150 2-watt cells and making four 72-watt, 18-volt panels. That
would leave me with a few extra cells in case of breakage.

There are some good deals these days on factory-built. Here's one for
$.18 per watt.

Thanks. Even with shipping, that is a good price. Buying a commercially
made panel at that price would be a much better deal than building my own.
The cost of just the solar cells would only be about $.46 per watt if I
bought 150 2-watt cells, but the cost of the materials to make four 72-watt,
18 volt panels would bring the total close the Sun panel's $.18 per watt.
Furthermore, the Sun panel would probably last 25 years or more, but who
knows how long my homemade creation would make it. That same website has
Kyocera's 130 watt panel for $26.40 or $.28 per watt, so it pays to shop
