Try an outfit called "Real Goods". They are a bunch of old hippies who
started out with a lot of alternative energy products. They are now into
consumer goods, but I believe they still do solar. Their older catalogs
have a lot of planning information in them. At one time they were
trying to sell some older used panels that a power company offed when
they shelved a project. It was many years ago, but they may still have
some left.

Running fluorescents is a snap with solar. Any bigger load gets complex
and expensive fast.

Good Luck,
Mike
