My Neighbor Is Into Solar Power

One of my neighbors installed a solar water heater a few years ago - it wasn't terribly fancy or huge. He's a guy who's a do-it-yourself type, very handy with tools and construction, and after looking into the facts about solar energy, he purchased some supplies and rigged up the heater one weekend. I don't know all the technicalities, but he tells me it works fine and has cut his electric bill by 30%.

Well, now he's talking about having a solar power system installed on his roof. He knows a lot about the tax incentives being offered by the government. After listening to him talk at length about this, I'm starting to wonder whether I should invest in some solar cells myself. My power bill is higher than his because my house is bigger and I have more kids. I also own and operate a large warehouse that really consumes a lot of power every month. I'd like nothing better than to lower the utility bills there.

My neighbor got really excited when I mentioned this to him, and since then I've been getting an earful of suggestions. I'm starting to think I'd better go ahead with the installation because he'd be terribly disappointed if I didn't!
