Re: BP Finds Large Oil Deposit In Gulf Of Mexico
Solar shingles are on the market now, but installation is a pain. You need to drill a hole behind each one into the attic, then have wiring troughs run under the roof every 12 inches or so to make all the connections in. The idea of solar double-coverage roll roofing would be very intriguing. Even competition/choice in the solar shingle market is a good thing.
One of the problems with solar roofing is heat. Electric output goes down as the cells heat up. With an airspace between the roof and standard panels, especially with cooling airflow, the panels can be more productive in summer than if they were nailed directly onto a hot attic. Still, it's much better than not having them, and much more pleasant to the eye in historic neighborhoods where appearance is a factor.
Someone said "Making good decisions comes from experience, experience comes from bad decisions." I say there are three kinds of people: those who learn from their mistakes, those who learn from the mistakes of others, and those who never learn.
