I spotted a freshly remodeled house in my neighborhood the other day. It had a large array of shiny new PV solar panels on the roof. Wouldn't it be great to be able to afford such things? Wouldn't it feel great to watch your electric meter spinning backwards?
You don't see many solar panels in Seattle. It piqued my curiosity, so I found a solar cost calculator to find what it would cost to replace my electricity use with panels. The answer is about $160,000 dollars (taking about half a century to break even).
