How much do panels cost per sq. foot? I think we should revisit nuclear power. Our harbors are home to Navy reactors anyway. Here are some rough numbers for you -- this isn't really my area, but... 1. A coworker told me that a large installation without batteries is about $10 per peak W of production. He also said that it takes about 11 sq. meters to generate 1 kW peak power. 2. A friend at BP Solarex told me the cost is closer to, or even less than, $7 per peak watt. So, using the $7 number, the installation cost is about $650/sq. meter. The coworker (who has done the calculation for 10,000 sq. miles) gave me a couple useful details: the calculation assumes 50% coverage by the solar panels, and assumes an 11% conversion efficiency. For the location used (somewhere in NV), the annually-averaged "insolation" is around 5.0 kWh/m^2/day. So make what you will of the situation -- my understanding is that even with state subsidies (buy-downs), people who install rooftop PV do so at least as much out of beliefs as out of hope for cost recovery.
