Solar electricity cost (4 points) The typical crystalline Si panel fabrication cost is $150/m2, and the typical panel power conversion efficiency is 15% with a typical lifetime of 25 years. Assume all the other cost items for an installed roof-top solar panel system is about 150% of the panel cost. In Gainesville, we get about 2000 hours per year sunlight at standard AM1.5G power (1 kW/m2). Calculate, over the lifespan of the solar panels, how much is the cost of the solar electricity in cents per kWh. (4 points)
