Home Power Article: PV. vs. Solar Thermal - Simple Solar Payback

A great article comparing the payback and efficacy of Photovoltaic (PV) and Solar Thermal systems. With Solar thermal coming out as the huge winner. For example the cost of energy according to this article for PV is $0.27 per kWh and Solar Thermal is $ 0.09 on a national average. System payback for a PV system starts at 22 years and Solar Thermal starts around 9 years in Virginia alone. Average cost of a PV system $20,000 and Solar Thermal $8,000. A great read!
