Solar Commercial Thermal Services

Commercial Thermal Solar Hot Water

Many states offer tax credits in order to promote clean energy.  These tax credits differ by state, but in California as of October 2010, the current rebate is $12.82 per therm or $0.37 per kWh up to a maximum of $1,875. The total incentive is based on a combination of the performance rating of the solar water heater, the orientation of the collectors (you will receive closer to the maximum rebate if they are facing true south), your regional climate, and whether the solar panels will be shaded (collectors should be shaded as little as possible)

Large-scale multi-family and commercial solar water heating system may receive up to $500,000 if they are displacing natural gas or up to $250,000 if they are displacing electricity.
