Solar Power

Last modified: 4/3/2015 12:01 PM

Are you looking for ways to reduce energy consumption, reduce greenhouse gas emissions, and save money on your energy bills in the long run?  Solar thermal and solar electric energy generation are becoming an increasingly popular and viable way to do all this and more.

Solar power is an important part of the Santa Clara County Climate Change & Sustainability Program.  We are committed to using renewable energy at County facilities and encourage homeowners, business owners and other entities with the unincorporated areas of the county to do the same.

Use the links below to get more information about the kind and size of system is appropriate for your building, rebates and incentives, suppliers, contractors and much more.

Note: The solar insolation (kWh/m2/day) values on these maps is somewhat different from values shown on maps available though the National Renewable Energy Laboratory and other sources. The Planning Office calculated the values shown on these maps by factoring in terrain and southern exposure.
