The City of Palo Alto Utilities (CPAU) is a trusted, unbiased source of information for commercial customers looking to learn more or install a solar photovoltaic (PV) system. Read on to learn how CPAU can help your business take advantage of solar energy.

Solar PV Systems

Solar photovoltaic (PV) or solar electric systems convert sunlight into electricity for your building. Whether you are just starting to consider solar PV, are an existing solar customer or are a contractor working with a Palo Alto business, we have the resources for you.


Installing a commercial solar PV system in Palo Alto? Here's what you need to know.

The City of Palo Alto requires all contractors installing commercial PV systems within City limits to apply for a PV Permit and receive Final Interconnection Approval (also known as "Permission to Operate").

The City of Palo Alto Utilities (CPAU) is the municipal utility that oversees PV rebates, Net Energy Metering programs and Interconnection agreements, while the City of Palo Alto Building Department processes PV Permits and issues final PV system approvals.

Feed-In Tariff Program - CLEAN

Palo Alto CLEAN (Clean Local Energy Accessible Now) is a program to purchase electricity generated by renewable energy generation systems located in CPAU’s service territory, which coincides with the city boundaries. Programs like this, known in the industry as "feed-in tariff" programs, involve a utility paying a fixed price (tariff) for the power that is "fed into" their electric grid from local generation systems.
