Adding solar panels to your home or business can help reduce your monthly electricity bill. There are many programs and resources to help individuals and businesses go solar. However, it is important to always make energy efficiency improvements first. Energy efficiency is the most cost-effective way to reduce electricity bills and improve comfort. The less energy a house uses, the smaller and less expensive the solar equipment required.

City Receives Gold Designation for Advancing Solar


The City of Walnut Creek has been awarded a SolSmart Gold designation for our efforts to make going solar faster, easier, and more affordable! We are proud to be recognized as a national leader in advancing solar energy. Funded by the US Department of Energy Solar Energy Technologies Office, SolSmart recognizes cities and counties for streamlining permitting and making solar more affordable and accessible for homes and businesses. We are committed to reducing solar energy costs at the local level and encouraging even more homes and businesses to use this clean, affordable energy source. The SolSmart Gold designation recognizes that we are making our community more solar-friendly and environmentally sustainable. 


Why Go Solar?

  • Reduce or eliminate your monthly electricity bill

  • Potentially increase your property value

  • Install proven, mature technology

  • Choose from a variety of financing options

  • Reduce your carbon emissions

  • Protect yourself from future electricity price fluctuations

  • Enjoy low maintenance once it’s installed

Getting Started

  • Looking to install solar panels? EnergySage connects consumers with multiple solar energy quotes and financing options from multiple contractors through an easy-to-use web platform. These options enable consumers to choose the right solar option for them. Just enter your zip code to get started! Visit the EnergySage website.

  • PG&E's Solar Calculator helps you estimate the costs of installing solar and the savings on your electric bill you’d get from  a solar PV system.

  • MCE electricity customers can learn about MCE's net energy metering program and rates for rooftop solar.

  • Google Project Sunroof uses Google Earth Mapping, combined with solar orientation, roof segment angles, weather conditions, and more to give you a quick assessment of whether solar is a smart investment for your household, business, or municipality

Permits & Building Code Requirements

Visit the Building Division's webpage for a checklist of solar requirements for a permit:

State Laws on Solar Access and Solar Rights

  • Learn about the Solar Rights Act and Solar Shade Act here. The Solar Rights Act was created in 1978 (AB 3250, 1978); it created a legal framework for solar access. The law includes protections to provide consumers access to sunlight (and prevent shading of systems) and to limit the ability of homeowner associations (HOA) and local governments from preventing installation of solar energy systems.

  • AB 634 was passed in 2017 and helps resolve issues in state code related to the installation of rooftop solar in common interest developments. This bill prohibits homeowner associations from establishing a general policy prohibiting the installation or use of a rooftop solar energy system for household purposes on the roof of the building in which the owner resides, or a garage or carport adjacent to the building that has been assigned to the owner for exclusive use. The bill also makes approving solar projects easier and provides protections to homeowners sharing roof space with homeowners installing solar panels.

Federal Solar Investment Tax Credit

In December 2016, Congress approved extending the Solar Investment Tax Credit, which currently provides a 30 percent federal tax credit for solar systems installed on residential and commercial properties. This tax credit was set to expire at the end of 2016, but is now extended through the end of 2019, helping to keep solar affordable for homeowners and businesses here in Walnut Creek. After 2019, the tax credits have different expiration dates and values by year for residential and commercial projects. For more information about tax credits, see the Financing page.

New Net Energy Metering Policy

On January 28, 2016, the California Public Utilities Commission (CPUC) ruled in favor of extending California’s net energy metering (NEM) program. Net energy metering allows customers with on-site renewable energy generation, like solar, to receive a financial credit for excess power generated by their systems.

For the most part, the decision is seen as largely preserving many of the benefits of NEM for future solar customers. New solar customers will need to pay a one-time interconnection fee ranging from $75 and $150, and some additional charges. Utilities would place new NEM customers on time-of-use rates, which rise during periods of high electricity demand. The new NEM program will take effect for new solar customers after the utilities reach certain participation caps, or July 1, 2017, whichever occurs first. Existing solar owners are exempted from all the NEM changes for 20 years from when they installed their systems and connected to the grid. For more information, visit PG&E's website.

More Resources

  • Renewable energy can include solar, wind, biomass, hydroelectric, or geothermal power, and can help significantly reduce greenhouse gas emissions. Under California's Renewable Portfolio Standard, investor-owned electricity and natural gas utilities, like PG&E, are required to derive 33 percent of their energy mix from renewables by the end of 2020.
