Why Consider Solar for Your Orinda Property?
Solar may be worth exploring if you want to generate electricity at your property and use some of that energy on-site. Whether a system is suitable depends on the property’s physical conditions, electricity use, and applicable utility arrangements.
Assess Your Roof and Available Sunlight
Orinda’s hillside terrain and established vegetation make a property-specific roof and sunlight assessment important. Tree shading, roof orientation, usable roof area, roof condition, and nearby obstructions can affect the layout and design of a solar PV system. We also consider whether roof repairs or other work should be addressed before installation. Roofing work is outside our electrical license classification and would need to be performed by an appropriately licensed contractor.
Review Your Electricity Use
Your electricity consumption throughout the day helps inform the proposed system size. Reviewing recent utility bills and usage history can help identify consumption patterns and provide useful information for system design.
Consider Battery Storage and EV Charging
Battery storage may be relevant if you want to use more of your solar generation after sunset or need backup for selected circuits. If you own or plan to purchase an electric vehicle, charging schedule and available electrical capacity should also be considered when planning the property’s energy equipment.

PG&E, Solar Billing and Electricity Credits in Orinda
The City of Orinda’s Utility Service Providers page identifies Pacific Gas and Electric Company (PG&E) as the provider of gas and electric service in the city. Confirm the utility account and applicable rate for your property on your current bill.
How Solar Generation Affects Your Electricity Bill
Electricity generated by a solar PV system can first serve the property’s electricity demand. When the system produces more electricity than the property is using at that time, excess electricity may be exported to the grid, subject to the system configuration and utility interconnection arrangement.
The value of exported electricity depends on the applicable utility tariff and compensation rules; export credits should not be assumed to equal the retail rate charged for electricity purchased from the grid.
California’s Net Billing Tariff
California’s Net Billing Tariff (NBT), also known as the Solar Billing Plan and sometimes called “NEM 3.0,” applies to qualifying new solar interconnections under the participating utility’s applicable rules. Under this arrangement, exported electricity receives credits based on the applicable export compensation rates, which may differ from retail electricity rates. The tariff and billing arrangements depend on the utility, customer eligibility, and interconnection date.
For further information, refer to the California Public Utilities Commission’s Net Energy Metering and Net Billing resource. You can also review the California Solar Consumer Protection Guide before entering into a solar agreement.
Solar Permits and the Installation Process in Orinda
Rooftop solar installation in Orinda requires the applicable building and electrical permits. The City of Orinda’s Building Permits page states that Planning Department review is not required for flush-mounted, roof-mounted solar installations on residential properties. The Contra Costa County Building Department is responsible for reviewing and issuing building permits for Orinda properties. Other city or agency requirements may apply depending on the property and project.
SolarAPP+ Eligibility in Orinda
Contra Costa County offers a SolarAPP+ automated permitting pathway for qualifying residential rooftop solar PV and solar-plus-storage projects. Not every property or system qualifies. The County’s published eligibility conditions include the following:
- The system must be installed on the main dwelling of a permitted residential structure; accessory-structure installations are not eligible.
- Ballasted systems and mobile home park installations are excluded.
- Properties in FEMA Special Flood Hazard Areas and registered historic properties are excluded.
- Properties within the Buchanan Field or Byron Airport Safety Zones are excluded.
- The parcel must have a valid street number and street name.
- For Orinda projects, applicants must also have an active City of Orinda business license.
This is a summary, not a complete eligibility checklist. Additional parcel, equipment, and project conditions may apply.
SolarAPP+ projects must be submitted by a licensed contractor who has previously registered with the SolarAPP+ platform. The automated pathway applies to qualifying residential rooftop PV and PV-plus-storage projects; commercial projects must follow the applicable permitting process.
For the complete requirements, review the Contra Costa County SolarAPP+ eligibility and permitting information. The County also provides an eligibility checklist for PV and PV-plus-storage systems.
Projects that do not qualify for SolarAPP+ must use the applicable standard permitting process.
