Electricity Providers, Solar Billing, and Credits in Los Altos Hills
Understanding how your electricity provider handles billing is an important part of evaluating a solar installation.
Los Altos Hills is within the service area of Silicon Valley Clean Energy (SVCE). SVCE provides electricity generation service, while Pacific Gas and Electric Company (PG&E) delivers electricity through its utility infrastructure.
PG&E maintains the electricity delivery network and handles delivery-related utility services and billing. Your utility statement can help you confirm your account, applicable rates, and billing arrangements.
How Solar Generation Affects Your Electricity Bill
Electricity generated by your solar system can first serve your property’s electricity demand.
When your system produces more electricity than you are using at that time, excess electricity may be exported to the grid, depending on the system configuration and interconnection arrangement.
The financial value of exported electricity depends on the applicable utility tariff and its rules. Export credits should not automatically be assumed to equal the retail price you pay for electricity.
Your overall electricity bill also depends on the electricity you import from the grid, when you use electricity, applicable rates, and other charges.
California’s Net Billing Tariff and SVCE Solar Billing Plan
California’s Net Billing Tariff (NBT), commonly referred to as NEM 3.0, establishes how qualifying solar customers are credited for electricity exported to the grid. Participating investor-owned utilities refer to their program as the Solar Billing Plan.
SVCE also offers a Solar Billing Plan for eligible customers in its service area. The applicable program depends on when the customer applied for solar and the relevant utility account and interconnection requirements.
According to SVCE’s published guidance:
- Customers who applied for solar before June 29, 2016, are generally associated with NEM 1.0.
- Customers who applied between June 29, 2016, and April 14, 2023, are generally associated with NEM 2.0.
- Customers who applied after April 14, 2023, are generally enrolled in SVCE’s Solar Billing Plan.
Existing customers may remain under their applicable NEM arrangement for the relevant program period, subject to eligibility and program rules. Check your account and applicable tariff with SVCE and PG&E before making a purchasing decision.
Under the applicable net billing framework:
- Solar electricity can first serve your property’s electricity consumption.
- Excess electricity may be exported to the grid.
- Exported electricity receives credits under the applicable compensation rules.
- Export compensation may differ from the retail electricity rate.
- Battery storage may allow you to use more of your solar generation onsite rather than exporting it.
The applicable billing treatment depends on your utility account, program eligibility, application and interconnection dates, and system configuration.
A battery may change how much solar electricity you use onsite. Whether adding storage is suitable depends on your electricity consumption, rate schedule, equipment cost, and usage patterns.
What to Review Before Choosing a Solar System
Before evaluating a solar installation, review:
- Your electricity usage and billing history.
- Your applicable SVCE and PG&E rate arrangements.
- Your time-of-use periods.
- The amount of electricity used during daylight hours.
- Your expected solar generation and possible exports.
- Battery storage requirements, if applicable.
- Any remaining utility charges under the applicable tariff.
The actual impact on your bill depends on usage patterns, rate schedules, system performance, and utility rules. It may also change over time.

Solar Permits and Installation Requirements in Los Altos Hills
Solar installations in Los Altos Hills must comply with the Town’s applicable building, electrical, and permitting requirements.
The Town provides a SolarAPP+ permitting pathway for eligible new rooftop solar photovoltaic systems and related work that meets its requirements. SolarAPP+ uses software to automate part of the plan-review process. It does not remove the need to meet applicable requirements or complete required inspections.
SolarAPP+ Eligibility in Los Altos Hills
According to the Town’s published SolarAPP+ application information, the streamlined pathway applies to eligible new rooftop solar photovoltaic installations on:
- Detached one- and two-family dwellings.
- Townhomes.
- Related accessory structures, such as garages and accessory dwelling units.
Eligible systems must be 38.4 kW or smaller. Related energy storage systems and service-panel upgrades may be included when the project meets the applicable eligibility requirements.
The Town’s published application identifies restrictions for properties with code cases, service requests, voided permits, or locations within flood zones. These property records may affect eligibility and should be reviewed before selecting a permit pathway.
Homeowners cannot submit projects directly through the SolarAPP+ contractor pathway. The Town identifies B-General, C-10 Electrical, and C-46 Solar Photovoltaic contractors as eligible license classifications. Contractors must also register and become certified through SolarAPP+ before submitting applications.
We hold a C-10 electrical contractor license, which is among the classifications identified by the Town. However, SolarAPP+ registration and certification are separate requirements. A project should not be assumed to qualify for this pathway until the property’s eligibility and the contractor’s registration status have been confirmed.
Projects that do not meet the eligibility requirements must follow the applicable Town permitting and review process. SolarAPP+ eligibility should not be assumed for commercial installations, ground-mounted solar systems, or other projects outside the stated requirements.
For contracted projects, we coordinate the applicable permitting process and required project documentation. Your project agreement identifies any information or actions required from you. Final permit approvals and inspection decisions remain with the Town or other applicable authority.
