What to Consider Before Installing Solar in Fremont
Solar installation suitability varies from one property to another. Reviewing a few important factors before choosing a system can help you understand the options available.
Review Your Electricity Consumption
Monthly and annual electricity consumption, daytime and evening usage, and seasonal changes help determine the appropriate solar system configuration. Future requirements, such as electric vehicle charging or additional appliances, should also be considered.
Assess Roof Condition and Available Sunlight
Roof orientation, slope, shading, and usable installation area influence rooftop solar PV design. The roof’s structural condition and expected remaining life should also be evaluated. If repairs are needed, it may be preferable to address them before installing solar panels.
Evaluate Battery Storage Requirements
A battery may allow excess daytime solar generation to be used later. Whether storage is appropriate depends on electricity consumption, utility rates, equipment costs, export compensation, and backup-power requirements.
Consider Electrical Infrastructure and Future Needs
The existing electrical panel, wiring, and available capacity can influence solar, battery, and EV charger installation. If you plan to add an electric vehicle, appliances, or other electrical equipment, include those requirements in the initial assessment.
Understanding Electricity Providers and Solar Billing in Fremont
Before installing solar panels in Fremont, it is useful to understand how electricity generation, delivery, and exported solar electricity are handled.
Ava Community Energy and PG&E in Fremont
Fremont is served by Ava Community Energy for electricity generation for customers enrolled in its service. Pacific Gas and Electric Company (PG&E) continues to provide electricity delivery services.
The two providers have different responsibilities:
Ava Community Energy: Provides electricity generation service to enrolled customers.
PG&E: Provides electricity delivery through its distribution infrastructure.
Ava generation charges and PG&E delivery charges appear on the customer’s PG&E bill. The applicable generation plan can vary, so review your bill to confirm your current arrangement.
California’s Solar Billing Plan (NEM 3.0)
California’s Net Billing Tariff (NBT), commonly referred to by participating investor-owned utilities as the Solar Billing Plan or NEM 3.0, determines how eligible new solar customers receive compensation for excess electricity exported to the grid.
Read moreRead less
Under this arrangement:
- Solar electricity first serves the property’s electricity demand.
- Excess electricity can be exported to the utility grid.
- Export compensation is based on applicable export rates.
- Export credits are generally different from retail electricity rates and vary by time.
The value of exported electricity can influence how a solar system should be designed. The applicable billing arrangement depends on the customer’s utility, tariff eligibility, and interconnection date. Generation-related export compensation for customers served by Ava Community Energy may differ from PG&E’s, so review current Ava and PG&E program details.
How Battery Storage Fits Into Solar Billing
A battery can store excess solar generation for use when solar production is lower, including during evening hours. Its potential financial benefit depends on electricity consumption, battery costs, applicable utility rates, export compensation, and system configuration. Battery storage should therefore be evaluated according to the property’s actual energy requirements rather than treated as a necessary addition to every solar installation.
Fremont Solar Permits and Installation Process
Solar panel installation in Fremont requires applicable permits, inspections, and utility interconnection approvals. The permitting route depends on the project design and the City’s current requirements.
Fremont Solar Permits and SolarAPP+
The City of Fremont provides an Instant Solar Permit (ISP) pathway through SolarAPP+ for eligible new residential rooftop solar PV and energy storage systems. A main electrical service upgrade can be included in the ISP.
The pathway is available only to contractors registered with SolarAPP+, and only systems that meet the City’s current eligibility requirements qualify. Projects outside the eligibility criteria, including ground-mounted and commercial systems, must follow the applicable standard permitting process.
Nabu Energy manages the applicable permitting process for its contracted installation projects. This includes preparing and submitting required project documentation and coordinating with relevant authorities. The required permits, review process, and approvals depend on the project scope and applicable local requirements. Final permit approval remains subject to the relevant authority’s review.
For current requirements, refer to the City of Fremont Instant Solar Permit information.
