Whether you are considering rooftop solar, a home battery, or an EV charger, we can help you understand the options and requirements for your Sunnyvale property.

Why Consider Solar for Your Sunnyvale Property?
Solar panels allow you to generate electricity at your property. Depending on your electricity usage and utility rate, a solar system may also help you use more of the electricity you generate instead of purchasing it from the grid.
Whether solar is suitable for your property depends on several factors. Here are some things to consider before choosing a system.
Assess Your Roof and Available Sunlight
Roof orientation, shading, usable roof area, structural condition, and existing rooftop equipment can all affect solar system design and electricity generation.

In Sunnyvale, nearby trees, neighboring buildings, and roof layout may affect how much sunlight reaches your panels throughout the day.
A property assessment helps us determine whether your roof has suitable space and conditions for solar panels and whether any additional work may be needed before installation.
If your roof needs repairs, those should be completed by an appropriately licensed roofing contractor. Roofing work is outside our C-10 electrical contractor classification and is not automatically included in a solar installation proposal.
Understand Your Electricity Usage
Your electricity use throughout the day helps determine the right solar system configuration.

Reviewing your electricity bills can help identify:
- Monthly and annual electricity consumption.
- Daytime and evening electricity usage.
- Your current electricity rate and time-of-use periods.
- Existing electricity charges and usage patterns.
- Opportunities to use more of your solar generation onsite.
This information gives us a starting point for designing a system around your household or business electricity needs.
Consider Whether Battery Storage Is Suitable
Solar panels generate electricity when sunlight is available. A compatible battery can store some of that electricity for use later.

A battery may be useful if you want to use more of your solar generation in the evening or provide backup power to selected circuits during a grid outage.
The right battery configuration depends on your electricity usage, backup requirements, equipment compatibility, and utility billing arrangement. A battery does not automatically provide backup power to your entire property. The circuits supported and the length of time they can receive power depend on the system design and available stored energy.
Understand Sunnyvale’s Electricity Provider Arrangement
Sunnyvale is within the service area of Silicon Valley Clean Energy (SVCE).
Read moreRead less
If you receive electricity generation service through SVCE, SVCE supplies the generation portion of your electricity service, while Pacific Gas and Electric Company (PG&E) continues to handle electricity transmission and delivery. You generally receive one electricity bill from PG&E covering the applicable generation and delivery charges.
This arrangement is worth understanding when considering solar because your electricity rate, grid imports, solar exports, and battery use can all affect your bill.
Check your current electricity statement to confirm your generation service and applicable rate.

The project proposal and contract explain the agreed electrical work and any additional requirements.

PG&E, Solar Billing and Electricity Credits in Sunnyvale
Before choosing a solar system, it helps to understand how your electricity provider handles solar generation and electricity sent back to the grid.
Sunnyvale is within the Silicon Valley Clean Energy service area. If you receive generation service through SVCE, SVCE supplies your electricity generation, while PG&E handles transmission and delivery. You generally receive one PG&E electricity bill covering the applicable generation and delivery charges.
Check your electricity statement to confirm your current account arrangement and rate before evaluating a solar system.
How Solar Generation Affects Your Electricity Bill
Your solar panels generate electricity that can first be used to meet your property’s electricity demand.
If your system produces more electricity than your property needs at that time, the excess may be sent to the grid, depending on your system configuration and utility interconnection arrangement.
When your solar system does not generate enough electricity to meet your property’s demand, you may need to draw electricity from the grid.
The value of electricity sent to the grid depends on your utility tariff and applicable export-credit rules. Export credits should not be assumed to match the retail rate you pay for electricity imported from the grid.
California’s Net Billing Tariff – Solar Billing Plan (NEM 3.0)
California’s Net Billing Tariff (NBT), commonly referred to as the Solar Billing Plan or NEM 3.0, applies to qualifying new solar interconnections under the applicable utility rules.
For eligible SVCE customers with qualifying solar interconnection applications submitted on or after April 15, 2023, the Solar Billing Plan generally applies. The applicable billing arrangement depends on the utility, application date, interconnection status, and tariff eligibility.
Under this arrangement:
· Electricity generated by your solar system can first serve your property’s electricity demand. · Electricity imported from the grid is charged according to your applicable rate plan. · Excess electricity exported to the grid receives credits based on the applicable export-compensation rates. · Export compensation may differ from the retail rate charged for electricity consumed from the grid. · Battery storage may allow you to use more of your solar electricity onsite rather than export it.
If you already have a solar system, adding to or modifying the installation may affect how it is treated under existing utility billing rules. Check the applicable requirements before making changes.

What to Review Before Choosing a Solar System
Before deciding on a solar installation, review:
- Your electricity usage and billing history.
- Your current electricity rate and time-of-use periods.
- How much of your solar generation you expect to use onsite.
- Expected solar generation and possible electricity exports.
- Battery operation, if energy storage is included.
- Any remaining utility charges under the applicable tariff.
Your actual electricity bill depends on your usage, rate schedule, system performance, export compensation, and utility rules.
We do not provide our own projected savings estimates under NEM 3.0 because future electricity usage, consumption patterns, and customer behavior can vary. This does not replace or waive any standardized disclosures required under California solar consumer-protection rules. We provide the required disclosures at the applicable stage before the customer signs the solar contract.
Solar Permits and the Installation Process in Sunnyvale
Solar installations in Sunnyvale must meet the City’s applicable building, electrical, permitting, and inspection requirements.
The City of Sunnyvale offers a SolarAPP+ pathway for eligible contractors handling qualifying new residential rooftop photovoltaic installations.
SolarAPP+ is an online automated permitting application. Eligibility for this pathway depends on the contractor, project design, and the City’s published eligibility requirements. Projects that do not qualify may need to go through the City’s standard permit review process.
Separately, the City requires businesses engaging in or carrying on business in Sunnyvale to obtain the applicable City business license. This business-license requirement is distinct from SolarAPP+ eligibility. Meeting the business-license requirement does not, by itself, establish that a contractor or project qualifies for the SolarAPP+ pathway.
Contractors should confirm the business-license requirements that apply to their operations as well as the SolarAPP+ eligibility requirements for each project.
Battery storage, electrical panel upgrades, commercial solar installations, and other electrical work may have additional permitting and inspection requirements, depending on the project scope.
Official resources:
· City of Sunnyvale – SolarAPP+ for Solar Installers · City of Sunnyvale – Permit Center · City of Sunnyvale – Online Permit Services
Understanding SolarAPP+ Eligibility in Sunnyvale
SolarAPP+ is available for qualifying residential rooftop photovoltaic projects when both the contractor and project meet the City’s published eligibility requirements.
The City’s published process includes:
1. Submitting the solar system design through SolarAPP+. 2. Obtaining the applicable SolarAPP+ approval. 3. Applying for the City photovoltaic permit through the City’s online permitting system. 4. Completing the required permit application steps and paying the applicable City permit fee. 5. Displaying the permit documentation and arranging the required inspection after installation.
SolarAPP+ approval does not complete every City permitting or business requirement. Contractor eligibility, project scope, City business-license requirements, and any additional approvals must be confirmed separately before using this pathway.
This automated process does not necessarily apply to battery storage, commercial solar, or every type of electrical project.
