Why Consider Solar for Your Cupertino Property?
Solar panels allow a property to generate electricity from sunlight. Whether a solar PV system is suitable depends on your property’s characteristics, electricity consumption, and utility billing arrangement.
Here are some factors to consider before choosing a system.
Assess Your Roof and Available Sunlight
Roof orientation, shading, usable roof area, structural condition, and the location of existing equipment can affect the size and performance of a rooftop solar system.

During a property assessment, we review the available installation area, look for potential shading issues, and determine whether the roof needs attention before installation.
If roof repairs are necessary, they should be completed before solar installation where required. Roofing work is outside our C-10 electrical contractor classification and must be performed by an appropriately licensed contractor.
Understand Your Electricity Usage
Your electricity consumption throughout the day helps determine the appropriate solar system size.
Reviewing your electricity bills can help identify your usage patterns, current utility rate, and periods of higher electricity consumption. We use this information when evaluating a proposed system.
Consider Battery Storage Requirements
Solar panels generate electricity when sunlight is available. A battery can store some of that electricity for later use.
Whether battery storage makes practical sense depends on your electricity usage, utility rate, system configuration, battery capacity, equipment cost, and backup-power requirements.
Review Your Electrical Infrastructure
Your existing electrical panel and service capacity must be suitable for the proposed solar, battery, and EV charging equipment.
Some installations require electrical modifications or a main electrical panel upgrade. We assess these requirements during the property review and include any agreed electrical work in the project scope.
Plan for Electric Vehicle Charging
If you own or plan to purchase an electric vehicle, consider your charging requirements alongside your solar and electrical needs.
We review your charging schedule, charger requirements, available electrical capacity, and whether a panel upgrade or other electrical work may be necessary.
Solar and Energy Solutions Available in Cupertino
We offer several energy-related services for residential and commercial properties. The right combination depends on your property’s electrical requirements and project goals.
Residential Solar Panel Installation

When designing a proposed system, we consider:
- Your electricity usage and billing history.
- Roof layout, orientation, and available sunlight.
- Solar equipment and inverter selection.
- Existing electrical infrastructure.
- Applicable electrical and permitting requirements.
We design the proposed system around your property’s requirements. We do not promise that solar installation will eliminate your electricity bill.
Solar Battery Storage Installation
A home battery stores electricity for use at another time. Depending on the system configuration, it may help you use more of your solar generation after sunset and provide backup power during a grid outage.
Read moreRead less
Backup capability depends on the battery, inverter, electrical configuration, backed-up circuits, and available stored energy. A standard grid-connected solar system generally shuts down during a utility outage unless it is designed and configured for backup operation.
Backup power is not guaranteed during every outage.
A battery assessment considers:
- Which appliances or circuits you want to support.
- Your expected electricity usage.
- Battery capacity and configuration.
- Required backup duration.
- Compatibility with your existing solar equipment, if applicable.
Commercial Solar PV Systems
Businesses in Cupertino may consider commercial solar installation based on their electricity consumption, operating schedules, and available installation areas.

A commercial assessment considers:
- Business electricity usage and operating hours.
- Roof condition and available installation space.
- Existing electrical infrastructure.
- Site access and installation requirements.
- Proposed system configuration and equipment.
- Applicable permitting and utility interconnection requirements.
We evaluate the proposed system size, expected generation, and project requirements using the available site and utility information.
EV Charger Installation
An EV charging installation can be planned around your vehicle, charging schedule, and property’s electrical capacity.
Read moreRead less
Before installation, we assess the charger type, available electrical capacity, wiring requirements, and whether a panel upgrade or additional electrical work may be necessary.
If you are considering an EV charger alongside solar, we can review how the charging schedule, solar generation, and household or business electricity demand may affect the amount of solar electricity available for vehicle charging.
Electrical Panel Upgrades and Related Work
Some solar, battery, and EV charging projects require changes to the existing electrical infrastructure.
Read moreRead less

The written project proposal and agreement describe the agreed electrical work and any exclusions.
PG&E, Silicon Valley Clean Energy, and Solar Billing in Cupertino
Understanding your electricity provider and solar billing arrangement is an important part of evaluating solar panel installation in Cupertino.
Customers enrolled with Silicon Valley Clean Energy (SVCE) generally receive one monthly electricity bill from Pacific Gas and Electric Company (PG&E). The bill includes SVCE generation charges and PG&E delivery charges. Check your current electricity statement to confirm your service arrangement and applicable rate.
SVCE provides electricity generation service for participating customers, while PG&E delivers electricity through its utility infrastructure.
How Solar Generation Affects Your Electricity Bill
Electricity generated by your solar system can first serve your property’s electricity demand.
When solar generation exceeds your immediate usage, excess electricity may be exported to the grid, depending on your system configuration and utility interconnection arrangement.
The value of electricity exported to the grid depends on your applicable utility rate and billing rules. Export credits should not automatically be assumed to equal the retail price you pay for electricity.
California’s Net Billing Tariff and NEM 3.0
California’s Net Billing Tariff (NBT), commonly known as NEM 3.0, applies to qualifying new solar interconnections under the applicable utility rules. Investor-owned utilities refer to their implementation as the Solar Billing Plan.
For eligible SVCE customers, the applicable program is SVCE’s Solar Billing Plan. Customers who applied for solar after April 14, 2023, are generally enrolled in this program, subject to the applicable participation requirements.
Under the Net Billing framework, electricity generated by your solar system first serves your property’s electricity demand. Excess electricity exported to the grid receives credits based on the applicable export compensation rates. These rates may differ from the retail rate charged for electricity consumed from the grid.
A battery may change how much solar electricity you use onsite versus export. Whether adding storage makes practical sense depends on your electricity consumption, utility rate, equipment costs, and usage patterns.
Your billing arrangement may depend on your utility, service account, solar application or interconnection date, and applicable tariff. Review your current utility information before choosing a system.
Review Your Electricity Bill Before Choosing a System
Before evaluating a solar installation, review:
- Your electricity usage and billing history.
- Your current generation service provider and applicable rate.
- Available time-of-use periods.
- The amount of electricity expected to be consumed onsite.
- Expected solar generation and possible exports.
- Battery operation, if energy storage is included.
- Any remaining utility charges under the applicable tariff.
Under the NEM 3.0 and Net Billing framework, your electricity bill after solar installation will depend on your usage and how your system operates. We do not make generalized savings promises. We can review your electricity usage, system requirements, and applicable utility information to help you understand the proposed installation.
