A property assessment should consider:
- Roof orientation and usable installation area.
- Shading from mature trees and nearby structures.
- Roof condition and structural suitability.
- Existing rooftop equipment and potential obstructions.
- Electrical equipment locations and installation access.
A solar panel orientation and shading assessment helps determine a suitable panel arrangement and proposed system size.
If roof repairs or replacement are necessary, they should be completed before solar installation where appropriate. Roofing work is outside our C-10 electrical contractor classification and must be performed by an appropriately licensed roofing contractor.
Tree removal or trimming should not be assumed to be permissible to improve solar access. Check the Town of Atherton’s current heritage-tree and tree-protection requirements before undertaking such work.
Match the System to Your Electricity Usage
Your electricity consumption throughout the day helps determine the appropriate solar system configuration.

A review of your electricity bills can help identify:
- Monthly and annual electricity consumption.
- Daytime and evening usage patterns.
- Current electricity rates and billing arrangements.
- Energy requirements from existing appliances and equipment.
- Expected changes in electricity consumption.
If you plan to add an electric vehicle, battery storage, or other electrical equipment, include those requirements in the system design.
Consider Battery Storage and Future Energy Needs
A battery may be useful if you want to store some of your solar generation for later use or provide backup power to selected circuits during an outage.
The right configuration depends on your electricity usage, utility billing arrangement, backup requirements, equipment compatibility, and budget.
Solar and Energy Solutions Available in Atherton
We offer several solar and electrical services. The right combination depends on your property, energy requirements, and project objectives.
Residential Solar Panel Installation
A residential solar PV system converts sunlight into electricity that can be used by your home.
Read moreRead less
Our residential solar installation process considers:
- Electricity consumption and usage patterns.
- Available roof area and orientation.
- Shading from trees and nearby structures.
- Solar panel and inverter selection.
- Existing electrical infrastructure.
- Applicable permitting and utility interconnection requirements.
For homes with mature trees or multiple roof sections, system design should account for available sunlight and the usable installation area.
We develop the proposed system around your property’s conditions and actual energy requirements rather than relying on a generic system size or promising to 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
Battery storage options should be evaluated based on:
- Expected electricity consumption.
- Battery capacity and usable stored energy.
- Inverter and system compatibility.
- Electrical circuits that require backup.
- Expected backup requirements.
- Utility billing arrangements and equipment costs.
A standard grid-connected solar system generally shuts down during a utility outage for safety. Solar panels alone do not normally keep a standard grid-connected system operating during an outage.
A compatible battery and properly configured backup equipment may allow selected circuits to remain powered. Backup availability and duration depend on the battery, inverter, backed-up circuits, system configuration, available solar generation, and connected loads. Backup power is not guaranteed during every outage.
If you already have solar panels, we can assess whether your existing system and electrical infrastructure support adding battery storage. Changes to an existing installation may also affect its treatment under applicable utility billing rules.
Commercial Solar PV Systems
Businesses may consider commercial solar PV systems to serve part of their electricity consumption and make use of suitable installation areas.

A commercial solar assessment should consider:
- Operating hours and electricity consumption patterns.
- Existing electricity billing arrangements.
- Available roof area and structural condition.
- Electrical infrastructure and service capacity.
- Equipment requirements and installation access.
- Utility interconnection and applicable permitting requirements.
The proposed system size, expected generation, and financial implications should be evaluated using the property’s actual electricity and project information.
EV Charger Installation
We provide EV charging installation based on your vehicle, charging schedule, and property’s electrical infrastructure.
Read moreRead less
Before installation, we assess the charger type, electrical capacity, wiring requirements, and whether an electrical panel upgrade or other work is necessary.
Solar panels and EV charging can also be evaluated together. The amount of solar electricity available for vehicle charging depends on system generation, charging times, and other electricity requirements at the property.
Electrical Panel Upgrades
Some solar, battery storage, and EV charging projects require modifications to the existing electrical infrastructure.
Read moreRead less
We assess the electrical panel and available service capacity to determine whether they can support the proposed equipment.
Any electrical panel upgrade or related work is based on the project’s technical requirements and applicable electrical codes. The proposed electrical work and its scope are identified in the project proposal and agreement.
PG&E, Peninsula Clean Energy, and Solar Billing in Atherton
Understanding your electricity provider and solar billing arrangements is an important part of evaluating a solar installation.
The Town of Atherton identifies Pacific Gas and Electric Company (PG&E) and Peninsula Clean Energy (PCE) in its electricity and gas information.
Atherton residents are automatically enrolled as Peninsula Clean Energy customers. PCE provides electricity generation, while PG&E owns and maintains the electricity delivery infrastructure. Customers receive a consolidated electricity bill from PG&E.
Check your current electricity statement to confirm your generation service provider, account arrangements, and applicable rates before making a solar installation or financial decision.

How Solar Generation Affects Your Electricity Bill
Electricity generated by your solar PV system can first serve your property’s electricity demand.
When your system produces more electricity than your property uses at that time, excess electricity may be exported to the grid, depending on the system and interconnection arrangement.
When your property’s electricity demand exceeds solar generation, additional electricity is supplied through the grid.
The financial value of exported electricity depends on the applicable utility arrangement and export compensation rules. Export credits should not automatically be assumed to equal the retail electricity rate.
California’s Net Billing Tariff and NEM 3.0
California’s Net Billing Tariff (NBT), commonly referred to as NEM 3.0, is also called the Solar Billing Plan by participating investor-owned utilities.
For qualifying new interconnections, the applicable billing and export-credit arrangements depend on the electricity provider, tariff eligibility, and interconnection date.
Under the Net Billing Tariff, exported electricity receives credits based on applicable export compensation rates. These rates may differ from the retail rate charged for electricity consumed from the grid.
For Atherton properties, it is important to distinguish between Peninsula Clean Energy’s electricity generation service and PG&E’s electricity delivery service. PCE customers should review the applicable PCE solar billing arrangements and any relevant PG&E delivery charges for their account.
A battery may change how much solar electricity you use on-site rather than export to the grid. Whether storage is suitable depends on electricity consumption, rate arrangements, battery costs, and backup requirements.
What to Review Before Choosing a Solar System
Before evaluating a proposed solar configuration, review:
- Your electricity usage and billing history.
- Your current generation service provider.
- Applicable electricity rates and delivery charges.
- Time-of-use periods.
- Expected on-site electricity consumption.
- Expected solar generation and electricity exports.
- Battery operation, if energy storage is included.
- Remaining utility charges under the applicable tariff.
Actual bill impact depends on electricity usage, generation, utility rates, export compensation, system performance, and applicable utility rules.
We do not provide savings estimates under NEM 3.0 because individual electricity consumption and future usage behavior cannot be predicted reliably.
