- Solar output changes with the seasons Sunny summers boost production, while winter clouds and shorter days reduce it; California incentives and export credits have separate rules.
San Jose Electricity Prices
For San Jose households, rising electricity prices make understanding local energy options increasingly relevant.
California’s average electricity price climbed from 22.8 cents per kWh in 2021 to 31.9 cents in 2024. The national average also rose, from 13.7 to 16.5 cents per kWh.
A solar system can generate some of a home’s electricity, reducing how much it needs from the grid. That may limit exposure to future utility rate changes, though results depend on usage and system design.
Over time, producing electricity at home may help offset utility purchases and make energy costs more predictable. Actual savings vary with rates, household consumption, equipment, and applicable utility rules.
Price of Energy: California vs National Average
San Jose Area Utility Providers
In San Jose, PG&E serves many households. The latest figures available are from 2023: PG&E electricity averaged 34¢ per kWh, compared with California’s 29.50¢ and the national average of 16¢.
These are different kinds of benchmarks: PG&E’s figure reflects its utility rates, while state and national averages combine rates across many areas. Because rates vary by utility and location, PG&E’s 2023 average was above both benchmarks.
Higher electricity rates can increase the potential value of solar by helping offset electricity bought from the grid. The actual benefit depends on a home’s energy use, solar production, and applicable utility billing rules.

| CAEATFA Sales and Use Tax Exclusion (STE) for Approved Projects | Sales and Use Tax Exclusion | Approved participating parties may receive a sales/use-tax exclusion for qualifying alternative-energy, distributed-generation, or storage property purchased for an approved project; it is not a general household solar exemption. | Learn More |
| California Solar Billing Plan / Net Billing Tariff | Net Billing / Solar Export Credits | New eligible rooftop solar customers in PG&E, SCE, and SDG&E territories receive bill credits for electricity exported to the grid under the Net Billing Tariff, with credit values varying by export timing rather than matching retail rates one-for-one. | Learn More |
SGIP’s Residential Solar and Storage Equity (RSSE) offering provides incentives for eligible residential solar-and-battery projects. Published maximum rates are up to $1,100 per kWh of battery storage and $3,100 per kW of paired solar; the actual incentive is limited by eligible project costs, system-sizing rules, and program requirements.
Eligibility is generally for income-qualified California households, including households at or below 80% of area median income or customers who qualify through specified programs such as CARE, FERA, ESA, SASH, or DAC-SASH. Funding, applications, waitlists, and reservation availability vary by utility and program administrator, so confirm current availability with the SGIP administrator before signing a contract.
DAC-SASH supports rooftop solar for qualifying single-family homeowners with an incentive of $3 per CEC-AC watt. The program is designed to make solar available at no cost to eligible households, although project costs, program rules, and funding availability determine whether a particular installation can proceed. The incentive is administered through the program and is not necessarily paid as cash directly to the homeowner.
Applicants generally must own and occupy their primary residence, meet applicable CARE or FERA income criteria, and live in an eligible disadvantaged community or other qualifying area identified by the program. DAC-SASH is a solar program; do not assume that a battery is included. Check current program eligibility and enrollment status with the CPUC or its administrator.
SOMAH provides solar incentives for qualifying affordable multifamily rental housing. Published solar rates can reach $3.50 per AC watt for tenant-serving capacity and $1.19 per AC watt for common-area capacity, with lower rates applying in some circumstances when projects use specified tax credits. Eligible integrated solar-and-storage projects may receive a storage incentive of $1.10 per Wh, subject to program rules and adjustments for other incentives.
Properties generally need at least five rental units and must meet SOMAH’s affordable-housing and tenant-benefit requirements in a participating utility territory. Storage funding is not available everywhere: as of the supplied 2026 status information, storage incentives were paused in PG&E territory, which serves San Jose, and SDG&E territories, while funds were reported available in SCE, Liberty Utilities, and Pacific Power territories. Confirm the current funding status and project eligibility with SOMAH before relying on an incentive.
DAC-GT provides qualifying residential customers a 20% discount on their otherwise applicable electric rate through a clean-energy tariff associated with a shared renewable-energy project. It is a bill discount—not a rooftop-solar or battery installation rebate—and can be relevant to renters or households that cannot install their own system.
Eligibility generally depends on meeting CARE or FERA income requirements and living in a designated disadvantaged community within a participating service area. Enrollment arrangements and availability vary by utility or community choice aggregator, so contact the electricity provider to check whether the program is offered at your address.
GoGreen Home uses credit enhancements to help participating lenders offer financing for eligible home energy improvements, including solar paired with battery storage. Program materials describe a loan-principal ceiling of up to $75,000 for solar-plus-battery projects; this is financing, not a rebate or grant, and borrowers must repay the loan.
Homeowners and renters may qualify for eligible properties and measures when served by a participating utility or community choice aggregator and using an enrolled contractor. Interest rates, fees, approval criteria, and loan terms are set by participating lenders. Confirm that the proposed solar-and-storage project and contractor qualify before applying.
California’s Active Solar Energy System New Construction Exclusion generally prevents the value attributable to a qualifying active solar energy system from increasing the property’s assessed value. This can reduce the property-tax impact of adding qualifying solar equipment, but it is an assessment exclusion rather than an upfront rebate.
The exclusion is scheduled to sunset on January 1, 2027, so it is relevant to qualifying projects in 2026. Treatment can depend on the equipment and how it is installed; the exclusion should not be assumed to cover a standalone battery. Contact the county assessor to confirm how the rules apply to a specific property and project.
California’s Sales and Use Tax Exclusion can reduce or eliminate sales/use tax on qualifying property purchased by an approved participating party or its construction contractor for an approved project. Eligible project categories can include specified alternative-energy, distributed-generation, and energy-storage technologies.
This is a project-approval program, not a blanket sales-tax exemption for a homeowner buying rooftop panels or a battery. Applicants must satisfy the program’s project, party, and approval requirements, so homeowners should not assume a residential purchase qualifies. Consult CAEATFA’s current program materials before including a tax exclusion in project economics.
The Net Billing Tariff, also called the Solar Billing Plan, governs export compensation for most new rooftop solar customers in PG&E, SCE, and SDG&E territories. Customers receive bill credits for electricity sent to the grid, but the credit value varies by when the power is exported and generally is not the old one-for-one retail-rate net-metering credit.
This tariff is a billing policy, not an installation rebate. A battery may allow a household to store solar generation and use it later instead of exporting it, but the financial result depends on the customer’s usage, rate plan, equipment, and export timing. Existing customers may remain on a legacy tariff subject to its rules; other utility territories may have different arrangements.

How to Choose a Solar Installer in San Jose
Verify the license
In California, the contractor or contracting business doing the work must hold an active license from the California Contractors State License Board (CSLB) in a classification authorized for the project. Authorized photovoltaic classifications include C-46 Solar and C-10 Electrical, as well as certain other classifications, including A and, within its scope, B. Check the license status and classification using the CSLB license lookup, and make sure the business named in your contract matches the licensed business. A permit-required project is not eligible for the small-work licensing exemption.
Look for certified installers
Ask whether the people designing and installing your system hold relevant NABCEP certifications, and what the particular credential covers. Certification can be one useful signal of training or demonstrated knowledge; it does not replace the required contractor license or guarantee a particular installation outcome. Also ask about any manufacturer certifications the installer holds for the equipment quoted. Clarify which products and work those certifications cover, and compare the answers across companies rather than treating a logo as a substitute for reviewing the proposal.
Compare quotes the same way
Request written proposals with comparable assumptions. A lower total price may reflect a smaller system, different equipment, or different services. Compare:
- System size in kilowatts (kW) and total price, plus price per watt.
- Panel and inverter brands and models, alongside the estimated annual production in kilowatt-hours (kWh/year) and the assumptions behind it.
- Panel product and performance warranties, inverter warranty, workmanship warranty, and coverage for roof penetrations.
- Who is responsible for permits, inspections, and utility interconnection approval.
- Total cost or monthly payment, and whether a payment escalator applies. For financing or a lease, have the installer explain the payment terms and what is included.
Permits, interconnection and your HOA
The city or county enforcing agency—usually its building department—handles local permit review and inspections, including structural, electrical, and fire-code review. The installer should explain who submits the permit application and arranges inspections. Utility interconnection approval is separate; ask who will submit that application and follow it through. Depending on your location, the utility may be Pacific Gas & Electric (PG&E), Southern California Edison (SCE), Los Angeles Department of Water & Power (LADWP), or Sacramento Municipal Utility District (SMUD). Confirm your utility and the process that applies to it.
California Civil Code §§ 714 and 714.1 limit HOA restrictions: governing-document rules cannot effectively prohibit or restrict a solar energy system, though reasonable restrictions are allowed if they do not significantly increase cost or reduce efficiency. An association also cannot adopt a general policy prohibiting household rooftop solar on an owner’s residence or assigned garage or carport. Ask the installer who coordinates any HOA review.
Red flags
- Pressure to sign the same day. Take time to compare written proposals and terms.
- Unlicensed or out-of-state crews. Out-of-state status alone does not establish a problem, but verify the licensed contracting business responsible for the work and who will be on site.
- Vague production estimates, or a refusal to explain the equipment and assumptions used.
- A large upfront deposit without clear written payment milestones and contract terms.
- A promise of federal homeowner tax credits for a purchase in 2026; homeowner credits ended December 31, 2025.
If you have a construction or home-improvement complaint, the CSLB handles complaints involving licensed and unlicensed contractors and provides a solar-specific complaint form.
Leasing Solar Panels
For San Jose homes served by Pacific Gas & Electric (PG&E), Palmetto offers a solar power purchase agreement (PPA). A PPA charges for the electricity the panels produce at an agreed price per kilowatt-hour; payments can vary by season as production changes. Availability depends on your utility and address.
Unlike paying cash to own a system, a PPA can avoid a large upfront purchase. The system provider owns the equipment and, under the agreement, handles maintenance, so you are not responsible for arranging repairs yourself. Review contract terms and any remaining utility bill when comparing costs.
Leases use a set monthly payment and are available in some California utility areas. Learn more about buying or leasing solar and Palmetto LightReach.
Go solar without the investment
With LightReach, there are no investment costs to recoup, loan payments to manage, or maintenance needs to take on. As soon as your panels are active, your solar savings are too!
Explore LightReach LeasingFrequently Asked Questions
Yes. San Jose homes served by PG&E can receive bill credits for solar electricity sent to the grid. For most new solar interconnection applications submitted since April 15, 2023, PG&E uses California’s Net Billing Tariff, often called NEM 3.0, rather than traditional one-for-one net metering.
Under this tariff, export credits vary by hour and are generally lower than the retail electricity rate. Some customers with complete applications submitted by April 14, 2023 may retain NEM 2.0. Check your utility and specific account rules, since service and credit details can vary.
Yes, owned solar panels may increase a San Jose home’s resale value. Zillow’s study found homes with solar panels sold for about 4.1% more on average. That estimate is not a guarantee or specific to San Jose; value depends on the home, system, and market.
This potential value increase applies to systems the homeowner owns, not leased or third-party-owned (TPO) systems. A leased system may affect resale differently because a buyer may need to assume the remaining agreement.
In San Jose, homeowners can go solar with a LightReach lease for a low fixed monthly payment and no upfront cost. The calculator estimates $65–$119 per month based on home size; a typical medium home is about $88 per month.
Cash purchase is another option: estimates range from $14,860 to $25,233, with a typical system around $19,288. The federal 30% tax credit is no longer available for residential cash purchases following the 2025 federal law change. See the calculator above for pricing details.
Solar leasing means the provider owns the panels; you pay monthly, with no upfront cost. LightReach includes the system, installation, monitoring, maintenance, comprehensive protection, and a 90% production guarantee. A typical 6.67 kW San Jose system is about $88/month, based on 1,440 kWh/kW/year and $0.11/kWh.
Palmetto claims the commercial ITC and passes savings through lower payments; homeowners don’t claim it. Payments are typically below current electricity bills, so savings may begin once panels operate. PG&E bills and contract terms affect total costs.
A typical 6.67 kW home solar system in San Jose can produce about 11,000 kWh of electricity per year, or roughly 30 kWh per day on average. The article’s NREL-based estimate is 11,532 kWh annually for a 7 kW system, which scales to about 11,000 kWh for 6.67 kW.
Production is higher during San Jose’s sunny summer months and lower in winter. A roof’s direction and angle, shade from trees or buildings, and local weather can change a system’s actual output.
There isn’t one best solar installer for every San Jose home. The right fit depends on your roof’s condition and shade, electricity use, PG&E rate plan, system design, installation support, and contract terms.
At Palmetto Solar, we’ve completed 13,826 installations in California since 2020. We bring national experience with a local installation network and offer financing options; compare system estimates, payment terms, warranties, and service details for your home.
San Jose programs include SGIP solar-and-battery rebates, DAC-SASH homeowner aid, SOMAH multifamily incentives, DAC-GT’s 20% bill discount, and GoGreen solar-plus-battery loans. Qualifying solar may receive a property-tax exclusion (scheduled to end Jan. 1, 2027); PG&E customers can earn variable export credits. CAEATFA sales-tax relief is limited to approved projects.
After the 2025 law change, the 30% federal residential credit is unavailable for cash purchases. Palmetto says LightReach claims the commercial ITC and passes savings through as lower monthly payments.
