San Diego Electricity Prices
Electricity in San Diego is among the most expensive in the country — and costs have been rising steadily for years.
SDG&E customers now pay around 31.9 cents per kWh — nearly double the U.S. average of 16.5 cents. Since 2021, California rates have climbed roughly 40%, while national rates rose about 20% over the same period.
Solar panels generate electricity from sunlight, which means homeowners can offset a meaningful portion of what they would otherwise buy from SDG&E. The higher local rates are, the more each kilowatt-hour of solar production is worth to you.
Because electricity rates have historically trended upward, a solar system installed today may provide increasing value over time. Many San Diego homeowners find that locking in their own energy production helps reduce exposure to future rate increases.
Price of Energy: California vs National Average
San Diego Area Utility Providers
San Diego residents are primarily served by San Diego Gas & Electric (SDG&E). As of 2023, SDG&E’s average residential electricity rate was 45.5¢ per kWh — among the highest of any utility in the country.
To put that in perspective, the 2023 national average was 16.0¢ per kWh, and California’s statewide average was 29.50¢ per kWh. SDG&E’s rates are nearly three times the national average — a gap driven by infrastructure costs, wildfire mitigation investments, and California’s regulatory environment.
When electricity costs this much, every kilowatt-hour your solar panels generate is one you don’t have to buy from SDG&E. For San Diego homeowners, that math makes solar worth understanding — even before considering any local incentives.

California Solar Incentives
San Diego homeowners may qualify for several solar incentives in California that can meaningfully reduce the cost of going solar.
State programs like SGIP and DAC-SASH offer rebates for income-qualified households — some covering up to 100% of system costs. These programs are designed to make solar more accessible across California communities.
With solar lease agreements, the third-party owner claims the commercial tax credit and typically passes those savings to homeowners through lower monthly payments.
| Incentive | Type | Description | Source |
|---|---|---|---|
| SGIP – Residential Solar & Storage Equity (RSSE) – AB 209 | Rebate | A state-funded rebate of $3,100/kW for solar and $1,100/kWh for battery storage available to income-qualified California households, potentially covering 100% of system costs. | Learn More |
| DAC-SASH – Disadvantaged Communities Single-Family Solar Homes Program | Rebate | An upfront solar installation rebate of up to $3/watt for income-qualified homeowners in California disadvantaged communities, administered by GRID Alternatives through 2030. | |
| Federal Commercial Solar Investment Tax Credit (ITC-48E) – Third-Party Owned Systems | Tax Credit | Businesses and third-party solar owners (lease/PPA providers) can claim a 30%+ federal Investment Tax Credit for solar projects that begin construction before July 4, 2026, with savings often passed to homeowners through prepaid leases at a ~30% discount. | Learn More |
The Self-Generation Incentive Program (SGIP) Residential Solar and Storage Equity (RSSE) budget is the only active SGIP pathway in 2026. Funded by $280 million in state dollars under AB 209, it offers $3,100 per kW for paired solar and $1,100 per kWh for battery storage — generous enough to cover 100% of system costs for many households. For example, a typical 7 kW solar system paired with a 10 kWh battery could receive up to $21,700 for solar and $11,000 for the battery, totaling $32,700 in incentives.
To qualify, your household income must be at or below 80% of the Area Median Income (AMI), or you must be enrolled in the CARE, FERA, or ESA utility assistance programs. You must also be a residential customer of PG&E, SCE, SDG&E, SoCalGas, or LADWP. Systems must be sized to the home’s actual electricity usage — batteries larger than 15 kWh for single-family homes require justification based on energy consumption.
As of early 2026, the $280 million budget is fully reserved, but new applications are accepted on a waitlist and funded as existing reservations cancel. The best way to apply is through an SGIP-approved installer. All applicants must enroll in a qualified Demand Response program within one year of reserving funds. Check current funding availability at selfgenca.com.
The Disadvantaged Communities – Single-Family Affordable Solar Homes (DAC-SASH) program provides an upfront rebate of up to $3 per watt for solar installations, which can cover $12,000–$15,000 of the cost of a typical 4–5 kW system. The program is funded at $8.5 million annually and remains active through 2030, making it one of the most valuable solar incentives available to qualifying Californians in 2026.
To be eligible, you must: (1) receive electrical service from PG&E, SCE, or SDG&E (2) own and occupy a single-family home as your primary residence; (3) live in a Disadvantaged Community (DAC) as identified by the CalEnviroScreen 4.0 map; and (4) have a total household income within CARE or FERA program limits. You can verify your address using the CalEnviroScreen tool at oehha.ca.gov/calenviroscreen.
The program is administered by GRID Alternatives, a nonprofit solar installer. The rebate covers equipment and installation costs, though out-of-pocket expenses may apply for roof repairs, panel upgrades, or permitting fees. To get started, complete the online eligibility form at gridalternatives.org or call GRID Alternatives toll-free at (866) 921-4696 for a pre-screening conversation.
While the federal residential solar tax credit (25D) has expired for homeowner-purchased systems, the commercial Investment Tax Credit (ITC-48E) remains available for third-party owned solar systems — including those installed under leases and Power Purchase Agreements (PPAs). Solar companies that own and install systems on residential rooftops can claim a base credit of 30% of system costs, with bonus adders of up to 10% each for projects in low-income communities, energy communities, or on Indian land — potentially reaching 40% or more.
For homeowners in San Diego, the most practical benefit comes through prepaid solar leases: because the third-party owner claims the commercial ITC, they can pass the equivalent ~30% savings directly to you as a reduced purchase price at the point of sale. This effectively replicates the financial benefit of the expired residential ITC without requiring you to have any personal tax liability. PPAs offer a similar benefit — you pay nothing upfront and lock in a per-kWh rate below your utility’s current price.
To qualify for the commercial ITC, projects must begin construction before July 4, 2026. Projects that miss this deadline must be placed in service by December 31, 2027 to remain eligible. If you are considering a solar lease or PPA, act promptly to ensure your provider can begin construction in time to capture the credit and pass the savings to you. LightReach is currently the only California PPA provider offering battery storage under the same agreement — an important consideration for SDG&E customers under NEM 3.0.

Leasing Solar Panels
San Diego homeowners served by San Diego Gas & Electric (SDG&E) have access to a Power Purchase Agreement (PPA) through Palmetto’s LightReach program. With a PPA, you don’t pay a fixed monthly amount — instead, you pay a set rate per kilowatt-hour (kWh) for the solar energy your panels produce. That means your bill may be slightly higher in sunny summer months and lower in winter, but your average annual savings are comparable to a lease.
The biggest advantage over a cash purchase? No upfront cost, no maintenance responsibility, and no worrying about system repairs. Palmetto owns the system and handles everything — so you simply pay for the clean energy it generates. With SDG&E rates among the highest in the country at around 45.5¢/kWh, locking in a lower per-kWh solar rate can translate to meaningful savings from day one.
Wondering how a PPA compares to buying outright? Explore the full breakdown of buying vs. leasing solar to find the option that fits your situation. For most San Diego homeowners, a PPA is a straightforward way to go solar with no investment required.
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!

Yes, solar makes strong sense in San Diego. With 266 sunny days per year and SDG&E electricity rates around 45.5¢/kWh — nearly three times the national average — San Diego homeowners can save approximately $100,000 over 25 years with a properly sized system.
Upfront cost doesn’t have to be a barrier either. Palmetto’s LightReach solar lease removes the upfront investment entirely — homeowners can go solar with no money down and start saving from day one, with payments starting as low as $89/month.
San Diego is served by San Diego Gas & Electric (SDG&E), which transitioned to Net Billing (NEM 3) on April 15, 2023. Under NEM 3, excess solar energy exported to the grid earns an hourly credit based on the avoided cost to the grid — which varies by time of day and is generally lower than the retail rate.
Homeowners who submitted a complete interconnection application before April 14, 2023 may be grandfathered on NEM 2.0, provided they haven’t significantly modified their system. For NEM 3 customers, any remaining credits are “trued up” annually at roughly 3–5¢/kWh. NEM 3 customers can also select or change their True-Up month by contacting SDG&E.
Yes, solar panels can increase your home value in San Diego. According to a Zillow study, homes with solar panels sell for about 4.1% more than comparable homes without them. In San Diego’s competitive real estate market, that could mean tens of thousands of dollars in added value.
This benefit applies specifically to owned solar systems. If you lease your panels, the value-add is less straightforward, since the system is owned by a third party. Homeowners who purchase their system outright tend to see the greatest impact on resale value.
With Palmetto’s LightReach lease, San Diego homeowners can go solar for as low as $89/month with no upfront cost. Palmetto owns the system, handles all maintenance, and passes savings from the commercial tax credit through to you via lower monthly payments.
For a cash purchase, a typical San Diego home requires a 6.72 kW system priced around $19,414 (approximately $2.89/watt). Note that the federal 30% residential tax credit is no longer available following the Big Beautiful Bill. Use the calculator above for a personalized estimate based on your home size.
For most San Diego homeowners, solar is worth it financially — especially given SDG&E’s rates near 45.5¢/kWh, among the highest in the country. A typical system can save around $100,000 over 25 years.
With Palmetto’s LightReach lease, there’s no upfront investment required. Monthly payments start as low as $89/month — often less than your current electricity bill — meaning many homeowners begin saving from day one.
