For homeowners in Lakeside, the combination of strong inland sun and high San Diego Gas & Electric (SDG&E) rates makes solar appealing. However, the rules for solar compensation have changed. In 2026, the value of a solar system depends heavily on how you use the energy you produce, not just how much you generate. With electricity rates around $0.323/kWh, the key is to avoid buying expensive power from the grid, especially during peak evening hours.

2026 Solar & Battery Costs in Lakeside
Here are modeled cost estimates for a typical home in the Lakeside area. These figures reflect installation in 2026 and do not include the expired federal tax credit.
- Solar Panels Only (7.0 kW): The estimated gross cost is around $17,850. This system is sized to cover a typical local electricity bill.
- Solar Panels + Battery (7.0 kW system with 10 kWh battery): The estimated combined gross cost is $32,850. The battery adds significant capability to store and use your own solar power.
An owned solar system can also be a valuable long-term feature, potentially supporting your home's resale appeal.
Incentives & Tax Credits
California Solar Incentives in 2026
With the primary federal residential tax credit no longer available for systems installed in 2026, the financial benefits of solar in California now center on state-level policies and direct bill reduction.
- Property Tax Exclusion: California law prevents your property taxes from increasing due to the added value of a solar system. For systems installed through mid-2026, this is a significant benefit that saves you money every year.
- High Rate Avoidance: The most powerful financial incentive is avoiding SDG&E's high electricity rates. Every kilowatt-hour of solar energy you use at home is a kilowatt-hour you don't have to buy from the utility at retail prices.

Net Billing (low export)

Understanding Export Rates with SDG&E
Lakeside falls under California's Net Billing Tariff (NBT), often called NEM 3.0. This policy fundamentally changes how you are compensated for extra solar energy.
Instead of getting a one-to-one credit, any solar power you send to the grid is bought by SDG&E at a much lower rate (modeled here at around $0.11/kWh). This is significantly less than the $0.32/kWh or more you pay to buy electricity. This is why storing your solar energy in a battery for your own use is now the recommended strategy for achieving the best financial outcome.
Projected Savings
Modeled Annual Savings: Why a Battery Makes a Difference
Under current SDG&E rules, maximizing the amount of solar energy you use at home (self-consumption) is the best way to save money. Storing solar power in a battery for evening use dramatically increases your savings.
- With a Solar + Battery system, a Lakeside homeowner could see an estimated $3,308 in electricity bill savings in the first year. The system is projected to pay for itself in about 8.2 years.
- With a Solar Only system, the estimated first-year savings are lower at $2,216, with a payback period of around 7.4 years. While the initial cost is less, you save over $1,000 less each year because you are forced to sell your valuable midday solar energy to SDG&E for a low price.
These savings can become more impactful over time if grid electricity rates continue to rise, making your self-generated power even more valuable in the future.
