With Southern California Edison (SCE) electricity rates among the highest in the nation, many Hawthorne homeowners are looking for ways to reduce their monthly bills. Rooftop solar is a powerful tool, but the rules have changed. In 2026, the value of solar is tied directly to how much of the energy you can use yourself, rather than exporting it to the grid. This shift makes understanding your potential savings and the role of battery storage essential.

Estimated 2026 Solar Installation Costs in Hawthorne
The total cost for a solar installation is based on the system's size and whether you include a battery. Here are the modeled costs for a typical home in the area:
- 7.9 kW Solar-Only System: The estimated gross cost is $20,145. This size is designed to offset the average local electricity bill.
- 7.9 kW Solar System + 10 kWh Battery: The combined system has an estimated gross cost of $35,145. The battery adds to the initial investment but delivers higher annual savings, making the economics very strong.
These are baseline estimates. Your final cost will depend on the specific equipment, installer, and any unique characteristics of your roof.
Incentives & Tax Credits
Key California Solar Benefits in 2026
Even without the once-standard 30% federal tax credit for homeowners, California provides a supportive environment for going solar. The main financial benefits come from state-level policies and the high cost of grid electricity.
- Property Tax Exclusion: When you install a solar system, its value is excluded from your property tax assessment. This means your property taxes won't go up, even though you've added a valuable asset to your home.
- High Bill Offset: The most significant incentive is the direct savings you get by not having to buy expensive electricity from SCE. Every kWh you generate and use at home is a kWh you don't have to buy at a premium.
In a competitive real estate market like Los Angeles County, an owned solar system can also be a significant asset, enhancing your home's appeal to future buyers.

Net Billing (low export)

How SCE's Net Billing Tariff Affects Your Savings
Hawthorne falls under California's Net Billing Tariff (NBT), which has replaced the old 1-for-1 net metering system. Under NBT, any excess solar energy you export to the grid is credited at a low wholesale rate (modeled here at $0.11/kWh). This is significantly less than the retail rate you pay to buy electricity from SCE.
This structure creates a clear financial incentive to use your solar power on-site. A home battery is the most effective way to do this. It stores the excess solar power your panels generate during the sunny afternoon so you can use it to power your home in the evening, maximizing your savings and minimizing what you sell back to the grid for a low price.
Projected Savings
Potential Solar Savings in Hawthorne
Generating your own electricity allows you to avoid buying it from SCE at their high retail rate of over $0.32 per kWh. The more solar power you use at home, the more you save. Long-term utility inflation can also improve the value of your system over time; if grid power gets more expensive, your self-generated power becomes even more valuable.
- A typical 7.9 kW solar-only system in Hawthorne is estimated to save $2,438 per year, leading to a payback period of approximately 7.6 years.
- By adding a 10 kWh battery to that system, the estimated annual savings jump to $3,657. The payback period is similar at 8.0 years, but the total long-term savings are substantially higher, making it a financially compelling upgrade.
