Analyst Note: The "4kW Benchmark"

The analysis below uses a standardized 4kW system to provide a fair baseline comparison across cities. However, the average electric bill in Covina is $243.0.

⚠️ Most homes here will need a larger system (8kW–12kW) to reach 100% offset. Use the calculator below for your exact numbers.

For homeowners in Covina, the question in 2026 isn't just about getting solar panels—it's about getting the *right* solar system. Southern California Edison's (SCE) current rate structure, known as Net Billing (or NEM 3.0), drastically changed the math for solar savings. Without a battery, the value of going solar is severely limited. But with one, you can take back control from the utility and achieve real energy independence.

Benchmark Cost Analysis

The Real Cost of Going Solar in Covina in 2026

Given the reality of NEM 3.0, the recommended path for any Covina homeowner is a solar-plus-battery system. While a solar-only installation seems cheaper at around $8,050 after the tax credit, it's an incomplete solution that leaves significant savings on the table.

The realistic, high-value investment is a combined system. The gross cost is around $23,500. After claiming the 30% Federal Tax Credit, your final net cost is approximately $16,450. This investment achieves true energy freedom from SCE's fluctuating rates and has an estimated payback period of under 10 years thanks to the higher annual savings.

Incentives & Tax Credits

Federal & State Solar Incentives

The single best incentive is the 30% federal solar tax credit, which allows you to deduct 30% of the total system cost (including the battery) from your federal taxes. On top of that, California law provides a 100% property tax exclusion for residential solar systems. This means your property taxes won't increase, even though the solar system adds significant value to your home.

Battery Priority

Critical 🔋

Why a Battery is Essential Under SCE's NEM 3.0

Under the old rules, SCE gave you a credit nearly equal to the retail price for every excess kilowatt-hour your panels sent to the grid. Under NEM 3.0, that's over. Now, the credit you get is slashed by about 75%. Sending power to the grid during the day might earn you just 5-8¢/kWh.

This is where a battery changes everything. Instead of selling your valuable solar energy to SCE for pennies, you store it in your battery. Then, during the evening when electricity rates skyrocket to over 40¢/kWh on Time-of-Use plans, you power your home from your battery for free. This 'self-consumption' strategy is the key to maximizing savings in the modern solar era.

Projected Savings

Annual Savings: How a Battery More Than Pays for Itself

A Covina household with a $243 average monthly SCE bill sees a massive difference in savings depending on their system. A solar-only setup might only save about $1,188 per year because of the poor export rates. However, by adding a battery and using your stored solar power during expensive peak hours, those annual savings jump to $1,676 or more. You avoid buying SCE's most expensive power, which makes the battery a critical financial tool, not just a backup device.

Local Questions Answered

What happens if I have solar but my power still goes out?
If you have a standard solar-only system, it will shut down during a grid outage for safety. However, with a solar and battery system, your home can disconnect from the grid and run on the stored battery power, keeping your lights and appliances on.
How does SCE's Time-of-Use (TOU) plan work with a battery?
A solar battery is perfect for beating TOU rates. Your panels charge the battery during the day when solar is abundant and rates are lower ('off-peak'). Then, during the 4-9 pm 'on-peak' window when SCE's rates are highest, your home draws power from the battery instead of the grid, maximizing your savings.
Is the payback period for solar longer now with NEM 3.0?
Yes, compared to the old NEM 2.0 system, the payback period is slightly longer. However, for a properly sized solar-plus-battery system in Covina, the payback is still strong at around 9-10 years, after which you'll enjoy decades of nearly free electricity.
