Solar Owners, Take Note: Why Your Bill Might Still Be High and How to Fight Back

When Sarah installed 32 solar panels on her home, she expected her electric bill to plummet. For a while it did — last year her May bill was just $23. But this year, her bill jumped to $427 even though her energy use and the panels themselves hadn’t changed. What happened?

The answer lies in a mix of policy changes, sales misrepresentations and billing practices that can undermine the savings solar customers expect. If you’ve noticed your own bills creeping higher despite having panels on your roof, you’re not imagining things. Below we unpack the three biggest issues hurting solar customers and offer an actionable plan to protect your investment.

1. How NEM 3.0 Changed the Game

In April 2023 California introduced NEM 3.0, a solar billing policy that drastically reduces the value of the electricity you send back to the grid. Under the previous rules, homeowners received full retail credit for each kilowatt‑hour they exported. Under NEM 3.0, export credits are worth only about 25 % of the retail rate. That means you may sell excess power for around 8 cents per kWh and buy it back in the evening for 30–45 cents. For many systems, the reduction translates into roughly 50% less bill savings.

Because NEM 3.0 compensates daytime exports at a fraction of what you pay for power at night, the best strategy for solar owners is to use more of your solar energy on-site or store it in a battery. Storing or shifting your production reduces the amount of power you sell at a discount and the amount you buy back at premium evening rates. Solar analysts estimate that pairing a battery with a solar array can cut leftover bills by up to 80 % under NEM 3.0.

Tip: If you installed your system before the NEM 3.0 adoption date, check whether you are still eligible for NEM 2.0 — grandfathered customers can maintain higher credits by filing the appropriate paperwork with the California Public Utilities Commission.

2. Watch Out for Installer Misrepresentation

Policy isn’t the only reason bills stay stubbornly high. Some systems underperform because they’re poorly designed or mis-sold. For instance, shading or roof orientation can dramatically reduce production. In one case, a homeowner’s solar proposal guaranteed a bill close to zero, yet the installer ignored obvious shading from nearby trees. Worse, the contract specified premium panels but the installer substituted lower‑wattage modules to maximise tax credit value. The result? A larger monthly bill after going solar and an undersized system that never met expectations.

To protect yourself:

• Request a shade analysis before you sign. Reputable installers will provide one.

• Verify equipment models and wattages against the contract. Don’t let anyone switch equipment without your approval.

• Get multiple quotes from licensed, well‑reviewed companies.

3. Understand Your Smart Meter and Rate Plan

Utilities install smart meters to measure power flowing to and from your home. These meters can be configured in various ways. In California many net‑metered customers are on time‑of‑use (TOU) billing, where daytime credits are worth far less than evening charges. If your meter is set to “net consumption” for TOU, you may receive off‑peak credit for your solar exports but pay peak rates when you need power after sunset.

Key steps:

1. Check your rate plan. Ask your utility which TOU options are available.

2. Request a different meter configuration if one exists that better values your daytime exports (e.g., “bidirectional net metering”).

3. Monitor your billing statement to ensure the plan and meter settings align with what you requested.

How to Fight Back and Save

If you’re feeling frustrated with a higher‑than‑expected solar bill, here’s a practical action plan:

1. Verify your grandfathered status. If you installed before NEM 3.0 took effect, you may still qualify for NEM 2.0. Contact the CPUC or your installer for help.

2. Audit your system’s performance. Use your monitoring software to check output. If production is lower than expected, clean your panels and contact your installer to check for shading or equipment issues.

3. Check your installer’s paperwork. If you suspect misrepresentation or equipment swaps, file a complaint with your state’s contractor licensing board.

4. Consider adding storage. Batteries let you capture surplus solar power and use it when rates are highest, helping you avoid selling power at low export rates.

5. Review your rate plan and meter settings with your utility to ensure you’re not stuck in a plan that undercuts your solar investment.

Conclusion and Next Steps

Solar power remains one of the best ways to hedge against rising utility rates, but changing policies and bad actors mean you need to stay informed. By understanding how NEM 3.0 works, holding installers accountable and optimizing your rate plan, you can keep your solar savings on track.
