A California appeals court recently upheld the state’s net metering 3.0 policy, confirming that the California Public Utilities Commission (CPUC) has the legal authority to reduce the payments homeowners receive for sharing solar energy. On March 9, 2026, the court ruled that the state was within its rights to lower these reimbursements by roughly 75 to 80 percent. While utility companies believe this change makes the energy grid fairer for everyone, solar advocates and environmental groups worry the decision will continue to hurt the growth of clean energy in California.
The Big Change in Solar Payments
For many years, California was a leader in rooftop solar because of a policy called net energy metering. Under the older rules, known as NEM 2.0, homeowners got paid a “retail rate” for the extra electricity they sent back to the power grid. If the utility company charged 30 cents for a kilowatt-hour of power, the homeowner received 30 cents in credit. This made solar panels a very good investment.
In April 2023, the state switched to NEM 3.0, which is also called the Net Billing Tariff. This new system changed how the value of solar energy is calculated. Instead of the retail rate, homeowners now get paid based on “avoided costs.” This means the utility only pays what it would have spent to buy that energy from another source. As a result, the payment for excess power dropped from around 30 cents per kilowatt-hour to just 8 cents in many areas.
The Court’s Final Word
The legal fight over this policy has been long. Groups like the Environmental Working Group and the Center for Biological Diversity sued the CPUC, arguing that the lower rates violated state laws meant to encourage solar growth. The case even went to the California Supreme Court, which asked the appeals court to look at the facts again with “fresh eyes.”
However, the appeals court ultimately decided that the CPUC balanced its goals correctly. In the official court opinion, the judges wrote, “Applying the applicable deferential standard of review, we conclude the successor tariff adequately serves the various, albeit sometimes inconsistent, objectives of the law and thus affirm.” Essentially, the court believes the commission has the power to decide how much solar power is worth.
Terrie Prosper, a spokesperson for the CPUC, said the ruling helps “ensure that rooftop solar programs remain fair, sustainable, and aligned with California’s clean energy goals.”
Impact on the Solar Industry
The shift to NEM 3.0 has already had a large effect on the solar market. Since the new rules started, the industry has seen a massive decline in new projects. According to data from the California Solar and Storage Association, residential solar sales dropped between 77 and 85 percent shortly after the policy took effect.
This slowdown has also led to job losses. Industry reports show that over 17,000 solar jobs were lost in California by the end of 2023. Advocates argue that the high cost of electricity in the state makes solar more important than ever, but the new rules make it harder for regular families to afford the initial cost.
Roger Lin, an attorney with the Environmental Working Group, expressed disappointment in the ruling. He noted that the decision sets the state back in its efforts to fight climate change. Critics of the policy also point out that California’s electricity prices are nearly 0.50 per kilowatt-hour, which is much higher than the national average of 0.17 per kilowatt-hour.
The Debate Over Fairness
The main reason the CPUC and utility companies pushed for NEM 3.0 was to fix what they call a “cost shift.” They argue that when solar owners pay very low monthly bills, they aren’t paying their fair share to maintain the wires, poles, and equipment that make up the power grid. They claim this forces people without solar panels, including many lower-income families, to pay more to cover those costs.
On the other side, solar supporters say that rooftop solar actually helps the grid. They argue that local energy reduces the need for expensive new power plants and long-distance transmission lines. By ignoring these “societal benefits,” advocates say the state is missing the bigger picture.
Moving Toward Batteries
Because the payments for sending power to the grid are now so low, the “solar-only” business model is changing. Many experts believe that the best way for homeowners to save money now is to pair their solar panels with a battery storage system.
With a battery, a homeowner can store the extra energy they produce during the day and use it at night instead of selling it back to the utility for a low price. Data shows that battery adoption is rising. Before NEM 3.0, only about 11 percent of new solar systems included a battery. By 2024, that number jumped to over 50 percent.
While batteries help homeowners save more, they also add thousands of dollars to the cost of a home energy system. This means the total time it takes for a system to pay for itself is now around 7 to 9 years, compared to the 4 to 5 years seen under the old rules.
The appeals court ruling seems to close a major chapter in the legal battle over California solar. While the policy remains in place, the industry is adjusting to a new reality. The focus has moved from simply installing panels to managing energy through smart technology and storage.
Even with the lower payments, solar energy still offers long-term savings for many Californians. As energy prices continue to rise, the desire for independence from the traditional power grid remains strong. However, the days of high reimbursements for excess power are officially over.
