A battery lets you store extra solar energy to use at night or during outages. This is a valuable feature in places like Stockton that experience frequent blackouts. It can also help offset declining net metering credits in California.

The cost of a solar battery is often worth it. One solar customer in Stockton, Rebecca, told us she likes how her solar panels keep her AC running in the summer and she’s happy with the results overall. However, she regrets not adding a battery for backup power.

In our experience, the best solar companies in California have a few things in common: lots of experience, reliable equipment and transparent contracts. Here are some hiring tips.

1. Check certifications

California requires solar contractors to hold a C-46 licensing classification, which you can check through the Contractors State License Board. We also recommend choosing an installer certified through the North American Board of Certified Energy Practitioners (NABCEP).

Some solar scammers in Stockton may falsely claim to be affiliated with a San Joaquin County or California government agency.

2. Read reviews

Look at solar company reviews on platforms like ConsumerAffairs, Better Business Bureau and solar-specific forums to see real customer experiences. Watch out for these red flags:

• Equipment failures that aren’t resolved quickly
• Misleading sales tactics about costs or savings
• Billing and contract issues

Local experience matters, too. It makes it easier to navigate regulations, permits and available financial incentives.

3. Ask questions

Do you need a solar storage battery, electric vehicle (EV) charger or critter guards? How does this affect overall pricing? What if your system needs maintenance? If you don’t understand something about the payment terms, warranty or ongoing services, ask for clarification.

How can I pay for solar panels?

Getting solar panels is like buying a car. Most people pay cash, finance or lease. Similar to leasing, a power purchase agreement (PPA) lets you get the benefits of solar without actually owning the equipment.

• Solar loans work like any other type of loan. They have relatively low fixed interest rates. Once you pay it off, you own your system outright.
• Solar leases are a good option if you have limited savings and don’t want to take on debt. 
• Free solar panels: For eligible homeowners, the Disadvantaged Communities Single-family Solar Homes (DAC-SASH) program, run by GRID Alternatives, offers no-cost rooftop solar installations for income-qualified homeowners in disadvantaged communities.

Solar incentives in Stockton

The federal solar tax credit expired at the end of 2025.

Residents can also take advantage of statewide solar incentives in California, including Self-Generation Incentive Program (SGIP) rebates for homeowners who install battery storage systems with their solar panels.

Additionally, the California Energy Commission (CEC) offers various incentives and rebates, including incentives for solar water heating systems and energy efficiency upgrades, which can be combined with solar installations to maximize overall savings.

Solar panels are generally worth it in California if you like the idea of lowering your monthly utility bills. On average, Stockton homeowners with solar panels can avoid $150,779 in total utility costs over 25 years.

Homeowners with solar panels typically save $20,000 to $90,000 over 25 years.

For a lot of homeowners, the main drawback is the high upfront cost of purchasing and installing the panels and equipment. Assuming an upfront purchase, it takes about 5.63 years to break even (when your savings with solar panels make up for the cost).

Think of going solar in terms of your monthly costs. Given rising energy costs, financing solar panels makes sense as long as your monthly loan payment is less than what you would be paying the utility company anyway.

Potential roof problems

If your roof is more than 10 years old, get it inspected before going solar. Installing panels on an aging roof could mean removing them later, replacing the roof and reinstalling. This is an expensive hassle.
