ConsumerAffairs has heard from thousands of Californians who have already gone through the solar panel installation process. Here’s what Santa Clara residents should look out for when choosing a solar panel installation company. We’ll also touch on overall costs and ways to save with government incentives.

A typical solar panel installation costs anywhere from $8,645 to $24,700 in California. Prices in Santa Clara are comparable, ranging from $8,960 to $25,600.

This doesn’t include an energy storage battery, which sometimes costs as much as the panels: $7,000 to $18,000. A battery lets you store excess energy generated during the day and use it when your panels aren’t producing. It’s worth considering if California’s net metering rates continue to decline or if your area gets frequent blackouts.

System size is the other major solar cost factor. The average Santa Clara household needs a system with a capacity of 8.64 kW (kilowatt) to fully offset their electricity costs. Depending on how much energy you and your family use, you might need a smaller or larger one.

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. A potential downside to leasing is that you won’t be eligible for the federal solar tax credit.
• Free solar panels: 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 panels are generally worth it in California if you like the idea of lowering your monthly utility bills. On average, Santa Clara homeowners with solar panels can avoid $54,486 in total utility costs 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 years to break even (when your savings with solar panels make up for the cost).

The County of Santa Clara has generally solar-friendly policies, including a streamlined permitting process for small residential solar systems, to make installations faster and easier. We suggest using NREL’s PVWatts Calculator to estimate how much electricity a solar panel can produce over a year on your house. Project Sunroof is a reliable online solar savings estimator.

Potential roof problems

As a rule of thumb, if your roof is more than 10 years old, consider fixing it before going solar. Installing solar panels on an old roof might mean you have to remove the panels, replace your roof and then reinstall the panels again. This is an expensive and frustrating process.

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.

• 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).
• Read reviews: Avoid companies with recurring complaints about misleading sales tactics, equipment failures, billing issues and lack of communication.
• 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.
