Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Putting solar panels on your roof could lower your electricity payments while benefiting the planet by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.
Hiring a licensed solar installer is critical. This help guarantee that the work is done correctly using current best installation practices. There are five distinct classifications of solar contracting licenses in California: boilers, PV electrical, HVAC, thermal, and pool heating. To earn a license, an installer must complete a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, and pass written exams.
Check review sites like the Better Business Bureau (BBB), Google Reviews, and TrustPilot to see customer feedback about local solar companies. Detailed reviews can help you assess a company's dependability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.
Get free, detailed quotes from 3–5 solar companies. The quotes should list all costs and identify the exact solar parts included. Comparing several quotes can help you find the option that best fits your budget.
Quality solar installations should have strong workmanship and performance warranties. A workmanship warranty addresses any installation defects (such as cracks in the panels, poor wiring, or poor alignment), while a performance warranty ensures a certain level of energy production. Strong warranties demonstrate a company's confidence in its work.
Solar energy can help decrease your electricity costs in the long run. When considering solar panel's cost and value, be sure to consider these considerations.
Napa homeowners typically spend about $7,422 on home solar systems after federal tax refunds. Solar arrays in Napa cost roughly $3,470 per kilowatt, with an average size of 3.1 kilowatts. A personalized estimate from a local solar provider will include costs for labor, preliminary work, and permit fees, and will account for your system's size, panel type, and capacity. Some homeowners prefer to lease their solar panels to reduce upfront costs.

Generally speaking, a solar photovoltaic (PV) system can be used to power any household system or appliance that uses electricity. In the simplest case, you can use a solar water heater.
With home solar PV, you can recoup the cost of the system over time, lower your home's carbon footprint, and gain additional energy independence.
It depends on your home's location and what type of panels you're installing. With the winter months in California being very mild, you have significant leeway to install your panels, though they won't reach peak performance until summer arrives.
Yes, you can use home solar energy alongside conventional power sources. In most parts of the country, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings of solar energy without having to completely switch over.
Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Napa, the average amount someone can save is $1,053 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system when your payback period is done.
Net metering is a power purchasing policy that allows solar energy system owners to be compensated for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.
Some frequently-used types of home solar panels in Napa include monocrystalline, thin-film and polycrystalline. Monocrystalline panels are balanced and efficient, while thin-film and polycrystalline panels pair good performance with greater upfront value. Ask your local provider about which solar panels they work with.
