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 helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.
Verify that your solar installer is properly licensed. This ensures that the work is done correctly using the most up-to-date installation methods. There are five different 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 consumer review platforms like the Better Business Bureau (BBB), TrustPilot, and Google Reviews to see feedback from past customers about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with installers that have very few reviews or mostly negative ones.
Get free, detailed quotes from 3–5 solar companies. A quote should describe all costs and identify the exact solar parts included. Looking at several quotes can help you find the most cost-effective option.
High-quality solar installations should have robust workmanship and performance guarantees. The workmanship guarantee covers any installation issues like poor wiring, cracks in the panels, or poor alignment. The output warranty guarantees an energy generation baseline. Strong warranties reflect a solar provider's confidence in its installations.
Solar energy can help lower your energy expenses over time. Be sure to consider these aspects when determining the cost and value of solar panels.
In Westminster, solar panels cost an average of $3,470 per kilowatt, with an average system size of 2.9 kilowatts. The typical Westminster homeowner spends $7,006 on their solar array after federal tax refunds. An estimate from a local provider will factor in additional information reflecting your desired system's panel type, required preliminary work, capacity, and size. In some cases, homeowners may prefer leasing solar panels to reduce upfront costs.

Generally speaking, a solar photovoltaic (PV) array can be used to power any household system or appliance that uses electricity. In the simplest case, you can use a solar water heating system.
There are a number of advantages of home solar energy. You can qualify for tax benefits, raise your property values, and save money. With the right storage equipment, solar panels can also provide you with further energy independence and offer some protection from power outages.
It depends on your location and the kind of panels you plan to use. With the winter months in California being very mild, you have a lengthy window to install your panels, though they won't reach peak performance until summer arrives.
Yes, it's possible to use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, meaning that you can reap the environmental benefits and savings that come from using solar energy without having to completely switch over.
Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Westminster amount to $751.
Your recommended maintenance will vary based on the type of solar panels you have. With any system, you should clean and inspect each panel every three months. Your solar installer might offer comprehensive plans where they'll do the maintenance on your behalf.
The answer will depend on your specific needs and goals. Generally, monocrystalline solar panels are the most efficient for Westminster homes. However, if lowering cost is your top priority, then you may want to consider polycrystalline or thin-film solar panels. When you're choosing a contractor, make sure to ask about the brand names and models of solar panels a contractor offers and the benefits and drawbacks of each.
