Benefits of Solar Energy

Solar energy offers multiple advantages. Here are some highlights.

  • Better energy independence: Adding a solar battery storage system lets you have dependable energy during grid outages and storms.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, reducing your regular electricity costs. Going off-grid can eliminate your bills completely. Plus, a significant number of states have adopted net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Reduced carbon footprint: Using solar is a surefire way to lower your carbon footprint and home fossil fuel dependency.

How To Choose the Best Solar Company in Westminster

The purchase price and performance of solar panels often depend on which company installed them. Here are some key items to bear in mind while shopping for a solar provider.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar pool heaters, water heaters, HVAC, boilers, and photovoltaic (PV) systems. Contractors must complete a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn a license. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar industry's most reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Westminster

The kind of solar panels you purchase decides how much power you can generate. Monocrystalline panels and high-quality and give you the best performance but cost more upfront. Polycrystalline panels work with a tried-and-true mechanism and cost less, but produce less power. Thin-film panels aren't recommended for large residential installations, but they are ideal for small projects like converting RVs and sheds.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total installation cost, but they can boost your solar system's performance. Not every solar company includes these extras, so look for a contractor that installs them if it's crucial for you.

Generally speaking, it costs about $17,350 for a five-kilowatt solar array in Westminster. This table displays more specific costs for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,235
Solar Polycrystalline$963
Thin-Film$563
Solar Battery$790
Solar Home EV Charger$2,964

Financing Solar Energy in Westminster

There are various ways to pay for a solar energy system, and the right one will lower your costs. A few of the most common options include leases, power purchase agreements (PPAs), loans, and cash payments. Though it involves a large up-front payment, cash is the most cost-effective choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the runner-up option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases allow you to rent your panels for a set monthly rate, while PPAs let you pay only for the energy you use, similar to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each provider you're vetting about the payment options it offers. A consultant can help you determine the optimal option for your financial situation.

The table below lists the average payback periods for different capacities of solar systems in Westminster.

The IRS allows you to claim a 26% federal tax credit for solar panels on your new solar panels, so long as you purchase it before 2032. Local governments and utilities might also offer their own rebates, financing programs, and incentives that could save you more money.

Solar System CapacityEstimated Payback period
1 kW1.4 years
2 kW2.7 years
5 kW6.8 years
10 kW13.7 years
