Benefits of Solar Energy

Solar energy comes with multiple advantages. Let's look at a few of them.

  • Reduced carbon footprint: Using solar is a surefire way to minimize your carbon footprint and home fossil fuel dependency.
  • Lower energy bills: Generating some or all of your own energy will cut power costs long-term. Plus, some states provide net metering programs that allow you to sell your extra energy back to the grid, generating additional credits toward your energy bill.
  • Better energy independence: Solar energy can keep your home functioning through blackouts and emergencies, giving you additional security. You can use your solar energy anytime with an optional battery storage system.

What Solar Incentives Are Available to Fairfield Homeowners?

Governments and power companies often incentivize homeowners for adopting solar. Here are some of the tax credits, rebates, or other programs you could qualify for.

Incentive Amount:

100% of system value; 75% of system value exemption for dual-use equipment

How To Choose the Best Solar Company in Fairfield

Choosing a company is the first step toward an effective and cost-efficient solar array. Make your choice based on the following essential elements.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar HVAC, water heaters, boilers, pool heaters, 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. You should also visit a company's website to learn about its private certifications. Two of the most prestigious are the PV Installation Professional and Solar Heating Installer certificates, awarded by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Fairfield

Your photovoltaic panels' type will influence how much power you can produce. Monocrystalline panels are among the highest quality and cost the most but perform the best. Polycrystalline panels generate less, but they're a great traditional option for low budgets. Thin-film panels have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

Additional system add-ons, such as electric vehicle (EV) chargers and battery storage, will increase your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar provider includes these optional components, so look for a contractor that installs them if it's essential for you.

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

Solar Panel CostAverage Cost
Solar Monocrystalline$1,279.64
Solar Polycrystalline$998.12
Thin-Film$583.52
Solar Battery$818.97
Solar Home EV Charger$3,071.14

Financing Solar Energy in Fairfield

Choosing the best financing option will affect your overall solar system cost and expected savings. Common payment options include power purchase agreements, loans, cash payments, and leases. Though it involves a large up-front payment, cash is the most cost-effective choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the second most effective option. As with a home or auto loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for money-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases involve paying a set monthly rate to use rooftop panels. A PPA (Power Purchase Agreement) enables you to pay a monthly rate based only on the energy you use, similar to an electric bill. We usually don’t recommend these two choices because you won't own the system and cannot use solar incentives. Look for contractors that offer two or more payment plans to find the right fit for your wallet.

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

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own rebates and financing plans that could reduce your total cost even more.

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