Benefits of Solar Energy

Solar energy provides multiple advantages that will enhance your home for years to come.

  • Reduced carbon footprint: Embracing solar is a surefire way to minimize your carbon footprint and home fossil fuel dependency.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, reducing your regular electricity costs. You can eliminate your bills completely if you go off-grid. 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.
  • Better energy independence: Solar panel systems with energy storage systems operate through power outages and emergencies, and you won't have to rely on the electrical grid for your safety and well-being.

How To Choose the Best Solar Company in Fairfield

Choosing a company is the first step toward a well-oiled and cost-efficient solar system. Make your choice based on the following crucial aspects.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar photovoltaic (PV) systems, water heaters, pool heaters, boilers, and HVAC. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to secure a license. You should also visit a company's website to learn about its private credentials. Two of the most respected are the Solar Heating Installer and PV Installation Professional 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 solar panels' type will impact how much power you can produce. Monocrystalline panels are among the highest quality and perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. 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 raise your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not all solar companies offer these extras, so look for a contractor that installs them if it's a priority for you.

A majority of Fairfield homeowners opt for solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $17,350 to install, considering both parts and installation. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,280
Solar Polycrystalline$998
Thin-Film$584
Solar Battery$819
Solar Home EV Charger$3,071

Financing Solar Energy in Fairfield

Solar installers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar loans, solar leases, power purchase agreements (PPAs) and cash payments. Most solar experts recommend a cash payment or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Much like a car or home loan, you'll pay a set monthly rate with as little as $0 down. Solar leases allow you to pay a monthly rate to rent your panels, while a power purchase agreement lets you pay a variable rate based on only the energy you use. We generally advise against these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. We recommend working with a provider that offers multiple financing options. Talk to each salesperson about what's available, and acquire more than one estimate for the best odds of keeping within your budget.

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

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