Benefits of Solar Energy

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

  • Better energy independence: Solar panel systems can keep your home running through emergencies and blackouts. You can use your solar energy anytime with optional battery backup.
  • Lower utility costs: Sourcing some or all of your own energy will spend less on electricity long-term. Plus, some states provide net metering programs that enable you to sell your extra energy back to the grid, generating additional credits toward your energy bill.
  • Reduced carbon footprint: Solar is a highly abundant clean energy source, meaning you can reduce or eliminate your home's dependence on "traditional" sources.

What Solar Incentives Are Available to Napa Homeowners?

California agencies and electric companies offer a number of solar incentives to help cut your solar system costs. Here is a breakdown of applicable solar programs where you live.

Incentive Amount:

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

How To Choose the Best Solar Company in Napa

The more thorough your company investigation is, the better your solar system will ultimately operate. Make your choice based on the following important considerations.

Licensing and Training

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

Cost of Solar Panels in Napa

Your solar modules' model will impact how much electricity 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.

You can also add electric car (EV) chargers and battery backup systems. These will increase your total installation cost, but they can enhance your solar system's efficiency. Not all solar providers offer these add-ons, so look for a contractor that sells them if it's essential for you.

A majority of Napa homeowners select solar systems rated for five kilowatts (kW) of electrical capacity. These systems cost about $17,350 to set up, considering both parts and installation. You can see more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,251.43
Solar Polycrystalline$976.11
Thin-Film$570.65
Solar Battery$800.91
Solar Home EV Charger$3,003.43

Financing Solar Energy in Napa

Solar contractors offer multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are solar leases, solar loans, power purchase agreements (PPAs) and cash payments. Most solar experts recommend a cash payment or using a solar loan. Cash payments require 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. Similar to a car or home loan, you'll pay a set monthly rate with potentially $0 down. Solar leases allow you to pay a monthly fee to rent your panels, while a power purchase agreement lets you pay a fluctuating rate based on only the energy you use. We generally advise against these options since you won't own your system and are disqualified from solar incentives, but they might be suitable in certain circumstances. We suggest working with a provider that offers multiple financing options. Speak with each salesperson about what's available, and acquire more than one estimate for the best odds of staying within your financial plan.

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

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 financing plans and rebates that could reduce your total cost even more.

Solar System CapacityEstimated Payback period
1 kW1.4 years
2 kW2.7 years

10 kW13.7 years
