How To Choose the Best Solar Company in Danville

The more comprehensive your provider search is, the better your solar installation will ultimately work. Consider all of these criteria in your company search.

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, boilers, HVAC, and photovoltaic (PV) systems. Contractors must take a highly comprehensive educational series, gain four years of experience as an apprentice or journeyman, 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 respected are the Solar Heating Installer and PV Installation Professional certificates, backed 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 Danville

The type of solar panels you select decides how much electricity you can produce. Monocrystalline panels 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.

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

You can plan to spend about $17,350 on average for a five-kilowatt solar energy system in Danville. Use the table in this section to get an idea of the amount Danville solar companies might quote for your specific system.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,322
Solar Polycrystalline$1,031
Thin-Film$603
Solar Battery$846
Solar Home EV Charger$3,172

Financing Solar Energy in Danville

There are a plethora of ways to pay for a new solar system, and the right one will lower your costs. A few of the most common options include cash payments, loans, leases, and power purchase agreements (PPAs). We advise paying with cash or securing a solar loan for the best return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also have full ownership of your system and can apply for solar incentives to cut your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in installments while still enjoying energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases allow you to use 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 don't grant you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Look for installers that offer two or more payment plans to find the right fit for your budget.

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

A 26% federal tax credit applies to recently-purchased solar equipment purchased through 2032. Additional incentives may be available through local governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in Danville

How much money could I save by going solar in Danville?

On average, Danville homeowners pay approximately $1,538 per year on electric bills. Once you pay off your solar array, you could reduce your costs by $1,729.84 per kilowatt you produce.

Is solar energy common in Danville?

Yes, solar energy is readily available in Danville. A growing number of local homes are already using solar power on-site or through utility grids, and California has about 74255 jobs forming its solar economy.

Will a solar PV system improve my Danville home worth?

Yes, a solar PV system will increase your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce on energy bills, your home value increases by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a gloomy or rainy

Even if your property has high tree cover, you could still use solar energy. Your technician will maximize your system's performance by choosing the proper site for panels, installing a battery backup system, cleaning them regularly, and positioning them to capture the most sunlight throughout the year. This way, you can keep solar energy longer and use it as necessary.

What's a Danville solar panel's average lifespan?

Today's solar installations are remarkably durable, lasting up to 25 years. Monocrystalline panels and other top-tier models tend to live longer than "budget-friendly" models.

What care do my solar panels need, and how frequently do they need it?

Solar panels don't require much upkeep to keep working well. All you'll need to do is inspect and clean the panels every six months or as necessary in dusty seasons. Solar installers frequently offer maintenance packages to help you in your system's care.

How does "net metering" work, and do I need to participate?

Net metering is a system that credits solar homeowners for any excess electricity they generate and send back to the grid.

Some states or energy providers mandate you to participate in net metering when installing your solar system, while others give you a choice. Either way, once you participate, you'll earn a bill credit or check for your excess generation at a retail or wholesale rate.

Should I get quotes from multiple Danville solar companies?

It's wise to collect three or more estimates before committing to a single solar provider. This lets you evaluate product quality, pricing, customer feedback, and warranty options. It also helps you assess an installer's responsiveness, knowledge and reliability, all of which are "green flags".
