  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Better energy independence: Adding a solar battery lets you have trustworthy energy during grid outages and storms.

How To Choose the Best Solar Company in Washington

Choosing a company is the first step toward an effective and cost-efficient solar system. Consider each of these factors in your contractor search.

Licensing and Training

To install solar energy systems in Washington, D.C., a contractor must be licensed in the trade for which the system is designed. Photovoltaic installers must be licensed electricians, solar HVAC installers must have an HVAC license and solar water heater installers must be licensed plumbers. You should also visit a company's website to learn about its private certifications. Two of the most respected are the PV Installation Professional and Solar Heating Installer 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 Washington

The style of solar panels you select determines how much electricity you can generate. Monocrystalline panels cost more but give you the best performance. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't meant for large home installations, but they're excellent for small projects like sheds and RVs.

Additional accessories, such as battery storage and electric vehicle (EV) chargers, will add to your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar contractors offer these extras, so look for a provider that installs them if it's crucial for you.

If you're a resident of Washington and are considering getting a five-kilowatt solar energy system, you could expect to pay about $17,700 for materials and labor. See more information on specific component and panel costs in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,212
Solar Polycrystalline $945
Thin-Film $553
Solar Battery $776
Solar Home EV Charger $2,908

Financing Solar Energy in Washington

Choosing the best financing solution will impact your overall solar system cost and expected savings. Common payment options include power purchase agreements, loans, cash payments, and leases. Though it requires a large up-front payment, cash is the most economical choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the next best option. As with a car or home loan, you'll pay a monthly rate towards system ownership, including interest. You can still apply for valuable 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) lets you pay a monthly rate based only on the energy you use, as with an electric bill. We generally don’t recommend these two options because you won't own the panels and are disqualified from using solar incentives. We advise working with a contractor that offers multiple financing options. Talk to each consultant about what's available, and acquire more than one estimate for the best odds of keeping within your spending limits.

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

You are eligible for a 26% federal tax credit for new solar energy devices until the year 2032. Local and state governments and utility companies might also offer rebates, discounts, and specialized financing options that could save you more.

Solar System Capacity Estimated Payback period
1 kW 3.3 years
2 kW 6.5 years
5 kW 16.3 years
10 kW 32.6 years

Most Washington homeowners spend about $999 on energy each year. Your costs could drop by $649.65 for each kilowatt you generate after you pay off a solar array.

Is solar energy common in Washington?

Yes, solar energy is readily available in Washington. A growing number of local homes already use solar power on-site or through utility grids, and District of Columbia has about 1051 jobs comprising its solar economy.

Should I anticipate a property value increase after installing solar panels?

Could I still use solar power if I live in a rainy, wooded, or dark area?

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

What's the average solar system size in Washington?

The average Washington solar system size is 8.4 kilowatts (kW). However, your final system size depends on your household's energy needs.

What are some "red flags" to watch for as I research companies?

  • Pushy sales approach
  • Being evasive about warranties, training and credentials, cost and references
  • "One-size-fits-all" approach
  • Not thoroughly inspecting your site
  • Limited online information
