Benefits of Solar Energy

Solar energy offers multiple perks. Let's look at a few of them.

  • Lower energy bills: Generating some or all of your own energy will save you money on your electric bills long-term. Plus, some states provide net metering programs that make it possible for you to sell your extra energy back to the grid, generating additional credits toward your energy bill.
  • Reduced carbon footprint: Solar is one of the universe's most abundant clean energy sources, meaning you can lower or beat your home's dependence on fossil fuels.
  • Better energy independence: Adding a battery storage system lets you have dependable energy during grid outages and storms.

What Solar Incentives Are Available to Washington Homeowners?

How To Choose the Best Solar Company in Washington

The cost and efficiency of solar panels often rely on the solar company that installed them. Make your choice based on the following key factors.

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 accreditations. Two of the most respected are the PV Installation Professional and Solar Heating Installer certificates, granted 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

Your solar modules' type will impact how much electricity you can generate. 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 companies include these optional components, so look for a contractor that installs them if it's essential for you.

Generally speaking, it will cost about $17,700 for a five-kilowatt solar array in Washington. This table lists more specific costs for different solar panel types and system components in your area.

Solar Panel CostAverage 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

There are various ways to pay for a solar energy system, and the right one will lower your costs. A few of the most common options include power purchase agreements (PPAs), loans, cash payments, and leases. 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. Like a home or auto loan, you'll pay a set monthly rate with potentially $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 solar 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.

Frequently Asked Questions About Solar in Washington

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

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?

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

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. Your surrounding shading, panel model, and roof size could also impact your final result. A professional solar company will consider these factors and determine the right array size for your home.

How long does it take to pay back a solar loan in Washington?

The average payback period for a solar loan in Washington is 19.1 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

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

Even the most renowned Washington solar providers will have both glowing and unfavorable reviews. To make the most informed choice possible, focus on these signs to know if a company isn't worth your attention:
  • 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
