Benefits of Solar Energy

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

  • Better energy independence: Photovoltaic systems with battery storage work through power outages and emergencies, and you won't have to depend on your power company for your safety and comfort.
  • Lowered energy bills: With a solar array, you generate power without paying the tacked-on costs of grid-tied power. Going off-grid can eliminate your bills completely.
  • Reduced carbon footprint: Solar is a highly abundant clean energy source, meaning you can minimize or conquer your home's dependence on fossil fuels.

How To Choose the Best Solar Company in Seattle

Choosing a company is the first step toward an effective and valuable solar system. Here are some essential aspects to consider while searching for a solar specialist.

Licensing and Training

Solar installers in Washington must hold an electrical contractors' license from the Department of Labor and Industries. In some situations, the department may also conduct permit inspections to test compliance and the viability and integrity of a contractor's job. You should also visit a company's website to learn about its private certifications. Two of the most prestigious are the PV Installation Professional and Solar Heating Installer 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 Seattle

Different solar panel types look and perform differently. Monocrystalline panels offer the best energy production but cost more than other options. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

You can also add battery backups and electric vehicle (EV) chargers. These will increase your total project price, but they can maximize your solar system's performance. Not every solar company provides these additional features, so look for a company that sells them if it's a priority for you.

Most Seattle homeowners choose solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $17,950 to install, considering both parts and installation. You can see more specific cost information in the table.

Solar Panel Cost Average Cost
Solar Monocrystalline $1,255
Solar Polycrystalline $979
Thin-Film $572
Solar Battery $803
Solar Home EV Charger $3,012

Financing Solar Energy in Seattle

Choosing the ideal financing solution will affect your overall solar system cost and possible savings. Common payment options include power purchase agreements, cash payments, leases, and loans. Though it requires a large up-front payment, cash is the most economical choice because it qualifies you for solar incentives and doesn't accrue interest. Solar loans are the runner-up option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for cost-saving 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 determined by the energy you use, akin to 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 suggest working with an installer that offers multiple financing options. Talk to each representative about what's available, and secure more than one estimate for the best odds of staying within your budget.

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

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.

Solar System Capacity Estimated Payback period
1 kW 2.5 years
2 kW 5.0 years
5 kW 12.4 years
10 kW 24.9 years

Frequently Asked Questions About Solar in Seattle

How much energy and money could I save per year by switching to solar?

On average, Seattle homeowners pay approximately $1,378 per year on power bills. Once you repay your solar array, you could save $862.14 for every kilowatt you produce.

Is solar energy easily accessible in Seattle?

Yes, solar energy is gaining popularity in Seattle. Some homes already use solar power on-site or through utility grids, and they're supported by a state solar economy with 3781 jobs and counting.

Will solar panels increase my Seattle home worth?

Yes, a solar PV system 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.

How long is a Seattle solar panel's average lifespan?

Today's solar installations are remarkably durable, lasting up to 25 years. Monocrystalline panels and other premium models tend to live longer than less expensive models.

Is installing solar panels a fast job?

Your solar job's duration will depend on its size and complexity, as well as Seattle's permit and inspection procedures. It could take several weeks to a couple of months on average.

What is the average payback period for Seattle solar panels?

The average payback period for a solar loan in Seattle is 14.6 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

What are the signs I shouldn't use a particular solar company for my job?

While many online reviews are positive, even the rated solar installers might have unhappy customers. You should know these early red flags for the best chances of an exemplary job:
  • High-pressure sales tactics
  • Dodging questions about warranties, references, credentials and training and cost
  • Inflexible options
  • Rushing through the site assessment
  • Limited online information

What's the difference between a PPA and traditional financing?

A PPA is an agreement between you and your provider. They install, own, and maintain the panels, and you buy the generated electricity from them for 10–25 years. There will usually be options to extend the agreement and buy out early to own your system.

In contrast, solar loans can come from installer, specialty lenders, local banks and the government. You'll need to pass a credit check to qualify for most of them. While the upfront costs are greater, and you'll be responsible for taking care of the system, you'll also have total ownership and can apply for many more incentives.
