Benefits of Solar Energy

Solar energy offers multiple advantages. Here are some highlights.

  • Lowered energy bills: Solar panels allow you to generate your own energy to power your home, reducing your regular electricity costs. You can eliminate your bills completely if you go off-grid. Plus, a significant amount of states have adopted net metering, which permit you to earn money by selling your unused energy back to the grid.
  • 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 solar battery storage system lets you have trustworthy energy during grid outages and storms.

What Solar Incentives Are Available to Washington Homeowners?

How To Choose the Best Solar Company in Washington

The price and efficacy of solar panels often depend on which company installed them. Here are some important factors to remember while searching for a solar installer.

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, 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

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power and generally have the highest quality. Polycrystalline panels provide a lower price point but produce less power. 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 installation cost, but they can maximize your solar system's performance. Not all solar contractors provide these additional features, so look for a company that installs them if it's essential for you.

Generally speaking, it costs about $17,700 for a five-kilowatt solar array in Washington. This table shows more specific prices 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 reduce your expenses. A few of the most common options include leases, power purchase agreements (PPAs), cash payments, and loans. We suggest making a cash payment or using a solar loan for the highest 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 panel incentives to minimize your total costs. Solar loans are another good option if you don’t want to make a big initial investment. You can pay for your system in installments while still benefiting from energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases allow you to pay a monthly fee to rent your panels, while a PPA lets you pay a variable rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be suitable in specific circumstances. Look for providers that offer two or more payment plans to find the right fit for your wallet.

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. Municipal and state governments and utility companies might also offer rebates, discounts, and specialized financing options that could save you more.

Solar System CapacityEstimated Payback period
1 kW3.3 years
2 kW6.5 years
5 kW16.3 years
10 kW32.6 years
