Factors that Affect Solar Panel Costs in Washington
For many Washington homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Washington, with typical prices between $20,000 to $40,000. There are numerous factors that significantly influence the price you’ll pay, which we'll go over below.
Solar Equipment
One of the most important factors to consider when it comes to the cost of installing solar panels is the size of the solar system, which is measured in kilowatts (kW). The more energy your household uses, the larger your system will likely need to be. You can expect to spend around $3,650 per kilowatt in Washington.The type of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you get the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, higher efficiency could save you more over time on your electric bills. In addition, extra products, like solar batteries, can bring your total well above the Washington average.
Solar Financing Terms
If paying for a solar system out of pocket is too expensive, solar loans are a solid route because they lower your upfront costs and let you pay for your system over a term of, on average, between five and seven years.However, the interest on solar loans also increases your total costs, so it’s important to take that into consideration as well. You can always lower the total you pay in interest and sometimes even your APR by making a larger down payment.
Solar Panel Installation Company
The solar installer you go with to handle your switch to solar energy can have an effect on your total costs. There are about 3 solar installation companies operating in Washington, and each can charge varying amounts for labor and equipment.The company’s size sometimes plays the most significant role in the cost. Larger national companies, like SunPro and Sunrun, often have lower pricing because they have access to greater resources and bulk pricing. Smaller local companies might be more costly, but they generally have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

Solar panels can potentially eliminate your electricity bills depending on where you’re located and the efficiency of your system. Even if it doesn’t get rid of them completely, you can save a lot of money on your bills, about $887.12 per year.
What solar power system size is right for my home?
