Factors that Affect Solar Panel Costs in Washington

The cost of installing a solar system in Washington can vary by more than $10,000 from home to home. Your actual cost depends on several factors. The biggest one is the size of the system your household needs, and other factors include the equipment you choose, financing options and the solar installer you choose.

Solar Equipment

The cost of solar panel systems varies by thousands of dollars due to a few different factors. One of the most significant factors is the system size, which is measured in kilowatts (kW). Solar power systems that have higher efficiency or power production require better technology and/or more equipment, both of which can raise costs. For each additional kilowatt you need, your cost can go up by about $2,550. 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 opt for 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, such as solar batteries, can bump up your total well above the Washington average.

Solar Financing Terms

For some homeowners, paying for a solar system out of pocket can be difficult. Solar loans are provided by most installers in Washington, which can reduce, or in some cases eliminate, your upfront costs to make solar more affordable. However, the interest on solar loans also adds to your all-in costs, so it's vital to take that into consideration as well. You can always reduce the total you pay in interest and in some cases even your APR by making a larger down payment.

Solar Panel Installation Company

The solar panel installer you select will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Washington are more knowledgeable about local solar incentives and can help you take advantage of additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

How to Save on Solar Panels

Since the type of solar panels and the installer you choose has an impact on your costs and your system's durability and efficiency, it's important to select the right ones for you. Here are some tips to keep in mind to help with your decision:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a well-established certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it most likely has a solid reputation and is qualified to install your solar system. Another way you can verify your installer's reputation is by reading reviews.
  • Solar Panel Brands: Different companies carry various brands and kinds of panels. If you know you want a specific brand, make sure the solar panel installer you're considering has it.
  • Installation Process: An important thing to understand when going solar is the installation process itself. Be sure to align on any details you need to know with your solar company, such as what permits you should secure and how long the project will take.
  • Contract: Although reading through a contract can be tedious, it's important to do it fully so you can make sure you understand what services your solar company will provide and the terms of the warranty.
