Factors that Affect Solar Panel Costs in Washington

For many Washington homeowners, the decision to install a solar energy system 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 a few factors that greatly influence the price you’ll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the cost of a solar panel system in Washington, one of the most crucial factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are chiefly based on your home’s energy consumption, which you can gauge by looking at past energy bills. Your total cost can increase by about $3,340 for each additional kilowatt you need.The brand and kind of equipment you want for your solar system can increase or decrease the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often come at a higher price than other brands. Efficiency also matters. Whether you’re opting for high efficiency because you have a small roof or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

If paying for solar panels in cash is too expensive, solar loans are an affordable route because they reduce your upfront costs and allow you to pay for your system over five to seven years on average.However, the interest on solar loans also increases your total costs, so it’s vital to take that into consideration as well. You can always bring down the total you pay in interest and sometimes even your APR by making a larger down payment.

Solar Panel Installation Company

A final factor to consider when trying to estimate the cost of solar for your home or business in Washington is the company you choose to install your solar system. As with choosing a company to install new cabinets, for example, there’s no shortage of solar installers that provide a range of services at different price points.Companies that only sell products with high efficiency and therefore a higher price point — like Maxeon solar panels from SunPower or Tesla Powerwall batteries — so choosing those installers will generally come with an above-average cost. It’s best to do some research and choose a company that has the products, warranties and services you want and also fits within your budget.

How to Save on Solar Panels

The solar company you opt for will be a major factor in determining not only your overall costs, but also the kinds of solar panel brands, warranties, and other equipment you can get. When choosing a solar company, there are several important things you should take into account, including:

  • Reputation: Well-established companies likely have a solid reputation. This is important because it ensures that it will not only see your solar installation through, but will also provide adequate aftercare and customer service, such as part repairs and replacements.
  • Installation Process: When making the switch to solar energy, it’s necessary to maintain an open line of communication with your solar panel installer. Confirm that you understand how the installation process will go and the completion timeline.
  • Contract: It’s important to look over your solar installer’s contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the cost.
  • Solar Panel Brands: Different companies will offer different brands and types of panels. If you want a specific brand, make sure the solar company you’re considering has it.

EcoWatch's Washington, KS Solar Cost FAQs

How much does it cost to install solar panels in Washington?

The average cost of solar panels in Washington is about $16,700 for a 5-kW system and $33,400 for a 10-kW system before the ITC, but the actual cost will depend on stuff such as the type of solar panels you want, what size system you need and how much energy you use.

Should I lease or buy solar panels in Washington?

Leasing solar panels can be an appealing choice, as it often comes with low or $0 upfront payments. The drawback is that you won’t be able to save as much. If you lease, you don’t own the system, so you can’t claim any tax rebates and credits and your home value won’t increase. Buying solar panels is a better way to go if you want to maximize your savings.

Is switching to solar power worth it?

Solar panels can be a fruitful investment for a majority of homeowners, but they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight and/or your power bills are already fairly low, solar panels might not be for you.

How many solar panels should I get to power my home?

To figure out how many solar panels you need, you should find out how much energy your home requires and how much sunlight your home gets. For a general estimate, however, since each panel can typically produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
