Factors that Affect Solar Panel Costs in Washington

For many Washington homeowners, the decision to go solar rests 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 several factors that considerably influence the price you'll pay, which we'll go over below.

Solar Equipment

When it comes to estimating the price of a solar energy system in Washington, one of the most important factors is the size of the system you need. Solar systems are sized by kilowatts (kW) and are largely based on your home's energy usage, which you can determine by looking at past power bills. Your overall cost can increase by about $2,950 for each additional kilowatt you need. There are a lot of different solar panel brands and the one you pick also affects the cost. Usually, the brands that are more efficient tend to also be more expensive. In addition, the type of equipment you're looking to get can affect your total cost. If you just need panels, your system will be far less expensive than if you also need solar batteries or an electric vehicle charger.

Solar Financing Terms

Solar panels can save you money on utility bills over many years, but they can also be a significant investment. That's why many Washington homeowners decide to finance their solar panel systems to make going solar more affordable. It's a good idea to include the interest you'll pay in your final cost estimate. If you can afford to put more money down upfront, you can reduce your total costs and the amount of time it'll take to pay back the loan.

Solar Panel Installation Company

Finally, the company you choose to install your solar panel system can influence your pricing. Washington's solar companies all have different labor costs and add varying upcharges to equipment. The company's size can sometimes play the most considerable role in the cost. Larger national companies, like SunPro and Sunrun, often have lower prices because they have greater resources and bulk pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing down to compete with bigger names.

How to Save on Solar Panels

The solar panel company you choose will affect not only your overall costs, but also the types of solar panel brands, warranties, and other equipment you have access to. When choosing a solar company, there are a few important things you should take into account, including:

  • Reputation: The North American Board of Certified Energy Practitioners (NABCEP) is a respected certification organization for renewable energy professionals. If your solar panel installer is NABCEP-certified, it likely has a solid reputation and is qualified to do the job well. Another way you can verify your installer's reputation is by reading reviews.
  • Warranty: Warranties that cover panel repairs and maintenance over around 25 years are the best you can get in the business, and offering that kind of warranty is one sign of a good company.
  • Solar Panel Brands: Different companies offer different brands and types of panels. If you want a specific brand, make sure the solar installer you're considering has it.
  • Contract: Even though reading through a contract can take a lot of time, it's important to do it carefully so you can be sure you understand what services your solar company will provide and the terms of the warranty.
