Factors that Affect Solar Panel Costs in Washington
For many Washington homeowners, the decision to adopt solar energy 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 a number of factors that considerably influence the price you’ll pay, which we'll go over below.
Solar Equipment
The size of the solar panel system you need, which is measured in kilowatts, is the most significant cost factor to consider. For every additional kilowatt you need, your total will most likely increase by nearly $3,740. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer better efficiency. In a city like Washington, where sunlight is abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don’t have a lot of space for your panels, higher efficiency options will be more impactful. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.
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 completely eliminate, your upfront costs to make solar more accessible.You’ll have to consider the long-term cost of financing options, including the amount of interest you’ll pay over the length of the loan. If you can only get a high-interest loan, then your total can be hundreds or even thousands of dollars above the equipment and labor cost. Making a larger down payment or securing a solar loan with a low interest rate could reduce your costs remarkably.
Solar Panel Installation Company
The remaining key cost factor you should consider is the installer you choose. Given the massive popularity of clean energy solutions in Washington, you’ll have many options to choose from, but each comes at various price points for labor and equipment.You may notice national solar installers that have lower prices due to their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.

How to Save on Solar Panels
There are a large number of companies available in Washington, and some homeowners feel overwhelmed considering their options. Choosing the right company for you can be tough, so here are some tips to help you decide:
- Solar Panel Brands: Not all solar companies carry the same brands of solar panels, so the brand and type of panel you want can play a significant role in the company you choose.
- Contract: It’s important to read your solar installer’s contract closely to understand what services they will provide, what the warranty covers and what expectations you should have about the project timeline.
- Warranty: Warranties that provide coverage for defective panels and repairs over a long period of time such as 25 years are the best you can get in the business, and offering such a warranty is one mark of a quality company.
- Installation Process: Get details from your solar company about the installation process and what to expect, such as when the site survey will be done and how long it will take.
