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 largest one is your system size, and other factors include equipment choices, financing options and the solar installer you choose.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of going solar. Because of that, it's a priority to accurately ascertain the size of the solar energy system needed for your home by figuring out your average energy use. The brand and type of equipment you get for your solar system can increase or decrease the price quite significantly. If you prefer a trusted 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 limited roof space or just want maximum energy production, you will be looking at a higher equipment cost, but this can typically lead to greater savings over time. Also, if you want additional equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Most solar companies in Washington provide solar loans, which reduce your upfront costs of installing a solar system. When estimating your overall cost, you should also calculate the interest you'll pay if you choose to go with a solar loan. Also, paying a higher down payment can lower the total interest paid over time.
Solar Panel Installation Company
The solar company you hire to handle your switch to clean energy can play a role in your total costs. There are about 3 solar panel companies in Washington, and each can charge different amounts for labor and equipment. You may see national solar installers that have lower prices because of their bigger brand name and access to bulk equipment pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

What is the average cost of installing solar panels in Washington?

Generally speaking, it costs about $13,400 for a 5-kW system and $26,800 for a 10-kW system after the ITC is applied. You can expect to pay more if you want other solar equipment or more efficient panels, or if you have higher-than-average energy usage. On the flip side, you can spend less if you choose a smaller solar panel system or cheaper solar panels.
What other factors should I consider apart from cost when buying solar panels?
Cost is definitely one of the most important factors you should consider when buying solar panels, but other important factors include efficiency, durability, and quality.
How will having solar panels impact the value of my home?
Solar panels can increase the value of your property by about 4%, according to research done by Zillow.

The exact figures will vary, but most experts agree that installing solar panels in Washington is a rewarding investment.
How many solar panels do I need to power my home?
To figure out what solar panel system size 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 usually produce about 250 to 400 watt-hours per hour, the average house will need 20 to 35 panels.
