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.

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.
