Factors that Affect Solar Panel Costs in Washington
Even though the average cost of a solar system in Washington is $24,787, your final cost may differ. There are many factors that can have a significant impact on the cost of a solar panel installation. Below are some of the more important things to consider.
Solar Equipment
Solar system size, which is measured in kilowatts, is one of the largest factors that determines the overall cost of installing solar panels. Because of that, it’s crucial to accurately assess the size of the solar energy system needed for your home by figuring out your average energy use.There are a lot of different solar panel brands and the one you choose also affects the cost. Generally, the brands that are more efficient tend to also cost more. Additionally, the type of equipment you’re looking to get can affect your total cost. If you just need panels, your system will be much less expensive than if you also need solar batteries or an electric vehicle charger.
Solar Financing Terms
Many homeowners find the average cost of solar in Washington to be too steep, even if the investment pays off over time. Thankfully, almost every solar company in the area provides financing options. Solar loans substantially decrease upfront costs in most cases, but they also result in paying more over time due to interest.While solar loans make switching to solar energy more accessible for Washington homeowners, they can also increase the total you pay for your system due to interest. If you put down a larger down payment, though, you can cut back on how much interest you have to pay.
Solar Panel Installation Company
The solar installer you hire to handle your switch to solar energy can play a part in your total costs. There are about 3 solar installation companies in Washington, and each can charge different amounts for labor and equipment.You may notice national solar installers that have lower prices because of their larger brand name and access to bulk prices, or you might see small, local installation companies offering deals or promotions to compete with those larger companies.
