Factors that Affect Solar Panel Costs in Washington
Although the average cost of a solar system in Washington is $16,890, your final cost may be above or below the average. There are quite a few factors that can have a major impact on the cost of a residential solar panel installation. Below are some of the more important things to take into consideration.
Solar Equipment
The size of the solar system you need to offset your energy usage, 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 around $3,510. The kind of solar equipment you choose can bring your price up or down by thousands or even tens of thousands of dollars. If you choose the most efficient solar panel brands, you’ll end up paying more upfront than if you opted for the most affordable panels. However, more efficient panels could save you more in the long run on your electric bills. Additionally, add-on products, like solar batteries, can bump up your total well above the Washington average.
Solar Financing Terms
Solar panels can save you money on utility bills over time, but they can also be a big investment. That’s why many Washington homeowners choose to finance their solar panel systems to offset upfront costs.You’ll have to consider the long-term cost of loans, including the amount of interest you’ll pay over the length of the loan. If you’re only able to 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 finding a solar loan with a low interest rate could reduce your costs significantly.
Solar Panel Installation Company
A final consideration when trying to figure out the cost of solar for your home or business in Washington is the company you get to install your PV system. Similar to choosing a company to build a deck or pool, for example, there are plenty of solar installers that provide a range of services at different costs.You may see national solar installers that have lower prices because of their larger brand name and access to bulk pricing, or you might see small, local installation companies offering deals or promotions to compete with those major players.

How to Save on Solar Panels
The company that does your solar system installation will affect the warranties and brands available to you, and it will also have an impact on your total cost. Because picking a company can be a tough decision, we have some tips to help you, such as:
- Contract: It’s important to read through your solar installer’s contract closely to understand what services they will provide, what the warranty covers and what you can expect about the cost.
- Installation Process: Make sure you’re aligned with the installer regarding how the installation process will go and what you need to do before your solar panels are installed, such as updating your electrical system or roof.
- Solar Panel Brands: Not all solar companies offer the same brands of solar panels, so the brand and type of panel you want can play a substantial role in the company you opt for.
