Factors that Affect Solar Panel Costs in Washington
Even though the average cost of a solar system in Washington is $17,270, your actual cost may be above or below the average. There are many factors that can have a significant impact on the cost of a solar system installation. Below are some of the more crucial things to keep in mind.
Solar Equipment
The size of the solar energy system you need for your home, 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 about $4,060. The brand and type of equipment you want 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 a small roof 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 extra equipment like an electric vehicle charger or solar batteries, this will also increase the cost.
Solar Financing Terms
Most solar installers in Washington have solar loans, which reduce the initial cost of installing solar panels.It’s wise to include the interest you’ll pay in your final cost estimate. If you can afford to pay a larger down payment, you can reduce your total costs and the amount of time it’ll take to pay back the loan.
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 choose to install your PV system. Similar to choosing a company to renovate your kitchen, for example, you’ll have no shortage of solar installers that provide a range of services at different costs.The size of the company can sometimes play the most significant role in the installation costs. Larger national companies, like SunPro and Sunrun, often have lower prices because of access to more resources and better pricing. Smaller local companies might be more costly, but they can sometimes have better customer service and more customization options, and the occasional sale or promotion can bring their pricing lower to compete with bigger companies.

EcoWatch's Washington, MI Solar Cost FAQs
What is the average cost of installing solar panels in Washington?
The average cost of solar panels in Washington is about $20,300 for a 5-kW system and $40,600 for a 10-kW system before the ITC, but the real cost will depend on certain factors like the kind of solar panels you want, what size system you need and how much energy you consume.
What other factors should I consider in addition to cost when buying solar panels?
The initial cost is a crucial factor to consider, but whether it’s the most important for you depends on your reasons for going solar. In places where rooftop space is limited, efficiency can trump the cost. Other factors that are important to think about are the quality and durability of your solar panels.
How much can I save on electricity bills after installing solar panels?
It is possible to eradicate your electricity bills with solar panels, but for most homeowners throughout Washington, that will require at least a 10-kW system. Not all homes will have roofs that can accommodate that size system, so you’ll want to check with a local solar installer to see how many panels can fit on your roof.
How long do solar panels last in Washington?
Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely at that time. What this means is their energy production will have decreased significantly after that point. You can replace them after having them for that long or you can continue to use them at a lower efficiency.
