Factors that Affect Solar Panel Costs in Washington

For many Washington homeowners, the decision to install solar panels depends on cost. However, the range of solar installation costs can be quite wide in Washington, with typical prices between $20,000 to $40,000. There are a number of factors that significantly influence the price you'll pay, which we'll go over below.

Solar Equipment Size

System size is one of the largest factors that determines the overall cost of installing solar panels. That's why it's important to accurately gauge the size of the solar energy system needed for your home by figuring out your energy needs. The brand and kind of equipment you choose for your solar system can raise or lower the price quite significantly. If you prefer a brand name like Tesla or SunPower, these often have a higher price tag 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 can expect a higher equipment cost, but this can typically lead to more savings over time. Plus, if you want add-ons like an electric vehicle charger or solar batteries, this will also increase the cost.

Solar Financing Terms

Most solar installers in Washington offer solar loans, which reduce your upfront costs of installing a solar system. You'll have to consider the long-term cost of financing options, including the amount of interest you'll pay over the length of the loan. If you can only 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 securing a solar loan with a low APR could reduce your costs considerably.

Solar Panel Installation Company

The solar installation company you choose will impact your total cost to go solar. Different companies will bill different amounts for the equipment and labor. Additionally, some companies in Washington have more knowledge about local solar incentives and can help you learn about additional rebates or tax exemptions. However, they may charge more for that service. Even if they cost more upfront, they could help you save more money in the long run.

  • Solar Panel Brands: Different companies will have various brands and types of panels. If you prefer a specific brand, make sure the solar installer you're considering has it.
  • Installation Process: When making the switch to solar energy, it's crucial to maintain an open line of communication with your solar panel company. Make sure you understand how the installation process works and the project completion timeline.

EcoWatch's Washington, OH Solar Cost FAQs

How much does it cost to install solar panels in Washington?

This is a hard question to answer exactly, because the cost depends on a few different factors. Generally speaking, it costs about $12,800 for a 5-kW system and $25,600 for a 10-kW system after the ITC is applied. It will be more expensive if you want other solar equipment or more efficient panels, or if you have above-average energy usage. On the flip side, you can spend less if you want a smaller solar panel system or cheaper solar panels.

Should I lease or buy solar panels in Washington?

Leasing solar panels can be an attractive choice, as it often comes with low or $0 upfront payments. The downside is that you won't be able to save as much. If you lease, you don't own the system, so you can't claim any incentives and your home value won't increase. Buying solar panels is a better way to go if you want to get the most savings.

How will having solar panels impact how much my home is worth?

Solar panels can increase the value of your home considerably as long as you buy or finance your panels and don't opt for a solar lease or power purchase agreement (PPA). According to research done by Zillow, the average home value increases by about 4.1% after installing solar panels."

What solar power system size is right for my home?

The exact number of solar panels you need depends on your household energy usage and the average daily sunlight your roof gets. You can look at your energy bills for the past year to get an idea of the solar system size you'll need. The average household has to buy between 20 and 35 panels to account for their typical energy usage.
