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 the size of the system your household needs, and other factors include the equipment you choose, 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 influences the overall cost of installing solar panels. For that reason, it's crucial to accurately ascertain the size of the solar energy system needed for your home by figuring out your typical energy use. Some solar brands — like Maxeon from SunPower — are more expensive upfront but also tend to offer higher efficiency. In a city like Washington, where sunlight is abundant, efficiency can quickly pay off. In addition, if you have a small roof or you don't have a lot of space for your panels, higher efficiency options will be a better option. Additional equipment like electric vehicle chargers and solar batteries will also increase the cost.

Solar Financing Terms

For some homeowners, paying for solar out of pocket can be a challenge. Solar loans are provided by most installers in Washington, which can lower, or in some cases eliminate, your upfront costs to make solar more accessible. You'll have to consider the long-term cost of loans, including the total 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 more than the original 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

The final major cost factor you should keep in mind is the installer you choose. Given the massive popularity of green energy solutions in Washington, you'll have lots of options to choose from, but each comes at various price points for labor and equipment. You may notice national solar installers that have lower prices because of their bigger brand name and access to bulk equipment prices, or you might see small, local installation companies offering deals or specials to compete with those major players.

How to Save on Solar Panels

Since the brand of solar panels and the installer you choose greatly impacts your costs and your system's durability and efficiency, it's important to pick the right ones for you. Here are some things to keep in mind to help with your decision:

  • Installation Process: Homeowners should make sure they know how exactly the installation process will be carried out, as well as important factors like the project completion timeline.
  • Reputation: Companies that have been operating for many years likely have a high reputation. This is important because it ensures that it will not only see your solar project through, but will also provide quality aftercare and customer service, such as part repairs and replacements.
  • Solar Panel Brands: Each solar panel brand and kind has varying levels of quality, durability and efficiency. They will come at different prices as well. The company you choose impacts which solar panel brands you have access to.
  • Contract: It's important to look over your solar installer's contract carefully to understand what services they will provide, what the warranty covers and what you can expect about the cost.

EcoWatch's Washington, NC Solar Cost FAQs

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

The average cost of solar panels in Washington is about $12,700 for a 5-kW system and $25,400 for a 10-kW system before the ITC, but the real cost will depend on stuff like the type of solar panels you want, what size system you need and how much energy you use.

Is it better to lease or buy solar panels in Washington?

Leasing solar panels can be an attractive choice, because it commonly 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 maximize your savings.

Do solar panels increase your home value?

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

How often do you have to replace solar panels?

Although the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable at that time. What this means is their energy production will have decreased significantly after that point. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency.
