Sifting through the best solar companies in Washington is time-consuming. Using most online company reviews to help find the best one can seem like a good idea, but most other reviews don’t consider the factors most important to WA residents. For example, Washington State gets a lot of rain, which puts your roof at risk of leaking. Therefore, companies that offer robust warranties on their workmanship and installation are typically best.

The EcoWatch team considers this factor and many others that are crucial in Washington to help you find the best solar company for your installation.

Ready to see which solar company is best for your home solar project? Because EcoWatch maintains so much brand authority in the solar space, we can typically get our readers the best pricing on solar conversions.

1. Puget Sound Solar

Puget Sound Solar is a local solar panel installation company based in Seattle. This company provides the outstanding service most customers expect from a smaller company. The technicians are highly communicative, knowledgeable and helpful, especially when it comes to helping you take advantage of rebates and solar incentives, like the federal tax credit. Most customers feel like they’re in good hands with Puget Sound Solar completing their conversion.

This company carries an enormous range of products and completes many different services above and beyond the standard panel and battery installations. You’ll have tons of customization options, plus electricians and general contractors at your disposal. As such, you can make your home more energy-efficient overall or couple installing a solar panel system with a remodel.

Puget Sound Solar only accepts cash purchases and solar loans, so customers looking for leases or Power Purchase Agreements — which we don’t recommend anyway — will need to look elsewhere.

Pros for Puget Sound Solar

Puget Sound Solar provides outstanding customer service, along with a huge array of photovoltaic equipment brands. It also backs its work with lengthy warranties that cover roof leaks, which are prevalent in Washington.

  • Great customer service
  • Many products and services available
  • Robust warranty coverage

Cons for Puget Sound Solar

There are few drawbacks to working with Puget Sound Solar. The only real negative aspects are the lack of solar leases and Power Purchase Agreements (PPAs).

  • No lease options
  • No PPAs

2. Solara Solar

Solara Solar provides best-in-class customer service to Washington solar customers. Most homeowners are blown away by the level of communication, the customization options available and the overall helpfulness of the company when it comes to maximizing refunds and minimizing cost and headaches. Solara also has long-standing relationships with local utility companies, so it can often expedite the process of interconnection for net metering.

Solara provides access to a large number of solar equipment brands, including some of the more popular ones like Enphase and SolarEdge. The equipment comes with a 25-year warranty to provide some peace of mind. However, the workmanship warranty is only good for 10 years, which is below the industry standard.

Solara provides tons of solar services, including energy monitoring and electrical and general contracting. It only accepts cash purchases and solar loans.

Pros for Solara Solar

Solara Solar excels above the competition when it comes to customer service. It has a wide range of products and services available as well.

  • Unparalleled customer service
  • Many products available
  • Wide range of services

Cons for Solara Solar

Solara Solar doesn’t accept leases or Power Purchase Agreements (PPAs). Additionally, the workmanship warranty isn’t as good as most competitors.

  • No lease options
  • No PPAs
  • Workmanship warranty isn’t great

Financing Options Cash payments, loans

3. SunPower

SunPower is a massive national company that, historically, has focused on manufacturing. It’s now transitioning to a different business model where it will handle installations of panels from its sister company, Maxeon. However, the current state of customer service is spotty due to third-party installations.

The panels provided by SunPower are some of the most efficient solar panels in the industry, and they are the most likely to help eliminate electric bills in a cloudy and rainy area like Washington. However, they do come at a higher cost than most competitors’ equipment.

SunPower covers its panels with a 25-year warranty on equipment, workmanship and production, which is ideal for Washington homeowners. It also accepts all financing options, including cash purchases, solar loans, solar leasing and Power Purchase Agreements (PPAs).

Pros for SunPower

SunPower provides access to some of the highest-efficiency panels in the industry. It accepts all financing options, and it provides robust warranties that provide peace of mind to Washington residents, in particular.

  • High-efficiency panels ideal for rainy Washington
  • Many financing options available
  • Great warranty coverage

Cons for SunPower

SunPower panels might be the most efficient, but they’re also rather pricey. Customer service can be spotty due to third-party installers. The company also only installs one brand of panels.

  • Expensive
  • Spotty customer service
  • Only one equipment brand available

4. Tesla Energy

Tesla Energy is best known for its involvement in electric vehicle design and production, but it also provides some of the highest-quality equipment in the residential solar industry. Best of all, while the solar roofing is prohibitively expensive for most, the panels and solar batteries are affordable and provide outstanding value. The company also offers a price match to make its clean energy solutions even more accessible.

Tesla outsources installation to third-party solar contractors, so the customer service experience can vary. Additionally, the company only installs its own products, so you won’t be able to choose from multiple equipment brands.

Tesla only accepts cash purchases and solar loans, so it’s not ideal for customers looking for leases or Power Purchase Agreements (PPAs).

It does have decent equipment warranty coverage, although the warranty covering installation only lasts for 10 years.

Pros for Tesla Energy

As a tech company, Tesla manufactures some of the highest-quality equipment in the industry and sells it at an amazing value. The company offers a price match to bring down costs even further.

  • High-quality equipment
  • Outstanding value
  • Offers price matching

Cons for Tesla Energy

Tesla’s customer service varies quite a lot due to outsourcing of installations. Its warranty coverage for labor and performance isn’t the best, and it only accepts cash purchases and solar loans.

  • Spotty customer service
  • Warranty coverage is lacking
  • No leases or PPAs

5. Northwest Renewables

We rarely recommend companies that have less than a decade of experience in the solar industry, but Northwest Renewables is one of the few exceptions. This solar installation company brings amazing customer service to the table, including quick responses, PV system customization and help with taking advantage of solar incentives. It maintains mostly positive customer reviews and an A+ rating with the Better Business Bureau.

Northwest Renewables has a good range of products available, including several popular and high-efficiency options suitable for Washington, like SunPower, Enphase and Panasonic. It has a nice array of services as well.

The warranty coverage for most products is good and around the industry average. However, it lacks a workmanship warranty, which is a significant downside. It also doesn’t offer access to leases or Power Purchase Agreements (PPAs).

Pros for Northwest Renewables

Northwest Renewables has quickly established a reputation for excellent customer service and customer care. It has many product brands available and completes a good number of services for solar energy system customization.

  • Great customer service
  • Many brands available
  • Completes a handful of services

Cons for Northwest Renewables

Northwest Renewables is a young company, so there is a lack of experience and longevity in the industry. It doesn’t have a workmanship warranty, and it only accepts cash purchases and financed deals.

  • Lack of experience and longevity
  • No workmanship warranty
  • No leases or PPAs

EcoWatch Criteria for Selecting the Top Solar Company in Washington

The EcoWatch team strives to bring you the best solar panel installation companies possible, which is why we assess installers based on more than 20 criteria. We’ll discuss the most prevalent factors below, but you can see our full list of qualifying factors on our methodology page.

Warranty

Solar panel installation is expensive, so warranty coverage for equipment damage and performance can provide some peace of mind as you invest tens of thousands of dollars.

In Washington, where rainfall is abundant and well above average for the nation, a workmanship warranty is usually the most crucial. This warranty covers roof leaks in most cases, which is the leading issue with going solar in Washington. Performance guarantees can also help ensure you offset your electric costs even during the common cloudy and rainy days.

Year Founded

We assess companies based on their longevity in the industry, which is crucial in a state like Washington, where solar is becoming more and more popular. Companies pop up all the time to capitalize on the demand, so young companies often provide subpar service and are more likely to go out of business, voiding your warranty in the process.

We give precedence to companies with a proven track record to help protect you from these “fly by night” solar installers.

Services Offered

Not every solar company is a full-service installer. Some only cover panel and battery installation, while others — like Puget Sound Solar — complete a huge array of services. If you’re looking for an electric vehicle charger, roof repair or energy monitoring, you might need to choose a specific company based on the services provided.

We give a higher rating to full-service companies because they’re more likely to be able to serve you.

Brands of Solar Equipment Offered

If you’re looking for the cheapest solar panels rather than the most efficient solar panels that are better suited for Washington homes, you might need to choose your installer based on the equipment it carries. Some companies carry just one or two equipment brands, while others carry a variety for customization. If you want a specific brand — like a Tesla Powerwall — you might be more limited in your company selection.

Companies that carry more equipment brands rank higher because they are more likely to appeal to the widest audience.

Industry Affiliations

In a solar-friendly state like Washington, we look to see if a company is affiliated with solar organizations. These include the Solar Energy Industries Association (SEIA), the North American Board of Certified Energy Practitioners (NABCEP) and Solar WA. Affiliations with non-profit and educational organizations like these suggest that a solar contractor strives to make renewable energy a better possibility and isn’t in the industry solely for profit.

Size of Company

The size of the company can be a surprisingly important part of installer selection. Smaller local companies usually provide better customer service and communication, and many can leverage long-standing relationships with local electric companies to expedite connection to the grid and net metering.

On the other hand, larger national companies typically buy equipment in bulk and can offer lower pricing. They usually have more employees as well and have better flexibility when it comes to installation timelines and consultations.

Solar Pricing and Financing

We also take a look at the overall price of going solar with a company, the value the installer provides, and the financing options available to customers.

The cost to go solar will always be important to homeowners, but some companies will have higher pricing not because of upcharges but because of higher-quality equipment being installed. We carefully weigh the cost against the value provided to determine which installer offers the best value for the money.

Additionally, not all companies accept the same financing options. Installers who take cash purchases, solar loans, leases, and Power Purchase Agreements (PPAs) will be accessible to most customers and rank higher in our ratings.
