How to Pick the Best Solar Company in Washington: Step by Step

Picking a solar vendor in Washington may be more challenging than you think, considering more than 150 companies deal in solar products. Moreover, homeowners may perceive what makes a good solar company differently. Some prioritize installation costs, while others are more concerned about warranties. So, how do you pick the right company in Washington? Let’s take a look at some important factors.

  • Knowledge of Washington’s solar market
  • Excellent customer service
  • Accredited installers and dealers
  • Flexible financing options

Let’s take a look at each of these criteria in more detail.

Knowledge of Washington’s Solar Market

Pick a solar company that understands Washington’s climate and the local solar market. Washington has among the lowest average peak sun hours. That means factors like the direction the solar panels face and the degree to which they tilt influence their energy output. Local solar companies that have installed several thousand solar panels in Washington are better placed to assess your roof and design a solar system that guarantees maximum output.

Excellent Customer Service

Prospective customers often rush to solar companies offering the cheapest installation costs and overlook the expected customer service. You do not want to work with a solar company that often ignores customers’ complaints and concerns.

The best way to gauge a company’s customer service is by checking its online reviews. Companies with frequent complaints of unanswered phone calls and emails are a red flag. We recommend picking a solar company with a dedicated customer support department — it is even better if it has a 24-hour response team.

Accredited Installers and Dealers

We recommend working with solar companies that have been accredited to stock and install solar systems in Washington. Accreditation means the solar company stocks genuine solar products.

Most solar product manufacturers also require vendors to hire trained and licensed technicians. Confirm that the solar company you pick has REC or NABCEP-certified professionals. Do your due diligence before committing to a specific solar company to avoid future issues regarding workmanship errors and void warranties.

Flexible Financing Options

A 6kW solar energy system in Washington costs about $17,000 before deducting federal and state tax incentives. However, the amount drops to around $12,000 after deductions — this is still a huge amount for most Washington residents to pay upfront.

Most solar companies in Washington offer financing options, such as leases, loans, and power purchase agreements, to make solar systems affordable. Pick a solar company whose financing options suit your financial situation. This allows you to repay the loan on time and reduces your default risk.

Wrapping Up

Washington only has an average peak sun of 3.57 hours, but it is enough to sustain a solar energy system. Residents can switch to solar power to reduce their monthly power bills and contribute to environmental conservation.

This is the best time for Washington residents to switch to solar power and benefit from federal and state incentives. Those who switch to solar power qualify for a 30% federal tax incentive and an additional 9% sales tax exemption, saving them more money.

Finally, the large number of solar companies in Washington allows clients to benefit from competitive pricing. Most companies offer enticing rates and flexible payment plans to gain a competitive advantage. Prospective customers can leverage this to bargain for discounts.

Ultimately, Washington residents considering switching to solar energy systems can approach any company on this list and request a free quote.
