Going solar can be one of the most important investments you will ever make to your home. It can give you decades of lower electricity bills. But if you want to realize those benefits, you need to find the right contractor. It can mean the difference between a potentially profitable experience and an expensive nightmare.

It all comes down to asking the right questions, so here are some that you should ask solar installers before you decide to hire them.

#1: How Long Has Your Company Been in Business?

In business, longevity is often a result of financial responsibility and experience. A company that has made it through market fluctuations is more likely to be around to service your system in the next 10-15 years. You want to look for a company that has been installing solar panels for at least five years. It means that they have a proven track record and have moved beyond the initial startup phase. Be wary of companies that are less than 2-3 years old, have recently changed their name, or aren’t able to give you a clear history.

#2: What Licenses and Certifications Do You Have?

Having the proper licensing will make sure that the company is legally allowed to do the work and is able to meet both state and local standards. Certifications from reputable organizations (such as the North American Board of Certified Energy Practitioners) proves that they have a higher level of expertise and a commitment to quality.

They need to provide a clear list of their state and local license numbers. If they show any signs of hesitation to give you this information or claim that they “don’t need them,” it’s a red flag that you shouldn’t ignore. You also want to verify everything with your state’s licensing board.

#3: Can You Provide References from Recent Customers?

It can be helpful to read online reviews, but speaking directly with their previous customers will give you access to unfiltered feedback about the company’s process. Local references will also prove that they have experience working in your specific area.

They should have a list of 3-5 of their most recent customers, which any reputable company will be happy to do. Refusing to provide this information, only offering old references, or sending you pre-written testimonials on their website is a major red flag.

#4: What Happens to My Warranty if Your Company Goes Out of Business?

This is one of the most important questions to ask before you hire someone for a solar installation. Many installers offer a “workmanship warranty” that covers any errors in the installation. But if they go out of business, it could become useless (which will leave you having to pay for any repairs).

The equipment will be backed by the manufacturer, so those warranties will be intact. But the solar installation company should offer a third-party insured warranty or use equipment that’s known to be stable and have robust warranties. If they dismiss the question or say that they’re not going anywhere, you should see it as a red flag. A reputable company will have a contingency plan and will be transparent about it.

#5: What are the Panels’ Key Performance Metrics for My Home?

This question will move the conversation away from generic information about the brand to specific technologies that separate one solar panel from another. The installer will have to prove that he or she isn’t selling a “one size fits all solution” but is acting as an energy consultant. It also shifts the conversation toward technologies that will impact performance. That way, the installer can tailor his or her recommendations to what’s specific to your situation.

Installers need to be aware of how your location, surrounding environment, roof orientation, and array layout can influence performance and panel selection. They must know about other important specifications (such as efficiency, temperature coefficients, and degradation).

They must also be aware of other options with regard to cell technology and layout. Watch out for any vague claims (such as “high quality panels”) without offering any details. You also want to avoid installers who aren’t able to justify why a panel will be a good fit for your home’s unique condition.
