    Experience can make a difference

    • How many years have they been in business?
    • How many installations have they done?
    • Ask them about their experiences with local permits and inspectors. One common cause of project delays is permits and inspections.

    Check their credentials

    A good way to narrow down your choices is to check the company’s certifications and expertise. Find out more about their previous work and whether they are experienced in setting up systems on types of roofing similar to the one you have.

    For accreditation, the “gold standard” program is the North American Board of Certified Energy Practitioners (NABCEP). Getting a certification from this board requires training in solar installation and clearing a written test– so a certified installer will have a satisfactory amount of knowledge about the job. Do not hesitate to ask for proof of certifications and licenses from the companies you are considering.

    Reviews and client testimonials

    Going through online reviews can give you a good idea of the company’s track record. Type the [company’s name + your state + reviews] in a search engine, preferably Google since they have their own reviews. Take your time to read the experiences people had with the company, during the installation process and after the system has been working for many months.

    Client testimonials are also helpful. See if the company has customer video testimonials. Video testimonials are arguably more authentic and credible than testimonials you read on the company’s website.

    Asking friends, family, and neighbors can also help you shortlist installers. There are over 2 million solar installations across the US. It is very likely that someone you know has used the services of an installation company and can refer you to a reliable one.

    Warranties should include service and parts

    Check what kind of warranties the company is offering, this is a vital factor choosing a solar installer. The service contract may include maintenance policies, performance guarantee of the system, and warranties on the workmanship.

    If there are such warranty policies, go into the details of what exactly is covered and the duration of the warranty. Usually, a good installer is willing to give 5-10 years of warranty on their services. Make sure you read the fine print to avoid disappointment later.

    Most of the hardware like the solar panels, inverters, and racks have a 20-30 year warranty.

    Turnaround time – get an ETA

    With the popularity of solar systems growing, installers often have a lot of jobs lined up. Ask the companies to give you an idea of their schedule and when they can start working on your installation.

    In addition, get an estimate of how many days they will need to get the job done. On average, installing a standard 3-kilowatt system with approximately 20 solar panels takes between 1-3 days or around 75 labor hours. Of course, the exact turnaround time will depend on the type of solar system you want to be installed.

    Customized solutions – one size does not fit all 

    When it comes to solar installations, avoid installers that try to sell you on a “one size fits all” system – because it does not work that way. Instead, find companies that offer customized solar solutions depending on your home and family’s specific requirements. Quality installers will visit your property, check the roof space, understand your budget, and evaluate your recent electricity bills to understand your power needs. They will then suggest the best-suited solar systems.

    Ask questions like whether they will upgrade your property’s electric panel if needed. You can also check if the company is familiar with getting local permits for the installation and if they will do it for you.

    Financing options

    National or local company?

    Often, bigger and well-established companies offer good warranties, maintenance services, and several payment options. Local service providers, on the other hand, tend to have more knowledge about the tax incentives, state rebates, and rules that apply to solar installation in your area. 

    Do they use sub-contractors?

    Get multiple quotes – compare and save

    We suggest that you get quotes from at least 3 companies. You’ll be able to compare prices, products, contracts, and people. Not to mention, you typically save money getting multiple quotes, they compete for your business. Be transparent with them, tell each solar company that you’re getting multiple quotes. You don’t have to mention the names of the other solar installers.

    However, do not let cost be the only factor for choosing an installer for your home. If something sounds inexpensive and too good to be true, it probably is. Installers offering significantly cheaper options might be using low-quality products that will turn out to be costlier in the long run. Try to compare the bids based on similar metrics to make the decision easier for yourself.
