Questions to Ask a Solar Company Before Choosing an Installer

Updated

Knowing the right questions to ask a solar company can help you compare installers with confidence and avoid surprises later. This page explains what to ask about licensing, quotes, equipment, contracts and long-term support for solar panel installation. It is educational only and is not financial, tax, legal or engineering advice.

What it is

Questions to ask a solar company are the things a homeowner may want answered before agreeing to a solar panel installation. They cover who will do the work, what equipment will be used, how the system is designed, and what happens after it is turned on.

Good questions fall into a few groups: credentials and insurance, the written quote, equipment and warranties, permits and utility connection, contract and payment terms, and service after installation. Asking in the same order of each company makes the answers easier to compare.

Solar is a long-term home decision that involves high-voltage electricity and roof work. Clear answers, in writing, are a useful way to understand what you are really being offered.

How it’s traditionally been approached

Many homeowners have traditionally started by collecting several quotes, often after a mailer, an online search, a neighbor's recommendation or a visit from a salesperson. Comparing more than one proposal is a common way to see how designs and terms differ.

Some people rely on word of mouth, local reviews and references from past customers. Others check licensing records with their state or local licensing board and ask about insurance before going further.

Payment has also been approached in different ways: paying cash, using a loan, or signing a lease or power purchase agreement. Each has different responsibilities, terms and long-term effects, so reading the full contract matters whichever route you consider.

How the right solar installer may help

The right solar installer may help by walking through your questions patiently, looking at your roof, shade, electrical panel and energy use, and explaining their design in plain language. A visit generally includes a site assessment, a conversation about your goals, and a written proposal you can take time to review.

Helpful questions may include: Are you licensed and insured in my state? Who does the installation, your own crew or subcontractors? What equipment is proposed and what warranties cover it? Who handles permits and utility interconnection? What happens if the roof needs repair later? How is the system monitored and who do I call for service?

You may also ask how the system behaves in an outage, since grid-tied systems generally shut down unless designed with storage or backup. Ask what is and is not included in the quote, and how incentives are handled. Confirm any incentive details with the IRS or a tax professional, your state energy office and your utility before signing, because programs change.

The bigger picture

Choosing a solar company can feel like a big step, with money, your home and your sense of security all involved. Taking time to ask questions, compare written quotes and sleep on the decision may help you feel more settled and less pressured.

Many people value solar for the preparedness and independence it can bring, and that peace of mind often grows when you understand what you are buying.

Keep in mind

  • Pricing, savings, production and payback vary by home, location, utility and equipment, and should come from a written quote rather than a verbal estimate.
  • Be cautious with high-pressure sales, door-to-door tactics and "sign today" deadlines, and read the full contract before signing.
  • Solar and battery work should be done by licensed, insured professionals following local codes, permits and utility interconnection rules; never attempt DIY wiring.
  • Federal, state and utility incentives and net metering rules change, so confirm current details with the IRS or a tax professional, your state energy office and your utility.

Frequently asked questions

What are the most important questions to ask a solar company?

Start with licensing, insurance, who will actually do the installation, and what is included in the written quote. Then ask about equipment, warranties, permits, utility connection and service after installation. Getting the answers in writing makes them easier to compare.

How do I know if a solar company is legitimate?

Check that they hold the required license in your state and carry insurance, and ask for local references. You can verify licenses with your state or local licensing board. Be careful with companies that use pressure tactics or are unwilling to put things in writing.

Should I get more than one quote for solar panel installation?

Many homeowners find it helpful to compare several written quotes. Designs, equipment, warranties and contract terms can differ even for the same home. Ask each company the same questions so the comparison is fair.

What should I ask about solar contracts and financing?

Ask whether the offer is a cash purchase, loan, lease or power purchase agreement, and what each means for ownership, responsibilities and ending the agreement. Request the full contract and read it completely before signing. A tax professional or attorney can help you understand the terms.

Will my solar system work during a power outage?

Not necessarily. Grid-tied systems generally shut down during an outage unless they are designed with storage or backup capability. Ask the installer exactly what your system would and would not power.

What should I ask about maintenance and support after installation?

Ask who handles monitoring, repairs and warranty claims, how to reach them, and what happens if the company changes or closes. Also ask what roof or workmanship coverage exists. Solar maintenance, repair and monitoring providers may also be an option later on.
