Home solar power might seem like such a major decision, you might not know what questions to ask when just starting out. Every solar panel installation is a unique project with a different design, price, and performance needs. Even if you know how solar works, or this isn’t your first time with a home solar panel system, you might have a lot of questions. Going solar means committing to a product with a 25-year or longer lifespan. You’re right to want confidence before making any type of commitment.

20 Questions to Ask a Solar Installer
To achieve the best possible experience when you go solar, let’s play a game of 20 questions that you can ask at your next solar consultation.
1. What type of solar panels do you install?
One of the most common questions solar companies are asked is, “What type of panels do you install?”
Although having premium panels is certainly a critical aspect of going solar, it’s not so important to get hung up on any specific brands or wattages. Product developments and supply chain factors mean most companies vary the exact panels they sell and install over time.
So long as your installer can promise solar panels 350 watts or higher, with efficiencies of about 20% or more, you can know your home solar system will be made up of premium residential equipment.
2. What solar incentives are available?
Asking your installer about available incentives is important to maximizing the value of your investment. Whether or not you qualify for the federal solar tax credit and other local solar incentives may significantly impact the return on investment of your energy system.
Around the country, solar incentives vary greatly by state and region, with some cities, counties, and utilities offering their own programs, tax credits, tax exemptions, rebates, and more.
3. How long have you been in business?
In recent years, some solar companies have gone out of business Working with an established, experienced solar company could help you avoid picking a company that’s going to go out of business.
A company able to answer all your questions in a helpful way without putting pressure on you is a sign of a partner you’ll be able to work with and depend on for a long time.
4. Do you sell or lease your solar panels?
Before you sign a contract, understanding its details is an absolute must. In the early stages of your home solar project, consider whether you will buy or lease a solar system based on your personal preferences, financial goals, and available options.
Buying means the system is your property and, in most cases, you will experience more significant monthly savings right after installation. A lease or power purchase agreement, such as Palmetto’s LightReach Energy Plan, will give you solar power from a home system with no upfront cost and manageable monthly payments.
5. Do you offer financing options?
Unless you’re able to pay for your panels upfront or are leasing them, you may need to finance your through a loan. While you are always welcome to explore your own financing options, many reputable solar installers will bring their own programs into the conversation.
By working with a company with multiple financing options, you are more likely to find a solar loan structured to fit into your budget that can unlock your long-term savings on electricity.
6. What do your warranties cover?
You will likely have multiple solar warranties (product, performance, installation) associated with your energy system.
Before signing on the dotted line, talk to your installer about exactly what each of these warranties covers, how long the coverage periods are, and if you can extend the policies during the lifetime of your solar panels.
7. What if a part of my system breaks?
Along with warranty coverage, you should talk to your installer about the likelihood of system damage and what repair or maintenance procedures will be, even if solar panel maintenance is typically infrequent.
If you’re covered by a maintenance and monitoring plan, your installer will have a dedicated customer service team that can field your request and repair the part as soon as possible, ensuring your system will be back up and running without excessive time offline.
8. Can I add more solar panels later?
There are many reasons why your energy demand may increase after installing solar panels, like purchasing an electric vehicle or growing your family. If you anticipate you may want to expand your solar energy system in the future, talk to your installer about this possibility and what an upgrade may look like.
Depending on system setup and available space, it may be a better idea to oversize your system initially rather than add panels later. Or, your installer may make expanding easier by designing a microinverter-based solar system.
9. How long is the installation process?
Any salesperson can throw out an empty promise, but a company that sets an installation timeline (and has the past projects to prove it) is more likely to deliver a good end result. When talking to your solar installer, ask them about the anticipated installation schedule.
Although they may not be able to tell you a precise interconnection date during your initial conversation, reputable companies should be able to provide a breakdown of your solar installation timeline, including permitting, equipment delivery, and actual construction.

10. Do you have a customer referral program?
If your installer has a referral program, it’s a strong sign they are used to delivering good customer experiences. As the best advocates for any company are its customers, many solar companies will compensate those who refer new business in bill credits or cash.
11. Can you explain the total cost of a system?
If a solar contractor gives you a price and doesn’t explain how they arrived at that number, it’s a red flag you may not be getting the best deal possible. Although the average cost of solar panels varies across the country, the total price of any solar energy system can be broken down into hard and soft costs, including expenses associated with hardware, permitting, labor, and business overhead.
12. Should I install a string inverter or microinverters?
There are advantages and disadvantages to string inverters and micro-inverters. As every home solar project is different, talking to your installer about how each technology relates to your unique property can help you maximize your system performance and return on investment.
13. When will my system pay for itself?
If you purchase or finance your solar energy system with a reputable solar installer, they should be able to forecast an approximate break-even point at which your system will have “paid for itself” in savings.
In general, solar panel payback periods average somewhere between 7-10 years, depending on your location, the size of your system, and many other factors. A solar installer should be able to break down the expected performance of your system as it relates to the price of electricity in your area over time.
14. How much will my electric bills be after going solar?
Honest installers will tell you that you still pay an electric bill once the panels are up and producing electricity. Although some advertisements may stretch the truth to say that your panels will completely wipe out utility costs, in reality, your electricity bills after going solar will still exist, but should be lower (especially with net metering).
Ask your installer about utility company service charges or fees that will still need to be paid. In most cases, you will be billed for utility transmission and grid upkeep. The seasonality of your solar power production may also impact your monthly electric bills.
15. How do I track my solar panel performance?
Today, most solar panels are installed with smart components that report system performance directly to a digital landing page. The Palmetto App, for example, allows you to track your solar panel performance alongside your electricity consumption (with a supported meter).
16. What happens when my system reaches the end of its lifespan?
Even though it may be 20-30 years or more into the future, asking your installer about the end of your system's lifespan can help you avoid unwanted surprises later on.
Solar companies that plan to be around for decades are sure to have an answer for you when you ask about the decommissioning process. Critically, the end of your contract may differ if you are buying or leasing your system.
17. Do you offer any special discounts? (Senior, military)
If you are a senior or a member of the armed forces, you may be eligible for discounts with some solar installers. At the same time, some companies don’t provide point-of-sale discounts for customers and instead try to deliver the lowest prices possible to all customers.
18. What other products do you sell? (Generators, EV chargers, home security, etc.)
Going solar can be a great time to also electrify your home with a heat pump or other efficient, electric appliances, install an EV charger, add battery storage, or replace your roof. Combining projects could save you time and money, especially if you use the same company, and let you stretch your solar electricity farther.
19. What makes your company different from others?
When weighing your solar options, you should feel free to open up the discussion and allow installers to explain exactly why they deserve the job. Although any company hoping to stay in business will inform you they are the best option, few installers have the tools, resources, and reputation to show it. A professional solar expert should want to give you all the info you need rather than stick to a sales pitch and make you feel forced into a decision.
20. Can I take my time and think about it?
In a high-pressure sales scenario, you may start to feel a solar installation company is pushing you to sign a contract right there, right now. If you feel rushed, asking for some time to make your decision will quickly show whether or not the company is acting in your best interest or is simply out to get your money.
Occasionally impending policy changes mean you need to rush, but even with those caveats, a reputable company should be happy to do follow-up calls and help you feel confident in your choice.
