Requesting a solar quote is easy. Getting one you can trust and compare is harder, and it starts with asking the right questions. This checklist covers what to ask a solar company about its business, equipment, pricing, financing, and installation, plus a short list of questions to answer about your own home first. Use it whether you are in California, Texas, Florida, or Illinois, and you will walk into every conversation knowing what a good answer sounds like.
Solar Questions at a Glance
| Topic | The key question | Why it matters |
|---|---|---|
| The company | Are you licensed, insured, and established locally? | Your system will need service for 25 years or more |
| Equipment | Which panels and inverters do you use, and why? | Equipment drives performance and warranty coverage |
| Cost | What is the total price, itemized, before and after incentives? | Lets you compare quotes on equal terms |
| Financing | Who owns the system and who keeps the incentives? | Ownership changes your savings |
| Installation | What is the timeline from contract to switch-on? | Permits and utility approval add time |
| Your utility | How will net metering affect my savings? | Export credits vary by state and utility |
| Your home | Is my roof ready, and how much power do I use? | Accurate inputs mean an accurate quote |
Why Ask These Questions Before You Request a Quote
A solar quote is only as accurate as the information and honesty behind it. A quote built from a satellite photo and a guess at your usage can change the moment a designer looks closely at your roof. Asking questions up front protects you in two ways:
- You get a sharper number. When the installer knows your real usage, roof, and goals, there is less padding for unknowns.
- Your quotes become comparable. Two quotes are only comparable when they rest on the same assumptions, so you can see real differences in equipment and price.
- You spot weak companies early. A good installer answers directly. Evasive answers are an answer too.
Questions to Ask a Solar Company About Its Business
Experience, Licensing, and Reputation
| Question | What a good answer looks like |
|---|---|
| How long have you been in business? | A clear track record, not just a new brand name |
| How many systems have you installed near me? | Specific local numbers and examples |
| Are you licensed, bonded, and insured? | A license number you can check, plus proof of insurance |
| Do you have NABCEP-certified staff? | Yes, with a certified professional involved in the installation |
| Can you share recent customer references? | Several recent references, offered without hesitation |
| Will you still be around to honor the warranty? | Financial stability and a service team in your area |
Rules differ by state, so see our guide to licensed solar contractor requirements by state before you rely on any license answer. For a full framework on picking between companies, read how to choose a solar company.
Who Actually Does the Work
- Do you use your own crews or subcontractors for the roof and electrical work?
- How do you make sure subcontractors meet your quality standard?
- How much experience do you have with my specific utility’s interconnection process?
Subcontractors are not a red flag by themselves. The key is that the company is open about it and stays responsible for the result.
Questions to Ask About Solar Equipment and Warranties
Panels and Inverters
| Question | Why ask it | What to listen for |
|---|---|---|
| Which panel brand and model will you install? | Quality and warranty vary by manufacturer | Named brand and model, not “standard panels” |
| Why did you choose this equipment for my roof? | Shows whether the design fits you or just what is in stock | A reason tied to your roof, shade, and goals |
| What is the panel efficiency and wattage? | Helps you compare output per panel | Efficiency around 20% and wattage near 400 watts is typical |
| What is the degradation rate? | Panels lose a little output each year | 0.5% per year or less |
| Microinverters or a string inverter, and why? | Affects shading performance and monitoring | A reason that fits your roof layout |
For a closer look at how efficiency affects your decision, see our guide to solar panel efficiency.
Warranties and Service
| Warranty type | What to ask |
|---|---|
| Product warranty | How long does it last, and what does it cover for panels and inverters? |
| Performance warranty | What output is guaranteed, and for how many years? |
| Workmanship warranty | How long does the installer cover the installation, including roof leaks? |
| Service | Who do I call if something goes wrong, and how fast do you respond? |
Typical benchmarks are about 25 years on panels and at least 10 years on workmanship. Our breakdown of what a solar warranty covers explains each type in detail.
Questions to Ask About Cost, Incentives, and Financing
Pricing and Savings
- What is the total installed cost, and is it itemized?
- What is the cost per watt before and after incentives?
- How much will I save in year one and over the life of the system?
- What annual utility rate increase are you assuming in your estimate?
- What is my expected payback period?
- Does the price include permits, interconnection, and monitoring?
The utility rate assumption is worth extra attention. A quote that assumes very fast rate hikes can make savings look bigger than they will be.
Incentives
- Which federal, state, and local incentives apply to me, and who claims them?
- Do you handle the paperwork for rebates and programs?
- Is the quote showing the price before or after incentives?
Tax rules for solar have changed, so confirm current eligibility with the installer and a tax professional. Our guide to solar incentives beyond the tax credit covers programs that can still lower your price.
Financing and Ownership
| Question | Why it matters |
|---|---|
| Is this a cash, loan, lease, or PPA offer? | Each option changes your cost and savings |
| Who owns the system? | The owner typically keeps the incentives |
| Do payments stay fixed or rise over time? | An escalator can change the math in later years |
| What is the loan rate and total repayment? | A low monthly payment can hide a high total cost |
| What happens if I sell my home? | Transfers and payoffs differ by option |
Compare your solar financing options in California side by side, and if a no-money-down offer comes up, read how a solar PPA works and what it costs per kWh first.
Questions to Ask About Installation and Timeline
| Question | What to listen for |
|---|---|
| What are the steps from contract to switch-on? | A clear sequence: design, permits, install, inspection, utility approval |
| How long will each step take? | A realistic timeline, with permits and utility approval included |
| Do you handle permits, inspections, and interconnection? | Yes, as part of the price |
| What if the work runs late or equipment is unavailable? | A written plan, not a shrug |
| What if a leak or roof issue appears later? | Workmanship coverage that includes roof penetrations |
To see what a normal schedule looks like, read what to expect during solar installation and how long going solar takes.
Questions to Ask About Batteries, Net Metering, and Your Utility
Where you live shapes the economics as much as your roof does. Ask every company to explain these points for your own utility:
- How do net metering or export credits work where I live, and how are they reflected in my savings estimate?
- Do I need a battery for backup power, and how much would one add to the quote?
- Can I add panels or a battery later, and how would that work with this design?
- What happens to my system during a grid outage?
| State | Net metering snapshot (verify current rules) |
|---|---|
| California | NEM 3.0, so exports earn lower credits and batteries matter more |
| Illinois | Supply-only model, with programs such as Illinois Shines |
| Texas | No statewide mandate, so it depends on your retail provider |
| Florida | Utility rules apply, so confirm the credit your utility offers |
Read how net metering works and how it has changed and whether you need a battery with solar before you request a quote.
Questions to Ask Yourself Before You Request a Quote
Some of the most important answers come from you, not the installer. Gather these first:
| Question for you | What to do | Helpful guide |
|---|---|---|
| How old is my roof, and does it need work first? | Check its age and condition, since panels last 25 to 30 years | Is your roof ready for solar |
| How much shade does my roof get, and which way does it face? | Note trees, chimneys, and roof directions | Is my home good for solar |
| How much electricity do I use in a year? | Pull 12 months of bills and find your annual kWh total | What size solar system do I need |
| Do I want backup power during outages? | Decide before the quote so a battery is priced in | Do I need a battery with solar |
| Who is my utility, and what is my rate plan? | Know your plan so the savings math is accurate | Net metering explained |
| Do I own my home, and how long will I stay? | Your timeline affects payback and your financing choice | Selling a house with solar panels |
| How do I want to pay? | Pick cash, loan, lease, or PPA before comparing offers | Solar financing options |
What a Good Solar Quote Should Include
A good quote answers more questions than it raises. Check that every quote you receive includes:
- The panel brand, model, and number of panels.
- The inverter or microinverter brand and model.
- The total system size in kilowatts.
- Expected annual production in kWh, and the degradation rate.
- Total cost before and after incentives, ideally as a cost per watt.
- Estimated yearly savings, with the utility rate increase it assumes.
- Financing details: loan rate, term, monthly payment, and total repayment.
- Warranty details for equipment and workmanship.
- A roof layout showing where the panels will go.
Once a quote is in hand, the next step is the fine print. Use our list of solar contract questions to ask before you sign.
Red Flags to Watch For
- Pressure to sign today or a discount that “expires” tonight.
- A price with no itemization or only a monthly payment.
- Claims of “free” solar with no explanation of who owns the system.
- Vague answers on licensing, warranties, or who does the work.
- Savings estimates that depend on very high utility rate increases.
You should always feel free to take time to decide. For more on vetting a company, see our guide to finding the best solar installers near you.

Frequently Asked Questions
What questions should I ask a solar company?
Ask about their licensing and experience, the exact equipment and warranties, the itemized price before and after incentives, who owns the system, the installation timeline, and how net metering will affect your savings.
What should I know before buying solar panels?
Know your annual electricity use, your roof’s age and shading, your utility and rate plan, and how you plan to pay. Those inputs let an installer size and price a system accurately.
What is the most important question to ask a solar installer?
Ask for a fully itemized price and who keeps the incentives. That single answer reveals the real cost, the ownership structure, and how transparent the company is.
Does it cost anything to get a solar quote?
Reputable solar quotes are free and come with no obligation. Preparing first does not change the price of the quote. It helps you get an accurate, comparable number.
How many solar quotes should I get?
Two or three quotes is a sensible number. Make sure each is built on the same information about your usage and goals, so you are comparing real differences.
Should I check my roof before requesting a solar quote?
Yes. Panels last 25 to 30 years, so it helps to know whether your roof can last that long. If it is near the end of its life, reroofing first avoids paying to remove and reinstall panels later.
What makes one solar quote better than another?
A better quote is more transparent and accurate, not just cheaper. It names the equipment, states expected production, lists every incentive, and shows the net price line by line.
Is it okay to take time before signing a solar contract?
Yes. A reputable company will give you time and follow up without pressure. If you feel rushed, that is worth noting.
