Today's Homeowner looks at dozens of datapoints on solar companies to come up with our data-driven rankings. It's not possible for a company to pay for preferential treatment in our rankings. We look at the following key factors in determining who should top our list:
Putting solar panels on your roof could cut your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.
Confirm that your solar installer is properly licensed. This helps ensure that the work is done correctly using current best installation practices. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including home solar installers.
Look at review platforms such as Google Reviews, the Better Business Bureau (BBB), and TrustPilot to find out what previous customers say about local solar installers. Reviews can give you an idea of a company’s trustworthiness and customer service. Avoid companies lacking reviews or with predominantly negative feedback.
Call 3–5 solar companies for free, itemized quotes. A quote should explain all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the most cost-effective option for your budget.
Top-notch solar installations should have strong workmanship and performance guarantees. A workmanship guarantee covers installation issues, such as poor wiring, cracks in the panels, or poor alignment. A performance guarantee ensures a minimum energy output. Comprehensive warranties show that a solar company believes in its work.
Solar energy is great for helping you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.
In Joliet, solar panels cost an average of $3,760 per kilowatt, with an average system size of 6.5 kilowatts. The typical Joliet homeowner spends $17,026 on their solar array after federal tax refunds. An estimate from a local provider will factor in additional information based on your desired system's capacity, size, required preliminary work, and panel type. In some cases, homeowners may prefer to lease solar panels to reduce upfront costs.

A solar photovoltaic (PV) array can generate power to run any electric system or appliance in your home. More specifically, you can install a solar water heating system.
With home solar PV, you can save money on your energy bill, lower your home's carbon footprint, and gain additional energy independence.
It depends on your home's location and the kind of panels you plan to use. Since there's a moderate amount of snowfall in Joliet, your best time to get solar is in the spring and fall.
Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the rate your utility charges per kilowatt of power, the average sunlight in your area, and their rated capacity. Joliet gets quite a bit of sunlight per day, so an average payback period could last up to 18.7 years per 5 kW of capacity.
Yes. Solar panels exist independently from the power grid in Joliet and will continue to generate power even if the grid is having problems. Bear in mind, however, that a solar system without a storage system cannot keep you running through a nighttime outage. Your contractor can discuss some economical options to keep your home's power access reliable through the worst conditions, including battery backups or an emergency generator.
Some frequently-used types of home solar panels in Joliet include thin-film, monocrystalline and polycrystalline. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Talk with your local provider about what kinds of solar panels they work with.
