How To Choose a Solar Company

Going solar can be a great way to reduce electricity costs and help the environment by reducing your carbon footprint using renewable energy. Here are some crucial factors to consider when determining whether a solar installer is trustworthy.

Check Licensing

Make sure you hire a licensed solar installer. This ensures that the work is done properly using the most up-to-date installation methods. In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including home solar installers.

Read Customer Reviews

Check consumer review platforms like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see customer feedback about local solar companies. Detailed reviews can help you evaluate a company's dependability and level of service. Use caution with providers that have no reviews or mostly negative ones.

Compare Multiple Quotes

Contact 3–5 solar companies for free, detailed quotes. Quotes should clearly outline all costs and list the exact solar components included. By comparing multiple quotes, you can identify the best value based on your budget.

Ask About the Warranty

High-quality solar installations should have robust workmanship and performance warranties. The workmanship warranty covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output warranty guarantees an energy generation baseline. Strong warranties reflect a solar provider's confidence in its installations.

Evaluate Financing and Incentives

Solar energy can help you lower electricity bills over time. Make sure you consider these aspects when considering the final cost and value of solar panels.

  • Compare system purchase options: Solar panels can be purchased upfront or financed over time with leases or loans. Confirm key financing details like payment schedule, annual percentage rate (APR), fees, and ownership implications when financing solar panels.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states offer incentives, too. The credits can result in substantial savings for solar buyers.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to switch to solar power. Check the requirements to qualify and the rebate values with your local power company to find out what you could save.

Cost of Solar Installation in Frankfort

The cost of solar panels varies based on system capacity and the technology used. The average solar system in Frankfort has a capacity of 6.5 kilowatts. Homeowners in the area should expect to pay around $3,760 per kilowatt; the average Frankfort homeowners spends roughly $16,997 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower their upfront costs.) A personalized quote from a local solar provider will account for things like the capacity, panel type, and size of the planned system, and should include prices for preliminary work, labor, and permit fees.

Frequently Asked Questions About Solar in Frankfort, IL

Generally speaking, a solar photovoltaic (PV) system can be used to power any household appliance or system that uses electricity. In the smallest case, you can use a solar water heater.

With home solar panels, you can recoup the cost of the system over time, lower your home's carbon footprint, and gain additional energy independence.

It depends on where you live and what type of panels you're installing. Since there's a moderate amount of snowfall in Frankfort, your best time to install solar panels is in the spring and fall.

Of course. Frankfort uses an equal mixture of solar energy and conventional power sources. While your panels at home will save you money and lower your home's individual emissions, you'll still benefit from access to the local grid.

Generally speaking, your energy bills will decrease significantly after you install solar panels. This is because you're using the energy you generate for free rather than buying it from your power company. In Frankfort, the average amount someone can save is $904 per year. With net metering programs offered by many utilities, you could ultimately make a profit from your system after the payback period concludes.

Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can return the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.

While solar energy might not be the best option for some in wet or dark areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough to achieve a return on investment. A contractor could also recommend a different primary source of renewable energy like wind or geothermal to boost your generation.

The best type of residential solar panel will depend on your specific needs and goals. Generally speaking, monocrystalline solar panels are the most efficient for homes in Frankfort. However, if lowering cost is your top priority, then you may want to consider thin-film or polycrystalline solar panels. When selecting a solar company, make sure to ask about the brand names and models of solar panels an installer offers and the benefits and drawbacks of each.
