How To Choose a Solar Company

Installing solar panels can reduce your electricity costs and help the environment by reducing your carbon footprint. When deciding if a solar provider is a good fit for you, consider these key factors.

Check Licensing

It's imperative that your solar installer has the proper licensing. This helps ensure that the work is done correctly using the most up-to-date installation methods. In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including solar installers.

Read Customer Reviews

Check TrustPilot, the Better Business Bureau (BBB), Google Reviews, and other review sites to see what past customers have to say about local solar companies. Detailed reviews on these platforms can help you assess a provider's reliability and customer service. Be wary of companies with few or mainly poor reviews.

Compare Multiple Quotes

To find a solar installer that works with your budget, get free, detailed quotes from 3–5 providers. The quotes should list all costs as well as all solar equipment included. Comparing several quotes helps you identify the best value.

Ask About the Warranty

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

Evaluate Financing and Incentives

Installing solar panels can help decrease your electric bills over time. When weighing the total price and value of solar panels, be sure to consider these factors.

  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to total system costs is available through 2032. Many states also have incentives. These credits offer substantial savings for solar customers.
  • Look into utility rebates: Local power companies may have extra rebates to incentivize homeowners to go solar. Review the qualification rules and rebate amounts with your local provider to calculate your potential savings.
  • Compare system purchase options: Solar panels can be purchased upfront or financed over time with loans or leases. Confirm key financing details like payment schedule, annual percentage rate (APR), fees, and ownership implications when financing solar panels.

Cost of Solar Installation in Decatur

The cost of solar panels varies based on your system's capacity and the technology being used. The typical Decatur solar array has a capacity of 6.3 kilowatts. Homeowners in the area should expect to pay around $3,760 per kilowatt; the average Decatur homeowners spends roughly $16,565 on a new solar system after accounting for federal tax breaks. (Some homeowners prefer to lease solar panels to lower upfront costs.) A personalized quote from a local solar provider will account for factors such as the capacity, panel type, and size of the planned system, and should include costs for preliminary work, labor, and permit fees.

Frequently Asked Questions About Solar in Decatur, IL

A solar photovoltaic (PV) array can generate power to run any electric system or appliance in your home. If you don't want to use solar power for your entire home, you can install a solar water heating system.

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

Absolutely. Decatur 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.

Your installer can give you an estimate of what your energy bills will look like after you install solar panels. Generally, your energy bills will decrease significantly because you'll be using energy from the sun for free, instead of buying energy from the utility company. The average annual savings in Decatur amount to $1,076.

You might be pleasantly surprised at how quickly you can get a return on investment from your solar panels. The sun shines frequently in Decatur, meaning your payback period could last 15.4 years per 5 kW of capacity on the high end.

The specific types of maintenance you need will depend on the type of panels you're using. Regardless of type, you should inspect your panels for damage and clean them regularly. Many solar contractors in the Decatur area offer low-cost maintenance plans to help you keep your panels healthy and make the most of your system.

Although solar energy is an ideal option for many, it might not be ideal for homeowners in wet, dark areas. In these cases, you could consider other forms of renewable energy, such as wind or geothermal power, as a primary source. It is also important to speak to a qualified installer to determine if their solar system is compatible with the climate and environment of your area. Even if you choose a different form of renewable energy altogether, you'll still lower your emissions and could still qualify for distributed generation or other money-saving programs.
