How To Choose a Solar Company

Adopting solar power lets homeowners reduce utility bills while helping the environment by reducing your carbon footprint using clean energy. If you’re deciding whether to go solar, consider these key factors for choosing an installer.

Check Licensing

Confirm that your solar installer is properly licensed. 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 residential solar contractors.

Read Customer Reviews

Check the Better Business Bureau (BBB), TrustPilot, Google Reviews, and other review sites to see what past customers have to say about local solar companies. Detailed reviews can help you evaluate a provider's trustworthiness and customer service. Stay away from companies with few or mainly poor reviews.

Compare Multiple Quotes

Get free, detailed quotes from three to five solar companies. The quotes should list all costs and identify the solar parts included. Comparing several quotes can help you find the best value for your budget.

Ask About the Warranty

Top-notch solar installations should include strong workmanship and performance warranties. A workmanship guarantee covers installation defects, such as poor wiring, cracks in the panels, or poor alignment. A performance warranty guarantees a minimum energy output. Comprehensive warranties show that a solar company believes in its work.

Evaluate Financing and Incentives

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

  • Compare system purchase options: Solar panels may be paid for outright or financed over time through leases or loans. Review all terms when financing, such as annual percentage rate (APR), payment schedule, fees, and ownership implications.
  • Research federal and state tax credits: There’s a 26% federal tax credit available for total solar system costs until 2032. Many states also provide incentives. The credits can add up to significant savings for solar buyers.
  • Look into utility rebates: Local power companies may have extra discounts to motivate homeowners to install solar panels. Review the eligibility criteria and rebate amounts with your local provider to calculate your potential savings.

Frequently Asked Questions About Solar in Mundelein, IL

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

There are a number of benefits to home solar energy. You can save money, qualify for tax benefits, and reduce emissions. With the right storage equipment, solar panels can also give you additional energy security and offer some protection from power outages.

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

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 Mundelein, 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.

You might be pleasantly surprised at how quickly you can get a return on investment from your solar panels. The sun shines frequently in Mundelein, meaning your payback period could last 18.4 years per 5 kW of capacity on the high end.

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 help the environment and could still qualify for distributed generation or other money-saving programs.

Solar panels are on par with other forms of renewable energy. They have low maintenance costs and today's systems can work in a variety of conditions.
