How To Choose a Solar Company

Installing solar panels can reduce your electricity costs and benefit the planet by reducing your carbon footprint. When evaluating if a solar provider is right for you, consider these key factors.

Check Licensing

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

Read Customer Reviews

Check review sites like the Better Business Bureau (BBB), TrustPilot, and Google Reviews to see customer feedback about local solar companies. Detailed reviews can help you assess a company's reliability and customer service. Use caution with providers that have very few reviews or mostly negative ones.

Compare Multiple Quotes

Call 3–5 solar companies for free, itemized quotes. A quote should describe all costs and specify the solar equipment included. Reviewing multiple quotes helps identify the best option that fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Going solar can help decrease your energy expenses. Be sure to evaluate these aspects when determining the cost and value of solar panels.

  • Research federal and state tax credits: There’s a 26% federal tax credit available for the full cost of solar systems until 2032. Many states also provide incentives. The credits can add up to significant savings for solar buyers.
  • Compare system purchase options: Solar panels may be paid for outright or financed over time with loans or leases. Check key financing details like annual percentage rate (APR), payment schedule, fees, and ownership implications when choosing to finance solar panels.
  • Look into utility rebates: Local power companies may offer additional rebates to encourage homeowners to install solar panels. Check the qualification criteria and rebate values with your local utility provider to find out what your savings could be.

Net metering is a power purchasing policy that allows solar energy system owners to receive bill credits or payments for the amount of energy they put back into the grid. It's available in most states and is a great way to reduce energy costs.

Of course. Solar panels are independent of the Island Lake grid 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.
