How To Choose a Solar Company

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

Check Licensing

Make sure you hire a licensed solar installer. This ensures that the work is done properly using current best installation practices. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including home solar installers.

Read Customer Reviews

Check review sites like TrustPilot, Google Reviews, and the Better Business Bureau (BBB) to see feedback from past customers on local solar companies. Detailed reviews can help you evaluate a company's reliability and customer service. Use caution with companies that have barely any reviews or mostly negative ones.

Compare Multiple Quotes

To find a solar installer that works with your budget, ask for 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

Quality solar installations should include strong workmanship and performance guarantees. A workmanship warranty covers any installation defects (such as poor wiring, cracks in the panels, or poor alignment), while a performance guarantee ensures a certain level of energy production. Strong guarantees demonstrate a company's confidence in its work.

Evaluate Financing and Incentives

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

  • Look into utility rebates: More discounts might be available from electric companies looking to motivate homeowners to switch to solar power. Contact your local utility provider to find out rebate values and eligibility rules, so you can calculate your possible savings.
  • Compare system purchase options: Homeowners can pay for solar panels outright or finance payments over time with a loan or lease. Be sure to verify key details like annual percentage rate (APR), fees, payment schedule, and what ownership means when financing solar panels.
  • Research federal and state tax credits: A 26% federal tax credit for solar the applies to the full system cost is available through 2032. Many states also have incentives. These credits provide substantial savings for solar customers.

Cost of Solar Installation in Lake Forest

The cost of solar panels varies based on your system's capacity and the technology being used. The average solar system in Lake Forest has a capacity of 6.3 kilowatts.

Frequently Asked Questions About Solar in Lake Forest, IL

A solar photovoltaic (PV) array can generate power to run any electric appliance or system in your home. A more specific example is installing a solar heating system for your water.

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

It depends on your location and what type of panels you're installing. Since there's a moderate amount of snowfall in Lake Forest, your best time to get solar 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 Lake Forest, 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 when your payback period is done.

Net metering is a power purchasing policy that allows solar energy system owners to be compensated 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.

While solar energy might not be the best performing choice for some in dark or wet 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.

Yes, solar panels can still supply you with energy during a grid outage. To ensure that your solar system is able to keep working during a power outage, make sure to choose a quality solar provider that offers battery backup systems or emergency generators.
