How To Choose a Solar Company

Going solar can be a great way to save money on electricity costs and help the planet 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

Confirm that your solar installer is properly licensed. This ensures that the work is done correctly using the most up-to-date installation methods. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including solar contractors.

Read Customer Reviews

Check review sites like the Better Business Bureau (BBB), TrustPilot, and Google Reviews to see feedback from past customers about local solar companies. Detailed reviews can help you assess a company's dependability and level of service. Use caution with providers that have hardly any reviews or mostly negative ones.

Compare Multiple Quotes

Call three to five solar companies for free, itemized quotes. The quotes should explain all costs and list the solar equipment included. Reviewing multiple quotes helps you find the most cost-effective option for your budget.

Ask About the Warranty

Quality solar installations should have strong workmanship and performance guarantees. A workmanship warranty covers any installation defects (such as poor alignment, cracks in the panels, or poor wiring), 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

Solar energy is great for helping 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 upfront or financed over time through loans or leases. Confirm all terms when financing, such as payment schedule, fees, annual percentage rate (APR), and ownership implications.
  • Research federal and state tax credits: A 26% federal solar tax credit on total system costs is available through 2032. Many states also offer incentives. These credits provide substantial savings for solar customers.
  • Look into utility rebates: Local utility companies may offer additional rebates to encourage homeowners to adopt solar panels. Check the qualification criteria and rebate values with your local electric company to find out what you could save.

Frequently Asked Questions About Solar in Warrenville, 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 energy, you can recoup the cost of the system over time, lower your home's carbon footprint, and gain additional energy independence.

It depends on your home's location and the kind of panels you plan to use. Since there's a moderate amount of snowfall in Warrenville, your best time to install solar panels is in the spring and fall.

Yes. Warrenville uses an even 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 payback period is the time to earn a net profit from your solar panels. It will vary based on their rated capacity, the average sunlight in your area, and the rate your utility charges per kilowatt of power. Warrenville gets quite a bit of sunlight per day, so an average payback period could last up to 16.2 years per 5 kW of capacity.

Net metering is a power purchasing policy that allows solar energy system owners to get paid 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 ideal for some in dark or wet areas, the latest generation of equipment and energy storage systems could increase your property's solar viability enough where you could 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.

Some frequently-used types of home solar panels in Warrenville include thin-film, polycrystalline and monocrystalline. Monocrystalline panels are balanced and efficient, while polycrystalline and thin-film panels pair good performance with greater upfront value. Talk with your local provider about which solar panels they work with.
