How To Choose a Solar Company

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

Check Licensing

Verify that your solar installer is properly licensed. This helps ensure that the work is done correctly using current installation best practices. In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including home solar installers.

Read Customer Reviews

Look at review platforms such as the Better Business Bureau (BBB), Google Reviews, and TrustPilot to find out what previous customers have to say about local solar companies. Reviews can give you an idea of a company’s reliability and customer service. Avoid companies lacking reviews or with predominantly negative feedback.

Compare Multiple Quotes

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

Ask About the Warranty

Quality solar installations should come with comprehensive workmanship and performance guarantees. The workmanship warranty covers any installation issues such as poor alignment, poor wiring, or cracks in the panels. The performance guarantee promises a specific energy output level. Strong guarantees indicate that a solar installer has faith in its installations.

Evaluate Financing and Incentives

Solar power can help lower your electricity costs in the long run. When weighing solar panel's cost and value, be sure to factor in these considerations.

  • Compare system purchase options: Homeowners can pay for solar panels upfront or spread out payments over time with a loan or lease. Be sure to confirm key details like fees, payment schedule, annual percentage rate (APR), and what ownership means when financing solar panels.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states also offer incentives. These credits can lead to substantial savings for solar buyers.
  • Look into utility rebates: Some utility companies may provide additional rebates to incentivize homeowners to install solar panels. Check the qualification rules and rebate amounts offered by your local electric utility to estimate the possible savings.

Frequently Asked Questions About Solar in Maryville, IL

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

With home solar panels, you can recoup the cost of the system over time, lower your property's emissions, and be better prepared if there's an outage to the local grid.

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

Yes, you can use home solar energy alongside conventional power sources. In many areas, solar panels are designed to supplement your existing energy sources, so you can reap the environmental benefits and savings of solar energy without having to completely switch over.

Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the rate your utility charges per kilowatt of power, their rated capacity, and the average sunlight in your area. Maryville gets quite a bit of sunlight per day, so an average payback period could last up to 20.3 years per 5 kW of capacity.

Net metering is a type of "power purchase agreement." If your utility or state offers net metering, you can return the solar energy you don't use to the grid. In return, they'll give you a credit on your power bill.

Regarding taxes, the federal government offers a tax credit of up to 30% of the panels' cost. Depending on where you live, you could also claim or apply for state or property tax incentives. For insurance, your monthly premium may be slightly higher because solar panels increase your property's value. You should talk with your accountant or insurance agent for information specific to your case.
