How To Choose a Solar Company

Putting solar panels on your roof could cut your electricity payments while helping the environment by reducing your carbon footprint through renewable energy use. Key considerations when researching local solar installers are as follows.

Check Licensing

Confirm that your solar installer is properly licensed. This help guarantee that the work is done correctly using current installation best practices. In Illinois, the state Commerce Commission issues licenses to distributed generation energy contractors, including solar installers.

Read Customer Reviews

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

Compare Multiple Quotes

Get free, detailed quotes from at least three solar companies. The quotes should describe all costs and identify the solar parts included. Looking at several quotes can help you find the option that best fits your budget.

Ask About the Warranty

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

Evaluate Financing and Incentives

Solar energy can help reduce your electricity costs over time. When evaluating solar panel's cost and value, be sure to factor in these considerations.

  • Look into utility rebates: Some energy providers may provide additional rebates to motivate homeowners to install solar panels. Check the qualification rules and rebate amounts offered by your local electric provider to determine the possible savings.
  • Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states offer incentives, too. The credits can lead to substantial savings for solar buyers.
  • Compare system purchase options: Solar panels can be purchased upfront or financed through a loan or lease. Check important financing details such as payment schedule, fees, annual percentage rate (APR), and ownership implications when financing your solar system.

Frequently Asked Questions About Solar in Columbia, 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 water heating system.

With home solar energy, you can save money on your energy bill, lower your home's carbon footprint, and be better prepared if there's an outage to the local grid.

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 Columbia, your best time to install solar panels is in the spring and fall.

Your payback period is the time to achieve an ROI on your solar panels. It will vary based on the average sunlight in your area, the rate your utility charges per kilowatt of power, and their rated capacity. Columbia gets quite a bit of sunlight per day, so an average payback period could last up to 16.0 years per 5 kW of capacity.

The answer ultimately depends on your specific situation. You'll be eligible for a federal tax credit of up to 30% of the system's cost, as well as state or local incentives depending on where you are. As for insurance, you'll need to inform your insurance company about your new solar panels. Your premium may increase due to added property values, but you'll have peace of mind if a covered event happens to the system.

The most common types of home solar panels in Columbia 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. Ask your local provider about the types of solar panels they work with.
