Benefits of Solar Energy

Solar energy has numerous advantages that will enhance your home for years to come.

  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Better energy independence: Adding a battery backup or storage system lets you have dependable energy during grid outages and storms.

How To Choose the Best Solar Company in Caseyville

The cost and efficiency of solar panels often rely on which company installed them. Consider each of these criteria in your business search.

Licensing and Training

In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including solar contractors. You should also visit a company's website to learn about its private accreditations. Two of the most recognized are the PV Installation Professional and Solar Heating Installer certificates, backed by the North American Board of Certified Energy Practitioners (NABCEP). Some companies don't publish this information online, so you should also ask your estimator about them.

Cost of Solar Panels in Caseyville

Your solar modules' style will affect how much power you can generate. Monocrystalline panels are among the highest quality and perform the best but cost the most. Polycrystalline panels generate less, but they're a great traditional option for low budgets. Thin-film panels are excellent for non-traditional roof shapes and cost the least, but don't work well for large residential installations.

You can also add electric vehicle (EV) chargers and battery backup systems. These will increase your total installation cost, but they can increase your solar system's performance. Not all solar companies include these add-ons, so look for a contractor that installs them if it's crucial for you.

Generally speaking, it costs about $18,800 for a five-kilowatt solar array in Caseyville. This table lists more specific prices for different solar panel types and system components in your area.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,234.29
Solar Polycrystalline$962.74
Thin-Film$562.83
Solar Battery$789.94
Solar Home EV Charger$2,962.29

Financing Solar Energy in Caseyville

Solar companies use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are solar leases, solar loans, power purchase agreements (PPAs) and cash payments. We advise paying with cash or using a solar loan for the highest return on investment (ROI). Cash payments require a hefty sum up-front, but you’ll pay the least long-term by avoiding interest. You’ll also own your system and can apply for solar panel incentives to reduce your total costs. Solar loans are another solid option if you don’t want to make a big initial investment. You can pay for your system in installments while still benefiting from energy bill savings and solar incentives. However, you’ll pay more in total due to accruing interest. Solar leases allow you to pay a monthly fee to rent your panels, while a PPA lets you pay a variable rate based on only the energy you use. We generally don't recommend these options since you won't own your system and are disqualified from solar incentives, but they might be appropriate in particular circumstances. Look for installers that offer two or more payment plans to find the right fit for your financial needs.

The table below lists the average payback periods for different capacities of solar systems in Caseyville.

You can claim a 26% federal solar tax credit from the IRS for new residential solar systems purchased before 2032. Additionally, local governments and utilities may have their own rebates and financing plans that could reduce your total cost even more.
