How To Choose the Best Solar Company in St. Clair

The price and efficiency of solar panels often hinge on the provider that installed them. Make your choice based on the following essential elements.

Licensing and Training

In Illinois, the state Commerce Commission licenses distributed generation energy contractors, including residential solar contractors. Solar installers can also earn accreditations from trade groups and standards organizations. The most prestigious ones in the industry come from the NABCEP. Most company websites will prominently display earned credentials, but you should also ask your estimator for more information.

Cost of Solar Panels in St. Clair

The type of solar panels you choose determines how much energy you can generate. Monocrystalline panels and high-quality and give you the best performance but cost more upfront. Polycrystalline panels produce less power, but they're worth it if you want a traditional panel style without the high cost. Thin-film panels aren't meant for large home installations, but they're excellent for small projects like sheds and RVs.

If you'd like to charge an electric vehicle (EV) or use your solar power in cloudy weather, you can pay extra for accessories. By choosing the right components, you can make your panel array more productive and user-friendly. Not every solar provider offers these extras, so look for a provider that sells them if it's essential for you.

You can plan to spend about $18,800 on average for a five-kilowatt solar energy system in St. Clair. Use the table in this section to get an idea of the amount St. Clair solar companies might quote for your specific solar system's price.

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 St. Clair

There are numerous ways to pay for new solar panels, and the right one will lower your costs. A few of the most common options include leases, cash payments, loans, and power purchase agreements (PPAs). We recommend making a cash payment or securing 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 have full ownership of your system and can apply for solar panel incentives to reduce your total costs. Solar loans are another good 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 spend more in total due to accruing interest. Solar leases allow you to pay a monthly rate 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 suitable in certain circumstances. Ask each installer you're vetting about the payment plans it offers. A team member can help you determine the optimal option for your budget.

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

A 26% federal solar tax credit applies to new residential solar equipment purchased through 2032. Extra incentives may be available through city and state governments, usually in the form of rebates and special financing programs.
