Benefits of Solar Energy

Solar energy provides multiple advantages. Here are some highlights.

  • Reduced carbon footprint: Using clean solar power means you're less dependent on fossil fuels, which emit harmful greenhouse gasses.
  • Lowered energy bills: Solar panels let you generate your own energy to power your home, lowering your periodic electricity costs. You can eliminate your bills completely if you go off-grid. Plus, a significant amount of states offer net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Better energy independence: Adding a battery backup or storage system lets you have dependable energy during storms and grid outages.

How To Choose the Best Solar Company in St. Clair

The more thorough your company investigation is, the better your solar panels will ultimately function. Here are some key items to consider while searching for a solar provider.

Licensing and Training

In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including solar contractors. You should also visit a company's website to learn about its private certifications. Two of the most prestigious are the PV Installation Professional and Solar Heating Installer certificates, awarded 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 St. Clair

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power and generally have the highest quality. Polycrystalline panels produce less power, but start at a more budget-friendly price point. Thin-film panels work well for small projects like RVs and sheds, but they're not ideal for larger installations due to their low performance.

Additional system add-ons, such as battery storage and electric vehicle (EV) chargers, will increase your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar company includes these extras, so look for a contractor that installs them if it's a priority for you.

A majority of St. Clair homeowners choose solar systems designed for five kilowatts (kW) of electrical capacity. These systems run about $18,800 to install, considering both materials and labor. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,234
Solar Polycrystalline$963
Thin-Film$563
Solar Battery$790
Solar Home EV Charger$2,962

Financing Solar Energy in St. Clair

Choosing the optimal financing plan will influence your overall solar system cost and potential savings. Common payment options include power purchase agreements, leases, loans, and cash payments. We recommend 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 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 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 fluctuating rate based on only the energy you use. We generally don't recommend these options since you will not have ownership of your system and are disqualified from solar incentives, but they might be appropriate in specific circumstances. Ask each installer you're evaluating about the payment plans it offers. A team member can help you determine the most suitable 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 home solar systems purchased through 2032. Extra incentives may be available through local governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in St. Clair

How much energy and money could I save per year by switching to solar?

On average, St. Clair homeowners pay roughly $851 per year for energy. Once you repay your solar array, you could reduce your costs by $794.37 per kilowatt you produce.

Is solar energy widely available in St. Clair?

Yes, solar energy is spreading quickly in St. Clair. Some homes already generate solar power on-site or through utility grids, and they're fortified by a state solar economy with 5513 jobs and counting.

Will solar energy systems increase my St. Clair home worth?

Yes, solar energy systems will raise your property value. According to the National Renewable Energy Laboratory (NREL), for every dollar you reduce on energy bills, your home value rises by $20. So, if your panels save you $600 per year on energy costs, your property could appreciate $12,000.

What if I live in a heavily-wooded or gloomy

A solar system could still operate in cloudy conditions. Your contractor will orient your panels to capture the most sunlight possible. They might also recommend a back-up power source to keep your system functioning at its best.

What size should my new St. Clair solar system be?

The average St. Clair solar system size is 6.1 kilowatts (kW). However, your final system size depends on your home's electricity usage. Your roof size, surrounding shading, and panel model could also impact your final result. A professional solar installer will consider these factors and determine the right array size for your home.

What is the average payback period for St. Clair solar panels?

Most St. Clair homeowners pay back a solar loan in 16.6 years. You can shorten the payback period by paying off extra loan principal each month.

What's the difference between a PPA and a solar lease?

Choosing a leasing option means your solar installer will handle panel maintenance while you make fixed monthly payments. Power Purchase Agreements differ slightly because you pay based on the electricity you produce.

You don't own the panels with either option, though you can choose to opt out of the contract for a fee.
