Benefits of Solar Energy

Solar energy provides several advantages that will enhance your home for years to come.

  • Lowered energy bills: You can dodge the expensive cost of grid-tied power by creating some electricity right where you use it. Plus, many states offer net metering which can allow you to sell your unused energy back to credit part of your bill.
  • Reduced carbon footprint: The sun is a highly abundant clean energy source, meaning you can minimize or conquer your home's dependence on fossil fuels.
  • Better energy independence: Adding a solar battery storage system lets you have dependable energy during storms and grid outages.

How To Choose the Best Solar Company in Thornton

Choosing a company is the first step toward an effective and valuable solar energy system. Make your choice based on the following vital factors.

Licensing and Training

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

The kind of solar panels you purchase decides how much energy you can generate. Monocrystalline panels and high-quality and cost more but give you the best performance. 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 the best for large residential installations, but they are excellent accessories for non-traditional roofs.

Additional components, such as battery storage and electric vehicle (EV) chargers, will raise your overall installation costs. However, they might make your solar system more efficient and convenient to use. Not every solar company provides these additional features, so look for a provider that sells them if it's a priority for you.

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

Solar Panel CostAverage Cost
Solar Monocrystalline$1,198
Solar Polycrystalline$935
Thin-Film$546
Solar Battery$767
Solar Home EV Charger$2,876

Financing Solar Energy in Thornton

Solar providers use multiple different financing options to lower your costs and increase your savings. Though some providers offer unique payment plans, the most common are power purchase agreements (PPAs), cash payments, solar leases and solar loans. Most solar experts recommend a cash payment or using a solar loan. Cash payments demand a large up-front sum, but they help you avoid paying interest, grant you system ownership, and qualify you for cost-saving solar incentives. Solar loans have the same benefits, though you'll pay more in total due to interest and fees. Like a home or car loan, you'll pay a set monthly rate with potentially $0 down. Solar leases allow you to rent your panels for a fixed monthly rate, while PPAs let you pay only for the energy you use, akin to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. We suggest working with an installer that offers multiple financing options. Speak with each consultant about what's available, and get more than one estimate for the best odds of keeping within your spending limits.

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

A 26% federal solar tax credit applies to new home solar systems purchased through 2032. Further incentives may be available through local governments, usually in the form of rebates and special financing programs.

Frequently Asked Questions About Solar in Thornton

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

On average, Thornton homeowners shell out approximately $1,156 per year for energy. Once you repay your solar array, you could save $707.72 per kilowatt you produce.

How common is solar energy in Thornton?

Yes, solar energy is readily available in Thornton. A growing number of local homes are already using solar power on-site or through utility grids, and Illinois has about 5513 jobs forming its solar economy.

Will a solar PV system boost my Thornton home value?

Yes, a solar PV system will boost your property value. According to the National Renewable Energy Laboratory, 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 dark or heavily-wooded

A solar system could still work well in cloudy conditions. Your contractor will orient your panels to capture the most sunlight possible. They might also recommend a battery backup system to keep your system working at its best.

How can I assess my property's solar suitability?

One common way to find your home's solar viability is by using PVWatts. This free, powerful tool considers local weather and topography, panel efficiency, system size, and tree cover to determine how much electricity your array could generate. However, it's not a substitute for consulting with a local solar installation company, who can create a full estimate with the most updated data.

What's the average solar system size in Thornton?

A typical Thornton solar home has a 6.4-kW panel array, but you might need a bigger system if your energy needs are higher. Solar contractors will evaluate your property's energy consumption and roof shading to recommend the right system for you.

What's the difference between a PPA and traditional financing?

A PPA is an agreement between you and your provider. They install, own, and maintain the panels, and you purchase the generated electricity from them for 10–25 years. There will usually be options to buy out early to own your system and extend the agreement.

In contrast, solar loans can come from local banks, the government, installer and specialty lenders. You'll need to pass a credit check to qualify for most of them. While the upfront costs are greater, and you'll be responsible for maintenance, you'll also have total ownership and can apply for many more benefits.

Should I get quotes from multiple Thornton solar companies?

Yes, we suggest requesting free solar quotes from three or more companies. You should thoroughly read each quote and compare prework scope and costs, equipment costs, warranty details, labor fees and financing options. Ensure each quote includes an itemized financial plan and includes your expected payback period.
