Benefits of Solar Energy

Solar energy offers multiple perks. Let's look at a few of them.

  • Better energy independence: Solar panels can keep your home powered through emergencies and blackouts, giving you additional security. You can use your solar energy anytime with an optional battery storage system.
  • Lower energy bills: Generating some or all of your own electricity will spend less on electricity long-term.
  • Reduced carbon footprint: Using clean solar power lowers your dependence on fossil fuels, which release greenhouse gases that damage the environment.

How To Choose the Best Solar Company in Joliet

The price and effectiveness of solar panels often rely on which company installed them. Make your choice based on the following crucial aspects.

Licensing and Training

In Illinois, the state Commerce Commission regulates distributed generation energy contractors, including home solar installers. Check for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), one of the solar industry's most reputed trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in Joliet

Different solar panel types look and perform differently. Monocrystalline panels cost more than other options, but they generate the most power. Polycrystalline panels provide a lower price point but produce less power. 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 accessories, such as battery storage and electric vehicle (EV) chargers, will increase your overall costs. However, they might make your solar system more efficient and convenient to use. Not all solar contractors offer these extras, so look for a provider that installs them if it's a priority for you.

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

Solar Panel CostAverage Cost
Solar Monocrystalline$1,248
Solar Polycrystalline$974
Thin-Film$569
Solar Battery$799
Solar Home EV Charger$2,996

Financing Solar Energy in Joliet

Solar contractors use multiple different financing options to increase your savings and lower your costs. Though some providers offer unique payment plans, the most common are power purchase agreements (PPAs), cash payments, solar loans and solar leases. We suggest making a cash payment 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 have full ownership of your system and can apply for solar incentives to minimize 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 enjoying energy bill savings and solar incentives. However, you’ll spend more in total due to accruing interest. Solar leases allow you to use 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. Look for companies that offer multiple payment plans to find the right fit for your wallet.

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

The IRS allows you to claim a 26% federal tax credit on your new solar panels, so long as you purchase it before 2032. Municipal authorities and utilities might also offer their own financing programs, rebates, and incentives that could save you more money.

Frequently Asked Questions About Solar in Joliet

How much money could I save by going solar in Joliet?

On average, Joliet homeowners shell out around $1,156 per year on electric bills. Once you repay your solar array, you could reduce your costs by $702.66 for every kilowatt you produce.

Is solar energy widely available in Joliet?

Yes, solar energy is spreading quickly in Joliet. Some homes already use solar power on-site or through utility grids, and they're backed by a state solar economy with 5513 job opportunities and counting.

Will a solar PV system raise my Joliet home worth?

Yes, new solar systems lead to higher property values according to the National Renewable Energy Laboratory (NREL.) Homeowners could project a $20 property value increase for each dollar they save on energy. Therefore, $600 in energy savings could increase your home's value by $12,000.

How can I assess my home's solar potential?

To determine your home's solar readiness, nothing substitutes for a comprehensive quote from a local solar provider. However, you can use the PVWatts tool for a simple solar viability estimate based on public data, including local weather and topography, system size, tree cover, and panel efficiency.

What's the average solar system size in Joliet?

A typical Joliet solar home utilizes a 6.5-kW panel array, but you might need a larger system if your energy needs are more demanding. Solar professionals will evaluate your property's power usage and roof shading to suggest the proper system for you.

How long does it take to pay back a solar loan in Joliet?

The average payback period for a solar loan in Joliet is 18.7 years. By paying off extra principal each month, you can shorten the payback period and own your system faster.

How are a solar lease and PPA different?

Choosing a leasing option means your solar installer will handle panel maintenance while you make fixed monthly payments. PPAs 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 "buy out" of the contract for a fee.
