Proprietary Energy Savings Payment Model

The Energy Savings Payment Model (ESP) is unique to Com-Sol. helps IL businesses apply to see if they are eligible with Com-Sol. Not all qualify. This model combines benefits from each traditional solar model into a revolutionary hybrid model where the client receives the tax advantages, minimizes the upfront expense, increases the property value, and receives instant energy savings. As the client receives energy savings, Com-Sol shares in a percentage of those savings to help pay down the system’s cost. Com-Sol assumes all risk and maintains the system for free until the system is paid off.

  • Creates positive cash flow from Day 1.
  • No upfront expense, simply pass along the equal value of the tax benefits you would have otherwise paid the Federal government.
  • ​You own outright and don’t share profits with a bank.
  • ​Free maintenance until the system is paid off.
  • Solar equipment increases the value of your company assets.
  • No risk of performance; if it doesn’t produce electricity, you don’t share savings.
  • In the event you sell your facility, Com-Sol contract is freely assignable.


Illinois Commercial Solar Case Studies

Illinois businesses are not just adopting solar energy; they’re leading the way in the renewable energy revolution.

Case Study Batavia Illinois: Suncast Corporation – Innovation in Manufacturing

Solar project in Batavia, IL 60510

Suncast’s $175k savings 1.63 mW Solar Array. and Com-Sol have done two more 1 mW+ projects with Suncast for their facilities

$175k Annual Savings by Year One

This privately owned manufacturing corporation employs 1800+ employees in Batavia and across Illinois. Known for their durable plastic products retailing for Home Depot and the alike, they use quite a bit of electricity. We educated them on our program detailing how much they would save year over year with our proposal. After months coordinating with Suncast and Batavia utility to accommodate their massive array, their 1.6 megawatt system went live in June 2021. This solar system was paid for using the company’s tax liability in conjunction with the Federal Tax Credit and Illinois Smart Inverter Rebate. As a result, the company began saving money as soon as the system was operational in June 2021. They have now contracted Com-Sol to build an additional 1+ megawatt solar assets across all of their facilities taking advantage of the larger tax credit from the Inflation Reduction Act.

Project Stats

  • Solar Capacity: 1.63 mW
  • Installation Date: 2021
  • Annual Savings: $175,000/year
  • Energy Offset: 15% of Electricity Offset by the Sun

Case Study Carol Steam, IL: Packaging Personified

Packaging Personified Carol Steam IL 60116
Founded in 1975, located in Carol Steam, IL this packaging company is a leader in the flexible packaging industry that provide everything from printing, bagging, rollstocking, lamination and more. After realizing they could get a solar system that would offset 20% of their usage without requiring any loan or capital, they immediately capitalized on our financing program and used the federal and state subsidies to pay for their system. They are now cash flow positive from day 1 after turning on the system. This is because 100% project covered are by incentives through our one of a kind program.

Project Stats

  • 14,000 square foot roof
  • 452 kW Solar System
  • Saving $39,488 a year
  • Saving $3,921/month and $901k over 25 years
  • 25 Year Warranty
  • Installation of Battery Storage Systems to Protect Against Outages and Peak Demand Charges
  • Required No Upfront Capital for the System

Solar Economics Example for 60016

For Example, Even in Cold, Rainy, Cloudy Illinois…

50,000 square foot roof top = $1 million in savings over 25 years

100,000 square foot roof = $2 million in savings over 25 years

1.333 = production factor in Illinois for example (if at 180 degree tilt)

1.333 x 700 kw = annual kWh (kilowatt-hour) produce in year = 933

A kilowatt hour is when you add in your supply delivery, taxes, conservatively worth $0.08 = 1 kWh

Supply rate on average = 5.5

Take $0.08 x 933 (annual kwH produced in a year)

= ~$70,000/year in savings

Which = $6,000/month in electricity savings

Or ~$2 million in savings over 25 year warrantied life.

Illinois Commercial Solar Incentives and Savings

Illinois renewable portfolio standard (RPS) has been drafted and it explains that it aims to increase the renewable energy production by 25% by the year 2025. Illinois is rapidly emerging as a leader in solar energy. You can ready about all of Illinois solar incentives and rebates here. These state and utility level incentives and rebates that make solar installations more feasible and financially rewarding for businesses and homeowners alike. Each incentive program, with its unique benefits, collectively contributes to the state’s ambitious clean energy goals.

Below are some highlights.

Solar Renewable Energy Credits (SRECs)

One of the most attractive solar incentives in IL is the state’s Solar Renewable Energy Credit (SREC) Program.

Illinois’ SREC Program is the top reason to install solar in Illinois. It gives solar energy owners the chance to make money for any extra energy their panels generate. Solar system owners in Illinois can generate Solar Renewable Energy Credits (SRECs) based on the energy produced by their solar panels. In Illinois, each SREC is equivalent to 1,000 kilowatt-hours (kWh) of solar energy or one megawatt (MWh). Essentially, whenever a solar array generates a MWh, a corresponding SREC is created.

Owners sell their SRECs in Illinois through a 15-year contract. Larger systems, ranging from over 25.0 kW to 5,000 kW, receive annual payouts over a 7-year period.

Illinois Net Metering

Under the Illinois net metering policy, utility companies in Illinois will credit you with any excess energy your solar system generates. This helps you “zero-out” your annual energy costs. Net metering enables you to collect credits when your solar energy panels are producing more energy than you use. You can then use those credits when your panels produce less than what you need (like during winter months).

Commercial Rebates for ComEd Customers

If you’re a ComEd Utility’s commercial customer, you may qualify for commercial and industrial rebates, which will help you decrease the cost of installing solar considerably.. Commercial solar panel systems that have a total capacity of up to 2,000 kilowatt (kW) qualify for a $250 rebate per each kW. That’s an incredible $25,000 rebate for a 100 kW system!

Federal Solar Tax Credit (ITC)

Thanks to the Inflation Reduction Act, The Federal Solar Tax Credit was increased from 26 percent to 30%. This is considerable for busineseses leveging the ESP program who have tax liability. Instead of it going to Uncle Sam, you can transfer that liablity toward a solar system – a cost reducing asset!

Combined with our proprietary energy savings program we provide Illinois businesses the most compelling solar ownership program out there. Contact us today to learn if our program is a fit for your organization.

Evaluating the Worth of Solar in Illinois

Is solar for business worth it in Illinois? The answer is a resounding yes. The combination of state and federal incentives significantly lowers the initial cost of solar panel installation for industrial buildings.

The Changing Landscape of Solar Energy in Illinois

Illinois, once lagging in solar energy adoption, is now making significant strides. The Climate and Equitable Jobs Act (CEJA) has been instrumental in this turnaround, offering incentives like the Illinois Solar For All and Solar Renewable Energy Credits (SRECs) programs. These initiatives are not just about providing financial incentives; they are about making renewable energy accessible to all and pushing Illinois towards becoming a clean-energy leader.

The state’s extensive network of waterways, including the iconic Mississippi River, the Ohio River, and the Wabash River, forms natural boundaries and critical conduits for commerce. The Illinois Waterway, a pivotal link between the Great Lakes and the Mississippi River, is a cornerstone of the state’s transportation infrastructure. The Port of Chicago connects Illinois to international markets through two main routes: the Great Lakes via the Saint Lawrence Seaway to the Atlantic Ocean and the Great Lakes to the Mississippi River. This global connectivity positions Illinois as a key player in international trade.

For decades, Chicago’s O’Hare International Airport has proudly stood as one of the world’s busiest airports, symbolizing Illinois’ global reach and its pivotal role in both national and international air travel.
