When it comes to commercial electricity costs, demand charges can drive higher bills. Unlike standard energy charges, which are based on total electricity consumption, demand charges focus on how much power your business pulls at once. If you're not managing them wisely, they can make up 40–50% of your bill.
So, what exactly are demand charges, and how can solar energy help mitigate them? Let’s break it down—with a little help from a car analogy.
Think of your business’s electricity usage like a car:
Here's how it works:
For commercial businesses, this can drastically impact your monthly bill—especially if peak demand happens during working hours
Solar power can offset a significant portion of your energy costs, but demand charges require a different strategy:
That’s why a strategic approach to power use is essential.
Reducing demand charges is about controlling when and how power is used. Here are smart ways to keep your demand charges in check:
Demand charges can drive up commercial electricity costs, but with the right approach, they don’t have to be a roadblock. When businesses pair solar with storage, demand response strategies, and smart scheduling, they can cut peak demand and save thousands over time.
At ilumen Solar, we dive deep into commercial energy bills to ensure your solar investment works for both energy savings and demand charge reduction. Want to see how much you could save? Get in touch with us today—let’s map out a solar strategy that works for you.
Mike Kelly had been interested in solar for years but was consistently told it wasn’t possible due to his cedar shake roof, which posed installation risks.

Jim Hahn had three key priorities for his solar project: work with a local company, maintain an aesthetically pleasing installation, and stay within budget. ilumen Solar was the right fit, not only because of our detailed, collaborative approach but also because of our commitment to custom residential solar solutions that balance function and design.
Unlike larger, national solar installers, our personalized attention ensured that every element of Jim’s system—from the conduit run to the electrical upgrades—was thoughtfully planned and executed with his goals in mind.
This project involved more than just a standard solar installation. Jim’s home needed a new roof, which was covered under insurance and completed by our roofing partner, Expert Roofing. Additionally, we identified that his main breaker panel was outdated and a known electrical hazard, requiring an upgrade to ensure compliance with current safety codes.
One of the most important aspects of the project was the conduit run. Initially, the plan was to route the conduit through the basement ceiling using a ceiling chase. However, once installation began, it became clear that this approach was far too labor-intensive and cost prohibitive. After reassessing, we worked with Jim to find a better solution—running the conduit along the basement wall, under the deck, and over to the meter. This new approach was both aesthetically clean and budget-friendly, making it the ideal alternative.
As we moved forward with the project, we discovered that significant electrical upgrades were necessary. This can sometimes be a tough conversation, but our team took the time to clearly explain the necessity of each upgrade, ensuring Jim understood why these changes were needed for the safety and efficiency of his solar system.
Transparency was key in this process. By keeping Jim informed at every step and ensuring he saw the long-term value of the improvements, we were able to move forward with full alignment.
The outcome was a seamless solar installation paired with a brand-new roof, leaving Jim highly satisfied. Every detail—especially the aesthetics—was carefully executed to match both Jim’s vision and our team’s high standards.
Here’s what Jim had to say about working with ilumen Solar:
We were impressed by the professionalism and transparency of Zach's team throughout our residential solar installation last year. The project involved more complexities than we initially anticipated, requiring us to gain a deeper understanding of various aspects before signing off and during the execution.

For Eric Gannon and his family in Barrington Hills, IL, the goal was simple but challenging -install solar panels on their barn in a way that preserved the aesthetics of their beautiful property. However, achieving this required a creative, customized solution that blended functionality with visual appeal.
This project presented a unique set of challenges, from structural limitations to the preservation of the property’s aesthetics. Each obstacle required a tailored solution to meet Eric's needs while exceeding expectations.
The original plan was to install solar panels on the barn, located approximately 250 feet from the main house. However, after careful analysis, the barn was deemed unsuitable for the solar array due to structural concerns. This led to a creative pivot: a low-profile ground-mounted array was installed 350 feet from the house in a nearby field, tucked out of sight.
To further ensure the system's discretion, the tilt of the panels was adjusted to 20 degrees—10 degrees lower than the standard 30-degree angle typically used. This adjustment reduced the visibility of the array while maintaining its efficiency, creating a solution that blended functionality with visual appeal.
Connecting the ground-mounted solar array to the home required running electrical lines across 350 feet of the property. Traditional trenching was not an option due to its potential to disrupt the landscape and damage recently installed brick pavers on the patio. To address this, directional boring was utilized—a technique that allowed pipes to be installed underground without disturbing the surface. This method preserved the integrity of the property while ensuring a clean and efficient installation.
Another potential challenge was shading caused by tall grass and brush near the array, which could impact its performance over time. To mitigate this, commercial-grade ground cover was installed at no additional cost to the client. This proactive measure not only ensured optimal system performance but also made long-term maintenance easier. The ground cover was strategically placed around the front and east side of the array, minimizing vegetation growth and enhancing the overall aesthetic.

At ilumen Solar, we believe that providing a seamless and transparent experience for our clients begins long before we install your solar panels. One of the key ways we do this is through comprehensive site inspections, conducted before we even provide a quote.
You might be wondering: Why do we go to the trouble of doing a site inspection up front? Why not just offer a quote based on basic information and move forward? The answer is simple: We do this because it's more beneficial to you, our client. It allows us to provide an accurate, reliable, and tailored proposal from the very start, ensuring there are no surprises along the way.
One of the most important aspects of installing solar panels is ensuring that they’re placed on a structurally sound roof that can handle the weight and configuration of the panels. To ensure the highest level of precision, we use drone technology to conduct a detailed flight over the roof. This drone flyover allows us to map out the roof in 3D, capturing all of its dimensions, angles, and any potential obstructions.
By using this technology, we can:
With this data, we don’t just give you a generic quote – we create a proposal that’s custom-tailored to your home and specific needs.
A solar installation is more than just panels on a roof. To ensure everything works seamlessly, we must assess your electrical system. During our site visit, we inspect the location of the meter, service panel, and any existing electrical conduits to determine how the solar system will connect to your home’s power grid.
Why is this so important?
Picture 1 – potential code violation with the meter inaccessible, but depends on the jurisdiction and the utility company
Picture 2 – Outdated breaker panel (Pushmatic), which are no longer up to code and need to be replaced
Picture 3 – Cold, Hot, and Gas pipes need to be bonded at the hot water heater to be up to code and pass a solar inspection
While many solar companies conduct their site visits after you’ve signed a contract, Ilumen Solar takes a different approach. By doing a thorough inspection before providing a quote, we ensure that we’re accounting for any hidden costs that might arise, such as the need for electrical upgrades or repairs to bring your home’s system up to code.
Other companies may offer you a shiny proposal that looks great on paper but may later surprise you with additional charges once they conduct their site inspection. At that point, you could be facing unexpected expenses for things like electrical upgrades or changes to the layout. Unfortunately, these issues often come up only after you’ve committed to the project.
At Ilumen Solar, we believe in full transparency from the very beginning. By addressing any potential issues during our site inspection, we can:
Our goal is to make your solar journey as smooth and stress-free as possible.

Is your business ready to make the switch to solar? ilumen Solar, one of the leading commercial solar companies, is here to help you design a cost-effective and efficient solution.
Liberty Self Storage, a commercial storage facility in Crystal Lake, IL, sought to reduce operating expenses by integrating a solar power installation into its business operations. As a forward-thinking company, they wanted a solution that would offer financial savings and environmental benefits while addressing the unique challenges of their high-traffic location.
Energy costs can significantly impact operational budgets for commercial facilities. Liberty Self Storage approached Ilumen Solar, a leading commercial solar power company, to design and install a system that would help reduce utility bills and improve financial stability. Their goal was to take advantage of available incentives to ensure a quick return on investment while optimizing long-term savings
The deciding factor for Liberty Self Storage was the financial appeal of the project. By leveraging Federal Tax Credits, Illinois solar incentives, and ComEd rebates, the client saw the potential for a fast payback period. ilumen Solar provided a clear breakdown of these benefits, giving Liberty Self Storage the confidence to move forward.
Additionally, ilumen’s expertise in handling site-specific challenges and customizing solutions to meet unique needs set them apart from other commercial solar installers.
Every solar project comes with its challenges, and this was no exception. Liberty Self Storage raised concerns about potential tampering with solar equipment due to the high volume of customer traffic on-site.
To address this concern, ilumen Solar installed special locks on the inverter and disconnects to prevent tampering. The inverter, which converts solar energy into usable electricity, and the disconnects, which safely shut off the system for maintenance or emergencies, are critical components of any solar installation. By securing these with locks, ilumen Solar ensured the equipment remained protected from unauthorized access while staying fully accessible to authorized personnel when needed. This straightforward yet effective solution provided peace of mind and maintained system functionality.
Reliable system monitoring is a critical component of solar installations, but Liberty Self Storage’s office was too far from the equipment to establish a direct internet connection.
To solve for this, ilumen Solar customized a cellular internet plan to bridge the gap, staying within budget while providing reliable connectivity for monitoring the system’s performance. This solution ensured real-time tracking of energy production and consumption, giving Liberty Self Storage confidence in their solar investment.
Additionally, midway through the project, the location of the solar equipment needed to be changed. This adjustment required additional trenching and an extended conduit and wire length. ilumen Solar addressed the issue through a small change order, ensuring the project remained on schedule without compromising quality or functionality.
The completed solar panel installation has been a resounding success for Liberty Self Storage. The client is already experiencing significant financial benefits, including:
The system not only meets but exceeds expectations in terms of performance and aesthetics. The installation looks professional, and the client is thrilled with the outcome.

A solar benefit called “net metering” is NOT going away in 2025, but it is adjusting, under state law.
Net metering is a benefit for solar users. Under Illinois law, investor-owned utilities (ComEd, Ameren, MidAmerican) are required to offer net metering for renewable energy generation (such as solar power). This means anytime the solar panels a consumer installs generate more power than the household needs, that consumer can sell that excess electricity back to the utility and receive electric bill credits. The utility will only charge the solar customer for the net amount of electricity consumed, plus any other fixed delivery charges (such as the customer charge, standard metering charge, delivery service cost adjustment).
It used to be difficult for solar users in Illinois to sell excess power back to the utility, but in 2008 legislation took effect that simplified the process.
On Jan. 1, 2025, the net metering benefit is being reduced for Illinois residents who decide to install solar panels on their homes. Two important points:
Net metering currently gives 1:1 per kilowatt-hour credits on these parts of your electric bills: Supply, Delivery and taxes and fees.
If you have solar panels on your home now: You are guaranteed this current version of net metering for the lifetime of your system (defined, under net metering regulations, as 30 years from the date the solar installation received permission to operate). That means you will continue to have this full benefit on all three sections of your bill.
If you install solar panels after Jan. 1, 2025 a few significant changes:
To summarize, this new system means customers who install solar panels after Jan. 1, 2025 will receive 1) a larger benefit upfront; 2) a reduced net metering benefit throughout the lifetime of the system; and 3) credits that never expire.
If you are interested in understanding the financial details of a project under the new Illinois net metering adjustment, we recommend obtaining multiple quotes from reputable installers. Since every solar installation is custom built, the best way to find out is by obtaining a formal design and quote.
If you currently have panels on your home, the way you are compensated for net metering will not change.
If you install panels after Jan. 1, you will continue to save on your utility bills, but the net metering benefit will be lower.
However, every project now qualifies for the ComEd Distributed Generation rebate, which in most cases levels out any long term net metering reduction.
A transition like this is typical in states as they achieve higher levels of solar adoption–and Illinois in recent years has enjoyed a solar boom.
A reduction in the net metering benefit was planned in state law as far back as the Future Energy Jobs Act of 2016. The utilities would have preferred this change to happen much sooner than 2025, but consumer advocates successfully extended full net metering benefits for years.
Changes to Net Metering policies can spur battery installations paired with solar, and in states like California under Net Metering 3.0, often times, it doesn’t make sense to install solar without batteries.
However, in Illinois, solar does not need to be paired with batteries to reap the benefits of partial net metering. We’re finding minor adjustments, such as scaling back the system size, adjusting the layout to include multiple azimuth roof faces, and meticulous analysis of historical consumption can achieve financial results similar or better to full retail net metering.
At the start of 2025, Illinois net metering adjusts from 1:1 “full retail” to supply only “partial” net metering. While long term financial benefits may hinder slightly, the ComEd DG Rebate significantly improves financials in the first year. When applying the DG Rebate and adjusting the system size and layout, don’t be surprised if the financials actually improve!

As the world shifts toward renewable energy, states like Illinois are leading the charge with innovative programs that encourage solar energy adoption. One such initiative is the Illinois Shines program, which plays a crucial role in promoting solar energy installations across the state. This blog will provide an overview of the Illinois Shines program and delve into the concept of Solar Renewable Energy Certificates (SRECs) and how they function.
The Illinois Shines program, originally known as the Adjustable Block Program (ABP), was launched to facilitate the growth of solar energy in Illinois. It aims to provide financial incentives for both residential and commercial solar installations, making solar energy more accessible and affordable for Illinois residents.
SREC stands for Solar Renewable Energy Certificate. It is a market-based instrument that represents the environmental benefits of producing solar energy. For every megawatt-hour (MWh), or 1,000kWh, of electricity generated by a solar energy system, one SREC is created. These certificates serve several purposes:
In Illinois, SRECs are integral to the Illinois Shines program. Here’s how they work:
The Illinois Shines program, coupled with the SREC framework, offers a robust mechanism for promoting solar energy in Illinois. By providing financial incentives and creating a marketplace for SRECs, the program supports both the growth of renewable energy and the economic empowerment of individuals and businesses investing in solar technology. As Illinois continues to expand its renewable energy initiatives, understanding these components will be crucial for those looking to tap into the benefits of solar energy.
ilumen Solar is here for support! As an Approved Vendor for the Illinois Shines program, we are here to consult and manage the process so that you can claim the incentives without all the confusion.

As more homeowners and business owners consider the switch to solar energy, understanding the various factors that affect solar panel installation becomes crucial. One of the most significant aspects is the condition of your roof. In this article, we’ll explore how roof conditions influence solar installation, the types of roofs best suited for solar panels, and what to consider before making the investment.
Roof Age: The age of your roof is a critical factor. Most roofs have a lifespan of 20 to 30 years, depending on the materials used. If your roof is 10+ years old, it’s wise to repair or replace it before adding solar panels. New installations can last 25 years or more and combining the lifespan of both can lead to unnecessary expenses in the future.
Roof Type: Different roof types have varying compatibilities with solar panel systems:
Orientation and Pitch: The orientation and pitch of your roof significantly affect the efficiency of solar energy production. South-facing roofs typically receive the most sunlight, making them ideal for solar installations. However, east- and west-facing roofs can also be viable options with proper adjustments. The pitch of your roof can impact the angle of the panels; steeper roofs may require special mounting equipment to optimize solar exposure.
Shading Issues: Overhanging trees, nearby buildings, or other structures can create shading problems for solar panels. Even partial shading can reduce the efficiency of your solar system. Before installation, it’s crucial to evaluate potential shading throughout the year, not only during peak summer hours, but winter sun hours as well. If shading is a concern, trimming branches is a possible solution. We’re not a fan of removing trees unless necessary, so please refer to a local arborist for consulting on any potential tree removal.
Roof Inspection: If you or your installer are concerned with the age and condition of the roof, we recommend scheduling a thorough inspection with a trusted roofer . A qualified roofer can assess the condition of your roof and identify any necessary repairs or upgrades. As needed, ilumen Solar can recommend qualified and trusted roofers in the area.
Consult Solar Professionals: It’s best to engage with a reputable solar installer in your area to guide you through the process. With the multitude of project details, an experienced solar representative can help you navigate the specifics of your roof relating to the installation.
Insurance Coverage: The Illinois Shines solar program requires all solar owners to include the installation under their homeowner or business insurance. Prior to install it’s important to reach out to your insurance agent about the upcoming project and ensure that the solar installation gets added to your insurance plan.
Squirrels: When it comes to residential solar installations, squirrel activity is something to always have a keen eye for. If squirrels have easy access to the roof via tree branches or bushes, it’s likely they will eventually build a nest between the panels and the shingles. Unfortunately, this can cause serious damage to the installation which can require quite a bit of maintenance to get back online. If you are concerned about squirrels damaging your investment then it would be wise to install a squirrel guard, which is a mesh skirting that can be installed at the base perimeter of the entire solar array.
Roof Replacement After Install: If you’ve already installed solar and you need a roof replacement, your roofer and solar installer can coordinate a tear down/reinstall. If the circumstance is due to storm damage, it’s likely most or all of this expense would be covered by insurance. Otherwise, it’s best to conduct thorough due diligence to avoid this situation after your installation has been completed.
Roof conditions play an important role in solar panel installation and overall long-term production of the project. By understanding the importance of roof integrity, age, type, orientation, and shading, homeowners can make informed decisions about their solar energy investment. Taking the time to prepare your roof can lead to a smoother installation process and greater long-term savings on energy costs.
Embrace the solar revolution, but remember: a solid roof and protection plan is the foundation of a successful solar journey!
