Why Go Solar?
Cost Savings: Lower your monthly energy bills and see significant long-term savings on energy costs.
Environmental Impact: Reduce your carbon footprint and contribute to a cleaner, more sustainable planet.
Energy Independence: Generate your own electricity, protecting your business from rising energy prices and outages.
Increased Property Value: Enhance your property's appeal and market value with a solar installation.
Government Incentives: Take advantage of tax credits, rebates, and financing options that make solar more affordable.
Financial Incentives & ROI
Solar transforms your roof into a revenue-generating asset. By utilizing the Federal Investment Tax Credit (ITC) and MACRS accelerated depreciation, businesses can significantly offset upfront costs and achieve rapid payback.
Beyond tax advantages, solar provides a hedge against rising utility rates, lowering long-term operating expenses and immediately increasing your property's Net Operating Income (NOI).

Frequently Asked Questions
Yes, installing solar panels incorrectly may void your existing roofing warranty, but working with experienced professionals ensures your warranty remains protected. To avoid this, we coordinate directly with your roofing manufacturer to ensure we follow the attachment method they require. We usually use "overburden" contracts to keep your original roofing warranty intact.
The real-world ROI for most commercial systems is within 3–7 years by combining the 30% federal Investment Tax Credit (ITC), Modified Accelerated Cost Recovery System (MACRS) depreciation, and immediate monthly utility savings. The electricity generated after the payback period is essentially free for the rest of the system's 25-year lifespan.
To determine if your roof can handle the additional weight of a solar array, we conduct a professional structural engineering audit before installation, giving you confidence before the project begins. Most modern commercial roofs are well-suited to handle the additional solar load of approximately 2.5 to 6 pounds per square foot. If extra support is needed, we offer lightweight solutions such as ballasted systems or thin-film solar membranes, which avoid heavy concrete blocks and roof penetrations while still delivering reliable performance.
If the roof leaks under the solar panels, our systems are designed with "walkways" and modular racking that allows technicians to access the membrane without dismantling the entire array. If your roof is over 15 years old, we typically recommend restoring or replacing it first to ensure long-term performance and protect your solar investment.
The solar panel installation will not disrupt your daily business operations because most of the work is on the roof, so your staff and customers inside the building will not be affected. The only disruption you’ll experience is a scheduled 4 to 8-hour window for the final electrical connection to the grid, ensuring a smooth and reliable transition to solar power.
The Financial Path to Ownership
Below is a clear overview of , so you know exactly what to expect.payments, rebates, and available tax benefits
1. A Clear Look at Pricing
For your solar installation, payments are made directly to Green Attic Roofing according to the contract schedule, with clear milestones including a deposit, progress payments, and a final payment after inspection and permission to operate (PTO).
- All utility rebates and tax incentives are provided directly to you, rather than to Green Attic Roofing.
- We handle the paperwork and applications, but you receive the funds directly.
2. Naperville Electric Utility Solar Rebate (Utility Rebate)
What it is: Naperville Electric Utility pays homeowners for installing a qualifying solar system.
How it works:
- After the system is installed, inspected, and PTO is granted, we submit the required rebate documentation on your behalf.
- Naperville Electric Utility issues the rebate payment directly to you.
Typical timeline: Rebates are typically issued within a few months after PTO, depending on the utility’s processing timeline, providing timely financial returns on the system investment.
3. Illinois Shines (REC Incentive)
What it is: Illinois Shines pays you for the renewable energy your system produces, based on the final approved system size.
How you get paid:
- Incentive payments are provided across a five-year period.
- Payment timing aligns with the Illinois Shines program schedule.
- The incentive amount is secured once your system is approved.
Our role: We handle the entire Illinois Shines application and coordination for you.
4. Benefits of Commercializing the System
Commercialization means the system is officially placed into service and recognized as an income-producing asset for tax purposes.
This allows you to:
- Claim business-related solar tax benefits
- Take advantage of the depreciation on the system
Note: This is an administrative step only and does not change how the system operates or how the property is used.
5. Federal ITC (30% Tax Credit)
What it is: A federal incentive that provides a 30% tax credit calculated from the total cost of the system
How it works:
- Directly reduces your tax liability
- Claimed when filing your taxes
Note: If the full 30% tax credit isn’t used in the first year, the remaining balance can be carried forward to offset taxes in future years.
6. Depreciation (MACRS)
Because the system is used for commercial purposes, it qualifies as a depreciable business asset, allowing additional tax write-offs over time.
If depreciation cannot be fully utilized in the first year, the unused amount may be carried forward to reduce taxable income in future years.
