How to Choose a Solar Company
Get multiple quotes and compare equipment, warranties, and total cost rather than monthly payment alone. Confirm that the installer holds the required Illinois licenses and carries proper insurance, and ask whether installers are certified by the North American Board of Certified Energy Practitioners. Ask about who performs the installation, whether subcontractors are used, and how long the company has operated in Illinois.
Evaluate financing carefully. Buying a system outright usually delivers the greatest long-term savings, while leases and power purchase agreements reduce upfront costs but may offer lower total returns. Be sure you understand how incentive payments are handled.

Battery storage is becoming more popular as homeowners seek backup power during outages. Commercial rooftop solar on warehouses is expanding along the I-80 and I-55 corridors.

Frequently Asked Questions
How much can solar save a Joliet homeowner?
Savings depend on system size, energy usage, roof orientation, and incentives. Many homeowners see meaningful reductions in electric bills, with payback periods shortened by Illinois incentive programs.
Do solar panels work in winter?
Yes. Panels produce less energy on short winter days and when covered by snow, but they operate efficiently in cold temperatures, and annual production is what matters most.
Will solar increase my home's value?
Owned solar systems are often viewed favorably by buyers because they reduce future energy costs. Leased systems require a transfer process during a sale.
Questions to Ask a Solar Installer
Before you commit, a short list of well-chosen questions can reveal a great deal about any provider. Consider asking the following during your first conversation:
- Do your own employees install the system, or do you use subcontractors?
- Which panel and inverter brands do you recommend, and why?
- How do you handle City of Joliet permits and ComEd interconnection?
- What production guarantees and workmanship warranties do you provide?
- How are Illinois Shines incentive payments handled in my contract?
A solar system is a long-term investment, so it is worth taking the time to compare installers carefully. Reputable companies will answer these questions openly and put key commitments in writing.
