Frequently Asked Questions
- What are Illinois SRECs worth?
- Joliet systems typically generate SRECs valued at $4,000-$10,000 over the 15-year program through Illinois Shines. Sold either upfront (lump sum at install) or annually. Most installers include SREC enrolment as part of the project.
- Is solar worth it in cloudy Illinois?
- Yes — Illinois solar resource is roughly 1,200-1,400 kWh/kW/year, comparable to Germany. With ComEd net metering, SREC payments, and the 30% federal ITC, payback is typically 6-9 years for a Joliet system.
- Do I need a battery in Joliet?
- Battery is optional for grid-tied solar but adds resilience during ComEd outages. Tesla Powerwall 3, Enphase IQ 5P, and FranklinWH all qualify for the 30% federal ITC. Adds $14,000-$22,000 to a typical install.
