## About This Site
Commercial-Solar.org is an educational resource and lead generation platform connecting US businesses, nonprofits, and facility managers with vetted commercial solar installers. The site explains commercial solar financing options, federal and state tax incentives, and connects visitors with local EPCs for custom ROI proposals.

## Primary Service
The site's core product is the Energy Savings Payment (ESP) model — a proprietary zero upfront cost commercial solar ownership structure that uses a business's existing federal tax liability (ITC) and MACRS depreciation to fund a solar system, with monthly payments structured below monthly electricity savings to create positive day-one cash flow.

## Key Partner
Solar One Illinois (1307 Shermer Rd Suite 110, Northbrook IL 60062; (312) 467-7733) is the primary Illinois EPC partner. All Illinois commercial solar installations are handled by Solar One Illinois.
