A fixed rate you can underwrite and a structure built to be financeable. Here's exactly how the economics work, including the calculator and an illustrative pro forma.
$0.40 per usable square foot, per year.
Paid monthly, with a 1% annual escalator, for a 20–25 year term. It's a simple, fixed number you can drop straight into an underwriting model: no production assumptions, no variable revenue, no surprises.
A 100,000 sq ft roof generates roughly $40,000 a year, about $1,000,000 over a 25-year term, before the escalator.
Because the project has to be financeable.
The lease rate is set by the lender's Debt-Service Coverage Ratio (DSCR): the cushion between project cash flow and debt payments that lenders require to fund construction.
A higher lease rate looks more attractive at first glance, but it reduces DSCR below the level lenders will accept, which makes the project unfinanceable and means it never gets built. $0.40 is the rate that keeps the project bankable and the income flowing to you for 25 years.

Live, transparent, and based on our standard $0.40 per usable square foot per year.
Illustrative estimate. Actual rates depend on a site inspection: available area, transformer capacity, roof age and condition, structural viability, and interconnection.
An illustrative pro forma.
A representative 100,000 sq ft single-building project. Your actual numbers come from a site-specific analysis.
Term total reflects the 1% annual escalator on a fixed $0.40 base. Figures rounded and illustrative.
How the income builds over 20 years.
Cumulative owner lease income on a representative 100,000 sq ft roof, at $0.40 per usable square foot with a 1% annual escalator. Every bar adds that year's rent on top of the last.
