Roof Leasing
Your commercial roof works. You earn.
Greenion leases your industrial or commercial roof, builds a PV system — and pays you a secured annual rent. No broker. No intermediary. We use the space ourselves.
Submit inquiry nowNo broker
We build the system for ourselves — as operator, not intermediary. Your contract is directly with Greenion.
Everything from one source
Planning, permits, construction, insurance, operations and maintenance — we take full responsibility.
Investors involved
Your roof becomes part of a real Greenion project, in which investors can participate via the VB Token marketplace.
