Watershed and Lumen Energy are partnering to make onsite solar a more practical business decision across large, distributed portfolios of buildings, helping companies move from planning to operating projects with predictable power costs and measurable emissions reductions.

One of the most common questions we hear from asset management teams considering rooftop solar leases is: "What happens after the panels are installed?" It's a smart question—especially when you're managing a portfolio of properties and need clarity on long-term responsibilities, ongoing site access, and what to expect from your solar developer partner. The good news? When you lease your rooftop to a solar developer through a rooftop leasing agreement, the developer takes on virtually all operational responsibilities. Your role is minimal, and the ongoing requirements are clearly defined upfront. Here's what you need to know.

Learn exactly what physical changes solar installations make to commercial roofs, how modern mounting systems work, and how Lumen Energy ensures safety and compliance throughout your rooftop leasing project.

If your building is insured by FM Global, rooftop solar is possible, but only when it meets their rigorous loss prevention standards. From roof assemblies to fire protection and wind uplift, FM’s Data Sheet 1-15 outlines what’s required—and what’s not allowed.

In the latest episode of The Pulse by GRESB, host Reid Morgan sits down with Peter Light, CEO & Co-founder of Lumen Energy, to break down the economic and operational realities of deploying on-site renewables across large commercial property portfolios.
