It was just missing the right business model.Dover calls the untouched roof on apartment buildings the “naked rooftop.” Owners had zero reason to install solar because they’d get zero financial benefit. And tenants couldn’t install it themselves. So the whole market was stuck.Ivy Energy flipped the entire equation by building a platform that makes solar a new revenue stream for the building owner — not a charity project for tenants. The magic is their software layer, something Dover describes as the “easy button” that tracks energy production, energy use, utility bills, and every transaction between the owner and the tenant. In other words, a virtual grid inside each community.And it’s not just bookkeeping. It’s defensible, transparent financial settlement that regulators trust and tenants benefit from. Owners install solar, tenants keep a slice of the savings, and owners pocket the rest. Profit. Every year. No more split incentives. No more naked rooftops.The wildest part? Investors realized they could install solar, run it for a year, boost the building’s NOI — and then sell the property at a higher valuation. In some deals, that means an instant return before factoring in any long-term cash flow.Ivy’s model is simple: SaaS fees per unit, plus a planning product that uses their massive dataset to help investors deploy capital smarter across their entire portfolio. And the market is huge — 27 million renter households, with more than half viable for on-site energy.They’ve already scaled to 400 communities and 60,000 households, and they’re moving fast through channel partners instead of trying to educate every owner one by one.What’s next? Dover wants Ivy to become the transaction engine for shared energy communities — not just solar, but EV charging, storage, and anything that touches the building’s energy ecosystem. And he’s building the team to get there, hiring people who treat the mission like an inevitability.If you want to understand how one software layer can open wide gigawatts of clean energy on buildings that were previously untouchable, give this episode a listen.
