- Lucas: If you had solar panels installed in the last couple of years, there's a good chance the company that put them up isn't independent anymore. Private equity has been quietly consolidating residential solar installers, and the numbers are getting large. Luna: I've read that pe backed platforms now account for maybe a quarter of all residential installations. Is that right? Lucas: Close to it. Let's use a concrete example: SolarFlex. That's a platform backed by Apollo Global that went on a buying spree starting in 2023. They've acquired over 30 local installers across the Sun Belt. Luna: What's the typical seller look like in these deals? Lucas: Usually a family-owned business doing maybe 5 to 10 million in revenue, one or two locations, and the founder is tired of managing 40 employees and dealing with permitting nightmares. They're doing fine—growing 10 to 15 percent a year—but they see the writing on the wall: bigger players get better panel pricing and lower financing costs. Luna: So PE comes in and offers an exit. What kind of multiples are we talking about? Lucas: Typically 4 to 6 times EBITDA, but solar installers have lumpy earnings because of weather and policy shifts. A good year might get you 6x; a bad year, maybe 3.5x. SolarFlex was reportedly paying around 5x for well-run shops, with earn-outs tied to retention of the sales team. Luna: That earn-out piece is crucial. Solar sales are relationship-driven. If the lead salesperson leaves, you lose the pipeline. Lucas: Exactly. And that's one of the biggest integration challenges. PE firms try to standardize the sales process—CRM, scripts, financing options—but installers often have a scrappy, local brand that customers trust. Push too hard on centralization and you bleed installers. Luna: Right. So besides sales culture, what other synergies do they chase? Lucas: Procurement is the big one. A single installer buys panels from a distributor at maybe 30 cents per watt. A platform buying 50 megawatts a quarter can negotiate down to 22 or 23 cents. That margin swing alone can boost EBITDA by 200 basis points. Luna: And then there's back-office consolidation—HR, accounting, permitting support. You can centralize that and cut costs. Lucas: But you have to be careful. Solar permitting varies wildly by county. A centralized team can't just copy-paste a permit application from Arizona to Florida. So successful roll-ups run a hybrid model: local installers keep their brand and sales, but back-office and procurement get merged. Luna: That's the playbook. How does Apollo or any PE firm eventually exit these platforms? Lucas: Usually they aim for a sale to a larger strategic—think a utility or a solar financier like Sunrun—or they take the platform public. But the IPO window for solar has been choppy. Some are looking at selling to another PE firm in a secondary buyout. Luna: There's also the policy risk. The federal investment tax credit is set to step down after 2032. That could cool demand. Lucas: It's exactly this kind of operational detail that makes these roll-ups work—or fail. The best sponsors model multiple scenarios: a 30 percent ITC extension versus a 10 percent cliff. Luna: And that's why we dig into these deals every week.

So, back to solar—one of the biggest challenges post-acquisition is managing the supply chain for panels and inverters. In 2024, we saw anti-dumping tariffs on certain imports cause price spikes. A platform that had locked in multi-year contracts with manufacturers like Qcells or Longi were insulated; others got squeezed. Luna: So inventory management becomes a competitive edge. Did SolarFlex get burned? Lucas: They actually did well because Apollo pushed them to sign two-year supply agreements with Korea's Hanwha Qcells. That gave them predictable pricing. Smaller competitors were buying spot and paying 10 to 15 percent more. Luna: That's a real advantage. But it only works if you have the scale to negotiate those contracts. A 30-installer platform can do that; a single shop can't. Lucas: Right. And that's the core thesis of these roll-ups: by combining fragmented local businesses, you unlock procurement and operational efficiencies that the independents can't match. The question is whether the integration costs and cultural friction eat up those gains. Luna: Have we seen any failures? I remember that one platform, SunStreet? They went bankrupt in 2023 after overpaying and not integrating well. Lucas: SunStreet was a cautionary tale. They paid 7x revenue for a bunch of installers in 2021, when multiples were inflated. Then interest rates rose, demand softened, and they had no margin of safety. SolarFlex is more conservative—closer to 5x EBITDA with earn-outs that protect the downside. Luna: What about the exit environment now? With rates stabilizing, are we seeing more strategic buyers? Lucas: There's interest from utilities—especially in states like California and Texas where a big chunk of new capacity is rooftop solar. Also from homebuilders who want to offer solar as a standard option. But the most active buyers are still PE firms looking to build meg-platforms. Luna: So we might see a wave of second-generation consolidation, where SolarFlex sells to a larger player like a kkr backed platform. Lucas: That's likely. And if the ITC gets extended beyond 2032, the whole industry gets a multi-year tailwind. If not, we'll see margin compression and a shakeout. Private equity will be in the middle, trying to consolidate fast enough to build moats before the policy tide turns. Luna: It's an interesting bet. Thanks, Lucas. Lucas: Thanks, Luna. Next week we'll look at private equity's growing interest in waste management—specifically roll-ups of independent dumpster rental companies.
