Solar stocks split sharply on Thursday, with Enphase Energy Inc. (NASDAQ:ENPH) surging 15% and SolarEdge Technologies Inc. (NASDAQ:SEDG) jumping 17% while Canadian Solar Inc. (NASDAQ:CSIQ) sank 11% in a lopsided trade. The moves highlight a stark divergence between residential-focused solar plays and utility-scale module manufacturers.
"The lopsided trade in ENPH, SEDG, and CSIQ highlights how three names lumped into the same sector can react in opposite directions when business models diverge," David Moadel, a financial writer, said in a 24/7 Wall St. report. "Residential-focused names are catching a bid while utility-scale module makers face renewed margin scrutiny."
The rally in residential solar was fueled by an update from Enphase showing U.S. sell-through demand rose 21% sequentially, its strongest reading in two years. SolarEdge has also posted six straight quarters of non-GAAP gross margin expansion. In contrast, Canadian Solar’s first-quarter revenue beat was overshadowed by a core gross margin of 12% after excluding a $93 million tariff refund.
The market is rewarding the higher-margin, differentiated products of Enphase and SolarEdge, which serve the U.S. and European rooftop markets. The performance of these companies is being helped by a cooperative rate backdrop, with the 10-year Treasury yield at 4.46%, keeping solar financing math workable for homeowners. Meanwhile, Canadian Solar’s exposure to commoditized utility-scale module manufacturing and pressure from Chinese competitors is being penalized by investors.
A Tale of Two Solar Business Models
The divergence in stock performance reflects the different business models. Enphase and SolarEdge sell higher-margin power electronics, such as inverters, into the residential market. This contrasts with Canadian Solar's utility-scale module business, which is more exposed to commodity dynamics and pricing pressure.
Year-to-date, the performance gap is clear. SolarEdge stock has gained 68% and Enphase is up 49%, while Canadian Solar faces a difficult path with second-quarter margin guidance of 13% to 15% as the benefit of the tariff refund disappears.
Investors will be watching to see if the bid for residential solar stocks holds. For Canadian Solar, the focus will be on whether analysts cut their estimates following the weak margin guidance.
