Question · Q4 2025
Julian Dumoulin-Smith asked about the timeline for battery gross margins to reach the corporate average, considering the evolution of products. He also inquired about the cadence of prepaid lease adoption and its effectiveness in offsetting the impacts of the Section 25D tax credit expiration, both for Enphase's program and market-wide.
Answer
Badri Kothandaraman (President and CEO, Enphase Energy) explained that current battery gross margins are slightly below the corporate average due to tariffs (45% on China cell packs and raw materials). He stated that innovation, particularly the 5th-generation battery with its radically different cost structure, is designed to achieve above corporate gross margins, with new battery generations expected every 18 months. Regarding prepaid leases, Kothandaraman reiterated that the program is in early pilot stages, aiming to replace the pre-25D loan TAM. He expects to have more clarity in the next three to six months and is confident in expanding to more states and gaining market share.
