Topic: TPO financing structures for long-tail installers and market share; 2026 TAM outlook and channel inventory management.
Key points:
Mgmt is in deep discussions with TPO partners to bring lease financing access to long-tail installers, aiming to prevent market erosion. Details expected next earnings call.
Mgmt’s personal view expects a 20% drop in U.S. solar TAM in 2026 (from approx. 4.5 GW in 2025 to 3.5 GW), driven by the 25D expiration, with lease expanding slightly and cash/loan shrinking significantly.
Three mitigation strategies: facilitating lease financing for the long tail, driving down installation costs via 5th-gen batteries (50%+ energy density improvement) and IQ9 with GaN, and reducing customer acquisition costs through lead generation.
Channel inventory is described as “slightly above” the normal 8-10 weeks; mgmt expects 25D-related demand pull to rightsize channel inventory by year-end.
Mgmt stance: Cautious on 2026 TAM but bullish on internal mitigation plans, citing product innovation and partnerships as levers to offset market decline.
Q2 — Philip Shen
Topic: Q3 safe harbor revenue, 25D demand pull timing, channel inventory levels, and 2026 TAM assumptions.
Key points:
Q3 revenue guidance includes zero safe harbor revenue; TPO partners await further clarity on a recent Executive Order.
Mgmt expects 25D-related demand pull to begin in early Q4, not yet visible in Q3.
Channel inventory is “slightly above” the normal 8-10 weeks; mgmt states they will not return to the anomalous undershipment levels of the past two years.
2026 TAM assumption breakdown: U.S. solar TAM declining from 4.5 GW to 3.5 GW, with lease moving from 2 GW to 2.5 GW and cash/loan dropping from 2.5 GW to 1 GW.
Mgmt stance: Cautious on near-term visibility (no safe harbor in Q3 guide) but confident in Q4 demand materializing and maintaining tight channel control.
Q3 — Brian Lee
Topic: Cost and timeline for strategic initiatives (TPO financing, lead gen) and pricing strategy in a declining TAM.
Key points:
Mgmt does not anticipate any major increase in operating expenses to facilitate TPO financing or lead generation initiatives.
Pricing strategy relies on innovation-driven cost reduction: 5th-gen batteries with prismatic cells and IQ9 with bidirectional GaN switches are expected to fundamentally improve margins, creating room for value-based pricing.
New product introductions include a 3-phase 480-volt product for the first time.
Mgmt stance: Bullish on maintaining competitiveness through product innovation, stating that fundamentally altered cost structures will allow for appropriate pricing without margin sacrifice.
Q4 — Unknown Analyst (Dishant for Julien)
Topic: Dynamics of Q4 safe harboring and 25B demand pull-through.
Key points:
Mgmt clarifies that TPO partners have until approximately June 30 of the following year to finalize safe harbor inventory, distinguishing this from 25B rules.
For 25B (requiring both customer payment and installation by year-end), mgmt expects the demand rush to happen, citing installer expertise and their ability to quickly expand crews and complete installations.
Mgmt stance: Bullish on Q4 25B demand materializing, expressing confidence in installers’ ability to manage the year-end rush.
Q5 — Colin Rusch
Topic: Upsell opportunity to existing homeowners and growth outlook for non-U.S., non-EU markets.
Key points:
Mgmt sees a large opportunity in its 4.9 million home installed base, with significantly lower customer acquisition costs. AC-coupled architecture allows adding batteries or EV chargers without touching the existing solar system.
Australia: A new government battery rebate is expected to drive battery attach rates from 30% to 80-90%. New product introductions (flex phase battery, high-powered microinverters) are expected to resume growth starting Q3.
India: Steady quarter-over-quarter growth driven by IQ8 P system and battery for premium resilience applications; not a “hockey stick” but consistently higher.
Japan: Product introduced mid-Q2; ramp-up expected to take time but is a big opportunity, with Balcony Solar and batteries planned for next year.
Mgmt stance: Bullish on the upgrade market and international expansion, citing specific product roadmaps and favorable policy changes in Australia.
