PERC Module Prices up 20% in the US, as Overall Module Prices Remain Constant

Why It Matters

The price swing highlights how U.S. policy incentives can reshape technology adoption and cost structures across the solar supply chain, affecting project financing and domestic manufacturing growth.

Key Takeaways

• Mono PERC price rose 20% to $0.33/W.
• TOPCon fell to $0.28/W, now cheaper than PERC.
• US‑made solar cells jumped 8.2% to $0.49/W.
• Imported cell prices rose 4.9% to $0.325/W.
• BESS prices stable; utility‑scale at $178/kWh.

Pulse Analysis

The recent 20% surge in mono PERC module pricing underscores the power of policy‑driven demand spikes. As the July 3 investment tax credit safe‑harbor deadline approached, developers rushed to secure U.S.-made panels that qualify for the domestic‑content bonus, inflating prices for both PERC modules and American‑produced cells. This behavior mirrors the earlier December 2025 deadline rush, illustrating how tax credit timing can create short‑term price volatility even when the broader module market remains flat.

Technology mix dynamics are also shifting. TOPCon modules, once competitive with PERC, slipped to $0.28/W, partly because ongoing patent disputes have discouraged developers from committing to that platform. Meanwhile, heterojunction (HJT) continues to sit at the top of the price ladder, reinforcing PERC’s role as the cost‑effective, mature alternative. The divergence forces project planners to balance efficiency gains against higher upfront costs, especially when domestic‑content rules limit the pool of eligible components.

In the storage arena, price stability offers a counterpoint to solar‑module turbulence. Distributed‑generation battery packs saw a modest 3.4% price dip, while utility‑scale 200 MW systems settled around $178/kWh after an 8.6% decline since late 2025. Coupled with Anza’s forecast of domestic solar‑cell manufacturers rising from 12 to 15 and BESS suppliers more than doubling by mid‑2027, the data suggest a maturing U.S. clean‑energy ecosystem where supply‑side capacity expansion may soon temper cost pressures. Developers that align with domestic‑content incentives are likely to benefit from both tax credits and a more resilient supply chain.
