Overview
On October 29, the PV-storage equipment sector saw another round of concentrated price increases. Huawei Digital Power and Kehua Data’s subsidiary Kehua Digital Energy both announced adjustments the same day: Huawei raised residential and C&I PV-storage solutions and string inverters by 5%–15%, and grid-forming storage solutions by 5%–10%; Kehua will lift all product lines by 5%–15% from November 1. Both cited multiple rounds of increases in bulk commodities, PCB and memory prices, plus tighter supply of key electronic components.
This is the latest in a wave of second-half price hikes. Sungrow (from September 20, +5%–15%), Growatt (from October 8, +5%–10%) and Kstar had already issued notices covering inverters, PCS and storage systems.
Background & Interpretation
1. Industry and Policy Context
While downstream PV module prices kept falling and price-for-volume became the norm, equipment-side input costs moved the opposite way. Inverters are the brain of PV-storage systems; metals (copper, aluminum, silver, gold) and IGBT power devices dominate their cost and are highly sensitive to upstream swings. This round signals a turning point in the chain’s cost pass-through—manufacturing pressure is surfacing in equipment prices.
2. Core Drivers and Underlying Mechanisms
The cost push has three layers: persistent rises in copper, aluminum, tin and precious metals; tighter supply of power devices and PCBs; and the fact that prior absorption via long-term contracts and supply-chain optimization has run past its limit. Once costs cross a threshold, repricing becomes necessary to sustain delivery and quality.
3. Market Structure and Industry Chain Effects
Whether increases pass through remains to be tested. With PV installation growth slowing and some inverter tender volumes shrinking, downstream bargaining power is not weak. Leading brands with channels and system capability can pass costs on; smaller players face a dilemma between losing orders by hiking and losing margin by not.
Implications & Outlook
Near term, the price center for inverters and storage systems may drift up, aiding equipment-makers’ margin repair; but project IRR is sensitive to upfront cost, and squeezed returns could delay some installations. Longer term, firms with in-house core-device R&D and vertical integration will prove more resilient across price cycles.
Takeaways for Industry Participants
Equipment makers should strengthen long-term supply agreements and cost-transparency management rather than blindly follow hikes; downstream developers should re-evaluate whole-lifecycle cost and reliability in tenders, not award solely on lowest upfront price.
