TL;DR — three sentences

  • Tier-1 solar module utilization fell from 75% in 2023 to around 60% in 2026 as capacity exceeded demand. (S1)
  • BESS differentiation is shifting toward software, cybersecurity, energy management and integrated offerings. (S1)
  • CATL is investing in data-center power infrastructure as AI demand creates a BESS growth opportunity. (S1)

Reported by PV Magazine on November 7, 2026. Summarized and analyzed by XAIPART Editorial.

What happened

Solar and battery energy storage systems manufacturers face converging strategic pressures as their markets expand, with hardware becoming a weaker source of differentiation and margins under pressure. Solar is already in an oversupply cycle, while BESS remains in a growth phase but is beginning to experience price competition as manufacturing capacity expands, particularly in China.S1

Global module manufacturing capacity exceeded 1.1 TW in 2025, nearly twice annual demand, and average utilization by Tier-1 PV module manufacturers fell from 75% in 2023 to around 60% in 2026. Lower factory loading raised unit costs while price competition and slower Chinese demand pressured margins.S1

Manufacturers are responding through geographic diversification, integrated offerings and additional sources of demand. In BESS, value is moving beyond cells and system design toward software, cybersecurity, energy management and complete solutions; cell manufacturers are also moving downstream, while integrators face capital and technical barriers to entering cell production.S1

CATL, BYD, LG Energy Solution and Gotion are identified as scaled manufacturers better positioned to commercialize new battery chemistries. Fluence Energy has secured master supply agreements with two major hyperscalers, and CATL is investing in data-center power infrastructure.S1

Background timeline

  1. - Installed solar capacity was 220 GW and BESS capacity was 2.2 GW.S1
  2. - Average Tier-1 PV module utilization was 75%.S1
  3. - Average Tier-1 solar revenue later exceeded three times its 2018 level by 2023.S1
  4. - Tier-1 companies represented 83% of global solar module shipments and 62% of BESS shipments.S1
  5. - Installed solar reached 2.7 TW and BESS reached around 470 GW.S1
  6. - Cumulative capacity is projected to exceed 8 TW for solar and 2.4 TW for BESS.S1

XAIPART take

Technical impact

XAIPART analysis Engineers should evaluate BESS suppliers on control software, cybersecurity, energy-management functionality and commissioning quality rather than treating battery hardware as the sole selection criterion. Integration scope also affects replaceability, because a supplier offering a complete system may create more switching and configuration risk than a component-focused vendor.

Market impact

XAIPART analysis Buyers should expect more commercial leverage in solar modules because excess factory capacity can support aggressive pricing. No lead-time figures were disclosed, so procurement teams should request current quotations and factory-loading data rather than assuming that lower utilization guarantees shorter lead times for every component.

Action

XAIPART analysis Split sourcing reviews into two tracks: module purchasing focused on total cost, quality and available production capacity, and BESS purchasing focused on software interoperability, warranty scope and service capability. For new programs, request evidence that suppliers can support chemistry changes, grid-code requirements and data-center deployment schedules.

XAIPART Forecast

XAIPART analysis XAIPART expects average Tier-1 PV module utilization to remain at or below 60% through Q1 2027, keeping commercial pressure on JA Solar and comparable suppliers. If published Tier-1 utilization rises above 60% during that period because of production discipline or stronger demand, this forecast is wrong.
