S&P Global names 2025 Tier 1 Cleantech Companies

S&P Global Commodity Insights uses a clear method. It looks at six areas: market presence, market share, scale, global reach, financial performance, and sustainability through the Corporate Sustainability Assessment (CSA). To make the list, a company must pass the threshold in at least four of these six areas. It’s a roster, not a rank from first to last, and names are listed alphabetically. The list does not give investment advice. 

S&P says this approach is transparent, annual, and based on real market data. It aims to cut noise from frequent reshuffles and hidden scores. Sustainability is built in, which fits rising rules on traceability and ESG. 

The CSA measures how firms manage sustainability risks and opportunities in their industry. It draws on disclosures, stakeholder input, media checks, and direct engagement. 

Why this list matters now

Clean energy factories grew fast in 2023 and 2024. Capacity rose faster than demand. Prices fell and margins got tight. Trade rules also got stricter for some regions. So, buyers want partners that can deliver at scale and stay strong when markets swing. 

S&P notes that Tier 1 solar manufacturers had average EBITDA margins 12 percentage points above the sector average. That’s a useful signal in tough cycles. 

Who’s on the 2025 list

The inaugural list covers four product groups. Each group includes firms that meet the method’s threshold. Here’s a simple view with examples; names in each group are in alphabetical order in S&P’s materials. 

CategoryCompanies recognizedExamples (not complete)
PV Modules14Trina Solar, Jinko Solar, LONGi, JA Solar, Tongwei, Canadian Solar, First Solar, Hanwha Solutions (Qcells), Astronergy, Risen, Seraphim, TCL Zhonghuan, GCL SI; DMEGC. 
PV Inverters12Huawei, Sungrow, GoodWe, Ginlong (Solis), Growatt, Deye, Sineng, Enphase, SolarEdge, SMA, TBEA, and Zhuzhou CRRC Times Electric. 
Wind Turbines9Vestas, Siemens Gamesa, GE Vernova, Goldwind, Envision, Ming Yang, Nordex, Sany Renewable Energy, and Windey. 
BESS (Energy Storage)12CATL, BYD, LG Energy Solution, Tesla Energy, Fluence, Wärtsilä, Sungrow, Canadian Solar, Envision, EVE Energy, Gotion High-tech, and Jiangsu Trina Solar Storage. 

Several names show up in more than one group. That reflects vertical scale from cells to systems. For example, Trina and Canadian Solar appear in both module and storage lists. 

How the method works

  • Scope: Four component groups: PV modules, PV inverters, wind turbines, and BESS. 
  • Six checks: presence, share, scale, global reach, finances, and CSA sustainability. Firms must exceed the threshold in at least four. 
  • Cadence: Updated yearly to give a stable reference for planning and procurement. 
  • Transparency: The list is public and alphabetized; it’s not a ranking, and it’s not advice. 
  • Data sources: Commodity Insights’ market database plus CSA sustainability data. 

Industry context

The supply chain for clean tech is crowded. Many new factories opened, and prices dropped. At the same time, rules on trade and supply checks got tighter. Buyers, lenders, and developers want partners that can ship on time and hold margins. This list is meant to reduce guesswork in that hunt. 

The 2025 list also shows a clear global mix. Chinese firms lead on volume in modules and inverters. Europe and the United States remain strong in wind. Storage shows wider spread, with cell giants and system integrators from Asia, Europe, and the U.S. all present. 

What the label does and doesn’t do

  • Does: help developers and lenders create shortlists fast. 
  • Does: recognize companies that meet a tough bar in scale, strength, and sustainability. 
  • Doesn’t rank winners and losers or tell you what to buy. 
  • Doesn’t replace due diligence on specific projects, sites, and service terms. 

Bottom line

This new Tier 1 list arrives when the market needs clarity. Prices are moving. Supply is high. Stakeholders want bankable kit and trusted partners. A public, method-based signal helps. It guides choices without hype, and it rewards firms that invest in quality and sustainability. 

For buyers, the message is simple: use the list as a starting point, not the finish line. Check warranties, local support, delivery times, and project track record. Then choose the fit for your site and your grid. That way, projects are more likely to stay on time, on budget, and online.
