EUPD Research Announces the Publication of the Brand Leadership & Sustainability Rating – Europe (BLSR)

Bonn, Germany, June 2025 – EUPD Research announces the publication of the Brand Leadership & Sustainability Rating – Europe (BLSR©️), a comprehensive assessment of leading brands in the fields of Photovoltaics (PV), Electrical Energy Storage (EES), and Inverters active in the European market. The report is now available and provides a valuable reference point for manufacturers, investors, installers, intermediaries, and end customers – enhancing transparency and supporting long-term viability in the renewable energy sector.

As Europe’s Commercial & Industrial (C&I) solar segment becomes increasingly complex, market participants face growing challenges in assessing supplier landscapes and navigating regulatory uncertainty. The BLSR©️ delivers structured, data-driven insights that complement conventional evaluation criteria and enable more resilient and forward-looking decision-making – particularly in the C&I segment.

What distinguishes the BLSR©️ is its multi-dimensional methodology, integrating EUPD Research’s primary research with secondary data analysis, stakeholder input, and a balanced combination of quantitative and qualitative metrics. This approach reflects EUPD Research’s commitment to robust, evidence-based market evaluations – especially valuable in periods of heightened volatility and evolving stakeholder expectations.

The assessment framework includes four key dimensions:

  1. Market Feedback & Primary Data – Insights from installers, EPCs, C&I stakeholders, and prosumers, covering brand awareness, market penetration, satisfaction, and Net Promoter Score across Europe.
  2. ESG Reports & Innovation – Evaluation of sustainability efforts, transparency, and investment in research and development.
  3. Price-Performance Ratio – Assessment of product quality in relation to cost, based on a representative sample of 3–6 products per brand.
  4. Financial Health Check – Analysis of current and short- to mid-term financial stability, based on publicly available financial data (for listed companies).

Only manufacturers that demonstrate clear market relevance through primary research and meet transparency standards via financial disclosure are included in the rating. Despite ongoing market challenges, several brands have achieved top-tier status:

  • Photovoltaic Modules: Jinko Solar, JA Solar, Canadian Solar, LONGi Solar
  • Inverters: SolaX Power, Sungrow, SMA, GoodWe
  • Storage Solutions: BYD, Pylontech, Tesla

The complete report, including methodology and an overview of all assessed manufacturers, is available upon request.
