Hoymiles Presents 2025 Sustainability Report

Hoymiles Power Electronics, a prominent player in the solar energy sector, has recently published its 2025 Sustainability Report. This detailed document outlines the company's initiatives and achievements in the realms of environmental responsibility, social contributions, and corporate governance. Hoymiles aims to demonstrate that by enhancing its Environmental, Social, and Governance (ESG) framework, it can further drive high-quality growth and sustainable development over the long term.

Commitment to Green Manufacturing

In terms of ecological responsibility, Hoymiles has prioritized green manufacturing. They are focusing on promoting clean production methods and utilizing low-carbon energy. During the reporting year, Hoymiles earned the title of a 2025 Hangzhou Municipal Green and Low-Carbon Factory Model Enterprise. This accolade underscores their success in adopting sustainable manufacturing practices.

One of the key strategies has been the installation of a rooftop photovoltaic (PV) system at their smart manufacturing facility. This solar installation allows the factory to operate on clean energy, which has led to a green power consumption rate of 22.81%. Additionally, the company successfully decreased its total greenhouse gas emissions to approximately 4,285.90 tCO₂e and achieved a 100% compliance rate in pollutant monitoring. Such advancements significantly bolster the company's efforts in managing its carbon footprint and transitioning to renewable energy.

Social Impact Through ESG Commitments

Hoymiles is not merely focused on environmental sustainability; it also integrates social responsibility into its business development strategies. Throughout 2025, the company collaborated with the German nonprofit Climate Connect to initiate the "2025 Solar Panel Upcycling World Record Challenge." This project, which unfolded across five cities in Germany, aimed to repurpose recycled PV modules into balcony solar systems, thus promoting circular economy practices.

Moreover, Hoymiles contributed substantially to a public housing solar initiative in the Netherlands by supplying more than 28,000 microinverters. This project benefited around 50,000 residents by alleviating energy poverty and has been projected to reduce CO₂ emissions by about 17,000 tons. Such projects exemplify how Hoymiles is transforming its ESG commitments into practical social impacts.

Strong Governance and Global Ratings

Sustainability principles are interwoven throughout Hoymiles' product lifecycle as well as its corporate governance framework. The company has received commendations for its robust ESG management practices, leading to an EcoVadis Gold rating. This recognition places Hoymiles among the top 4% of companies evaluated by the international sustainability ratings organization. Additionally, it achieved an AA ESG rating from Sino-Securities and an A rating from Wind, reflecting substantial confidence from both international evaluators and capital markets regarding Hoymiles' capability for sustainable development.

Expanding Globally While Empowering Locally

As a frontrunner in smart solar and energy storage solutions on a global scale, Hoymiles abides by core values of integrity, responsibility, professionalism, and efficiency. Collaborating closely with partners across the globe, the company aims to hasten the energy transition.

In 2025, Hoymiles introduced localized solar-plus-storage empowerment initiatives across various regions including Germany, the Netherlands, Vietnam, and Brazil. These community programs aim to deliver both environmental and social advantages. In Vietnam, Hoymiles played a critical role as the sole microinverter supplier for the national demonstration program, Balcony Solar System for Vietnam (BSS4VN), which supports the deployment of distributed solar applications and bolsters local renewable energy adoption.

As reported by SP Global, Hoymiles accounted for 22% of global microinverter shipments in 2024, securing the top position in international markets outside the United States. The company also remains a Tier 1 energy storage manufacturer as per BloombergNEF's ratings, with its intelligent solar and energy storage solutions now catering to clients in over 190 countries and regions.

The management at Hoymiles indicated in the report that 2025 serves as their 'Year of Transformation.' They are realigning their core strategy toward developing integrated solutions combining PV and energy storage while steadily increasing their R&D investment. Hoymiles is committed to advancing the global energy transition by continually delivering efficient and reliable solar and storage solutions. Through ongoing technological innovations and responsible business operations, the company aims to contribute to creating a cleaner, safer, and more efficient global energy system.
