Hoymiles has released its 2025 Sustainability Report, detailing its transition toward low-carbon manufacturing. The company has integrated rooftop solar PV systems into its production bases to lower its reliance on fossil fuels. Key achievements include a green power consumption rate of 22.81% and a reduction of total greenhouse gas emissions to 4,285.90 tCO2e. These steps are part of a broader ESG framework aimed at decarbonizing the production of renewable energy hardware.

A 22.81% green power rate is a start, but it means nearly 80% of their manufacturing still relies on the local grid. Given they are based in Hangzhou, that is a lot of coal. I wonder what the actual timeline is to hit 100%.
The reporting is standard ESG fluff, but the 4,285 tCO2e figure is a concrete metric we can actually track. The real question is whether these reductions are from actual efficiency gains or just shifting loads to different regions.
Basically a corporate update on their solar roof and emissions numbers. It is good to see hardware makers cleaning up their own supply chains, even if the report is heavy on the ESG buzzwords.
