Pressurized water cleaning can improve PV generation efficiency by 10%
Researchers in China have investigated the dust-scaling process and various water-based cleaning methods to optimize maintenance strategies for enhanced safety and efficiency in PV systems.
Meeting sustainability goals: How overlooking EPR responsibilities can lead to costly consequences
Many countries require companies to show that they comply with environmental standards before accepting imports. The EU’s Packaging and Packaging Waste Directive sets the strictest recycling and waste disposal requirements, making non-compliance an obstacle to entry into the market. Companies that don’t adhere to these standards could struggle to grow internationally.
NTPC secures PPA with Indian Army for solar-hydrogen based microgrid project
