The renewable energy transition in India is at a critical juncture. Intent on reaching an ambitious goal of 500 GW of renewable capacity by 2030, rooftop solar and off-grid solar deployment has begun to ramp up across residential, commercial, and industrial sectors. The intermittency of solar as a source of energy has driven the need for energy storage solutions.
Solar users, whether a rural household with an off-grid system or an urban industry with rooftop solar systems, must use reliable storage systems in order to have dependable access to renewable energy 24/7, back up and grid stability, and to lower energy costs. The Indian industry is looking to address this need with new battery technologies, battery + hybrid storage systems and integrated energy management systems.
