Hybrid solar container system launched for off-grid markets

The hybrid solar PV system—developed by STEAG Energy Services, a wholly owned subsidiary of STEAG Energy Services GmbH, Germany—can be quickly set up and put into operation on remote sites that have no grid or very poor grid availability.

Built on a 20-feet standard marine container, it can work as a grid-tied system where power is available and as an off-grid system where the grid is unavailable. The panels are fitted atop the container, providing it shade and helping control the temperature inside.

Around 8.5 square metres of free area is available inside the container, which can be used to set up facilities (like doctor’s clinic or cold storage) that would help the community.

The container initially serves as a transport container with which the entire equipment is delivered. At the destination, it will be placed on prepared platform/blocks, earthed and equipped with PV solar modules. The system can be connected to the grid as a portable plug-and-play solution.

The integrated renewable energy system is designed to lessen the energy burden in low-income areas. It will provide stable power that will fulfil basic needs and improve living conditions of people in rural and far-flung areas in India and other developing nations.

The system has been put on display near the TERI building at India Habitat Centre in New Delhi during the ongoing World Sustainable Development Summit. It will be marketed by STEAG in association with TERI.

Speaking on the occasion, Prof. Andreas Pinkwart, Minister for Economic Affairs, Innovation, Digitalization and Energy of the German Federal State of North Rhine-Westphalia, said, “The PV container solution, as developed by STEAG, is a proven template of innovative products being derived from joint know-how and competence, both from North Rhine-Westphalia and India. It would be my desire that further entrepreneurs from North Rhine-Westphalia would take the chance that the Indian market is offering them.”

Dr Ajay Mathur, Director General, TERI, said, “The solar-based plug and play option provides for services such as primary healthcare centres and cold storage spaces that are needed locally in remote locations.”

Joachim Rumstadt, CEO, STEAG GmbH said, “The system is a perfect example of German engineering experience realised in India for countries needing these solutions, including India and African countries. STEAG has been present in India for 18 years and has been offering high-end engineering technology expertise for engineering consultancy assignments and for carrying out comprehensive operation and maintenance of a variety of power plants and also providing innovative software solutions.”
