Most parts of India have good solar insolation (more than 1900 kWh/m2/year) with about 300 days of sunshine. The Indian government launched the Jawaharlal Nehru Solar Mission in 2010 with plans to establish 20 GW of grid connected solar power by 2022. We review the status of progress in Solar Photovoltaics and Solar Thermal for grid connected power in India. The existing capabilities for technology development and research in solar power in India are reviewed.
IIT Bombay has been involved in setting up a MW scale National Solar thermal power demonstration facility. A consortium of industries is involved in this project which plans to enable the development of future cost effective solar thermal power plants. We describe the experience involved in setting up the consortium and the facility and evolution of the plant design. The plant is a combination of parabolic trough collectors to heat a heat transfer oil and a linear Fresnel reflector field to generate steam. The two solar fields have being integrated using a heat exchanger. The plant has buffer oil storage. This talk will describe some of the design trade-offs involved and the decisions taken related to operations and control strategy. A simulator has been built to analyse the performance of alternative solar thermal power plant configurations.
We outline the challenges for technology development and research for concentrated solar power in India.
