Based in Tamil Nadu, India, the world’s largest solar power plant with a capacity of 648 megawatt has become functional. Covering an area of 10 square kilometres, the $679 million project was completed within a record eight months. The solar plant is recharged by its own panels and is capable of providing electricity to nearly 150,000 homes. The plant is cleaned every day by a built-in robotic system. As part of the Government's Vision 2030, India has set a target of producing 40 per cent of its power from non-fossil fuels and by 2022 it aims to power 60 million homes with solar energy.
