Limited domestic availability of floats is a big challenge and the industry has to depend on European or Chinese suppliers

Integration of large-scale variable renewable energy (VRE) generation resources -- wind and solar -- into national grids has been gaining importance as costs of these technologies, especially that of solar, continues to fall rapidly.

The ambitious project of Guru Nanak Dev University to have a solar energy plant on its campus is nearing completion.

A simple, low-cost solar water purifier (SWP) for rural households, which does not require electricity or waste precious water has been developed. The SWP consists of four tubular solar water heaters attached to a manifold. Non-potable water is filled in the SWP after filtering with four-layered cotton cloth and heated in the stagnation mode by solar energy to make it potable. The cost of the SWP is around Rs 2500–3000 (~US$ 40–50) and is so simple that any small rural workshop can fabricate it. In large-scale production it is envisaged that the cost can come down to Rs 1500. 

India has consistently been climbing up its Global Innovation Index (GII) rankings since 2015, but the country still has to improve on many indicators to catch up with China and others in the list of 126 nations.

Solar energy has ticked off all the necessary boxes to become a favourite of the suppliers in search of an efficient source of power.

In 1995, India became a member of the World Trade Organization (WTO) incurring obligations to provide market access to goods from other countries.
