  • This technology would lead to the saving of fossil fuels to a great extent as 1 unit of energy saved is equivalent to 3 units of energy generated.  solar lighting device Solar Jyoti launched by Dr.HarshVardhan
  • Incubation centres will be brought up under the Start up India, Stand up India programme which would encourage entrepreneurship in the solar sector to make commercialization of the device viable.

 SalientFeatures:

  • If this technology is adopted in 10 million households only, it has the potential of saving 1750 million units of energy.

How it Works:

  • The Micro Solar Dome absorbs sunlight by a transparent semi-spherical upper dome and concentrates it inside a dark room.
  • The Captured light passes through a sun-tube having a thin layer of highly reflective coating on the inner wall of the passage.
  • It is leak proof and works for almost 16 hours daily and throughout the day and 4 hours after sunset.
  • The Photo-Voltaic Integrated Micro Solar Dome costs about Rs.1200 and the Non Photo-Voltaic version around Rs. 500.
