## REDUCTION IN SIZE OF PHOTOVOLTAIC PANELS

## 1308. SHRI PONGULETI SRINIVASA REDDY:

Will the Minister of NEW & RENEWABLE ENERGY be pleased to state:

- (a) whether the Union Government is planning to introduce sophisticated technology to reduce the size of photovoltaic panels, which generates same amount of power and occupies less space in a bid to overcome the challenge of scarcity of land for further expansion of solar power Industry;
- (b) if so, the details thereof;
- (c) whether the Union Government has taken any steps for technological upgradation of solar panels/appliances to be synchronized with solar irradiance: and
- (d) if so, the details thereof?

## ANSWER

## THE MINISTER OF STATE (IC) FOR POWER, COAL, NEW & RENEWABLE ENERGY AND MINES (SHRI PIYUSH GOYAL)

- (a): Ministry of New & Renewable Energy (MNRE) is supporting an R&D schemes under which  the  efforts  are  being  made  to  make  the  more  efficient  Solar  cells/Solar  module  to generate  more  power  with  same  area.  MNRE  has  sanctioned  several  R&D  projects  for development of high efficiency solar cells which will require less area for deployment of the PV modules.
- (b): The details of R&D projects are given in the Annexure.
- (c) & (d): The grid tied inverters being used in the PV power plants to fed the power to the grid are of high quality with total harmonic distortion (THD)  < 3 % and overall system efficiency including Maximum Power Point Tracking ( MPPT) >96%. There is no problem of synchronization due to solar irradiance.
