REGIONAL VARIATION IN SOLAR DSI ACROSS INDIA

  1. The Himalayan region has very high potential of developing solar energy. 

DEFECTS IN SOLAR PV MODULES

Defects come in Solar PV modules which lead to lower efficiency of conversion of solar energy to electricity. Some of the common defects in Solar PV modules are:

  1. Due diligence should be exercised while selecting and procuring modules. 
  2. Degradation of PV modules in hot climates as compared to cooler climates. This is particularly important for India, 
  3. Micro-cracks caused due to transport and installation phases.
  4. Solar power plants should be developed in the cold and sunny areas of Himalayas. This region has very low degradation rates of solar PV modules & high-performance ratios. This region is also endowed with highest irradiance in India and easy availability of large stretches of land. 

WAY FORWARD

  1. Developing solar power plants in regions with high Diffused Solar Irradiance. For ex. Ladakh, Northeast, Odisha etc. and other similar areas for expansion of solar power generation. Grids should be constructed for evacuation of power from this region. 
  2. Developing solar power plants in wasteland areas.
  1. Using better quality and higher efficiency silicon PV modules in solar power plants. For ex. Perovskite solar cells etc.
  2. Promoting non-power usages of solar energy such as solar water.
  3. Promotion of solar power plants over canals.
