• Bengaluru recently conducted a series of aerial surveys to gauge the potential of rooftops for solar energy generation.
  • The surveys were conducted using the light detection and ranging (LiDAR) technology, which has high accuracy and works quicker for data collection as compared with other tools of aerial mapping.
  • Rooftop solar energy is expected to contribute 40 GW to India’s goal of 100 GW solar power by 2021-22.

A recent series of aerial surveys of Bengaluru, using the Light Detection and Ranging (LiDAR) technology, could possibly be a pioneer project to assess the potential for rooftop solar photovoltaic energy in urban centres in India. Using the LiDAR technology, which is otherwise used to assess biomass in forests, experts could quickly gauge the real potential for implementing solar energy in Bengaluru.

The aerial survey in Karnataka’s capital city intends to identify the most suitable rooftops and eventually achieve the capacity to generate a targeted 1 GW of solar energy in Bengaluru alone by 2021-22.
