  • About: It refers to a photovoltaic system where solar panels are installed on the rooftop of residential or commercial buildings.
  • Size: Rooftop mounted systems are relatively small when contrasted with ground-mounted photovoltaic power stations, which typically have capacities in the megawatt range.
  • Residential Rooftop PV Capacity: Rooftop PV systems on residential buildings typically possess a capacity ranging from 5 to 20 kilowatts (kW), showcasing their suitability for smaller-scale energy generation.
  • Commercial Rooftop PV Capacity: In contrast, commercial buildings often host rooftop PV systems with significantly larger capacities, frequently exceeding 100 kilowatts (kW), making them robust contributors to the energy grid.
  • Benefits :

oSavings up to 15-18 thousand rupees annually for households from free solar electricity and selling the surplus to the distribution companies;

oCharging of electric vehicles;

oEntrepreneurship opportunities for a large number of vendors for supply and installation;

oEmployment opportunities for the youth with technical skills in manufacturing, installation and maintenance.

  • Rooftop solar (RTS) Energy: India achieved 8.07 gigawatts of rooftop solar (RTS) installations by December 2022, out of the 40 GW of the target.

PM Suroyadaya Yojna: It aims to provide electricity to low and middle-income individuals through solar rooftop installations, along with offering additional income for surplus electricity generation.
