A step forward in précising building roof top areas for Solar PV installations

Solar Photo Voltaic (SPV) systems are expected to become one of the most ideal renewable energy resources in India which can be implemented in large scale across different states. This paper presents in-depth investigation of various tools available for the assessment of building rooftops. The gaps in these tools have analyzed in detail. The pressing need of developing a new user friendly tool has been substantiated in this paper. The features and parameters which should be included in the new software/tool have been deliberated in detail. Various formulae and the procedure which need to be programmed in the development of new software have also been discussed in detail. The findings presented in this paper are expected to provide a pathway forward for precise building rooftop area calculations leading to efficient space utilization and subsequent environment benefits.
