Abstract
AbstractModern times have involved surplus use of solar photovoltaic technology in energy sector. India is incredible in its energy source category be it renewable or non-renewable sources. Average solar insolation of India is 5000 T kWh per year (i.e. ~600 TW), and major insolation accounts for states like Gujarat, Telangana and Rajasthan, etc. Western side between North latitude (23° 30′ and 30° 11′) and East latitude (69° 29′ and 78° 17′) locates Rajasthan. Annually it receives 6–7 kWh/m2 solar irradiance each day. 5109.96 MW of the total solar installation has been already done in Rajasthan, and further wider opportunity is available. End life recycling monetary aspects along with material recovery are also put forward. The current article focusses towards origin (2017) and retirement (2042) evaluation of 160 kW on grid rooftop solar PV plant installed in Bhartiya Skill Development University Jaipur Rajasthan. Objective of the paper is to lay down the complete cost analysis from set-up of the plant to its dismantling at the end life. Energy generated in the payback period also plays a key factor in deciding overall benefit from the installed plant. Such analysis will help in promoting the installation of rooftop solar panels at domestic and commercial level across the state. End life responsibilities should be taken care by the manufacturers to facilitate the steps for easy and economic recycling and also to eradicate the toxic components. This will be promoting the onset of independent and sustainable society in the crisis era of fossil fuels.KeywordsPhotovoltaicCost analysisGrid-connected payback
