  1. 1. Digital mapping of techno-economic performance of a liquid-based solar photovoltaic/thermal (PVT) system over large geographical cities around the world

    University essay from Högskolan Dalarna/Energiteknik

    Author : Santhan Reddy Penaka; [2020]
    Keywords : PVT; Liquid-based; Techno-economic analysis; Digital mapping; Large geographical cities;

    Abstract : Photovoltaic thermal (PVT) collectors are widely used to harness a large fraction of the solar spectrum to generate electricity and heat from a single collector. The circulation of the working medium will pass through the collector which cools down the PV cell temperature and also increases the water temperature, which will increase the electrical and thermal performance at the same time.
