This paper presents exergoeconomic, enviroeconomic and productivity analyses of basin type solar stills by incorporating N identical photovoltaic thermal (PVT) compound parabolic concentrator (CPC) collectors commonly known as PVT-CPC active solar distillation systems. In this work, the mass flow rate and the number of collectors have been optimized and values of yearly distillate output, energy, exergy and cogeneration efficiency have been computed for the proposed solar distillation systems at 0.14 m water depth for the same basin area under composite climatic conditions of New Delhi. The exergoeconomic parameter, enviroeconomic parameter, productivity and cogeneration efficiency for double slope PVT CPC active solar distillation system have been found to be higher by 16.22%, 21.48%, 8.56% and 5.73% respectively than obtained from a similar single slope set up at a water depth of 0.14 m for the same basin area under similar climatic condition. The proposed system can meet the potable water needs on a commercial scale and generate DC electrical power during sunshine hours. (C) 2016 Elsevier Ltd. All rights reserved.
