In this paper, analytical expression for characteristic equation of double slope solar still (DS) included with series connected N identical evacuated tubular collectors (N-ETC-DS) has been developed. The derivation is based on fundamental energy balance equations for various components of the proposed system. The analytical result of the proposed N-ETC-DS has been compared with results reported by earlier researchers for the same basin area under similar climatic condition. It has been concluded that daily energy efficiency is higher by 23.90%, 26.45%, and 42.65% for N-ETC-DS than N identical partially covered photovoltaic thermal (PVT) compound parabolic concentrator collectors (CPC) integrated double slope solar still, N identical partially covered PVT flat plate collectors (FPC) integrated double slope solar still, and conventional double slope solar still (CDS), respectively, at 0.14 m water depth under optimized condition. Moreover, daily yield, exergy, energy and exergy efficiency have been computed.
