This paper presents the life cycle cost analysis of the single slope passive and hybrid photovoltaic (PV/T) active solar stills, based on the annual performance at 0.05 m water depth. Effects of various parameters, namely interest rate, life of the system and the maintenance cost have been taken into account. The comparative cost of distilled water produced from passive solar still (Rs. 0.70/kg...

Solar energy conversion into electricity by photovoltaic modules is now a mature technology. We discuss the need for materials and device developments using conventional silicon and other materials, pointing to the need to use scalable materials and to reduce the energy payback time. Storage of solar energy can be achieved using the energy of light to produce a fuel. We discuss how this can be ...

This work presents a mathematical model for the payback time of reusing electric vehicle batteries as residential energy storage systems from end life automotive application. The was developed using MATLAB software and calculates battery system (BESS) under different scenarios while considering daily electricity consumption profile UK household. results show that purchase price, BESS capacity, ...
