Solar photovoltaics have a finite service life, after which they are decommissioned. The volume of obsolete or end-of-life solar PVs is expected to be mammoth in future, owing to their extraordinary deployment in the past decade. The domination of a linear solar PV paradigm alongside a parabolic increase in solar PV installations makes the exacting challenges of the end-of-life management of solar PVs seem inevitable. Therefore, this research intends to draw policymakers' attention toward sustainable end-of-life options. The main contribution of this research is the provision of an integrated decision-making model which ascertains the extent of sustainability of four end-of-life solar PV management scenarios from the lens of a triple bottom line approach. The model includes a forecasting framework for two different installation periods and various waste projection scenarios. Following, it utilizes holistic methodologies such as the life cycle assessment, cost-benefit approach and social indicators for determining the environmental, economic and social sustainability impacts of the end-of-life solar PV scenarios. The devised framework is implemented as a case study (on Spain) to further increase the research's granularity. Utilizing the expert responses garnered through questionnaires, criteria weights for the three sustainability dimensions and assessment indicators are calculated and an overall sustainability score for each end-of-life scenario is derived. This research also inclusively emphasizes the drivers, enablers and barriers of sustainable end-of-life PV management to cope with the momentous volume of end-of-life solar PV in future.

The performance and ranking pattern of PV systems incorporated with solar trackers in the northern hemisphere Bahrami, Arian; Okoye, Chiemeka Onyeka (2018-12-01) Energy produced from a typical PV panel with or without solar tracker is mainly dependent on the available solar irradiance. Interestingly, for some locations on nearly the same latitude in the northern hemisphere, the solar irradiance varies significantly resulting to change in the ranking pattern of solar PV trackers. For this reason, the present study aims to explore the effect of solar irradiation on the technical and economic performance of PV panels incorporated with different solar trackers. Particul...
Study Case of Solar Thermal and Photovoltaic Heat Pump System for Different Cities in Turkey Moia-Pol, Andreu; Pujol-Nadal, Ramon; Martinez-Moll, Victor; Bonyadi, Nima; Baker, Derek (2016-10-14) The combination of solar thermal, photovoltaic, and heat pump technologies is a welcome advancement in countries with large solar resources such as Turkey. These systems could have similar efficiencies throughout the year for different locations in Turkey if we adjust the solar storage according to the weather conditions. In this paper, solar heating with a heat pump system for buildings have been designed to achieve different values of the fraction of primary energy saved using Flat Plate Collectors (FPC) ...
A new economic feasibility approach for solar chimney power plant design Okoye, Chiemeka Onyeka; Solyali, Oguz; Taylan, Onur (2016-10-15) Solar chimney power plants have been accepted as one of the promising technologies for solar energy utilization. The objective of this study is to propose an effective approach to simultaneously determine the optimal dimensions of the solar chimney power plant and the economic feasibility of the proposed plant. For this purpose, a two-stage economic feasibility approach is proposed based on a new nonlinear programming model. In the first stage, the proposed optimization model which determines the optimal pl...
Optimizing the orientation of solar photovoltaic systems considering the effects of irradiation and cell temperature models with dust accumulation Al-Ghussain, Loiy; Taylan, Onur; Abujubbeh, Mohammad; Hassan, Muhammed A. (2023-01-01) To cope with the growing installation capacities of solar photovoltaic (PV) systems in desert areas, it is necessary to revisit the energy production models and the optimal angles of PV panels given the significant impacts of ambient temperature, wind speed, dust accumulation, and cleaning frequency. In this study, these four factors are examined for four PV technologies (polycrystalline, microcrystalline, monocrystalline, and thin-film) at three cities in Jordan, Egypt, and Tunisia using precise ground-lev...
Design and realization of a new concentrating photovoltaic solar energy module based on lossless horizontally staggered light guide Selimoğlu, Özgür; Turan, Raşit; Department of Physics (2013) Concentrating Photovoltaic systems are good candidates for low cost and clean electricity generation from solar energy. CPV means replacing much of the expensive semiconductor photovoltaic cells with the cheaper optics. Although the idea is simple, CPV systems have several problems inherent to their system design, such as module thickness, expensive PV cells and overheating. Light guide systems are good alternatives to classical CPV systems that can clear off most of the problems of those systems. In this t...
