  • Thermodynamic and life cycle assessment of flat–plate collector, photovoltaic system and photovoltaic thermal collector

    In this study, an energy, exergy and Life Cycle Assessment (LCA) analysis of a Flat–Plate (FP) collector, a Photovoltaic (PV) system and a Photovoltaic–Thermal (PV–T) collector is carried out for better evaluation. It is observed that instantaneous energy, daily energy and exergy efficiency of the FP collector, the PV system and the PV/T collector vary between 53–61%, 19–30%, 23–37% and 56–74%, ...

  • Energy and exergy metrics analyses of Hybrid Photovoltaic-Thermal air collector

    This paper presents the Energy Pay Back Time (EPBT) of Hybrid Photovoltaic-Thermal (HPVT) air collector based on exergy analysis for composite climate of New Delhi. The exergy metrics namely Electricity Production Factor and Life Cycle Conversion Efficiency in addition to EPBT have also been evaluated by using exergetic output. It has been observed that EPBT of HPVT air collector without balance ...

  • Photovoltaics Energy Technologies

    Technology Overview    Photovoltaic (or PV) cells are devices that use semiconductor materials—similar to those used in computer chips—to convert sunlight directly into electricity. The electric current can either be used immediately, or it may be stored, as in a battery, for later use. A typical PV or solar cell might be a square that measures about 4 ...

  • Photovoltaic Applications and Policy Initiatives

    Issue: The world photovoltaic (PV) market has grown significantly in recent years. Although this trend is expected to continue in the future, estimates cannot be given with any real certainty. Relevance: In this context the question that arises is the role that public and private funding plays in market development and how this funding should be used to ensure the best results. Although current ...

  • Thermal management of non–concentrating photovoltaic panels under extreme ambient conditions

    Solar photovoltaic modules have reduced efficiency levels when the ambient temperature is very high. In this paper, the temperature and the efficiency of a non–concentrating flat plate collector is determined by a one dimensional steady state analysis at different solar radiation levels for the city of Riyadh, Saudi Arabia where the radiation intensity and ambient temperatures are very high. The ...

  • Sustainable development of the Prefecture of Kephalonia

    An optimisation methodology is applied on the islands of Kephalonia and Ithaca (Prefecture of Kephalonia) in Greece, where various Renewable Energy Sources (RES) can be found and could be exploited to satisfy part of their energy needs. These resources are examined and a case study is performed for Kephalonia that involves an application of specific mathematical tools that will lead to a set of ...

  • Alternative scenarios of the utilisation of renewable energy sources in small prefectures: a case study in Lasithi Prefecture, Greece

    The sector of Renewable Energy Sources (RESs) is growing very fast, with many innovations and applications becoming a reality. The continuous reduction of natural resources has forced all policymakers to turn to alternative energy sources. The total energy (oil and electricity consumption) consumed in the prefecture of Lasithi during the years 1997?2002 in correlation with the RES exploitation ...

  • Harnessing the Sun`s Energy for Water and Space Heating

    The pace of solar energy development is accelerating as the installation of rooftop solar water heaters takes off. Unlike solar photovoltaic (PV) panels that convert solar radiation into electricity, these "solar thermal collectors" use the sun's energy to heat water, space, or both. China had an estimated 168 million square meters (1.8 billion square feet) of rooftop solar thermal collectors ...
