the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...

Off-grid Photovoltaic (PV) systems are empowering technology in underdeveloped countries like Ethiopia where many people live far away from the modern world. Where there is relatively low energy consumption, providing energy from grid systems is not commercially cost-effective. As a result, significant people groups worldwide stay without access to electricity. One remote village in northern Et...

This paper proposes a new power management control method for microgrids based on H∞ control theory. Microgrid systems consist of distributed power sources such as cogeneration systems and photovoltaic systems with batteries. In general, power generation by photovoltaic systems and power consumption of various loads cause large fluctuations depending on weather conditions and varied lifestyles....

Performance, quality and reliability issues are becoming more and more important for the emerging photovoltaic markets worldwide. The purpose of this work is comparing and presenting operational performance results of grid-connected PV systems, as collected and elaborated for Task 2 of the Photovoltaic Power Systems Programme (PVPS) of the International Energy Agency (IEA). The data analysed he...

The last 20 years have presented a favorable scenario for the incorporation of renewable energy sources into the energy matrix of developing countries. This situation promoted grid connected photovoltaic generation systems (GCPVS) to become one of the main protagonists in this new concept of energy matrix. In some developing countries the use of such systems is in its beginning. Promotion polic...
