The output power produced by high-concentration solar thermal and photovoltaic systems is directly related to the amount of solar energy acquired by the System, and it is therefore necessary to track the sun’s position with a high degree of accuracy. This paper presents sun tracking generating power system designed and implemented in real time. A tracking mechanism composed of photovoltaic modu...

In this letter, the authors numerically studied the optical properties of silicon photonic quasicrystal (PQC) nanohole array for photovoltaic applications. With the same active layer thickness, the ultimate efficiency of a solar cell integrated with an optimized PQC nanohole array can be enhanced by 9.01% and 1.40% as compared to that with an ordered square lattice of nanohole array and a rando...

Regenerative Fuel Cell (RFC) systems are used for the enhancement of sustainable energy aspect in conventional fuel cells. In this study, a photovoltaic-electrolyzer-fuel cell integrated cycle has been presented. The proposed system has been designed as a novel approach for alleviating the restrictions  on energy streams in the RFC systems. Modeling of the system has been performed from the mas...

ABSTRACT: In the power generation sector, Natural Resources like Solar, Wind, Tidal, Geothermal, Hydro etc have always played a very important role. Out of these solar PV (photo voltaic) is most popular due to its significant advantages. However the solar radiation never remains constant. It keeps on varying throughout the day. In this paper, single 60 W solar PV panel along with boost converte...

in this paper, the performance evaluation of a two-way hybrid photovoltaic/thermal (pv/t) solar collector was analytically and experimentally carried out. mathematical expressions for operating parameters in glass to glass and glass to tedlar pv/t solar collectors were developed and experimentally validated by a glass to tedlar pv/t solar collector system. also the influence of air flow rate on...

The conventional wisdom about solar array arcing in LEO is that only the parts of the solar array that are swept over by the arc-generated plasma front are discharged in the initial arc. This limits the amount of energy that can be discharged. Recent work done at the NASA Glenn Research Center has shown that this idea is mistaken. In fact, the capacitance of the entire solar array may be discha...
