The rol...

Installing sustainable and renewable energy systems is a promising way of relieving Hong Kong’s dependence on imported fossil fuels. Solar photovoltaic (PV) technology is a perfect solution for Hong Kong as it fits the economic and geographic situation. Through a review of the PV development history of five leading PV countries, Germany, Japan, Italy, Mainland China, and the USA, this paper ser...

After setting PhotoVoltaic (PV) plant up, it needs to monitor its energy performance in order to verify the correct or incorrect operation. For this aim, PV plants can be equipped with simple dataloggers or SCADA systems. When several PV plants have to be monitored, a unique supervision centre is implemented, even if each PV plant is independent from the others. From the point of view of storin...

The optimal hybridization of photovoltaic (PV) and thermoelectric (TE) devices has long been considered ideal for the efficient harnessing solar energy. Our hybrid approach uses full spectrum solar energy via lossless coupling between PV and TE devices while collecting waste energy from thermalization and transmission losses from PV devices. Achieving lossless coupling makes the power output fr...

The power interruption in factories, hospitals, and airports is a critical problem that should be avoided. The solution is uninterruptible power supply (ups) system. Such problem may be solved by introducing solar photovoltaic (PV) or diesel generators (DG)in the ups system. Knowing that the economic problem of providing electrical energy to factories, hospitals, workshops,....etc. may be solve...

Time interval and time length are two important indexes when analyzing the active output data of photovoltaic (PV) power stations. When the time interval is constant, the length of time is too small, and the included information is less, resulting in a lack and distortion of information; it the length of time is too large, the included information is redundant and complicated, resulting in unne...

There is a renewed interest in photovoltaic solar thermal (PVT) hybrid systems, which harvest solar energy for heat and electricity. Typically, a main focus of a PVT system is to cool the photovoltaic (PV) cells to improve the electrical performance, however, this causes the thermal component to under-perform compared to a solar thermal collector. The low temperature coefficients of amorphous s...

This paper presents a design for a stand-alone photovoltaic (PV) system to provide the required electricity for a single residential household in rural area in Jordan. The complete design steps for the suggested household loads are carried out. Site radiation data and the electrical load data of a typical household in the considered site are taken into account during the design steps. The relia...

Abstract: Available photovoltaic (PV) systems show a prolonged transient response, when integrated into the power grid via active filters. On one hand, the conventional low-pass filter, employed within the integrated PV system, works with a large delay, particularly in the presence of system’s low-order harmonics. On the other hand, the switching of the DC (direct current)–DC converters within ...

Purpose Renewable energy components such as Building Integrated Photovoltaic (BIPV) often influence the aesthetic quality of a building adversely and hence need to be analyzed for their impact on building form and aesthetics. This becomes crucial especially in the case of a sun-tracking photovoltaic system. Moreover, there is a need to propose a reasonably accurate but quick system to estimate ...
