In this work infrared thermography is used for the performance assessment of a photovoltaic array integrated on the southern façade of NTUA's Chemical Engineering Building. This grid-connected 50 kWp solar photovoltaic array, installed under an EC Thermie Project (SE-142-97-GR-ES), operates in a standard and hybrid PV-Thermal configuration, meant to save conventional energy. The thermographic s...

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...

To date, virtually all photovoltaic (PV) systems employ series-connected PV cells to some degree. A typical 4kW residential solar array, for example, might comprise a dozen series-connected 200-W modules, or roughly 864 cells connected in series. The virtues of this arrangement are (1) that the system’s conductive losses are well managed because the array output current is no higher than that o...

Reconfigurable photovoltaic (PV) systems are of great interest with respect to system designers in order to improve the system’s efficiency and operation. This paper proposes an adaptive reconfiguration scheme to reduce the effect of shadows on solar panels. A method to capture the maximum power point of the photovoltaic (PV) array systemwith the help of DC/DC central converter system is presen...

This paper presents the simulation model of a 3.5 kW PV array followed by a boost converter, which boost up the output voltage of the PV array. Maximum power point tracking (MPPT) can effectively improve the solar energy conversion efficiency of PV array, in this paper perturband – observe (P&O) algorithm has been used to achieve this function. Grid connected PV system needs a three phase inver...

This paper proposes a three-phase four-wire currentcontrolled Voltage Source Inverter (CC-VSI) for both power quality improvement and PV energy extraction. For power quality improvement, the CC-VSI works as a grid current-controlling shunt active power filter to compensate for harmonic and reactive power of loads. Then, the PV array is coupled to the DC bus of the CC-VSI and supplies active pow...

Due to the non-linear characteristics of photovoltaic (PV) array, PV systems typically are equipped with the capability of maximum power point tracking (MPPT) feature. Moreover, in the case of PV array under partially shaded conditions, hotspot problem will occur which could damage the PV cells. Partial shading causes multiple peaks in the P-V characteristic curves. This paper presents a hybrid...

−This paper presents a new approach for efficient utilization of building integrated photovoltaic (BIPV) systems under partial shading conditions in urban areas. The aim of this study is to find out the best electrical configuration by analyzing annual energy generation of the same BIPV system, in terms of nominal power, without changing physical locations of the PV modules in the PV arrays. Fo...

Abstract: In this study, the design and simulation of a combination of a photovoltaic (PV) array with an alkaline electrolyzer is performed to maximize the production of hydrogen as a reliable power resource. Detailed electrical model of PV system, as long as thermal and electrochemical model of electrolyzer is used. Since an electrolyzer is a non-linear load, its coupling with PV systems to ge...
