The significant research interest in the engineering of photovoltaic (PV) structures at the nanoscale is directed toward enabling reductions in PV module fabrication and installation costs as well as improving cell power conversion efficiency (PCE). With the emergence of a multitude of nanostructured photovoltaic (nano-PV) device architectures, the question has arisen of where both the practica...

Solar power represents a vast resource which could, in principle, meet the world's needs for clean power generation. Recent growth in the use of photovoltaic (PV) technology has demonstrated the potential of solar power to deliver on a large scale. Whilst the dominant PV technology is based on crystalline silicon, a wide variety of alternative PV materials and device concepts have been explored...

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...

The research focused on the experimental evaluation of Photovoltaic (PV) – green roofs under Mediterranean climate summer conditions. Two autochthonous plants, Gazania rigens and Sedum clavatum, were selected for the PV-green systems while a PV-gravel configuration was used as the reference roof. The above mentioned roofing systems were developed and tested at the University of Lleida, in Spain...

The modeling and simulation of photovoltaic power generation system has become an important issue in the field of power generation. Research on the characteristics of photovoltaic (PV) grid-connected system by hardware-in-the-loop simulation could provide convenient experiment condition and accurate result. This article designs a photovoltaic grid-connected simulation platform for digital/physi...

This paper shows the analytical performance of maximum power point tracking for a photovoltaic system. In contemplation for photovoltaic (PV) systems to escalate their efficiency of power generation, it is mandatory to locate the Maximum power point (MPP) under all possible illumination conditions. The current-voltage (I-V) characteristics of PV devices are non-linear in nature, thereby the , M...

Renewable energy sources, like wind and photovoltaic (PV) power plants can be used to provide grid-friendly services in the form of additional active and reactive control for frequency and voltage regulation respectively. Current wind and PV power systems are operated in simply an energy supply mode and are not required to participate in ancillary power services. These services will become crit...

unlike traditional power grids, smart grids have the advantage of bidirectional power flow and having distributed generations. distributed generation systems are usually supplied by renewable sources which can cause unpredicted voltage fluctuations as a result of being intermittent. while traditional compensating devices deal with the problem of voltage fluctuation and reduced power quality wit...

Photovoltaic system (PV) is alternate suitable option against conventional source of generating electricity. A typical photovoltaic system produces the electrical energy in terms of voltage and current. PV system is the environmental protection technique as well as saving of the electrical energy. This system reduces the level of chlorofluorocarbons (CFC) in the environment because it restricts...

This Paper presents Maximum Power Point Tracking (MPPT) of Photovoltaic Array under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic. A good number of publications report on different MPPT techniques for PV system most of th...
