چکیده

The optimal location and orientation of a photovoltaic array is not sufficient to produce the maximum energy generation. The shadows are responsible for power losses. These can be reduced by the following: changing the type of PV cell used, the configuration of the bypass diodes, and also the dimension or the limits of adjustment in the MPP inverter search. In this paper, different scenarios have been simulated to compare and demonstrate the importance of the PV modules layout to minimize the power losses.

An Investigation of Temperature Effects on Solar Photovoltaic Cells and Modules

The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...

A Hybrid Switching Technique for Single-Phase AC-Module PV System to Reduce Power Losses and Minimize THD

This paper proposes a hybrid switching technique for a domestic PV system with AC-module architecture. In this PV system, independent control of PV modules, which are directly connected to DC terminals of a single-phase cascaded multilevel inverter, makes module-level MPPT possible to extract maximum available solar energy, especially in partial shading conditions. As one of the main contributi...

Optimal Reconfiguration of Solar Photovoltaic Arrays Using a Fast Parallelized Particle Swarm Optimization in Confront of Partial Shading

Partial shading reduces the power output of solar modules, generates several peak points in P-V and I-V curves and shortens the expected life cycle of inverters and solar panels. Electrical array reconfiguration of PV arrays that is based on changing the electrical connections with switching devices, can be used as a practical solution to prevent such problems. Valuable studies have been perfor...

Fuzzy-Decision-Making Predictive Power Control Approach to On-Grid Photovoltaic Panel

In this paper, a voltage-current mode controller is proposed to adjust both the input current and DC voltage of a boost-inverter in order to improve the performance of the photovoltaic (PV). The proposed system is based on fuzzy-making-decision predictive voltage-current controller (FPVCC). The simulation results show that in case of using the proposed FPVCC, the input current of a PV array is ...
