Limited access to electricity and endemic power shortages are huge problems in West African countries, as the lack of sufficient power impedes the socio-economic development in the region. Improving access to and reliability of electricity in West Africa will require close cooperation among neighboring countries, and this was one of the aims for th...

Cyprus continues to be one of the European Union’s most energy import-dependent countries. It is of worthy note that Cyprus is also the only European Union member state whose electricity grid is not connected to the European power network, as it uses an independent network that relies on local production. The high cost of electricity has been ident...

In this study, a 3 kWp grid-connected photovoltaic/thermal system is proposed for a four-person family situated in the Middle Eastern and North African (MENA) region. The performance of the proposed hybrid PV/T system is simulated and compared for the major cities in eighteen (18) MENA countries. Economic and environmental analysis of the hybrid sy...

Clouds, being complex components of the atmosphere, have significant effects on power generation by photovoltaic (PV) systems. For example, shadows caused by the cloud coverage over a geographically distributed PV power plant may cause significant fluctuations in power generation by leaving a number of PV panels unable to generate power and contrib...

This paper proposes a simple and dynamic reconfiguration algorithm for photovoltaic (PV) arrays in order to mitigate negative effects of non-uniform spatial irradiance profiles on PV power production. Spatially dispersed irradiance profiles incident on inclined PV module surfaces at each application site are generated based on real sky images. Mode...

The development of a system for output power estimation and fault detection in photovoltaic (PV) modules using an artificial neural network (ANN) is presented. Over 30,000 healthy and faulty data sets containing per-minute measurements of PV module output power (W) and irradiance (W/m2) along with real-Time calculations of the Sun's position in the...

This paper presents a comparative analysis of Levenberg-Marquardt (LM) and Bayesian Regularization (BR) backpropagation algorithms in development of different Artificial Neural Networks (ANNs) to estimate the output power of a Photovoltaic (PV) module. The proposed ANNs undergo training, validation and testing phases on 10000+ combinations of data...

This paper mainly analyzes the performance of different photovoltaic array configurations under various shading patterns. A Matlab/Simulink based simulation model of a PV module is utilized as the smallest building block of the mentioned topologies. The model is validated using the datasheet parameters of the ‘SOLAREX MSX-60’ PV module. The perform...

This paper mainly focuses on the performance evaluation of "Perturb&Observe" and "Incremental Conductance" algorithms as the most commonly utilized two Maximum Power Point Tracking (MPPT) techniques for photovoltaic systems. Matlab/SIMULINK platform is used to model and simulate the entire system. The simulation model of a PV module is constructed...

This paper proposes a simple and practical simulation model for solar modules using MATLAB/Simulink. The model is based on a single-diode mathematical model of a solar cell and is capable of accurate modeling of I-V and P-V characteristics of a solar module. Model parameters are obtained from manufacturer's datasheets and series and shunt resistanc...

This paper mainly focuses on experimental performance analysis of solar modules under different irradiance values. Also effects of interconnection types and bypass diode application on module output characteristics under variable shading patterns are analyzed.

This paper proposes a simulation model for calculation of the sun`s position in the sky and the incidence angle of sunlight beams on the surface of solar modules with any tilt angle, located at any geographical location on the Earth`s surface. The electrical power generated by a solar panel directly depends on the amount of the received solar irrad...

This paper mainly focuses on methods of calculations of sun`s position in the sky and analyses of its effects on solar panel output characteristics collected during a case study. Methods for calculations of sun`s position in the sky and measurement of solar panel output characteristics are reviewed and then followed by a case study on an experiment...

This paper mainly focuses on the effects of variations of solar irradiance on PV panel power outputs and considers the importance of choosing the right orientation for system installations. The analyses are based on real-time measured data collected during a 6-Month period (October/2012-March/2013) in Northern Cyprus. The mentioned data presents th...

It is basically approved that the output power of a solar cell/module directly depends on the amount of solar irradiance which it receives from the sun. Also it is known that the irradiance values are not constant at any specific time interval. The changes in the position of the sun with respect to earth are one of the main reasons causing the vari...

The main purpose of this paper is on developing an intelligent system which provides real time monitoring and fault detection for solar panels. Utilizing artificial neural network technology, the solar panel fault detection system is capable of perceiving sun’s position in the sky and estimating the corresponding output power of a solar panel based...
