Special Issue Information

Dear Colleagues,

Nowadays photovoltaic (PV) grid parity is a reality in many countries of the world, while fuel parity is happening in those countries with high levels of solar irradiation. This trend has been driven by public subsidies given worldwide and by huge investments in the R&D. Nevertheless, the efficiency of PV plants can still be improved working both on their reliability and on new PV technologies. With reference to these latter, researchers are studying new materials (e.g. perovskite solar cells) and new technologies to capture more solar irradiation (e.g. bifacial PV modules). With reference to the system efficiency, researchers are studying the possibility to cover reservoir with PV fields on floating structures in order to limit the temperature losses and increase the albedo. New diagnostic strategies are also foreseen as a tool of paramount importance in order to increase the efficiency of PV systems. Among these, unmanned aerial vehicles (UAV) equipped with visible and infrared cameras are just an example of new tools used to obtain useful information regarding the performance of PV modules in big solar parks. This Special Issue aims at collecting original research or review articles on the modelling of new PV devices, systems, and diagnostic strategies.

With the energy crisis and the constant blackout in the Mozambique Power Company grid, the option of applying solar photovoltaic (PV) systems has been one of the most used alternatives in the neighborhoods of the Maputo region. However, inefficient power delivery caused by unproper sizing and installation of stand-alone solar PV systems has been contributing to the low utilization of solar energy potential in the Maputo region. The optimal sizing and installation of the solar PV system is addressed to evaluate the influence of installation and operation parameters on the power output of PV modules. In this topic, PV modules parameters such as cell temperature, the module’s slope and azimuth angles, the losses caused by excessive heating of the module cells, shadows and dust on the PV module and the cooling process at the back of the module are assessed in order to find out the consequence of inadequate installation and operation parameters of solar PV systems in the Maputo region. The proper sizing and installation of the stand-alone solar PV system is fundamental to guarantee the continuous and efficient supply of power and, thus, different tools and techniques have been applied. This study will deal with the hybrid optimization of multiple energy resources (HOMER) and system advisor model (SAM), to size and improve power generation of solar PV systems. This study concluded that for the Maputo region, the optimal tilt angle is 23 ± 2° and the azimuth angle is 11 ± 2°. In addition, for optimization of the tilt and azimuth angles, it also examined the effect of module backside ventilation and proved that the system’s power generation increases with the rise of spacing between the module and the wall, since the strategy prevents the decline of the module cells efficiency. However, the maximum recommended spacing between the PV module and the mounting wall is about 0.4 m, since an effort to increase the spacing up to this level results in an insignificant growth of power output.
