The performance of photovoltaic (PV) systems is highly dependent on environmental conditions. Due to probable changes in environmental conditions, the real-time control of PV systems is essential for exploiting their maximum possible power. This paper proposes a new method to track the maximum power point of PV systems using the moth-flame optimization algorithm. In this method, the PV DC-DC co...

Abs t r ac t . The number of non isomorphic solutions of the eikonal equation can be infinite. We show that there can exist a whole family of non isomorphic solutions, indexed by a continuous parameter. This implies, first, that the general problem of shape from shading can be ill-posed when no additional condition on the shape is imposed. This is in contradiction with what is sometimes stated ...

This paper presents a method to generate dynamic shading of image-based objects without geometric models. Since conventional rendering techniques cannot be used to render the shading of this type of objects, image processing operation, such as interpolation or combination of image data, is performed. However, the variation of the shading of objects is not linear. Therefore, complicated processi...

The development of robotics technology today has developed rapidly. Many types work that are done can be with robots, especially if the a high level accuracy. One jobs require precision and accuracy is cleaning solar cell module. To get maximum continuous energy from sun, cleanliness module must always maintained. Partial shading such as muddy dusty results in reduced electrical power generated...

A series of measurements showed that community greening and trees shading had different degree of cooling effect. The cooling effect of wall greening was related to factors such as heat storage capacity and the orientation of the wall, climatic conditions. As compared to the heat reduced by sheltering the solar radiation, the heat absorbed by plant transpiration had greater cooling contribution...

This experiment discusses the effect of variability solar radiation due to partial shading and surface temperature PV Panel on output power 100 Wp panels. study begins by determining load system, i.e. DC pump in nutrient circulation system DFT hydroponic system. From there, we can observe change panel shade. survey method actually measures intensity a panel, tools used are thermal sensors measu...

Abstract Tracking the maximum power point is a critical issue with solar systems. The output of panel varies due to variations in irradiance and temperature. Nonuniform irradiation partial shading conditions has direct impact on characteristics photovoltaic (PV) To build diversity tracking algorithms PV systems, this work focuses perturb observe, incremental conductance, fuzzy logic control met...

Partial shadowing is one of the problems that are always faced in terrestrial applications of solar photovoltaic (PV). The effects of partial shadow on the energy yield of conventional mono-crystalline and multi-crystalline PV modules have been researched for a long time. With deployment of new thin-film solar PV modules in the market, it is important to understand the performance of new PV mod...
