Abstract:

Partial shading in solar photovoltaic arrays reduce the maximum power produced. Partial shading conditions in PV arrays can be caused by water, dust, tree shadows, bird-drops, nearby building, etc. Special configuration is needed to reduce the effect of partial shadings. In this study, 8 × 8 symmetric photovoltaic arrays configured in different configurations such series-parallel (SP), total cross-tied (TCT), modified complementary sudoku puzzle (MCSDKP) and symmetric matric total cross-tied (SMTCT) are studied under row shading of 25% shaded area and 50% shaded area with two different shading

Abstract:

This study scrutinizes the reliability and validity of existing analyses that focus on the impact of various environmental factors on a photovoltaic (PV) system’s performance. For the first time, four environmental factors (the accumulation of dust, water droplets, birds’ droppings, and partial shading conditions) affecting system performance are investigated, simultaneously, in one study. The results obtained from this investigation demonstrate that the accumulation of dust, shading, and bird fouling has a significant effect on PV current and voltage, and consequently, the harvested PV energy

Abstract:

A Solar panel is rated such that it can yield optimum output under Standard Testing Conditions (STC). But due to different environmental factors the efficiency of the panel is reduced gradually after installation. Accumulation of dust on solar PV panel is one such natural phenomenon. When dust accumulates on the PV panel, the temperature of the cells increases which subsequently decreases the open circuit voltage. The short circuit current is also reduced as deposition of dust causes shading on the panel surface. As a result, the output power of the module decreases. In this paper, the effect

Whole slide imaging (WSI) refers to the process of creating a high-resolution digital image of a whole slide.

A shading correction method for brightfield WSI is presented, which is simple but robust not only against typical image artifacts caused by specks of dust and bubbles, but also against fixed-pattern noise, or spatial variations in pixel values unde

Abstract:

One of the major concerns for continuous solar photovoltaic (PV) generation is partial shading. The movement of clouds, shadow of buildings, trees, birds, litter and dust, etc., can lead to partial shadow conditions (PSCs). The PSCs have caused inconsistent power losses in the PV modules. This leads to a shortage of electricity production and the presence in the PV curve of several peaks. One of the simplest solutions to PSC’s is the PV configurations. The objective of this paper is modelling and simulation of solar PV system in various shading scenarios for KC200GT 200 W, 5 x 5 configurations

Abstract:

Maintaining the maximum performance of solar panels poses the foremost challenge for solar photovoltaic power plants in this era. One of the common PV faults which decreases PV power output is a hot spot which is caused by a prolonged local partial shading from objects, such as dust piles or animal waste. To prevent it, an enormous effort for PV inspection is needed especially for large solar power plants. Hence, automatic partial shading detection is critical in preventing PV hot spots to assist maintenance activities which are associated with a drop in energy output. This research developed

Traditional monitoring methods rely on ground-based sensors and periodic cleaning schedules, which may not effectively address real-time soiling dynamics. This research presents an AI-powered approach using YOLOv10 to label and train satellite imagery for the detection of dust accumulation, cloud cover, and other obstructions affecting solar radiation reaching PV systems. By integrating deep learning with multi-temporal satellit

Abstract:

Photovoltaic is used to convert electricity from solar radiation. The working characteristics of photovoltaic depend on environmental conditions such as temperature, solar radiation intensity, and the surrounding environment. During operation, the photovoltaic generation system (PGS) can be partially or completely shaded due to natural phenomena such as clouds, buildings, dust, animals, electric pillars, trees ... these are changing the characteristics of the system’s power output of PV. This paper proposes a maximum power point tracking algorithm for PGS operating under partially shaded condi

Abstract:

The solar photovoltaic (PV) energy is the most prevalent and popular source of energy. But the PV output characteristics are mainly depending on temperature and irradiance and are nonlinear in nature. Therefore, PV array characteristics greatly vary with change in the atmospheric condition. Under partial shading condition (PSC), PV modules will not receive the same level of incident solar irradiance throughout the system due to some obstructions such as: dust, cloudy weather, shadows of nearby objects: buildings, trees, mountains, birds etc… which causes mismatch in PV module characteristics o

Dust accumulation on solar photovoltaic (PV) modules reduces light transmission from the outer surfaces to the solar cells reducing photon absorption and thus contributing to performance reduction of PV systems. In regions such as the Middle East where dust is prevalent and rainfall is scarce, remedial measures are needed to reduce such impacts. Currently, various techniques are being employed to address such sand soiling ranging from mechanical (brushing) to active and passive electrical interventions.

Abstract:

Solar energy has been one of the most promising energy sources since the 1990s. However, the efficiency of solar panels is reduced due to dust accumulation over modules, which blocks the incident light from the sun. The efficiency of a solar panel depends on various factors, such as the quality of the solar cells, the design of the panel, the temperature and intensity of the sunlight, and the presence of any shading or obstructions. High-efficiency solar panels can produce more electricity from the same amount of sunlight, resulting in higher energy production and cost savings over the system’

Abstract With the increase in energy demand, the necessity for photovoltaic panels to be as efficient as possible has also increased. In order to achieve the highest possible performance, solar cells depend on a number of environmental elements such as: temperature, shading, cloudy weather, deposits on the surface, dust, solar irradiation, nighttime darkness, etc. All these factors ultimately result in a decline in photovoltaic panels performances.
