Effect of Glass and Plastic Covers on the Performance of Solar Photovoltaic Cells in the Presence of Mud

Abstract

With climate change resulting from the use of fossil fuel sources and the increasing use of energy, the sources of renewable energy is growing interest in, which includes direct use of the radiation from the sun through photo-voltaic cells. Photovoltaic solar cell covers in Sudan are exposed during the year to many environmental factors such as rainfall and dust accumulation in summer, autumn and winter, which weaken the performance of solar cells, as well as the shades of trees and tall buildings which affect the efficiency of these cells in the morning and afternoon. This paper aims to evaluate the effect of mud on the performance when one use glass and plastic covers for solar photovoltaic cells . Four different covers were installed on the photovoltaic solar cells, namely polycarbonate (PC), polymethylmethacrylate (PMMA), solar glass and ordinary glass for a study to assess their quality for resistance to mud. Experimental work shows that the drop rate of the maximum power and the drop rate of efficiency are 47%, 60%, 49%, and 46% for PC cover, PMMA cover, solar glass cover, and classic glass cover respectively. Thus it is not recommended to use PMMA coating as mud insulation for solar photovoltaic cells.

What are sustainable plastics? A review of interrelated problems and solutions to help avoid unintended consequences

“…Alternative materials may not be as good at preserving food, may be more expensive, and not necessarily more sustainable (Systemiq 2022, Williams andRangel-Buitrago 2022). Plastics also contribute to renewable energy production: plastic wind turbine blades are light and can turn fast; plastic is used in PV panels, for instance to protect solar cells from environmental factors (Fan 2021, Ali Elamin andOsman Khairy Ahmed 2022, Majewski et al 2022). Vehicles incorporate many lightweight plastic components that can reduce fuel consumption compared to heavier materials which could be used in car and aircraft components (Klemeš et al 2021, Schirmeister andMülhaupt 2022).…”

Plástico versus vidrio: una visión del ciclo de vida de los dos materiales controvertidos

“…Today, plastic bottles made of PET are widely replacing heavy and fragile glass bottles, offering reusable containers for mineral water and other beverages. According to the British Plastics Federation, more than 70% of soft drinks on the world market are packed in plastic bottles, and only 30% of that is packed in various other packaging materials, such as glass bottles, metal cans, and pressed paper [21], [22].…”
