Experimental Analysis of Factors Affecting the Power Output of the PV Module
International Journal of Electrical and Computer Engineering (IJECE), 2017
Energy is the driving force in all the sectors as it acts like an index of standard of living or prosperity of the people of the country. However heavy dependence on fossil fuels leads to global warming, hence there is a need for the use of clean, sustainable, and eco friendly form of energy. Among the various types of non-conventional energy solar energy is the fundamental as it is abundant, pollution free and universally available.Even though the main input to the PV system is the solar radiation still there are other factors which affects the efficiency of the pv module. In this paper real time experiment has been conducted to analyze the effect of various factors like irradiance, temperature, and angle of tilt, soiling, shading on the power output of the pv module. Temperature is a negative factor which reduces the efficiency of the module and can be reduced by various cooling arrangements. Presence of dust particles and shading obstructs the incident solar radiations entering the panel and the effect is seen in the iv and pv curve .For better performance solar tracking at maximum power point is suggested to improve the power output of the pv module.
In the present study, experimental investigation of effect of environmental variables on performance of solar photovoltaic module has been conducted. The experiments were performed at 100 kW rooftop solar power plant and the research laboratory of Mechanical Engineering Department at Poornima University, Jaipur, India (Latitude: 26 0 55" and Longitude 75 0 46"). An experimental investigation was carried out to specifically evaluate the performance of 300W Polycrystalline Solar Photovoltaic (PV) module under various environmental factors such as dust, temperature, humidity, altitude, vegetation, ground type etc. The outcome of test results indicates that every variable has considerable amount of impact on the performance of solar photovoltaic module. This paper elaborates the investigation methodology, outcome under different set up conditions and the results have been discussed in this paper. It has been observed that various small measures related to environmental issues ...
Sustainable Energy Research
One of the biggest causes of worldwide environmental pollution is conventional fossil fuel-based electricity generation. The need for cleaner and more sustainable energy sources to produce power is growing as a result of the quick depletion of fossil fuel supplies and their negative effects on the environment. Solar PV cells employ solar energy, an endless and unrestricted renewable energy source, to generate electricity directly. The optimum output, energy conversion efficiency, productivity, and lifetime of the solar PV cell are all significantly impacted by environmental factors as well as cell operation and maintenance, which have an impact on the cost-effectiveness of power generation. This article presents an analysis of recent research on the impact of operational and environmental factors on the performance of solar PV cells. It has been discovered that temperature and humidity, combined with dust allocation and soiling effect, have a significant impact on the performance of...

The effects of various environmental factors have been studied on the efficiency of the PV module as an essential part of the work and how to enhance its efficiency by reducing the influences environmental factors. The study deals with the efficiency of PV module and how to calculate and improve them. The measurements were made from December 2020 to August 2021 at 9 am to 5 pm for the weather of the city of Nasiriyah. The examination a single PV module is used, which gave an PMAX equal to 10 Watt. The most important has been studied on the PV is the temperature, whenever its grateful that led to decline in the output voltage and slight decrease in the output current. The output current PV module increased when the rise in the solar irradiance. To mitigate the impact of this factor, air cooling and water cooling had been used through cooling techniques by using DC fan, cooling blocks and water douche. It is clear that from our work we have improve efficiency of the module during the ...
Investigation the factors affecting on the performance of PV system
1ST SAMARRA INTERNATIONAL CONFERENCE FOR PURE AND APPLIED SCIENCES (SICPS2021): SICPS2021
The photovoltaic (PV) panel is a semiconductor device that generates electrical energy when the light falls on it. Many factors affecting badly on the performance of the PV system. In this research, the influence of dust, clouds, shades, and car exhaust smoke on the performance of the PV panel had been investigated. It has been found that the dust and shade had a bad influence on the efficiency of the PV panel. The efficiency decreased from 9.14% to 3.19% at midnight, when the solar radiation is at its peak. Whereas, the clouds & heavy exhaust smoke of cars, the efficiency decreased to 4.66% & 3.99%, respectively.
Improving the performance of the photovoltaic panels
There are many factors that affect the performance of photovoltaic (PV) panels, e.g. (i) dust accumulation on PV panels, and (ii) overheating of the panels. Dust accumulation on PV panels, especially in desert areas, can obscure the solar radiation, and therefore reduce the efficiency of the panels dramatically, as well as heating of PV panels due to excessive solar radiation and high ambient temperature reduces the efficiency of the panels, significantly. Many studies have been carried out to solve dust deposition and overheating of solar panels separately, however, none of them was done to solve both problems at the same time. The main objective of this research is to solve the problems of dust accumulation and overheating of PV panels at the same time using the minimum amount of water and energy. These two issues, i.e. dust accumulation and overheating, are tackled by developing a system that can clean the PV panels from deposited dust, and at the same time cools the panels. The ...

This study compares the manufacturer's technical data of several PV modules with real measured outdoor technical data. The irradiance effect on several PV modules is examined by the changing a tilt angle and comparing different meteorological situations of sky clearness (clouds) on the modules mounted outdoor and exposed to Sun. Also, the influence of temperature and dust on the performance of a PV panel is under research using measurement methods described in the paper. The measured current and voltage data at the clean surface of the PV module correspond to the declared data of the PV module manufacturer, and in the case of fouling of the module surface with dust, a power drop of 7.39% was measured.
Effect of Wind Speed and Temperature on the Efficiency of PV Module
Nowadays Energy Supply has become a major issue for developing countries like Pakistan. To cope up with this issue the world starts moving towards renewable sources instead of burning fossil fuels which has a carbon effect on the environment as well as living things. In the Power Generation sector, Solar Energy has now become an alternative to Fossil Fuels based power production plants. In today's world, PV modules known as Photovoltaic Modules consisting of different solar light-capturing sheets are used to get safe energy production. Side by side, calculation, and analysis of the impact of various factors like wind and temperature on the production of energy are significant for the evaluation of capacity.
