An analysis of temperature distribution in solar photovoltaic module under various environmental conditions

Abstract

The operating temperature of the photovoltaic module is an important issue because it is directly linked with system efficiency. The objective of this work is to evaluate temperature distribution in the photovoltaic module under different environmental conditions. The results shown that photovoltaic module operating temperature depends not only on the ambient temperature or solar radiation dependent but also depends on wind speed and wind direction. It is presented that the mounting conditions which are not taken into consideration by most of the literature models also play a significant role in heat transfer. Depends on mounting type an increase in module operating temperature in the range 10-15oC was observed which cause further PV system efficiency decrease of about 3.8-6.5 %.

Performance evaluation of online open-circuit voltage estimation method for photovoltaic system

“…The operating temperature of PV panel depends upon many factors such as environmental temperature, irradiation, wind speed, wind direction, tilt angle, and mounting conditions of PV panel [20]. Many researchers proposed different techniques to determine the PV panel's operating temperature.…”

“…In [22], authors present an infrared imaging technique but due to infrared camera, this is an expensive method. The above-mentioned issues can be addressed by using the temperature sensor [20]. In this work, digital waterproof DS18B20 temperature sensor is used to estimate the temperature of PV panel due to its low cost and accurate results.…”

Impact of dust and temperature on energy conversion process in photovoltaic module

“…Also, they conclude that the cell temperature and humidity effect decrease when the wind speed increases. An analysis of the available literature from around the world [14][15][16] which takes into account the module type, geographical region as well as the duration of dust deposition shows that considerable PV module performance variations depend on exposure time. However, most of the studies report energy-yield loss versus exposure time without the detailed information about dust concentration density, and this precludes direct linking of local pollution condition with the PV efficiency loss [17][18][19][20][21].…”

Investigation of orientation impact on electrical power of bifacial solar elements

“…Obviously, the radiation is related to the orientation of the SE relative to its radiation source. Bifacial irradiation affects the energy balance by changing the operating parameters of SE: operating temperature and power generation, which are known to be interdependent [4,5].…”

“…Analysis of recent research and publications. Considerable attention is paid to the study of temperature conditions of solar elements [3][4][5][6][7]. Existing models for determining the energy performance of solar elements are based on the idea of one-facial frontal irradiation of the device.…”
