“…Figure 3 shows a cross-section of the solar panel as well as its thermal resistance network. The solar energy irradiating the solar panel Q C is divided into two parts [21,31]; the useful energy and the thermal losses. The first part, i.e., the useful extracted energy, generates electrical energy Q el according to the following expression:…”

“…The decrease in temperature achieved by the heat sink results in an increase in the open circuit voltage Voc and maximum power Pmpp by 10% and 18.67%, respectively. In [21] a steady state analysis of solar radiation falling on the solar panel surface was performed to obtain the amount of useful energy as well as thermal energy losses. The present work studies the effect of attaching an aluminum heat sink to the solar panel back surface to enable the heat transfer by conduction from its base to the heat sink base plate and fins and then to the surrounding air.…”

“…The present work studies the effect of attaching an aluminum heat sink to the solar panel back surface to enable the heat transfer by conduction from its base to the heat sink base plate and fins and then to the surrounding air. The mathematical model used here is based on the one that was derived in [21]. However, the studied structure is modified to include the wind speed variation that could be due to movement of vehicles on the road when this model is applied for pole mounted solar panel of a street lighting system.…”

“…Design and selection of heat sink are also addressed in order to reduce the operating temperature of the solar cell. Therefore, the original study in [21] is extended here to provide the gained energy due to the proposed system of pole mounted solar panels by effective cooling using aluminum heat sink under hot weather and variable wind speed environment.…”

The increase in operating temperature of PV generators leads to degradation of their performance. These adverse effects of high temperatures are considered as one of the most important problems that solar panel operation faces in hot weather areas. A lot of research has been undertaken to study this aspect and find ways of limiting the harm caused by such high temperatures. To overcome this harm and to maintain the operating temperature of the PV cells within the optimum range specified by manufacturers, cooling the solar panels often becomes indispensable. This paper discusses the heat transfer through the solar panel layers and studies the effect of high temperature on the solar panel performance in a hot desert environment. It also presents the development of a new solar panel structure viz. by installing an aluminum heat sink to reduce the effect of temperature rise and thus improve the solar panel performance. The study focuses on a pole-mounted solar panel for a street lighting apparatus in extremely hot desert conditions with fluctuating wind speeds. It will be shown that adding an aluminum heat sink to the solar panel bottom mitigates the effect of increased temperature and hence modifies the solar panel operating point by increasing both the efficiency and the lifetime. The solar cell temperature is decreased by 16.4% as a result of the aluminum heat sink installation on the solar panel back sheet and consequently, the accumulated energy produced by the the solar panel is increased by 13.23% per day.
