Photovoltaicpanels are used to generate electric power. The surface temperature of the photovoltaic (PV) panels will affect theirefficiency,where the increment of temperature will decreasetheir efficiency and total power gain. In this study, we will discuss the performance of an 80 W floating photovoltaic (PV) panel in a pond simulator, whereby in a two hour experiment it shows up to 15.5% increment of energy gain compared to a normal photovoltaic (PV) panel. The floating photovoltaic (FPV) panel was designed by replacing the photovoltaic panel frame with a material that has the ability to float on a water surface and is capable of transferring heat at the back of the photovoltaic surface. A heat sink is used to transfer heat at the bottom of the photovoltaic panel, which will decrease the surface temperature when placed on the water surface. The best performance of the photovoltaic panel is 1000 W/m 2 fora surface temperature of 25°C; however,the efficiency will drop by 0.485% per1°C temperature increment.The system can be used on lakes, ponds or dams.

Abstract. In this paper, several attempt were made to investigate the best electrical performance of a floating photovoltaic (FPV). In photovoltaic (PV) system, the electrical efficiency of the system decreases rapidly as the PV module temperature increases. Therefore, in order to achieve higher electrical efficiency, the PV module have to be cooled by removing the heat in some way. This paper presents study on a conventional photovoltaic (PV) module and floating photovoltaic (FPV) system. The objective of the study is to compare the performance of conventional PV module and FPV. At FPV, an absorber comprises of aluminum flat-box housing was attached to the back of the PV module to absorb heat. Water is used to cool the PV module by passing it under the bottom surface of the module. The system was tested under simulated solar intensity of 417 W/m 2 , 667 W/m 2 and 834 W/m 2 . Current (I) -voltage (V) curves and power (P) -voltage (V) curves of the results were analyzed. The study found that the FPV has higher efficiency and total power gain than the conventional PV module. The average PV temperature in a FPV might be lower than that for a conventional PV module, thereby increasing its electrical power output. The simplicity of the system structure and aluminum as the chosen material enabled it to reduce the installation costs for a larger scale. Applicable as heat sink, this FPV system is convenient to place on lakes, ponds or rivers.

The purpose of this study is to design and develop a Solar Energy STEM module (SESTEM) among a class of 80 diploma science students in the Faculty of Science and Mathematics, Universiti Pendidikan Sultan Idris (UPSI). This module was developed to create an enjoyable technology-embedded learning process for solar energy education. The students’ perceptions evaluations of the complete SESTEM module were based on questionnaires and open-ended questions. The module implements fully hands-on activities using smartphones, QR codes, images, and videos. This work was based on the Analysis, Design, Development, Implementation, and Evaluation (ADDIE) instructional model. The findings showed that students gave positive feedback regarding the contents and the activities implemented in the module. In conclusion, SESTEM can be considered a modern teaching tool, enhancing more value-added skills and being accustomed in the future
