“…This study used experimental methods to produce the temperature distribution at the top and bottom of the panel, then used as heat input for the simulated thermoelectric generator module. The solar panels are conditioned to resemble the roof of a house with a slope of 20 degrees [21]. This replica of the roof of this house is placed in an open rooftop area close to the six engineering faculties building, Universitas Sebelas Maret (7°33'49.1"S 110°51'19.0"E), Indonesia (Figure 1).…”

The growing demand for energy has an impact on the development of environmentally friendly renewable energy. The sun is energy that has the potential to be used as electrical energy through light energy and heat energy. Recently, research interest related to photovoltaic performance has increased. Several studies have investigated the effect of panel cooling on photovoltaic performance. In this study, the use of exergy solar panels is considered to improve performance by adding a thermoelectric system. Research work related to photovoltaic testing with thermoelectrics at low temperatures has not been carried out. Therefore, experimental methods to obtain temperature profiles and simulation methods to see the power potential generated from thermoelectrics have been carried out. The experimental method is carried out using mono-crystalline panels with type K sensors to retrieve temperature data and data acquisition as deviations from the current, voltage, and temperature results of the panel. The simulation model was carried out using the ANSYS software. Tests are carried out, taking into account the effect of back panel temperature on system performance. The results showed that the photovoltaic temperature fluctuated due to the influence of cloud cover, the highest photovoltaic temperature was 57°C, and the lowest temperature was 30°C. The maximum power produced by photovoltaic is 39.8W. It is then applied to the thermoelectric simulation based on the highest temperature, and the maximum power value is 1673.4 mW. This photovoltaic-thermoelectric generator system produces a 4.2% increase in power value over conventional photovoltaic systems. The findings in this study can be used as a reference for all types of low-temperature photovoltaic-thermoelectric systems. Doi: 10.28991/CEJ-2022-08-07-02 Full Text: PDF

Reduced energy consumption is a direct result of building optimization. Solar panels and heat detectors can provide the necessary power. After years of refinement and development, methods for regulating solar panels' output are finally finding their way into everyday life, where they are having a dramatic impact on the foundations of sustainability. This document provides an up-to-date assessment of several strategies for preventing solar panels from overheating, all of which serve to boost their efficiency and prolong their service life. It begins with a brief background on protection technologies before moving on to a survey of recently filed patent applications that address this topic. The study concludes with a proposed assessment of the strengths and shortcomings of these safeguards. We anticipate that the information included in this review paper will be an invaluable tool for scholars and researchers.

Photovoltaic (PV) panel are crucial in the conversion of solar irradiance into electrical energy. However, the efficiency of PV panel is indirectly influenced by the surface temperature of the panels. According to typical PV module standards, the effect of panel temperature on efficiency is -0.47 %/°C, which indicates that a rise of 1°C reduces the PV panel's efficiency by 0.47 %. The efficiency of the PV panel achieves its maximum value when the panel temperature reaches 25 ℃, which is the standard test condition (STC). Moreover, a high working temperature can also reduce the lifetime of the PV panel. Based on the limitations that have been highlighted above, this project aims to design and develop a hybrid cooling PV panel by using active and passive cooling system with Arduino UNO R3. In this project, 100 W monocrystalline photovoltaic panel has been selected to analyze the result before and after installation of hybrid cooling system. Active cooling system is a water sprinkler system which is applied in front of the PV panel. Meanwhile, the passive cooling system is a combination of hydrogel beads and the heat-sink cooling system which will be installed behind the PV panel. In result, the average power output of PV panel without cooling was 30.59 W while the average power output of PV panel with hybrid cooling was 34.66 W. Moreover, the average power increased due to cooling was 13.31 %. In a nutshell, the proposed project has the ability to develop a hybrid cooling system to improve the performance and efficiency of the PV panel in order to increase the power output of the panel.
