“…These parameters include location, operating temperature, radiation level, radiation spectrum, wind speed, angle of incidence and several other factors. This causes the actual efficiency to differ from the efficiency measured in the manufacturer's manual [11]. Several factors that affect the performance parameters of PV Modules include surface area, solar radiation, ambient temperature, weather, and other factors.…”

The article discusses the efficiency analysis of the Photovoltaic (PV) modules, namely polycrystalline and amorphous. The performance in question is the instantaneous efficiency obtained from the measurement of the voltage (V) and current (I) data generated by the two PV modules. In addition, it aims to determine the effect of solar radiation on the output power of polycrystalline and amorphous PV modules. The research was conducted in September 2020, with the outdoor location of the Department of Mechanical Engineering, State Polytechnic of Malang (7,944 °S; 112,613 °E). The independent variables in this study are the current and voltage generated, and the type of PV Module (Polycrystalline and Amorphous). The dependent variable in this study is the actual power and instantaneous efficiency. Measurement of solar radiation using the Glentest SM 206 Solar Power Meter. Measurement of Current and Voltage using a Digital V-I Meter. The results showed that the greater the solar radiation, the higher the actual power and efficiency generated by the PV Module. Polycrystalline PV Modules are capable of producing higher average actual power and average instantaneous efficiency, which are 86.83 W and 11.92% when compared to Amorphous PV Modules, which are 43.88 W and 6.01%.

“…However, according to the author [17], nowadays the application of solar thermal energy concentrators is still dominated by the reflective method of mirrors in the form of a parabolic trough collector, linear Fresnel reflector (LFR), parabolic dish, and central receiver. One of the weaknesses of this model is that the material is heavy, so it needs a sturdy framework, so it is not economical.…”

Energy-saving technologies and equipment 31 in Indonesia comes from fossil energy sources. Until 2019, power plants in the country are still dominant from conventional energy sources, including coal (50 %), followed by natural gas (29 %), fuel (7 %). While the use of renewable energy is only about 14 %, and for solar energy, utilization is less than 1 % [1]. Currently, the largest energy user in Indonesia is the industrial sector by 36 %, the transportation sector by 40 %, the household sector by 16 %, and the commercial sector by 6 %. 1. Introduction Solar thermal energy is one of the potential energy to be managed and developed further as a source of energy reserves, especially for countries located on the equator, including Indonesia, where the sun shines throughout the year. The potential of solar power in this region can reach 5.1 kWh/m 2 /day (Eastern Indonesia) and 4.5 kWh/m 2 /day (Western Indonesia). However, the majority of energy use

“…A study conducted by Asrori and Susilo [18] using a Fresnel lens to heat 2 liters of water found a temperature of around 70 °C, but they did not report the type of absorber used. Furthermore, the Fresnel lens application also has the potential to be used for steam generation [19] and solar cookers [20]. Moreover, Rashid et al [21] reported in their review study that Fresnel lenses have broad applications such as photovoltaics, solar stills, solar thermal collectors, solar sterilization, solar cookers, and solar-pumped lasers.…”

The development of cost-effective and environmentally friendly solar thermal technologies that deliver high performance poses several challenges, where the collector and absorber components play a pivotal role. This research addresses these issues by investigating enhanced temperature generation using a 30 cm × 30 cm Fresnel lens collector under solar illumination from a xenon lamp. Natural stone materials (andesite, coal, and pumice), characterized by granular structures with an average diameter of 1.68–2.00 mm, were selected because of their abundance and eco-friendliness. This research is focused on evaluating the effect of Fresnel lens on temperature generation performance. Two types of temperature generation tests were carried out: wet tests (where the natural stone materials were immersed in distilled water) and dry tests (where the natural stone materials were used in dry conditions). The morphologies of the natural stone materials were examined using an optical microscope and scanning electron microscope. Furthermore, the optical properties of the natural stone materials were analyzed using an ultraviolet–visible (UV–VIS) spectrophotometer. The findings revealed that there were significant improvements in the photothermal absorber performance with the use of a Fresnel lens in dry tests, where the highest temperature was achieved for coal (103.25 °C), followed by andesite (89.00 °C) and pumice (73.00 °C). The impurities varied between the materials, where the impurities were most dominant for pumice while coal was more uniform. Further examination using scanning electron microscope showed that all materials had light-trapping structures in the form of rough surfaces, pores, and crack gaps. Andesite was dominated by rough surfaces, while coal and pumice were dominated by crack gaps and pores, respectively. However, based on the UV–VIS spectrophotometric results, there were no correlations between the optical properties (absorbance, reflectance, and transmittance) and temperature achieved by the photothermal absorber materials. This research demonstrates the potential of using natural stone materials as photothermal absorbers in combination with a Fresnel lens collector for low-to-medium temperature solar thermal applications.
