Solar power is an alternative energy source that can be used for cooking. It is a simple, secure, and useful way to cook food without using conventional fuels that pollute the air. Solar cookers offer various benefits to the user’s health, productivity, and income as well as to the environment. Solar energy is abundant in a tropical country like Indonesia, making it a dependable and sustainable of energy resource. The study’s goal is to analyze the potency of steam produced by a solar cooker that uses a Fresnel lens concentrator. The thermal performance of the Fresnel lens concentrator with a conical receiver on the solar cooker prototype is discussed in this research. In the construction of solar cookers, PMMA (Polymethyl-Methacrylate) Fresnel lenses, manual trackers, and conical receiver types are used. The research conducts an experimental analysis of the thermal performance of the prototype solar cooker using a Fresnel lens concentrator with a conical receiver. This empirical approach provides valuable data on the efficiency and effectiveness of the solar cooker design. The experiment result shows the cumulative average solar irradiation, the average collection of solar energy per time of Fresnel lens concentrator, and the heat utilized of steam from conical receiver are 709.09 W/m², 456.14 Watt, and 383.88 Watt, respectively. The results of this study suggest that Fresnel lens concentrators are a promising development for indoor solar cookers and therefore provide a pathway for increased utilization of solar cooking technology.

“…Furthermore, Fresnel lens collectors produce higher temperatures than flat plate collectors due to their higher light concentration and lower heat loss [17]. 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].…”

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.

Solar energy has great potential for utilization as an unlimited and alternative renewable energy source that can be stored in batteries and used to drive the BLDC motor on electric bicycles. The purpose of this study was to determine the charging efficiency of a 100 Wp solar panel mounted on an electric bicycle. A solar power meter was used to measure the solar radiation absorbed by the photovoltaic (PV) module, while sensors were used to measure the current and voltage (DC) output from the solar panels. The sensor signals were then processed by a micro controller and displayed on an LCD screen, as well as recorded by an SD card data logger. The characteristics of the charging voltage were compared with and without the PV module. The results showed that at a solar radiation of 1008 W/m², the maximum voltage and current achieved were 17.49 V and 3.37 A, respectively. Under these conditions, the battery charging efficiency of a 100 Wp solar panel was 58.94%. A one-hour test with an average solar radiation of 976.3 W/m² showed that integrating a 100 Wp PV module increased the energy stored in the e-bike battery by 33.33%. Therefore, the hybrid solar e-bike concept has the potential to improve the performance of electric vehicles in the future.
