This study aims to analyze the voltage value with the use of a flat mirror reflector equipped with a fan cooling system on the utilization of monocrystalline solar cells in generating electrical energy for a 12 Volt direct current (DC) water pump with a power of 180 Watt. Monocrystalline solar cells were chosen because of their high efficiency in the conversion of solar energy into electricity.…
Solar energy is a source of energy whose availability is unlimited and environmentally friendly. Excessive radiation and high environmental temperatures can cause serious problems such as overheating of solar panels. High temperature on the panel can reduce the output voltage, efficiency, and shorten the life of the solar module. Thus, it is necessary to have a solar panel cooling system so tha…
The issue of increasing electricity consumption and supply needs in Indonesia is becoming more complex, particularly because this archipelagic country has many small islands far from the larger ones. This creates challenges in the distribution and provision of electricity. To address this problem, this study proposes an environmentally friendly horizontal axis wind turbine suitable for small is…
The existence of geothermal manifestations in South Sumatra is quite a lot, but has not been maximally explored. One of them is a manifestation located in Penindaian Village, Semende Darat Laut District, Muara Enim Regency. The manifestation is in the form of hot springs, hot mud, and hot steam. This hot fluid can rise and appear to the surface due to rock fractures. These fractures act as path…
