Wind-Solar Streetlight with Hydro-Powered Charging Station

This research points out an innovation on solar streetlights owing to the issues caused by prolonged period rainy seasons through the provision of engineering solutions to street lighting design assembly and in a bid to utilize renewable energy to the fullest. The developed technology consisted of three combined assemblies with the integration of various renewable sources, which included the solar panel assembly, wind turbine assembly, and hydro-electric mini-turbine assembly. The solar panel and wind turbine sets work in tandem to drive the LED street lamp efficiently, while the hydro-electric mini-turbine set is ready to regulate and supply additional power to the charging panel found at the bottom part of the streetlight. Voltage and current readings generated by said sets were tested, assessed, and measured using a digital multimeter to ensure accuracy and consistency. From the observations, the assembly of the solar panel stored a mean value of 5.39V and 1.0A caused current, while the assembly of the wind turbine produced 4.80V and 1.0A, respectively. Additionally, the hydro-electric mini-turbine had the capability of registering an average of 3.08V and 0.01A, which, while lower, also provides complementary power during rainy days. In short, the prototype device was successfully able to execute its intended function in testing and operation and demonstrate its capability to provide continuous and sustainable street lighting through a hybrid renewable energy system even under adverse weather conditions.
