This paper provided a thorough comparative analysis between the light-dependent resistor (LDR)-based light system and the commercialized automatic solar-powered light system. It aimed to developed a better system of streetlights in the location of the study. The proposed work was carried out by creating a prototype of an automatic streetlight using a light-dependent resistor (LDR) and purchasing an automatic solar-powered light system from online retailers. An LDR sensor was used as a switch in the automated LDR-based street lighting system. The researcher's goal was to compare and analyze which streetlight system was more beneficial for the community of the location site. This project provided the most effective solution to the streetlight issues as well as the cost and durability of a better streetlight system. Additionally, the study analyzed both streetlights to determine which will be more beneficial in terms of total investment cost (by getting the total unit of Pesos), output efficiency (by getting the Lumens per watt), and durability (by using a table of literature review). This comparative analysis between the two streetlight systems was done at the study location. After the study, the final conclusion obtained was that the LDR-based light system was better in terms of output efficiency and durability. While the commercialized solar-powered light system was better based on the total investment cost that the researchers computed. The study concluded that the LDR-based streetlight system was chosen as the preferred alternative as an automatic streetlight system for the community of the location site because of its output efficiency savings and durability. The LDR-based streetlight system also proved to be an environmentally friendly, highly efficient, and durable type of streetlight system. Additionally, this study did not bothered residents since they were notified about the study being conducted. In addition to this, researchers also concluded that all of the hypotheses are valid.

This paper explores the efficiency of solar panels during a solar-powered payload flight as it reaches stratospheric altitudes and is subjected to different environments, as well as the possibility of utilizing solar-powered payloads for future weather balloon flights, replacing conventional batteries as energy sources. The payload was equipped with temperature, pressure, and GPS sensors to measure and analyze the environments the payload experienced, while also including INA219 sensors to measure the voltage/current generated by the 6V solar panel array designed and provided to a Teensy 3.5 microcontroller testing unit throughout the flight. The Teensy testing unit was additionally equipped with a backup Li-on battery to be used during periods when the solar panels were under the shade of the balloon. Results from the flight determined that the solar panel array experienced a 19 percent increase in power production compared to ground testing when it reached the coldest point in the tropopause. Furthermore, even during extended periods of shade, the array was capable of providing adequate energy to the Teensy testing unit without tapping the backup battery, and continued throughout the entire flight. It is theorized that an increase in solar irradiance at greater altitudes might have also caused this unexpectedly large supply of solar energy. Therefore, further testing with luminosity and spectral irradiance sensors in future flights is recommended. [ABSTRACT FROM AUTHOR]
