Utilization of Luminosity Sensors to Measure Potential Energy Produced by Solar Panels

Abstract In this research, the potential energy produced by solar panels has been measured through the use of luminosity sensors. A system has been created to measure the potential of solar energy and electrical energy produced from a solar panel-based power generation system. The system consists of a microcontroller, luminosity sensor, current sensor and voltage sensor which is used in a solar power generation system of 800 WP. The measurement of potential energy from the light source is then compared with the electrical energy produced within the specified measurement time interval. From the results of measuring the luminosity of sunlight, it was found that the peak luminosity ranged between 132.556-149.485 Lux which is equivalent to 1.201-1.354 W/m 2 with the highest average intensity of sunlight and solar radiation during the measurements being 140.003 Lux and 1.268 W/m 2 . From the measurement data The resulting electrical energy obtained the highest energy value of 2,2-4,0 kWh with an average of 3,1 kWh. This shows that the potential energy produced by a solar panel-based system can be obtained from luminosity measurements.
