Abstract
Prototype of a hybrid solar panel with a Fresnel lens concentrator and a solar tracking system has been developed in this research. This hybrid solar panels are a combination of conventional solar cells and thermoelectric generators. Solar cells work to convert solar radiation, whereas thermoelectric generator converts solar heat into electrical energy. A Fresnel lens, a refractive lens type, is used as a solar concentrator, whereas the solar drive system uses solar azimuth data. This prototype is equipped by INA219 sensor as a measure of electric current and the output voltage of solar panels. The temperature gauge uses a DS18B20 sensor, and the GY 49 MAX44009 light sensor is a light intensity detector. Solar panel drive uses MG995 servo motor and RTC module. Measured parameters are stored in the Secure Digital (SD Card) module. Through optimization, the obtained tilt angle of the solar panel is 10 degree. Meanwhile, the optimized distance of the Fresnel lens to the solar panel is 0.2 F. The addition of Fresnel lens resulted increasing of the output power of hybrid solar panel, there is 9.1 percent in the Sawah Lama-Tangerang Selatan area, and 23.83 percent in the Rawamangun - East Jakarta area.
