Prototype of a hybrid solar panel equipped a Fresnel lens concentrator, and a solar tracking system has been developed. This hybrid solar panels isa 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 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. All measured parameters arestored in the Secure Digital (SD Card) module. Through optimization, the obtained slope angle of the solar panel is 100. Meanwhile, the optimized distance of the Fresnel lens to the solar panel is 0.2 F. The addition of Fresnel lens resulted increasing 23.83 % ofthe output power of hybrid solar panelin Rawamangun - East Jakarta area. © Published under licence by IOP Publishing Ltd.
