Calculation of the electrical efficiency of a parabolic solar collector dish using TEG technology

Abstract

In this proposal study, the presentation of the thermoelectric generator, the power age by this framework is naturally companion. The objective of this task is to configure, fabricate, and test a limited-scale thermoelectric generator, as well as to explore a concentrator. Thermoelectric generator powered by solar energy, the objective of this review is to design, fabricate, and test a limited-scale sun-based concentrator. Solar Thermo Electric Generator (STEG) to add to the future improvement of STEGs as a practical sunlight-based nuclear power source in the purchaser market, is used in remote areas that are not equipped with electrical generation sources. The thermoelectric generator is built with a Peltier 12706 module, a heat sink made of aluminum, and copper with a fan, an antenna dish with a diameter of 85 cm that uses aluminum foil on a surface as a solar radiation reflector, and a programmed temperature difference monitor that includes: an LCD crystal screen 16*2, a microcontroller type pic16f676, a digital standard lm35 temperature sensor, and a small Vero Board. A solar power meter is used to calculate the intensity of solar radiation in W/m2. At 0 °C and 100 °C, all thermocouples are calibrated to within 1 °C. the result show the difference in solar radiation in different seasons greatly affects the temperature difference, which plays a key role in generating electric power through the TEC device. The value of temperatures in the summer seasons was up to 100° Celsius.
