8 Elektro UK Petra Jurusan Teknik Angle of Reflectors

9 Elektro UK Petra Jurusan Teknik Angle of the sun-shine March 21 & June 21

10 Elektro UK Petra Jurusan Teknik Setting the Angle of Reflectors Microcontroller ATMega8 is used to generate output signal to trigger the motor driver that moves the motors of the reflectors to position itself in its correct angle. There are two option of operation being used in this plant. Open loop system, where the angles of the reflectors are calculated based on the input of the date and location of the plant. Closed loop system, where the reflectors are moving, looking for the best angle by itself.

20 Elektro UK Petra Jurusan Teknik Conclusion Double reflectors using common mirror as explained in this article has proved that it is able to increase the output of solar cell. This method is relatively cheap and suitable for a country such Indonesia where there is no solar cell factory in the country. Yet the output of a solar cell can be increased by using mirrors.

21 Elektro UK Petra Jurusan Teknik Conclusion The measurement has neglected the effect of un-equal intensity of radiation on the surface of the solar cell. Because the solar cell is placed fixed horizontally, therefore during the morning and late afternoon the reflected sun-shine won’t fall at the whole surface of the solar cell completely. This phenomena is logically true when we saw the result of measurement. By using this system which can be produced locally, one can increase the output of solar cell up to 23,93%.
