Abstract

SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.

Abstract

A sun tracker is a device that orients PV panel towards the sun, to maximize the energy efficiency of the system. Sun trackers are designed to enhance the power generation capacity of solar panels. In this chapter Arduino based sun tracker system is designed. Sun intensity is measured with the help of light dependent resistor (LDR), placed at PV panels. The system comprises of the Arduino board, three LDR and servo motor. Servo motor is connected to orient the PV panels in such a way that PV panel is always perpendicular to the sun rays to generate maximum energy.

Keywords:

Arduino, LDR, PV panel, Sun tracker system.
