AUTOMATIC SOLAR TRACKER

Renewable energy sources are becoming one of the most important resources in today’s world because of their many benefits. In particular, solar energy continues to be a source of non-combustible and non-polluting energy to meet our ever-growing energy needs. However, solar panels, which are important components of solar energy conversion, are not able to track the direction of sunlight through daily and seasonal changes. This reduces the area of ​​exposure to sunlight to solar panels and the efficiency of the solar tracking system involving solar panels. We have developed a solar tracking system using a combination of micro-controller, stepper motor and light dependent resistors (LDR’s) for the primary purpose of improving solar energy efficiency. A key part of this tracker is an Arduino controller designed to detect sunlight with the help of LDRs and then set up a ladder to position the solar panel in such а wаythаt it receives maximum sunlight. So this system can achieve greater light and can reduce the cost of generating electricity by requiring a small number of solar panels with the right shape and sunlight.
