Solar trackers orient solar panels towards the sun using light sensors and motors. There are two main types: single-axis trackers rotate around one axis, while dual-axis trackers rotate around two axes for maximum sun exposure. Trackers increase solar panel output by approximately 40% compared to fixed panels. They work by measuring light intensity with sensors to determine the sun's position and adjusting the panel orientation accordingly through active control systems. Open loop trackers use computer algorithms and timing systems rather than sensors. Solar trackers improve efficiency and power generation from solar installations.

MAXIMUM SOLAR ABSORPTION USING DUAL AXIS SOLAR PANEL ppt
The solar tracker is used to orient various payloads toward the sun in order to trap the energy to the maximum extent. Payloads can be photovoltaic cells, reflectors, lenses or other optical devices. This tracker circuit finds the sun at dawn, follows the sun during the day, and resets for the next day. Here the payload is a Solar Photo Voltaic Panel.
Sunlight has two components, the "direct beam" that carries about 90% of the solar energy, and the "diffuse sunlight" that carries the remainder .The diffuse portion is the blue sky on a clear day. As the majority of the energy is in the direct beam, maximizing collection requires the sunlight to fall straight onto the panels as long as possible. This is where the tracker comes.

solar tracker.pptx
Solar tracker, a system that positions an object at an angle relative to the Sun. The most-common applications for solar trackers are positioning photovoltaic (PV) panels (solar panels) so that they remain perpendicular to the Sun’s rays and positioning space telescopes so that they can determine the Sun’s direction. PV solar trackers adjust the direction that a solar panel is facing according to the position of the Sun in the sky. By keeping the panel perpendicular to the Sun, more sunlight strikes the solar panel, less light is reflected, and more energy is absorbed. That energy can be converted into power.

light follower robot
This document describes the design and functioning of a light following robot. The robot uses light dependent resistors (LDRs) to sense light and an op-amp circuit to compare the light readings from the LDRs. When more light falls on one LDR, the op-amp output activates the corresponding transistor which drives the motor on that side, causing the robot to turn towards the light source. The robot aims to follow a light source such as a flashlight by moving its motors based on the LDR sensor readings processed by the op-amp circuitry. Applications include uses in street lights, alarms, and devices that adjust screen brightness based on ambient lighting.
IRJET- A Review on Design and Construction of a One-Axis Sun-Tracking System
This document describes the design and construction of a one-axis sun-tracking system for solar concentrating systems.

Industrial automation and Greenhouse effect
Industrial automation uses robotic devices to complete manufacturing tasks more efficiently than human labor. It allows for increased output and reduced costs but can also cause unemployment. The greenhouse effect is the process where gases like carbon dioxide and methane in the atmosphere absorb and re-radiate thermal radiation from the Earth, trapping heat and maintaining a warm climate for life. However, excess greenhouse gases are causing global warming that leads to rising sea levels and more extreme weather.
