Sun Tracking Solar Panel Using Arduino Circuit Diagram

Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.

Sun tracking solar panel using arduino circuit diagram. In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor. This is useful for zero pcb or breadboard circuit. We have designed a single axis solar tracking system. This article describes about circuit that rotates solar panel.

Here is a solar tracker system that tracks the sun s movement across the sky and tries to maintain the solar panel perpendicular to the sun s rays ensuring that the maximum amount of sunlight is incident on the panel throughout the day. Generally solar panels are stationary and do not follow the movement of the sun. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. Circuit diagram the circuit design of solar tracker is simple but setting.

Pcb design for arduino solar tracker. The solar panel tracker is designed to follow the sun movement so that maximum light intensity hits on the solar panel thus increasing the power efficiency. Aim of the project. This solar tracker control system is designed to take light measurements from the east and west left and right side of the solar panel and determine which way to move the panel to point it directly at.

The circuit diagram shown below. So solar panel should continuously rotate in the direction of sun. Arduino solar tracker circuit diagram. Principle of sun tracking solar panel.

The aim of this solar tracker project is to keep the solar photovoltaic panel perpendicular to the sun throughout the year in order to make it more efficient. Generally solar panels are stationary devices which is fixed at a position. The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. In the circuit two ldr light dependent resistors sensors are used to sense the light.

If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. The dual axis solar photovoltaic panel takes astronomical data as reference and the tracking system has the capability to always point the solar array toward the sun and can be installed in various regions with minor. The produced electrical energy can be increased if we move the solar panel as the movement of the sun. This solar tracker system is used for tracking the sun only in one plane the horizontal one.

In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.
