Description:

Solar energy is one of the most reliable alternative energy sources in this modern era. Photovoltaic panels are used to collect solar energy and convert it into electrical energy. But these photovoltaic panels are inefficient as they are fixed only at a particular angle. But we can easily overcome this problem by using a sun-tracking solar panel system.

A solar tracker is a device that orients solar panels towards the sun. Based on the axis of rotation there are two types of solar trackers - (1) Single axis solar tracker (2) Dual-axis solar tracker

This project has been performed for enhancing the efficiency of the conventional PV energy production system by keeping the solar PV panel perpendicular to the sun throughout the year. Based on the incident light reading of a light-sensing sensor, one horizontal and one vertical motor will be made to move so that the panel is brought to a position where it receives the highest irradiance.

Description :

In this project, a helical coil heat exchanger has been designed which is an extension of the double pipe heat exchanger. As the helical coil creates an increased path for fluid flow, the total heat transfer surface has been enhanced. For this reason, a significant amount of heat transfer improvement has been observed.
