Smart fabrication of dual axis solar tracker

الملخص EN

Currently, the most renewable energy production is produced depending on wind and solar energy are widely used in developed countries and some developing countries; Lately, the means of producing electricity using renewable energy sources have become commonplace, and there are many countries that have put in place plans to increase the percentage of their production of renewable energy so that they cover their energy needs by 20% of their consumption in 2020.

Photovoltaic panels are used to convert solar energy into electrical energy.

When photovoltaic panels are fixed at a particular angle, limited power can be generated.

This disadvantage can be decreased by designing a solar tracker system which changes its position automatically in accordance with the sun's movement.

Dual axis solar trackercan continuously track the position of the sun in vertical and horizontal directions.

This paper aims to implement the most accurate control application of dual-axis solar tracker which can rotate in horizontal and vertical directionthat grantee the photovoltaic panel remains perpendicular always facing the sun.

The fabricated tracker achieves higher efficiency so the solar panel remains a sun-oriented position at all times using two linear DC motors, an Arduino UNO controller and some auxiliary components to improve the energy generated from PV panels up to 36% .
