Abstract
Solar energy is the most abundant renewable energy source on the Earth. It is one of the best replacement of fossil fuel which is considered as a secure, lower-risk renewable energy source. Solar energy comes from the sun and can be captured by various technologies primarily Solar Panel. Solar tracking system is mainly of two types: Single-axis solar tracking system and Dual-axis solar tracking system. Although many paper has been published on sun tracking solar panel based on microcontroller, in this paper we are trying to make a dual-axis solar panel without using microcontroller. Previously published papers have shown that dual axis solar panel is 31.4% more power efficient than stationary or single axis solar panel (Amadi and Gutierrez in Eur J Electr Comput Eng 3:1–2, 2019). Our paper is based on a dual-axis solar panel which tracks the sun using four reference panels. To make the system cheaper we are using two servomotors which will move the panel according to the sun’s position in the horizontal and vertical axis using the voltage differences of the four reference panels. The main aim is to maximize the power received from the solar panel using a dual axis solar tracking system so that the energy obtained from the solar panel can be efficiently used to run the household appliances. Use of theoretical concepts has been put into use.
