Abstract Solar tracking has created a great trend in the field of producing renewable source of energy. In this paper we propose a two way solar tracking system which would increase the total efficiency, this involves tracking of the sun in dual axis. To accomplish this we have used two motors for the movement in two axis. This paper would imply that the use of the mentioned method would result in more power consumption, high operating cost.

1 Introduction The most sustainable source of energy is the solar energy. Nowadays the extraction of energy from it has become the biggest challenge, the better way extracting the energy is use of solar panels. Solar panels are the devices which harness the solar energy produced by the sun and converts the available solar energy to electrical energy. The main disadvantage of this was, it couldn’t generate the same amount of energy at different time of the day. So the concept of solar tracking came into picture, now this works on the principle of the moving the solar panel based on intensity of sunlight. We know that the sun does not exactly move from East to West, it follows [1] some direction pattern, the conventional solar tracking was about moving the solar panel vertically, this project aims in moving the solar panel in both horizontal and vertical axis so that the panel can track every movement of the sun and thereby increasing the efficiency of the solar panel.

Fig. 1 Showing the types of rays in different season
Figure 1 shows the sun’s ray when it is incident on the surface in winter and summer. From the image we can infer that during winter it has maximum slope and the sunlight energy is minimum. And due to rotation the sun’s visibility is low. During summer the sun moves inside the orbit which takes high in sky and remain there for most of the day. Due to this there is perpendicular incidence of the sunlight and has greater efficiency. As we move towards equator this effect is emphasized. In polar region the days are longer in summer and shorter in winter, while in other regions there would be slight variation in the length of day and night. Due to this reason the solar path would change depending on the latitude and they are mainly affected by the angle of incidence of the sun’s ray which plays an important role in production of solar energy. The variation is expressed as follows i.e., as the angle of incidence increases the energy production increases, therefore the main aim is to
