There are two main solar tracking systems types that depending on their movement Azimuth degrees of freedoms are single axis solar tracking system and dual. Solar Module's Performance and Solar Tracking System. 8. Solar URL: medical-site.info Accessed Abstract- “ Solar Tracking System” is a power generating method from sunlight. This method of power generation is simple and is taken from natural resource.
Since the suns position in the sky changes with the seasons and the time of day, trackers are used to align the collection system to maximize energy production. Several factors must be considered when determining the use of trackers. Some of these include: the solar technology being used, the amount of direct solar irradiation, feed-in tariffs in the region where the system is deployed, and the cost to install and maintain the trackers. Solar panels are usually set up to be in full direct sunlight at the middle of the day, facing south in the Northern Hemisphere, or facing north in the Southern Hemisphere.
Therefore morning and evening sunlight hits the panels at an acute angle and reduces the total amount of electricity which can be generated each day. A solar tracker is a device onto which solar panels are fitted which tracks the motion of the sun across the sky, thus ensuring that the maximum amount of sunlight strikes the panels throughout the day.
When compared to the price of the PV solar panels, the cost of a solar tracker is relatively low. We provide highly efficient, proprietary single and dual axis solar tracking systems.

Two DC motors 12 V are used to actuate and move the two axes in addition to control the movement of the two axes by the two angular sensors, as shown in Fig. For changing and dusting the direction of the sensor tracked the sun, an angular rotation was used besides maintaining the articulation axis horizontally.
Moreover, a pyramidal sensor is used as shown in Fig. The two light dependent resistors resistivity is measured by a digital multimeter in each angular position case . An analog control circuit intends to move to the next position when the sensor signal triggered on the frame.
Schematic of sun position sensor . As mentioned, Microprocessor and electric-optical sensors is the most widely used not only in active tracking but also in all tracker types in general.
It is also shown that this type is also widespread in Photovoltaics applications [21,37,47,56,59,62,64,—,] and few studies in applications related to parabolic concentrators [27,]. Some scholars directed their interest to study this type by implementing it on dual-axis tracking systems using two electric motors as actuators [56,59,64,,,,] while others focused on investigating one- axis tracking using microprocessor and electric-optical sensors to ac- tuate only on DC motor [21,27,37,47,].
Furthermore, some researchers studied this type of Fig. The tracking system using two opposite position sensors . LDRs are showed with their system . Bentaher et al.

Renewable and Sustainable Energy Reviews 91 — actuator operates as a heat engine during the thermal cycles. The best geographic locations to use the solar passive tracking systems near the equator due to the minimum variation in azimuth and elevation angles, high solar irradiance, and it can be useful to both high power generation and isolated applications.
Moreover, in case of bad and adverse weather conditions, the tracking system is not propped. Parmar et al. Central part of the gravity based sun tracking system, consisting of a without motors, gears, and control circuits where the gravity turns the semicircular steel pipe having a long slit, a spring, a vertical bolt and a nylon tracker, using the heat from the sun to move liquid from one side to the chord .
