Dual Axis Solar Tracking System Block Diagram

To produce an efficient solar generation system a scaled down dual axis solar tracker was designed built and tested.

Dual axis solar tracking system block diagram.

How the dual axis solar tracker concept works the device is able to track the daytime motion of the sun precisely and shift in the vertical axis accordingly. Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino. The block diagram below shows system architecture it consist of a ldr sensor senses max solar power which is being given to the microcontroller through the adc which digitizes the ldr output. At the end of the project a functional solar tracking system was designed and implemented.

The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. In order to achieve maximum efficiency the device tracks seasonal. It was able to keep the solar panel aligned with the sun or any light source repetitively. The siemens s7 1214 dc dc dc plc is used to control the dual axis.

The use of a highly portable efficient solar tracker can be very useful to applications of the military industrial or residential variety. On the other hand you can use the same number of. Financial impact of dual axis tracking because dual axis tracking generates 40 more power from each panel you can achieve the same power output with fewer panels frames and so on which reduces a project s upfront costs and offsets to a great extent the additional cost for tracking hardware. An ebook reader can be a software application for use on a computer such as microsoft s free reader application or a book sized computer the is used solely as a reading device such as nuvomedia s rocket ebook.

They use the same principle as the mountings of astronomical telescopes. Ebook is an electronic version of a traditional print book the can be read by using a personal computer or by using an ebook reader. This paper proposes a novel design of a dual axis solar tracking pv system which utilizes the feedback control theory along with a four quadrant. Block diagram of the proposed dual axis system.

Design of the solar tracker from this project is also a reference and a starting point for the development of more advanced systems in the future. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. The circuit design of solar tracker is simple but setting up the system must be done carefully.
