Dual Axis Solar Tracking System Block Diagram

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.

Dual axis solar tracking system block diagram.

The use of a highly portable efficient solar tracker can be very useful to applications of the military industrial or residential variety. They use the same principle as the mountings of astronomical telescopes. Block diagram of the proposed dual axis system. Dual axis solar tracker can simultaneously track sun s radiation in both horizontal and vertical axis.

The siemens s7 1214 dc dc dc plc is used to control the dual axis. In order to achieve maximum efficiency the device tracks seasonal. To increase the photovoltaic panel efficiency a dual axis solar tracking system is designed and used to track the sun position. At most the solar tracker was perpendicular to the light source within 3 degrees.

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. 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. 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.

It was able to keep the solar panel aligned with the sun or any light source repetitively. 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. 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 circuit design of solar tracker is simple but setting up the system must be done carefully.

The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. To produce an efficient solar generation system a scaled down dual axis solar tracker was designed built and tested.
