Reducing Costs

The renewable energies, solar energy is the only energy gained its popularity and importance quickly. Through the solar tracking system, we can produce an abundant amount of energy which makes the solar panel’s workability much more efficient. Perpendicular proportionality of the solar panel with the sun rays is the reason lying behind its efficiency. Pecuniary, its installation charge is high provided cheaper options are also available. The main control circuit is based upon NodeMcu microcontroller. Programming of this device is done in the manner that the LDR sensor, in accordance with the detection of the sun rays, will provide direction to the DC Motor that in which way the solar panel is going to revolve. Through this, the solar panel is positioned in such a manner that the maximum amount of sun rays could be received. Though a hike in the efficiency of the solar panel had a handsome increase still perfection was a far-fetched goal for it. Below 40%, most of the panels still hover to operate. Consequently, peoples are compelled to purchase a number of panels in order to meet their energy demands or purchase single systems with large outputs. Availability of the solar cells types with higher efficiencies is on provided they are too costly to purchase. Ways to be accessed for increasing solar panel efficiencies are a plethora in number still one of the ways to be availed for accomplishing the said purpose while reducing costs, is tracking. Tracking helps in the wider projection of the panel to the Sun with increased power output. It could be dual or single axis tracker

In order to improve the solar energy utilization, in the respect of technology, we should perfect solar tracking devices, realization of the sunlight is always vertical to the solar panels. This paper is to design a kind of solar automatic tracking system. Design adopts the traditional photoelectric tracking method, with the FPGA as the core, and by using the methods of scheduled monitoring, achieve precise control of stepping motor, thereby promoting the solar panels rotate remains vertical to the sun, which can effectively improve the efficiency of solar power systems.

Laser cutting focus position automatic tracking system of control precision directly affects the quality of laser cutting processing. There is a low anti-jamming capability, poor quality,poorer openness and poorer dynamic response short comings in the inductive sensor or the capacitive sensor and constitute of the single chip microcomputer control system. This paper introduces a laser focus automatic tracking system based on motion controller, using optical encoder as displacement sensor, use the motion controller of master-slave tracking (electronic gear) function implementation focus position error compensation quickly. Improve the quality of system control, openness, the stability and reliability.

The acquisition, alignment, and tracking system is an important part of airborne laser communication and is the prerequisite and guarantee for the normal communication link. In order to solve the problem of automatic tracking of laser communication links in the airborne environment, the rapid capture, alignment, and tracking of beams between terminals are realized. This article proposes a stepping motor as a control servo system and a four-quadrant detector as an automatic tracking method for the detection unit. The pulse width modulation signal controls the rotation speed of the stepping motor and combines the position distribution of the light spot on the four-quadrant detector to achieve high-precision beam tracking. On this basis, indoor simulation experiments are carried out. After many experiments, the tracking accuracy is better than 2.5 μrad, which shows that the system can be applied to airborne laser communication, and it is verified that this method has good automatic tracking performance for airborne laser communication.
