Dual Axis Solar Power Tracker System
Project Area of Specialization Electrical/Electronic EngineeringProject Summary- There are many ways to produce electricity. Among of them solar energy is becoming one of the most expanding renewable energy it is getting more prominence day by day. So solar energy is a clean method for the generation of electricity in form of renewable enregy. While production of electricity from solar panels there exist a issue that when sun moves so solar panel remain at its position and further panels not charged. So this technology will rotate the solar panel when sun changes its direction.
- Sun trackers can substantially improve the electricity production of a photovoltaic (PV) system. So dual-axis solar tracking PV system that utilizes the feedback control theory along with a four-quadrant light-dependent resistor (LDR) sensor and simple electronic circuits to provide robust system performance. This project will include the design and construction of a microcontroller-based solar panel tracking system. In hardware development we utilize LDR’s as sensors and two servo motors to direct the position of the solar panel. Dual-axis solar tracking allows more energy to be produced because the solar array is able to remain aligned perpendicular to the sun.
- The main objective of this project is to achieve maximum power without any loss.
- Stationary panel can’t achieve maximum power, due to this reason we will design a device that will rotate with respect to sun
The daylight force from four unique headings is estimated by the LDR-based detecting circuit. The voltages VTL, VTR, VBL, and VBR are defined as the sensing voltages produced by the top left, top right, bottom left and bottom right LDRs respectively. While trying to draw most extreme power from the PV board, the azimuth and rise following cycles can at the same time continue until the PV board is adjusted symmetrically to the daylight. The tracker establishment isn't confined to the topographical area. Calculation for Motor Control The calculation gives a portrayal of the overall advances attempted for the venture: 1. There is a contribution of voltage from the two sets of LDRs. 2. The information sources are simple. They are changed over to advanced qualities. 3. The two advanced qualities are analyzed and the distinctions between them are acquired. 4. The contrast between the qualities got is the mistake relative plot for the turn of the servo engine. 5. Assuming the LDR voltages are something similar, the servo engines stop. In any case, the servo engine pivots until the distinction turns into something very similar.
Benefits of the Project- Sunlight based trackers are gadgets used to situate photovoltaic boards, reflectors, focal points or other optical gadgets toward the sun. Since the sun's situation overhead changes with the seasons and the hour of day, trackers are utilized to adjust the assortment framework to augment energy creation.
- A few variables should be viewed as while deciding the utilization of trackers. A portion of these include: the sunlight based innovation being utilized, how much direct sun oriented light, feed-in levies in the area where the framework is conveyed, and the expense to introduce and keep up with the trackers.
- Concentrated applications like concentrated photovoltaic boards (CPV) or concentrated sun oriented power (CSP) require a serious level of exactness to guarantee the daylight is coordinated unequivocally at the point of convergence of the reflector or focal point. Non-concentrating applications don't need following however utilizing a tracker can further develop the absolute power delivered by the framework. Photovoltaic frameworks utilizing high proficiency boards with trackers can be extremely successful.
The sunlight power from four uncommon headings is assessed by the LDR-based seeing circuit. The voltages VTL, VTR, VBL, and VBR are depicted as the recognizing voltages made by the upper left, upper right, base left and base right LDRs freely. While attempting to draw most ridiculous power from the PV load up, the azimuth and rise following cycles can simultaneously go on until the PV load up is changed impartially to the light. The tracker foundation isn't bound to the land region. Estimation for Motor Control The appraisal gives a depiction of the general advances pursued for the endeavor:
- There is an obligation of voltage from the two plans of LDRs.
- The data sources are immediate. They are changed over to best in class ascribes.
- The two progressed ascribes are investigated and the capacities between them are gotten.
- The detachment between the characteristics got is the misconception relative plot for the turn of the servo motor.
- Accepting the LDR voltages are something basically undefined, the servo motors stop. Regardless, the servo motor changes until the capacity changes into something basically the same.
