Ppt On Solar Panel Tracking System Mechanism

So solar panel should continuously rotate in the direction of sun.

Ppt on solar panel tracking system mechanism. Since the sun s 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. Pv solar systems exist in many different configurations with regard to their relationship to inverter systems ext. A single axis solar tracking system uses a tilted pv panel mount and one electric motor to move the panel on an approximate trajectory relative to the sun s position. This solar tracking system is cont rolled by a micro chip pic 18f452 micro controller.

Maximum power point tracking mppt or sometimes just power point tracking ppt is a technique used commonly with wind turbines and photovoltaic solar systems to maximize power extraction under all conditions. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun. Conclusion the invention of solar tracking system helps us improve the performance of pv solar system in a simple way used relative method of sunlight strength. These provide the signal to motor driver ic2 to move the solar panel in the sun s direction.

1 shows the circuit of the solar tracking system. The aim of automatic solar tracker is to design the system which will automatically track the sun s position and accordingly change the direction of the solar panel to get the maximum output from the solar cell. Because solar tracking implies moving parts and control systems that tend to be expensive single axis tracking systems seem to be the best solution for small pv power plants. The search mechanism p ilot locates t he position of the sun and the.

Improved the utilization rate of solar energy and efficiency of photovoltaic. For example optical power transmission and thermophotovoltaics. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Although it primarily applies to solar power the principle applies generally to sources with variable power.

These light sensors also compare the darkness and cloudy and sunny conditions assisting daily tracking. The rotation axis can be horizontal vertical or oblique. Established a model of automatic tracking system to keep vertical contact between solar panels and sunlight. Solar trackers are devices used to orient photovoltaic panels reflectors lenses or other optical devices toward the sun.
