Why do we use solar tracking system?
Solar trackers are devices used to orient photovoltaic panels, reflectors, lenses or other optical devices toward the sun. 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.
How much difference does a solar tracker make?
Generally, a solar tracker will make a solar panel around 40 percent more efficient. Depending on your goals, that means you can use 40 percent fewer panels to generate the same amount of electricity, or you can use the same number of panels to generate 40 percent more.
How does a single axis solar tracking system work?
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. The rotation axis can be horizontal, vertical, or oblique.
Which is a disadvantage of single axis tracking?
Single-axis tracking has the advantage of simple structure; the disadvantage is that the incident light cannot always be perpendicular to the collector’s aperture, so the collection of solar energy is not enough to maintain the maximum.
How are solar trackers used in solar cells?
Solar tracking system is the most appropriate technology to enhance the efficiency of the solar cells by tracking the sun. A microcontroller based design methodology of an automatic solar tracker is presented in this paper. Light dependent resistors are used as the sensors of the solar tracker.
How is a single axis tracking collector made?
The PTC is a kind of single-axis automatic tracking collector with a high concentration ratio, usually around 40–80 times the sun. PTCs are made by bending a sheet glass mirror or reflective aluminum into a parabolic shape. PTCs can produce heat at high temperatures, between 150°C and 400°C.
