The increasing energy dependence limited source
of the fossil fuels, their increasing price and negative environmental impacts
force mankind to improve the utilization of the available renewable energy
sources. Renewable sources represent an inexhaustible potential of energy for
the future. Among renewable sources solar energy is one of the most promising
now days. The sun’s position tracker mechanism is to be composed of the PLC, DC
Motor, worm gear, photo sensor, encoder, power relay and inclinometer. The
program to tilt the panel according to sun’s position is to be feed on PLC. An
inclinometer fixed behind the panel measure the angle of panel and it gives
feedback to PLC.An overview of the solar cell technologies and their efficiency
of this conversion depends on solar radiation that reaches the surface of the
solar cell. Another option is to track the sun’s path in daylight hours. Some
researchers have conducted various studies to establish the optimal degree of
tilt solar panel to increase the output power. Because the position of the sun
changes during the courses of the day the implementation of the solar tracker
is the best solution to increase the energy production. The performance of a
solar collector is highly influenced by its orientation (regarding the Equator)
and its tilt angle (regarding the ground).this can be achieved by proper
design, construction, installation and orientation. In PV cell shadows are
known to damage the solar cell due to the creation of the hot spot to the
panel. From the reference study it can be seen that optimization of tilt angle
of the solar panel can be done by using Soft-Computing technique. Depending on
number of axis the panel can be move and tracking can be differentiated.
Knowledge of these angles would further allow us to track the sun on a monthly
basis rather than daily hour based tracking. The process can be seen from the
Fig 1.
