Abstract
This project is to study of solar aerator system by purpose to design a solar power system for aerators using only one solar power source. The project scope had been measuring the water hitting performance of two impeller difference forms which direction can get the direct solar energy. It has been working at 09.00 am - 05.00 pm. by designing the solar pane structure in automation system that is able to move in the sun direction in the morning and in the afternoon by automatic panel system, and this experiment will be conducted at Amata Nakorn Industrial Estate.
By design, it has been implemented with using a common market solar panel on the size of 330 watts which the panes is tilted at an angle of 15 degrees on maximum exposure to the sun comparing to the horizontal and vertical direction and turned the mechanical to the south and used the PLC system to control the entire solar aerator system. The observation was found in the practical application that the weight of structure is submerged too much which will be caused a short circuit breaker to safe the electrical circuit system.
The best result of the solar panel efficiency trials is to place the panel at 15-20 degrees in the south, it was found that the 8-blade propeller can generate oxygen in the water better than the 6-blade propeller which can hit the water as far as 80 centimeters at a motor speed of 2300 rpm, an average current of 1.526 amps. In addition, the 8-blade propeller can hit the water as far as 100 centimeters at 2300 rpm motor with an average current of 1.522 amps. The both propellers use electricity similarly, but the 8-blade propeller can hit the water farther, resulting in better water flow than the 6-blade propeller.
