This calculation shows that it is feasible to rotate the panel using electric motors fed by the output of the panel itself. The previous calculation is based on having a symmetric shape of the panel neglecting the friction of the rotational joint and the air drag force.
This leads to the maximum needed torque to rotate the panel which is equal to 15 N.m while the maximum needed power is 1 Watt which forms 1% of the output of the panel. This calculation shows that it is feasible to rotate the panel using electric motors fed by the output of the panel itself.
This orientation system is expected to save more than 40% of the total energy of the panels by keeping the panel’s face perpendicular to the sun. This percentage is assumed to be lost energy in the fixed panels. A special care should be taken to the design of the grid arrangement of panels in the collecting plant.
The total mass of the panel with the frame is 15 kg acting at a distance (d = 0.1 m) from the center of the joint as shown in Figure 4. This leads to the maximum needed torque to rotate the panel which is equal to 15 N.m while the maximum needed power is 1 Watt which forms 1% of the output of the panel.
Solar array rotation mechanism provides a hinged joint between the solar panel and satellite body, smooth rotation of the solar array into deployed position and its fixation in this position. After unlocking of solar panel (while in orbit), rotation bracket turns towards ready-to-work position under the action of driving spring.
Panels in this system rotate by 120o. Peterson et al. in Ref have designed a two-axis solar tracker with stepper motors for the azimuth and Altitude rotational degrees of freedom. Relay circuits have been used for the control purpose.
