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.
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.
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.
The motors are mounted directly on the rotation pins of the rotational joints to reduce losses caused by linkages and joints and to avoid using more linkages and mechanisms. The maximum expected insolation of the sun is 1000 W/m2. Assuming a 10% total efficiency of the photovoltaic panels, the predicted output power from the panel will be 100 Watt.
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.
Power generation rate might be increased by maximising the surface area of the solar panels exposed to sunlight, according to Mohamad et al. , if solar tracking devices could follow the movement of the sun. A solar tracker can drastically reduce the amount of solar panels required to produce the same amount of electricity. ... ...

This inspired the idea to adjust the angle of solar panels instead of keeping the panels immobile. The photoelectric effect occurs when photons with enough energy are absorbed by material and electrons surpass the binding energy and are released. Solar panels or photovoltaic cells use this effect to produce electricity from solar energy. Their ...
