Usually, the output torque is set
to the maximum. If the load (solar panels’ weight) is small, the
maximum torque is not fully utilized and therefore energy is
wasted. So, a fully adjustable DC motor driver for solar
tracking system shows great potential in commercialization
because highly energy efficient DC motor driver circuit can
improves the total efficiency of the solar tracker. Fewer solar
panels are needed when they are attached to high efficiency
solar tracking system, which will be reflected to lower system
cost. Therefore, this enhanced motor driver will bring
significant impact to the solar energy industry
