The SOLAR PANEL POWER CONTROLLER - STANDARD VOLTAGE UNIT (SPPCS) multiplies the solar panel’s starting current for motors.
Normally, powering an electric motor directly from a solar panel can be quite inefficient, especially during start up and at low motor speeds.
The SPPCS allows the motor to start and operate at a much lower light intensity than is possible with the motor directly connected to the solar panel.
This SPPCS circuit holds the output of the solar panel at its maximum power voltage point. Thus it is able to substantially boost the starting current available to the motor.
NOTE: This circuit regulates the input voltage rather than the output voltage.
Energy consumption by the circuits is 0.04 W (approximately). The SPPCS’s weight is approximately 45 grams (including the inductor).
The SPPCL will work with any solar panel or combination of solar panels whose Voltage Open Circuit (VOC) voltage is between 13 and 23 volts.
NOTE: A rated 12V panel at VOC will be higher than 12V
