Question : Why Suguna solar pump use frequency converter
Answer : variable frequency motor will actively change their speed according the all time changing power which provided by solar panels, Perfect combination with MPPT, ultra-frequency operation, make sure absorb above 95% power provided by panels. Improve customer return on investment. The traditional AC motor only get maximum speed is 2850RPM, and it only could passively discarge according the voltage, not according power. Efficiency will low.

Question: Why suguna solar pump use shield motor
Answer: Shield design make the mechanical seal is unnecessary, avoiding the risk of mechanical seal leakage because of mechanical seal wear and tear. Avoiding the reduce of efficiency because of mechanical seal friction also, at the same time, wet rotor cooling better.

Question : Why suguna solar pump use BLDC motor not brush DC motor
Answer: Although brushed DC motor can work directly with solar panels also, its not good option, there have follow different form BLDC.
Life BLDC motor is 10000H, while brush pump Maximum life is 2000h-3000h because the brush and slip wear and tear.
DC brush pump system have very low efficeincy without MPPT, without any protection because of without controller also, noise, safety are significantly higher than a BLDC motor.

Solar Panels Require
The solar module is equipped with plugs and sockets for easy connection of several modules in series connection. The solar panels are mounted on a support structure, tilted at an angle ensuring optimum utilization of the solar energy. The number of solar modules is determined by means of the pump type. ( The pump type and solar array power shown in table below).
