Current 48 Wp 17 Adc Water output figures are on a clear sunny day with 3 times tracking of SPV panel, under Average Daily Solar Radiation condition of 7.15 KWh/sq.m on the surface of PV Array (i.e. coplanar with PV module) Standard Test Condition : AM=1.5, 2 E=W/m,Cell Temperature : 25 C # This water output is at STC conditions and testing as per MNRE s latest specifications for Solar water pumps. Rotosol solar submersible pump has a stainless steel SS-34 pump bowl and impellers which are precision laser welded. This ensures long life and high reliability against dust, sand and abrasive elements. The pump elements are driven by a sealed Brushless DC motor filled with oil/water. The motor is made from stainless steel 34 shell and sealed for life. Brushless DC motors has very high efficiency. The motor is driven by a controller which has in inbuilt MPPT (Maximum power point tracker), dry running protection and overheating protection. A special thrust bearing supports the rotor of the motor to withstand the axial thrust of the water column when the pump is switched off..
