Bright-Solar - Model BSLSB - Solar Water Pumping System
Bright Solar Water Pumping System of Solar Deep Well (Submersible). With A.C. Induction Motor Pump Set and a suitable Inverter.
Products Details
The PV array consists of multiple solar panels connected in series/parallel, which can supply the whole system as a power source by convening the absorbed solar radiation energy to the electrical energy. Solar pumping inverter can implement the control of the whole system operation, which drives the pump by convening DC power produced by the PV array to AC power. This inverter can adjust the output frequency according to the solar irradiation intensity in real time to implement the MPPT (maximum power point tracking).
The pump driven by a 3-phase AC motor draws water from deep-well or river. The pumped water is then fed into reservoir or water tank, or connected to the irrigation system or fountain system directly. All of centrifugal pump, axial-flow pump, mixed-flow pump, and deep-well pump can be utilized.
Solar Pumping System Optimization of Single Pump System:
A single pump system denotes that only a pump and the matched PV array and a solar pumping inverter are configured in the system. The goal of system optimization is to reduce the number of PV modules to be utilized as could as possible while meeting the requirements of water head and consumption. The pump rotational speed can be regulated according to the variation of solar irradiation: When the solar radiation intensity reaches the peak, the pump runs at its rated speed, and the output power is close to the maximum power of PV array; when the solar radiation intensity is relatively weak, the pump runs with the low speed based on the MPPT algorithm; when the pump speed is so low that no water flow can be available, the system stops working. Therefore, the solar pumping system is actually different from traditional pumping system, for which the system configuration needs to be optimized according to the requirements of water head, daily water consumption, and the local solar radiation levels.
