Solar water pumping systems produced by Silicon CPV are long life and highly efficient for lifting water in the range from 10m to 200m with a daily water capacity in the range from 5m³ to 900m³. They are ideal for providing water for drinking, agricultural irrigation, forestry irrigation, desert control, animal husbandry, water supply for islands and many more applications.   Silicon CPV’s solar pumping system do not require any battery systems but can be used for direct water supply or for pumping water into storage facility. The systems are optimized for maximum water production at the lowest cost. Silicon CPV’s proprietary tracked solar arrays provide the highest pumping hours per day. High efficiency intelligent controllers deliver 98% of collected solar energy to long life high voltage high efficiency 3 phase AC motors. The motors drive submersible stainless steel pumps to lift water up to 200m. High Voltage, 3 phase AC motors improve the reliability of the pumping system and at the same time dramatically lowers the maintenance costs of the system.
By utilizing free energy from the Sun, these systems offer total independence from the fossil fuels and can be installed far away from the electricity grid making more of the barren land into productive land. This will give the farmers freedom from ever increasing cost of grid electricity or diesel and help improve the environment.

A typical solar water pumping system consists of a pump, a power-matched solar array and an inverter.  Silicon CPV’s patented solar water pumping systems aim of to produce the maximum amount of water with minimum amount of PV modules and for the longest pumping hours per day.

 The rotational speed of pump is regulated according to the level of solar irradiation; when the sunlight reaches its peak, the pump runs at the rated speed, and the output approaches the peak power of the solar array; when the sunlight is less abundant, the speed of pump goes below the rated speed until there is insufficient power to turn the motor.

 Silicon CPV’s solar pumping inverters convert DC from the proprietary solar array into 3 phase AC voltage to drive the pump. With the function of maximum power point tracking (MPPT) and maximum water point tracking (MWPT). They regulate the output frequency according to irradiation level in real time to achieve the maximum output.

  • High efficiency inverters drive pumps equipped with 3-phase AC induction motors
  • Utilizes the dynamic maximum power point tracking (MPPT) control method and maximum water pumping tracking.
  • Fully automatic operation. It can freely set speed range of pump based on the actual solar irradiation level.
  • Operation data can be logged for up to 8 years
  • Intelligent power module with conversion efficiency up to 98%
  • Full electrical protection with  water-level detection and control circuit to prevent overflow and dry extraction
  • Anodized aluminum case. Enclosure class:IP41. Ambient temperature, -10-+50.C.

The pump driven by a 3-phase AC induction motor, draws water from wells or rivers, then pours water into the reservoir or storage tank or directly to irrigation systems.In Solar pumping systems, pump selection is very important, this will directly affects the economy and stability of the whole system. Correctly selected pump type can increase working time and water flow rate of the solar pumping system. For example, low head and high water flow will require a different pump configuration compared to high head and low water flow.
Precautions :
Do not run the pump dry  – Solids in the water should not exceed 0.02% (weight ratio) – ph level of water must be in 6.5 -8.5 range.
