What Affects the Efficiency of Solar Water Pumps?
As solar energy is increasingly used, solar water pumps have gained wide popularity in the fields of agricultural irrigation, domestic water supply, industrial water use, etc., due to their advantages of being green, energy-saving, economical and practical. However, many users have reported that the efficiency of solar water pumps varies, which affects the user experience and benefits. As a professional solar water pump supplier, DIFFUL today analyzes some factors that affect the efficiency of solar water pumps.
1. Pump performance: the core of power output
Impeller design and material: Reasonable impeller design can reduce hydraulic loss and improve pump efficiency. High-quality impeller materials, such as stainless steel and corrosion-resistant materials, can extend service life and ensure long-term stable operation. If the impeller is worn or deformed, the flow rate and head will decrease, and the efficiency will be reduced by 20%-30%.
2. Controller: The "brain" of system operation
MPPT function: A controller with maximum power point tracking (MPPT) function can adjust the working voltage and current in real time, so that the solar panel always works at the maximum power point, improving the power generation efficiency by 10%-30%. Without the MPPT function, the power generation efficiency of the solar panel cannot be fully utilized, and the operation of the water pump is affected. DIFFUL independently develops high-quality and high-performance controllers to ensure that the water pump can operate efficiently.
3. Environmental factors: external conditions that cannot be ignored
1. Light intensity and duration: Light is the basis for the operation of solar water pumps. High light intensity and sufficient duration, more power generated by solar panels, long working hours and high efficiency of water pumps. In the western region with abundant light resources, solar water pumps can work up to 8-10 hours a day; while in areas with weak light, it may only work for 4-6 hours, and the efficiency is significantly different.
2. Water quality and impurities: If there are many impurities and high sand content in the water, it will wear the impeller and seals of the water pump, reduce efficiency, and may also block the pipe. The water quality needs to be treated before use, and a filter device must be installed to ensure the normal operation of the water pump.
