How the System Works

The DC screw solar water pump works with solar panels through a dedicated controller. The controller regulates input power and helps maintain stable pump operation under changing sunlight conditions.

Solar panel supplies DC power to the system
Controller manages startup, protection, and pump operation
Pump lifts water from deep wells or boreholes
Water level control can be added when required
System can be designed according to local project conditions

How to Select the Right Model

Screw solar pumps are commonly selected for projects where well depth is greater and stable head performance is more important than very large flow. Before choosing a model, customers should confirm water level depth, required daily water volume, tank height, and actual sunshine conditions.

Correct model selection helps the system run more efficiently and ensures the solar panel and controller are properly matched with pump voltage and power.

Confirm well depth and dynamic water level
Check required flow and vertical lifting distance
Match solar panel voltage and power carefully
Choose screw pump models for deep well high-head demand
