Tips: How does the water well pump keep supplying water?
The solar water pump exclusively uses the DC power of the solar panel. It must operate at lower power in low light conditions and is guaranteed not to stop work or overheat. The water passes through the sealed cavity of the pump and is pressed upwards. Even if the pumping is slow, it can maintain the lifting capacity. The pump consists of a diaphragm, vanes and a piston. It differs from conventional centrifugal pumps that require fast rotation for efficient operation (centrifugal pumps require a higher volume). Most deep wells choose solar submersible pumps.
The pump controller (solar pump inverter) is an electronic device used with solar pumps. It can be divided into the external type and internal type. Like an automatic transmission, it helps the pump start-up and does not stop in low sunlight.
As the sun moves through the sky, solar trackers can be used to tilt solar panels. This adds at least up to 55% of daily energy. On a clear sunny day, the tracking effect is the best. It is less effective in cloudy weather and winter.
Storage is very important. Depending on the climate and water usage, store 3 to 10 days of water as needed.
When the tank is full, the float switch can turn off the pump to prevent water spillage. Most systems use water storage instead of power supply storage, which makes the system more streamlined and economical.
Compared to windmills, solar water pumps are cheaper and easier to install and maintain. They provide a more consistent water supply. They can be installed in storm-deficient valleys and wooded areas. The solar panels can be far from the pump itself, even a few hundred feet (100 meters) away.
