Can solar power solve water pumping problems?
Using solar energy to partially or completely solve this issue has been an option for a long time. The first solar photovoltaic (PV) water pumping systems date back to the early 1970s (Bahadori, , Dannies, , Pytilinski, , Wenham, ).
Is solar PV water pumping system a good solution?
Similar comments although to a lesser extent, can be formulated regarding the pumping equipment, which becomes more efficient and cost effective with every passing year, thus globally making the solar PV water pumping system (SPVWPS) an interesting solution.
How to select a water pump?
However, only the peak consumption is considered when dimensioning the system. The selection criteria for the pump are the volume of water to be pumped, the working pressure of the system, the pressure drops and the efficiency of the pump-motor assembly. However, the process of selecting the pump is not explicit.
Do I need a pressure tank after Sun Down?
After sun down you would only have what’s available in the pressure tank, which some rare customers opt for because their water needs are extremely minimal. We recommend splurging on a larger capacity pressure tank rather than smaller for off grid set up, it provides some extra storage and minimizes pump cycling.
How does a submersible pump to pressure tank system work?
Two pieces of special plumbing are needed to make a submersible pump to pressure tank system work; a check valve and a reverse action pressure switch. The check valve (C), a one way valve that stops water from draining back through the pump, helps maintain pressure in the pipeline.
