How do you design a solar water pumping system?

When designing a solar pumping system, the designer must match the individual components together. A solar water pumping system consists of three major components: the solar array, pump controller and electric water pump (motor and pump) as shown in Figure 1.

Can a solar water pump be powered by an inverter?

An inverter converts DC output from solar panels into AC. Thus, with the correct inverter, most AC pumps can be powered by a solar array. Inverters are typically used in a solar powered water system when the pump capacity needed exceeds the capacity of the pump and motor combinations (or PV pump aggregates) that can take DC input.

Where should a solar tank be installed?

The solar tank should be installed near the center of your water supply piping system or where water is most commonly used. This ensures that hot water is readily available. The tank must be installed indoors and must stand in the vertical position on a level surface.

How to choose a solar water pumping system?

The type of solar water pumping system: borehole/well (submerged), floating or surface will depend on the water source. If the source is a borehole (proposed or existing) or deep well, then a submersible pump that fits the borehole or well should be selected. If the water source is a river, then a surface pump should usually be selected.

How do I install a T/P valve on a Duda solar tank?

The T/P valve should be installed into the T/P port or top of the Duda Solar Tank. Connect piping to the outlet of the T/P valve to direct ejected fluid to the drain pan or directly to the sewer.

How do you drain a solar tank?

To drain a solar tank, first, turn off the water from the main supply going to the tank. Next, open the drain valve located at the bottom of the solar tank*.* Open the temperature/pressure relief valve at the top of the solar tank to allow air into the tank and help the water drain. Remember to close the release valve after refilling the tank.
