How does a solar pumping system work?
Solar panels convert sunlight to electricity. The electric current passes through a control box which manages the power flow to the pump. The current is then used to drive the pump’s motor.

How much water can a solar pumping system pump?
This depends on the head (lift). the size / type of pump being used and the number of hours of sunshine per day. We have systems which will deliver up to 25, 000 litres per hour at low heads and others which will pump to heads of more than 100m. Talk to us about the best system for your needs.

What exactly is “head”?
This is the pressure the pump is working against, normally expressed in metres. It consists of two parts:
Static Head – The vertical distance the water is being lifted.
Friction head the backpressure caused when a liquid flows through a pipe. This is affected by the pipe diameter, the type of pipe, the length of pipe and the rate of flow.

How much do your systems cost?
Prices depend on the size of the system, the type of pump and any extras needed. Talk to us regarding your requirements and we can provide a detailed quote.
5
Do I need any specialized skills to install one of your systems?
Our kits are designed so that the average DIYer can install them. Electrical connections are either plug together or pre wired. Other sections are bolt together. Simple step by step instructions are provided and we are only a telephone call away.
6
Do your kits switch on / off automatically?
No, there is a manual switch on the control box. There are several types of automatic control available as options, including float switches, pressure switches and wireless remote systems. Talk to us about the correct one for your application.

What maintenance is required on your solar pumping systems?
All solar pumps should be checked regularly to ensure they are functioning nproperly. Check that the mounting frame for the solar panels is secure and if the panels themselves are dirty they should be washed with a mild detergent solution.
8
Do your panels track the Sun?
The panels do not track the sun although the angle can be adjusted seasonally. Trackers can increase efficiency but this is primarily in Winter where less water is needed.

What is MPPT?
MPPT is short for Maximum Power Point Tracking. The control system for the pump adjusts the speed of the pump so that it operates at maximum efficiency for the power being produced by the panels.
