Hardi Transfer Pumps
This is a basic guide for the most popular size of solar systems we build using 200 watt panels. Many other options are also available, eg. small systems using an 80 watt panel and much bigger systems using up to 470 watt panels of various voltages.
The table shows litres per day over a 6 hour period.

- Hardi Pump with Angled Solar Panels
The angling of panels provides numerous opportunities.
It provides a longer run time by facing the panels to the NE for an early start of the day and the other side to the NW to catch the late afternoon sun. This is ideal for a larger volume of water per day or when the water supply is limited providing a longer and slower pump of water.
Another advantage is the way the pump performs on very cloudy days. This is due to the large surface area collecting power from all directions due to the diffused sunlight energy.
This layout of angled panels works extremely well when a battery system is incorporated with a solar pumping system.
With panels facing the sun the NW right up until the last minute of the day, the batteries are topped up and ready for the night operation. The batteries do not cycle so deeply as they would with panels on the North plain.
