Solar Pumping System in Queensland | Grundfos SQFlex
This SQFlex Solar Pump System was installed in rural Queensland to replace a maintenance intensive submersible bore pump. The system comprises of:
- Grundfos SQFlex 2.5-2N submersible pump
- Grundfos CU200 controller
- 2 x 190W Trina Solar panels
- Reverse action pressure switch
- Pipe mount pressure tank
- Gunmetal bronze float valve
The grill covers a man dug, timber slab sided well adjacent to the main bore. The well was dug to 10 metres approx. 1910 and a windmill was connected and pumped water to the main house of 'The Park' which was part of 'Rosalie Plains' and covered some 32,000 acres in the early days.
The bore was put down 9th November 1980 and I did not have the heart to remove the concrete around the bore even though damaged. It bottoms out at 17.5 Metres and the head of water is 2.5 Metres down. Water is crystal clear and we did drink it without any taste of salt or mineral.
The overall system still amazes us considering a relatively inexpensive initial cost and a zero operating cost thereon. It took approx. 2.5 days to fill the first 32,500 litre tank, appreciating day (light) pumping only, not bad!! I am sure the installation could have been more professional but this is what happens in the bush.
