Solar driven pump used for house water system. Could also be used for pools, fish ponds, stock tanks, etc. Simple. No batteries, no controller.
The roof tank water system will work in areas where there are no hard freezes. In the subtropical and tropical states and territories of the US and elsewhere.
20151125: Update – Frankly I thought this small experimental pump would last a couple of weeks, but it is still running well after 6 months. To date I have never had to use the AC mains powered pump to compensate for a lack of sunlight. It runs on cloudy days and only stops only during the most violent parts of storms.
MATERIALS USED:
- Solar panels (2 x 40 watt, 20 volt, 2 amps)
- Switch, float
- Switch, over-pressure shut off
- 24 volt pump (2 amps, 2 liters / minute)
- Sand filter (pump input)
- Wiring, fuse
- Misc plumbing parts (1 way valve, shut off valve, …)
