A slightly different topic are our solar water pumps. The pumps run directly connected to a solar panel, once the sun starts shining.
All of our pumps -regardless of their waterhead- do up to 45l/min. Surely you can implement your own free water fall with it, but we suggest to collect rain water in an underground cistern or tap a deep well and pump it in a tank on the roof of your house. If you optimize things you can say good-bye to the next bill, but this time it is the water-bill!
The 24 Volt pumps can be used directly without controller and battery, just connect them, wait for the sun and the water will rise! The pumps have 76mm diameter (intake) and a 32mm thread for connecting a hose and run at 12 Volts or 24 Volts depending on the model. The casing is all stainless and they have 2 meter cable attached. It is rated IP68 and as such fully submersible, running at 18,000 RPM and have an average lifetime of 20,000 hrs. The pump is visible on the first photo above, it’s small against the panel.

We don’t and we will not have larger than 20 m water head available. Stocks are limited, we have only a few units left.
The 12 Volt pumps have a Voltage range of 12-18 Volts. Note that most panels have up to 20 Volts, thus you need to use a controller and battery.
The 24 Volt pumps have a Voltage range of 22-45 Volts thus allowing direct solar applications with or without controller.
We strongly recommend to use the pumps only with our recommended panels, do never attach more than the recommended wattage.
Please note that these are a new revised 2013 version of our previous pumps. They have an integrated MPPT controller, which makes them a lot more powerful than the previous versions. They now can now even exceed their stated waterhead.
Further they have an overvoltage and overcurrent-protection and the bigger pumps 20 meter+ have brass couplings instead of plastic.
We were able to verify with the supplier and a customer that these can be also used with salt water applications.
We offer one week warranty for the pump, so you have enough time to test functionality. For further service or parts you will need to contact the manufacturer in China, as we are not a regular importer or repair service of these pumps.
We tried several of the pumps here and are quite impressed, how much water you can pump with a single panel! This however during full sunshine, once there are clouds performance decreases.
For maximum waterhead it’s best to run them on a panel (full sun at 90 degree) and controller with battery, so the battery remains at perfect charge condition. Don’t run your planning too tight (using a 10m pump for 10m elevation) as you won’t be able to use it on days where the sky is not perfect – add allowance.
The water pumps can be shipped via LBC nationwide, insured shipping for the small 10meter pumps starts at P450.
We also have electric float switches for 12/24V (max 10 Amp!) at Php 900 that can turn on/off the pump automatically. Since they can do only 10 Amps these are only recommended for our 10 meter water head pumps (possibly for the 24Volt/20meter model, too)
