I highly recommend a Lorentz SOLAR pool pump, (German design) which runs from early morning to the evening without costing you any electricity.
Green Air installed hundreds of them from 2009 on and most of them are still doing their job after 12 years, without needing any repairs.
All you need is space for 3 solar panels (modules), size ca 2 by 1 meter. You will roughly save 1000 Euro/year electricity costs when running a normal 1hp pump 8-10 h per day. After some years you have your invested money back. No permits from EAC necessary.

Thanks do these heat the pool to.
Solar pool pumps are circulation pumps, which run instead of AC electricity from the grid, with the DC electricity provided by 3 solar modules.
However they can be connected also with various pool heating devices (thermal panels, heat pump, electric coil etc) This way they save also enormous amount of electricity to circulate the heated water with zero electricity instead running a electric pump.
We had our Lorenz Pump fitted in February last year. When Green Air did our extensive pool work, they arranged the equipment in our new pump room, (a Keta Shed) so that there was room for a solar pump at a later date. It is brilliant and we use it to circulate the heated water from our Fairland Air Pump pool heater. In the winter, it comes on at first sunlight and on a sunny day turns off around 4:15pm, as the panels are east facing, so the water is circulating for 9 hours. per day. Also, with the pool sanitiser, we hardly use any chemicals. It runs for all daylight hours. Yesterday it was sunny and it came on at 7:15am and ran till 4:15pm. Today, a cloudy start to the day and it came on at 8:15am and ran till around 3:45pm, so even on a cloudy day in winter, it is still running and circulating the water.
Have a word with Green Air. One of the technicians told me that he could keep our swimming pool pump running forever. Maybe a repair to your existing pump and fitting a Lorenz Solar Pump might be the solution.
We've had a Lorenz Pump for around 10 years (Max can say when it was fitted) and all in all apart from a broken impeller which was replaced that's been the only problem.
Saves us a fortune but its making a few noises now so will have to get Greenair to sort it out or replace it..

What is the pumping capacity in terms of litres per hour of the pump you quote above please.
Pumping max. capacity of the solar pump is 18 tons/hour. So a normal pool size is 40-50 tons of water which will be through the filter several times a day....
I agree with above re Solar Pump, had one for around 6 years.
Inverter failed but was replaced, otherwise an excellent investment.
Less chemicals used, less cleaning of pool required, and of course free to run .....
Just asking, but if you are having a PV system installed, you will be generating free electricity to run a standard pool pump. I run my standard pump during the day at zero cost. I do not understand why members are suggesting you need to double up?

My opinion is that every chance to get the sun involved producing electricity counts. As the prices for PV went down the last years it would make sense to install a solar pool pump system as well as your investment is paid back in led say 3 years app. Normal pool pumps are next to air-cons the largest consumer in a Cypriot household and you could use the electricity you produce with your PV-system for other things, p.e. a future e-car or electric heat pump instead of gas/diesel central heating. By the way, solar pool pumps are very efficient as they are DC pumps which have no losses as DC comes also from the solar modules and need no conversion. I don't think that in autumn and spring when we have cloudy conditions you will run to your pool house and switch off the power of the pool pump not to waste electricity. At the same conditions the solar pool pump will still do its job without attention....costing no electricity at all.
I tend to agree with TD…….if one is having or already has PV panels installed to supply the whole house for ‘free’ electricity then why would one want to spend an extra ca €3-4k ( my figures) installing another 3 panels and DC pump purely to run the pool?
I’m assuming of course that the Lorentz DC pump requires its own dedicated PV panels and cannot be run off existing PV panels.
If that is not the case then please would someone let me know.
On the other hand, a Consumer of many, many KW of electricity may well find 2 separate systems beneficial/cost effective.
I can't remember how much ours cost to be honest. But you are better off just asking for a quote. It was a couple of years ago now, and prices do change.
And we have regular PV panels too, but they don't generate enough electricity to cover all our usage, so that isn't an issue. Plus, we have it running all the time*, which is why the pool is easier to maintain.
* Well, in daylight, anyway.

Green Air installed your Lorentz solar pool pump system late spring 2011. So it is going to be 11 years old in a few month.... Nowadays the solar modules installed producing much more electricity (>250 Wp each) while in 2011 they were only 190 Wp, which means even if it rains the pump will circulate the poolwater. By the way: your neighbours up the road got their pool pump in the same year with a 10x5m pool!

Max roughly how many units a year do the Lorentz pumps use, i know its off grid but can they be used through a PV System as i dont want any ugly panels on view.
No, they can only run with 3 or even 2 solar panels (modules). If you don't like the blue colour they are also available in black which look quite nice (for me)
I had customers in the past at Kamares and their modules were even more than 80 m away from their pool house as they did not want to see them, like you. So, no problem ...
