Andrew you should have all the info now.

Good luck - hope you get a "yes" vote later, or you might never be able to get it done.

Photos and helpful advice received. Thank you so much. I will get on the case today. There is at least one specialist PV contractor on the island where I live.

PW in Polemi has asked me to reply with the technicals.

In 2011 we installed Lorentz DC pool pumps at our home and the holiday cottage. The DC pumps run in tandem with the normal pump and then the normal pump acts as a standby. The pool pumps require 3 x 235W panels and run automatically every daylight hour, even in the rain. You don't need much space for these, just uninterrupted sunlight all day facing south. A picture of our holiday cottage panels is on our website www.cyprus-holidaycottage.com. The cost in Cyprus to install a Lorentz pool pump system is about 2500 euro. There is plenty of power for filtering and vaccing, although my preference is to backwash with mains electricity as it is slightly more powerful.

In Cyprus we can (with permission) also install net metering of up to a nominal 3KW. This means we generate electricity all day and upload it into the national grid. When we need electricity, mainly at night we draw down off the grid. We only pay for the net consumption, power consumed minus power generated. Any savings are carried forward to the winter. We installed a nominal 3KW over 12 X 250W panels in 2013 at a cost of about 6000 and have not had a single chargeable unit since. Plus we've saved a considerable amount on our gas central heating by using the spare electricity generated over the summer months. Meanwhile, the pool, on its own separate system, pumps for at least 6 hours a day, summer and winter, at no cost.

I can't work out how to attach a picture, but very approximately the pool pump panels cover about 4.5 sq meters set at 45% and 3KW for domestic use is 12 X 250W panels taking up about 18 sq meters also at 45%.

Anyone really interested I can email pictures.


That sounds quite good but the Lorentz pump still needs a fair number of panels just for the pool pump?
Using the most efficient equipment allows me to run if I wanted on a small 80watt PV panel so the total cost could be much lower, roughly 850 and if the pool is more remote so not easy to get mains to it or space for a large PV array almost anywhere. That also means more power available for the rest of the house equipment, the standard pool pump could run from an inverter/battery as it's only for backwashing or vacuuming for 5-15 mins or so.
Nice to see this though.
