Solar pool pumping

The new season starts.... and thousands of pool pumps will run every day and use massive amounts of energy...
one is yours! and will be responsible for (average home) approx 15-25% of your electricity bill.

get rid of that and install a solar powered pool pump, payback is approx 5 years only.

HELLO,
a 10meter x 5meter x avarage 1,60 meter deep pool contents approx 80 tons.
in summer, this pool needs to be circulated minimum 1 times, better 1,3 to 1,5 times.
if you do less, this only can be compensated with high chlorine levels which are surely not healthy.
actually they are very unhealthy, causing several "vexations", as stomach problems, breathing problems and so on.
an average 1 kW AC pool pump circulates approx 10 tons an hr.
in summer, this AC pump must run therefore 10 hrs minimum and in a yearly average 6-7 hrs per day.
say: per year 500 to 600 euros electricity costs.
a solar pool puming system which replaces the AC pump for a 8x4 or 10x5 pool does cost approx 2400 to 2700 euros.
- stg rates to euro at the moment very good: = 1750 to 1950 STG.
- no special permission needed from KIBTEK.

kind regards
kibsolar

Could you confirm the life expectancy of the solar pump?

I presume that the solar array will need to generate an average of 1 KW of electricity (or perhaps a little less) throughout the working day in order to be able to provide the power to shift 100+ cubic metres of water per day, and unless a 'steerable' solar array is used, it will be working at less than optimum efficiency for quite a portion of the day.

In an average situation, in TRNC, what is the physical size of the solar panel required - in square metres? Can it be mounted 'out of the way' - say on the roof of the house? - or does it need to be in reasonable proximity to the pump?

Assuming that there is the option of using a steerable array, what effect does this have on the size of the panel required, and what is the effect on the installation cost?

a solar pool pumpinG system "set" contents
- the PV array and the stands (on roof, garden, wherever... if far away, we need a bigger cable cross section)
- a pump controller-inverter, preferably in pool room
- the pump
- wiring, piping, labour, VAT
DC pumps in general have a longer lifetime as AC pumps and all our pump systems from 2006 are in operation

correct, the PV array for a 10x5 pool is around 700-1000 Wp.
final output depend on existing piping, PV array orientation and so on.
all customers will get a personalised pump report for their system to verify the expected output.
very reliable software, provided by manufacturer, also used for well pumping and other surface pumps.

"tracking the sun" is too expensive and in general "one PV module more instead" is the cheaper solution to compensate losses.

I had my 8X4 (deep) pool converted to Solar pumping by Kibsolar over 3 yrs ago. It uses 3 standard FIXED panels close by, providing probably 750w (peak).
There is no need whatsoever for Tracking Arrays and their cost.
Even on a cloudy winters day when power may well be down to 100w or so, the system keeps the DC pump running from sun-up to sun-down, albeit at a lower rate than on a sunny day.

The other benefit on top of electricity savings is that to have the pump running all day long, summer and winter, keeps the pool cleaner, requiring less chemicals and makes the filter sand last considerably longer. Pool maintenance costs are therefore considerably reduced.

My pool maintenance firm have been very impressed!

Kibsolar claim a 'payback' period of around 4 years. Mine has achieved 'payback' in 2 1/2 years!!

The DC pump is far quieter than the original AC pump, and is a high quality German pump which will probably outlive me!

If anyone would like further info from a 'satisfied client', please feel free to ask me.

Thank you Kibsolar and owl!

I'm not really thinking of changing at the moment, but you've certainly provided useful information for anyone who might be ready to 'take the plunge'

The point about the longer life expectancy is a good one, because I understand that a lot of pool pumps 'die' as a result of power cuts and 'brownouts' (reduced supply voltage, which causes excessive current consumption) - and even without the benefits of German manufacture, complete non-reliance on the TRNC 'grid' can only serve to improve reliability...

As an aside, I do remember our friend 'TRNCVaughan' remarking that solar pool pumps have the advantage that when the weather conditions are such that they promote the growth of algae (i.e. 'sunny) - then the pump can work harder, because it uses the sun as well, and when it's not so sunny, you don't actually need the pump to run as much! - a very convenient situation

Thanks again to you both.

yes,
owl's system has a payback of 2,5 years, because he is off-grid.
but usually we calculate the said 5 years.
often this is "not true", because many pool pwners does not realise "how bad" their ac pumps work in practice (lower circulation as expected = pump should run much longer), and payback is after 4 years...
our pump systems are designed that they deliver the necessary amount of water during the summer month and, naturally, this will drop during the winter month to approx 50% in average per day.

We have many potential customers who do understand the advantages of the solar pool pumping ( and also net-metering systems) very well, but say also:
I'm not really thinking of changing at the moment...
4 or 5 years payback represents an interest rate given from a bank of 20 or 25%...
are the "solar investments" still too high?
does "the customer" expect a payback of 2 or 3 years?
THIS never will happen...
Regards

A major factor in 'Solar' pay-back period is the cost of electricity.

Since I went 'Solar', Kibtek have increased prices quite dramatically. This has reduced my pay-back period.

If Kibtek continue to INCREASE prices, your return on Solar investment get's better & better.

If Kibtek REDUCE prices, Solar is less attractive as an investment.

A simple question: Which way do you see Kibtek prices going??

Hi, probably a daft question but can an existing pump be converted to run off solar? I ask because ours is quite new and was an expensive one.

Hi Peter

Ive tried phoning you but no answer, tried a few times.

You installed a solar pool pump system in my villa (Kucukerenkoy) less than 2 years ago.

Can you please phone me relatively urgently as I have an issue. 07460944911

Kind Regards Mr O.
