Indeed it does.
Assume this is the product?

Is it worth considering?
The sales pitch for the CoolPV suggests it is a niche product. It targets pool owners who need pool heating and want the benefits of solar PV. One that also solves the problem of limited roof space facing the sun.
If it is such a great solution, how many or how few competitors are there with a similar product?
It could be an emerging market. Hence very few. Or a very limited market and only customers who will pay a premium/compromise to use limited roof space?
However if the product is cheaper than two separate systems the market might be very large? Pools are very common and one of the bigger expenses of pool ownership is the cost of running the pump. Something you can run in the day time for free off solar PV. Some are always looking to get more use out of the pool for longer in the year so the heating would appeal.
Is it cost effective?
Does it perform as promised?
Is it reliable?
For heating a pool which can utilise low grade heat it may be cost effective?
Is the “Cool PV” solution as cheap as buying a separate PV and Pool Water solar heating system? This assumes there is enough suitable roof space for both.
It may help others in the community in the future if you decide to get comparative quotes the overall results might be shared.
It would seem reasonable to expect any quote for a “Cool PV” system worth considering would come with written performance guarantees. Annual energy production from the PV and also for the thermal performance of the pool heating system.
@meltam has offered some useful feedback on other considerations including reliability, reputation and reviews. Given typical solar PV panels are offered with very long warranties 10 years plus for the panels and 25 years for performance, you expect them to last a very long time. Is the wet system design in the “CoolPV” product going to last as long with minimal performance loss or failure?
A bit of cynicism:
The marketing material talks about “UP TO” often. That has no real value except as virtual loo paper. To counter this the panels have both electrical and thermal performance data appended to the marketing material. So the CoolPV system designer should be able to provide complete performance outcomes for each specific location.
Yes! it still looks good on paper!
p.s.
Some points to ponder.
We’ve had pools in three houses and appreciate that they can be too cold for comfort. The further south you live the greater the need for heating. In the north of Queensland we found that we needed the opposite (pools can get too hot) for half of the year.
A contradiction might be that in mid summer when the solar PV panels get hottest the last thing needed is a hotter pool, and turn the panel cooling off! But in mid winter or if the pool is way down south the air temperatures are cooler and strength of the sun weaker. Under those conditions the total panel output and hence efficiency benefits of cooler PV panels will be much reduced (halved?).
How effective the “CoolPV” panels are at transferring thermal (heat) energy to the pool water will also vary. The panel data sheets provide results for a nominal scientific standard set of conditions. A guide only. They are not representative of the real world. The energy transfers/benefits will depend on your latitude (North/South) roof orientation, day of the year, weather/clouding, pool water temperature, etc.
As an aside.
The following paper illustrates the potential for efficiency gains through cooling on yesterdays technology PV panels. And just how nerdy this topic could become.
