Thinking of getting them and using them for heating hot water and might try heating the house.
looking for some honest feedback where they worth the cost, any issues with set up etc did the do what the said they would do?.
any feedback much appreciated

Personally, I would go with Solar PV in place of solar hot water as electricity costs 3-4 times per kWh as gas heating.

And with solar PV, you only typically self consume 10-20%, the rest goes back to the grid for free. Unless you have a battery, but these are extremely expensive

Unkel, agreed in the main but self-consumption rate will also be much higher if you have an electrical heating system; an EV will also help. I've both (an A2W and an EV) and was at 67% self-consumption (and 24% self-sufficiency) last year.
Not that I'm against export, by no means.
Aligning PV with an electrical heating system and EV seems to me the way to reduce the footprint. Although heat pumps are really expensive and the energy-mix in grid power is for now still a massive issue for both A2W and EV.

Disagree regarding the energy mix comment, the Irish grid is pretty good already and C02 intensity is reducing every year.
EVs and heat pumps offer great benefits to human health from improved air quality where people live.

A lot of flawd logic in your argument.
