Probably about right ,you'd get a bit of heat off them on a bright winter day , but it's not a huge amount...
There's a Couple of things that might affect it though..
Is that tubes or flat panel ?
West facing probably not the best. .... Do you know are the panels at the right angle / is anything shading them at Anytime ?

Solar thermal works well, but is expensive (even after subsidy). It only makes economic sense if you use lots of hot water. Solar PV is really cheap these days and also gets a huge subsidy. It is very inefficient to heat your water with PV, but it makes sense if you are going for a large PV setup anyway and your current way of heating water is expensive (as in you're currently heating it with an electrical immersion or with an old and inefficient gas or oil boiler)

I'd leave it well alone. You already got the subsidy, you won't get it again. Concentrate on other (renewable) investments first. Like insulation your house, get a high efficiency boiler and rezone (subsidy $), solar PV (subsidy $$), or even better, an EV (subsidy $$$$)

The house was built in 2014 so it’s well insulated already and I wouldn’t be eligible for any subsidy’s. It’s just frustrating having a panel and it being fairly useless

Today, the roof panels are about 40 degreesC with the slight bit of sun - I have the Nutech control panel set to winter mode. The panels are not hot enough to be of benefit to heating domestic hot water cylinder.
