We've had one (Solahart Black Chrome with two panels) for over 10 years. With only two of us in the house, in summer with a few consecutive sunny days it gets excessively hot, even after the bleed valve opens. It has off-peak backup and for much of the year the switch is off at the mains.
Pick one with a closed cycle and heat exchanger. In Brisbane the antifreeze they put in ours would not really be necessary but probably helps as an anti-corrosive. By not having fresh mineral laden water running through the panels it will last longer.
