Keith, it wasn't just the lack of air gap.
As the brand struggled under the old regime, cheap "solutions" were found, one of them being cheap Chinese thin panels of poor quality. Also cheap Chinese crappy solar regulators. And cheap, undersized wiring. All contributed to poor performance of the PV system.
Also, the method of fixing to the roof. The method chosen promoted stress in the panels, with some of the conductors in the panels cracking.
The new owners of the business have sourced high quality thin panels from USA. The manufacturer recommends flush mounting (ie, no air gap to speak of) with industrial double-sided tape.
