If you are re-roofing rather than adding it to the horrid fake tile roof, get specs on where they want the purlins from the solar guys, because depending on where they are they may not be able to get the coverage that you want, since they determine where the brackets can go, and the last thing you want it to have to have vertical rails.

Huh, So looking back, last time I tried to get a quote was late 2020. Harrisons was one of them.

Yours looks good.

I'll be getting in touch with harrisons and rheem. Solarman seems to be Wellington only.

And someone else - anyone have any north shore Auckland recommendations for a metal tile (decromastic) roof?

@Stu1

I've had two quotes now, and the Gerard roof brackets seem to add quite a lot to the install. That looks like what you used.

30 panels, split across two roof surfaces, 10kw inverter, $31k.

Approx 6k is the roofing brackets.

How much did you spend?

@timmy did you have rails on your install?

@richms - excuse my ignorance, but what do you mean by "last thing you want to have is vertical rails"?

Do you mean having the rails (which the panels mount to) running vertically up the roof (e.g. parallel to the long run corrugation?)
Or do you mean something else?

As wouldn't the rail orientation change, depending on whether you were having the panels orientated in landscape, or in portrait layout?

Yes, going up and down means more needed as it's on the short side.

If you do landscape panels then it can go either way but if the purlins are in the right spots then it will let the panels have the brackets spaced better and not too high or low on the roof.

Might mean one or 2 more purlans but that will mean better places and attached solar.
