I was wondering what issues people have had screwing/bolting mounting feet to a metal roof with thermal expansion.

I was looking at a european roof mounting foot and noticed they cut a hole in the metal roof, and screw the foot to the sheathing using a rubber gasket to make a water tight seal to the metal roof.

Jeff, Joel, William and all,

Thanks for all the input. I think the general consensus is that giving out wholesale price information is not a great business strategy - on this list or anywhere else.

I'm glad the PV pricing thread morphed into Professional Conduct. There was a lot of really good advice in those posts. I think you saved a lot of us "lurkers" some scar - tissue!

Thanks again,

I seem to remember mention a while ago of a quality charge controller that
supports a higher input voltage than 150 V? We would like 175 V.

Hi Peter,

Apollo makes a high voltage 200VOC unit, 80 amps.

And the Classic from Midnight is almost ready to come out if I hear it
right.

That will be the MidNite Classic, Peter. They aren't quite ready for
production yet, but thaere are promising Beta units in the field. 200
VDC I understand.
