Last week we saw a lot of rain, making for a slippery roof and slowing down the solar installation. They were only able to finish wiring the inverter to the main panel and install the first set of rails for the lower row of panels.
This is their first installation on our type of metal roof. See our post describing our metal roof. They were concerned that the rib was a bit taller, (1 3/4″) than they encounter on ordinary folded metal roofs. They called the manufacturer (ASP) and decided to put an S-5 clip on every rib, as opposed to every other rib. The ribs are approximately 18″ apart.
Progress should be quicker now that they have the first set of rails up. Hopefully they’ll get the next set of rails and maybe a few panels up on the next clear day.
