new standing seam metal roof- clamp to ribs/ rib height question

Hi all, we are looking to install a standing seam metal roof. Our roofer has recommended upgrading and getting 1 3/4 inch high ribs instead of standard 1 inch ribs. They will be 16 inches apart. He says the 1 3/4 inch ribs will allow for clamping solar panels right to the ribs without drilling, but the 1 inch will not. Of course, they are a lot more expensive, maybe 30% more, just for higher ribs. Will this really make installing panels easier? If it matters, the metal roofing is design span hp by asc building supply. Thanks!

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6

PG&E Aggregate Net Metering Application Help

PG&E Aggregate Net Metering Application Help Earlier this year I completed a ground mount at a ranch in Paso Robles, CA. This ranch has two meters, requiring me to complete the PG&E’s Aggregate Net Metering Agreement. 8 months later my application has been rejected multiple times. I’ve spent dozens of hours on the phone with various support services with no solution. I’ve given it my all. Does anyone have any contacts for professionals who I can hire to complete this process for me? Or any tips for completing this process? Honestly, this issue has become the bane of my existence and I need it solved. Any help is greatly appreciated.
