We have seen a lot of the roofing companies nibbling around the edges of solar
installs lately. I have only seen a couple of installs personally, and they

I have seen one install in my local area, done by PetersonDean Roofing, they
beat my bid by $1.50/watt, and actually did a very nice install, although

240.4(B) allows the ampacity of a wire to drop below the OCPD rating so
you could argue that wouldn't be a safety issue. It's always irritated
me that these NEC derating factors have two decimal places so that you

Guys,
You're missing a business opportunity. Instead of complaining about roofers'
bad work and competition, show the company owners photos of their screw-ups and
your quality work. Tell him that he is a risk. Then offer to do their design

Have any of you SunPower dealers used their modules with the fairly new SMA
line of transformerless inverters (8, 9 and 10 kW @ 120/208 only)?
I'm trying to get a compatibility answer directly from SunPower tech
