I understand that battery gassing of Hydrogen Sulfide can set off CO
detectors. A new customer who I am about to replace a large battery bank
for had his furnace tech on site today to check for proper operation of the
furnace since his CO detector was going off, the tech found the high l
Marco:
I had one commercial project using the Uni-Solar "PowerBond" ePVL-136 PV
Laminate (136W / Roll). They also make a 68W and 144W roll. It can be
installed on either membrane or standing seam metal roofs. The product
has to be installed by a certified roofer (at least it did 18 months ago)
Perhaps another solution- using a roofing company to spray a layer of foam and
then a silicone over that.
They offer a 20 year warranty.
You can first install your mounting equipment and they'll foam around them.
Its about 1" thick for the foam and 50mm-100mm for the silicone.
Costs about $5 sq f
I have a client with a big commercial warehouse (metal-framed).
He needs to replace his metal roof and is asking whether I know if any kind
of reputable, listed product might work which would act as both the roof
membrane AND PV array.
That way the cost of re-roofing may be somewhat covered
After swapping a major manufacturer string inverter 4 times over a two
year period, and not knowing why, I can say unequivocally that I don't
want to deal with that again. Talk about customer frustration... At
least in a micro installation, the system remains functional when one
microinverter goes
A lot of my initial meetings with customers go like this: budget, array
location, "how do I know if one module stops working", they have read in
articles about micros module level data and really want it.
That's what I see as the driving factor here. Our winter temps keep them out
of the mark
As I look out on the market place here, it must be close to 100 to 1, micro
inverter installations vs string on residential systems.
Don't know what the primary reason is, but I sense simplicity, as there are
less "wrenches" out there, so to speak.
