NABCEP Call for comments [RE-wrenches]

John,

I am all for some type of certification which will hopefully prevent
unknowledgeable people from connecting solar power to the electric grid.
The last thing our industry needs is for substandard installations to
become commonplace, resulting in a black eye for all of us.

With that said, a sizable percentage of the grid-tie systems being
installed in southern California are not installed by electrical (C10)
or solar (C46) companies.  It is the large HVAC companies who are
selling and installing the most systems.  I would hazard a guess by
saying that these companies have probably never heard of NABCEP.
Personally I have been happy to see large companies with infrastructure
get into the PV field.  I feel confident they will not disappear when
the rebates end and will provide service and support to their customers.
My company is small and needs to remain so until PV can be sold without
incentives.  I have to keep my overhead low in order to remain active if
and when the rebates expire.

The only way I envision NABCEP becoming viable is to either have a
massive and expensive marketing campaign that makes all potential PV
purchasers aware of this certification, or for NABCEP certification to
become mandatory in order to acquire permits.

Another developing trend in L.A. is for homeowners to purchase equipment
and install it themselves.  I have had three homeowners call this week
asking for advice on "the type of wire needed and how to mount the
panels"  Two of these homeowners have 40 SP 140's and 2 Sunny Boy's.  I
advise them to use XHHW-2 wire and to reconsider self installation.
These are the systems that worry me the most.

I am wondering if PV salesmen who get paid on commission should have
some type of certification.  I may be wrong but I believe many systems
are being sold on STC x 6 hours.
