NABCEP Call for comments [RE-wrenches]

[Bill Brooks]

John and Graham,

I am afraid bad installations are becoming commonplace. There are far too
many people doing installs that haven't the necessary background to do the
work. I think that there are far too few controls on the CEC program to
prevent poor systems from being installed. I do believe that the
manufacturers have a role to play by establishing authorized dealer
networks, but I believe those providing incentives (CEC, NYSERDA, etc...)
need to send the right signals. Requiring NABCEP certification at some point
to receive rebate funds is not an onerous undertaking for a good installer,
but it will weed out many poor ones. It is only one of several reforms that
should be adopted soon if we want the industry to grow.

I also firmly believe that there is far too much "design" work going on in
the PV industry right now by those who are clearly underqualified. Although
this will not sit well with many, I believe that system designs should be
fully engineered and fully documented so that a competent installer will
know exactly how to install the product properly, and achieve very
predictable results. We are not anywhere close to that situation right now
in California so we get the whole range of designs and performance from
excellent to extremely poor.

How many grid-connected systems are being messed up as we speak? I don't
know for sure, but I am willing to bet it is in the 20-50%. Is this a
problem? I'll let you draw your own conclusions.

Maybe we won't have a problem with running out of rebate funds soon because
no one will want these unreliable systems anymore....

Bill.

Graham:

The self installs are a concern to us as well and we try to discourage
it.
In addition to the numerous safety and performance issues we the owner
builders require about 10X the support from us.  As you might imagine
the some of the guys willing to sell components direct to homeowners are
not exactly the most supportive after the sale.

We are trying to find a way to address this without crossing the line
into restriction of trade.  An authorized dealer program is one way but
we want to make sure we have a solid program that is of value to the
installers out there.  Suggestions are welcome.

If you have any questions, or if I can be of any further assistance,
please do not hesitate to contact me.

Best Regards,

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.
