[RE-wrenches] Problem with NABCEP ad

2011-02-06 Thread wirewiz
Hello Wrenches, NABCEP has a full page ad in Home Power magazine that tells potential PV buyers to "Insist on a NABCEP Certified Installer". That's a great ad if you are certified but not so good if you are not. I know many of you are but lots of us are not yet certified. NABCEP is doing a gr

Dear Greg and others, The answer to your “paradox” is actually quite simple. It is also a great example of how a paradox can stimulate further thought until a more refined answer can be achieved. First, let’s set up the problem. You have a PV module and an external circuit. In the case of an Isc

No you are not. I have been installing grid tied PV for 10 years in ca. Nabcep is union based and all though it is good but it does not mean by any means the best as we have to fix several nabcep installed systems. I personally don't like there advertising either Aram On Feb 6, 2011, at 9:13 AM

I am sitting for the NABCEP test next month, but resisted for many years, because I did not want to endorse an additional layer of bureaucracy and expense for solar installers. It costs as much as the state contractor's license! Most of the competent installers have become certified now, so

Larry, You aren't the only one offended. It gives the impression that only NABCEP certified installers are competent, which isn't true. And that every NABCEP certified installer will do a competent job; also not a guaranteed outcome. Kent Osterberg Blue Mountain Solar, Inc. wire...@gmail.c

Wrenches, Saying NABCEP is Union based is a little bit of a stretch it seems to me. I think having a way to ensure most new installers have had training and understand concepts involved is a good thing. The lack of an apprenticeship program or state sponsored license leaves a hole and NABCEP

As PV becomes more and more mainstream, more and more organizations (including state licensing boards, unions and other certifying bodies) will weigh in on the subject of certifying installers for PV installation. We also have Professional Engineers that can provide expert opinions on the subject o

We have one Entry Level NABCEP employee. I, myself, am not certified. In our neck of the woods I have never heard of any prospective customer asking our sales reps if we are NAPCEP certified. Not one. Even our most inquisitive and well-read customers are not very concerned with certifications. They

The advantage of having NABCEP is that it at least creates the idea and maybe lays the groundwork for licensing provisions for solar installers. Here in Massachusetts, we still can't pull our own electrical permits. And by the way, that's BECAUSE of the electricians union. The whole thing has act

Wrenches, I have a mountaintop transmitter site with an FX3524, Flex Max 60, some PV and 12 L16 Bateries. They are set up in a small building used for the ski patrol at a ski area. There is a 25' freestanding lattice tower on the roof with high speed wireless internet transmitter and rec

John, Sounds like low voltage cutouts. And it is the dead of winter so the batts will be voltage depressed. Try installing the temp sensor directly into the FM60 rather than to the Hub. Also, unless those L16s are sealed, maybe bump the absorption voltage up to 30VDC or even a bit more for the w

Hi John, What is the error code on the Mate when you show up, or is there none? As far as turning on the inverter remotely, I think you would need internet on site from a DC source to let any data monitoring software remotely control when the inverter is off. Is there a back up generat

There is alot of debate in the air about NABCEP here locally. Many folks would need to fly to CA to take the exam which is expensive and many here don't see alot of value and I'll tell you a few reasons why... 1. With 150 entities performing solar work in some capacity and probably 1500+ - inst
