If that is the interpretation,
I don't see how the breakers are "readily accessible" in a SolaDeck
mounted anywhere, regardless of whether it is under a module. It
requires removal of four screws (using a tool) to access the breakers
inside the enclosure. It's all up to the AHJ. It has not been an issue
locally here. I can see how other jurisdictions may not
concur.​One thing is for certain -
I would rather have ​the SolaDeck out of the elements (rain, heat).
Until an AHJ requires otherwise, I plan to continue this
practice.​I guess the can of worms is
open... :)​Jason Szumlanskihttps://wisestamp.appspot.com/pixview.gif?p=chrome&v=3.32.0&t=1398701551659&u=d0c775731865b324";

The breakers in common commercially available outdoor breaker boxes are
for dry locations only, and the boxes are NEMA 3R. 
Mounting a breaker under a solar module could present a code problem, as
the breakers are not readily available.

If you are mounting under panels
(which is my preference to keep it out of the elements and for

Friends,

I just discovered that Midnite Solar also has a 3 circuit combiner
mountable down to a 3/12 pitch for AC micros at 240VAC. Â They have a
fingered buss bar that has offsets to catch every other pole on the dual
pole breaker sets.in addition it has their external lockable, visible
disconnect on the exterior of the box...

So am discovering that there are options..I
will probably use the
midnite solar option as the breakers are a small fraction of the cost of
the breakers used int he Soladeck...

Thanks for all the help...

While the interior of a raceway in a wet location is considered a wet
location, the interior of a NEMA 3R enclosure is not.. The breakers need
not be listed for use in wet locations. That's the interpretation of all
area AHJs here, and there is tons of evidence to support this logical
conclusion (NM cable into exterior mounted NEMA 3R disconnects, switch
enclosures; NEMA 1 enclosures inside larger NEMA 3R enclosures,
etc.)

I hope I didn't just open a can or worms... :)

Readily accessible is now defined in the 2014 NEC. Installing OCPD’s underneath 
a module is a major faux paux, and I can’t imagine any AHJ thinking otherwise. 
Having to remove a module in order to reset a breaker, what a drag.

requiring those concerned to use a tool, to climb over, remove obstacle or

*Fuses for PV dc circuits do not have to be readily accessible:*

690.9(D) Photovoltaic Source Circuit and Output

Listed PV overcurrent devices shall be required to provide overcurrent
protection
in PV source and output circuits. The overcurrent devices shall be
accessible but shall not be required to be readily accessible.

The language allowing j-boxes under modules has been in the NEC for many
cycles:

690.34 Access to Boxes. Junction, pull, and outlet boxes located behind
modules or panels shall be so installed that the wiring contained in them
can be rendered accessible directly or by displacement of a module(s) or
panel(s) secured by removable fasteners and connected by a flexible wiring
system.

A dc combiner is now defined in the 2014 Code as a device/equipment and
thus outlet might have it covered. I think there is an argument to be made
that a box containing overcurrent protection can be positioned under a
module. However I don't think it's a great idea and wouldn't want to
maintain a system with fuses on a roof under the array, but this seems like
a grey area in the Code and getting the AHJ interpretation would be
advisable.

[RE-wrenches] Publicity rights?

2014-04-28 Thread Rebecca Lundberg 
I have come across a new (small) installer taking photos of solar projects
that others installed, and promoting them on their web site in their
"gallery" without getting permission or giving any credit to the installer.
This seems unethical, and I'd like to be able to point to a law related to
this so that my sites are not used in this way. Even if a customer gives
this person permission to take a photo of their site, it doesn't make sense
that this installer could imply any credit for this project by using it on
their web site. Isn't there some kind of law that relates to this?

Thanks in advance for your input!

Re: [RE-wrenches] Publicity rights?

2014-04-28 Thread Benjamin Root 

Ben Root from Home Power here.

I'm not a wrench, nor a lawyer, but I do know a 
thing or two about the use of images...


"Unethical?"...yes. Though ethics are a value 
judgement, and thus open to interpretation.


Unfortunately, if the person isn't actually 
stating that the systems shown are their own 
installations, then it could be reasonably argued 
that they were using the images to represent 
generic "solar-ness" to set the stage for what 
their business provides. Even "educational" 
purposes could be argued (though not convincingly 
to those of us who know better).


If they shot the photos, then the image rights do 
belong to them and they can use them as they 
please. And if they weren't trespassing to shoot 
the subject matter (or had permission from the 
system owner), then there are no privacy rights 
being infringed upon.


If they do state that the system is their 
handiwork, then that's obviously unethical, and 
there may be legal accountability (but that's 
beyond my expertise, as it's more about false 
statements than the use of an image).


However, (and I've seen this in other industries) 
I'd bet that if you approached them on the 
subject, (not accusatory, but just as an 
FYI...educating them) they'd be so embarrassed at 
being caught, the behavior would stop 
immediately. Likely it's a new business person, 
just trying to get going, and scraping for any 
sense of professionalism to display. Instead, to 
be called on blatant unprofessionalism should be 
humbling to them.


To them a favor, by calling them out soon. And if 
they don't react red-faced and apologetically, 
then it tells you more about who they are as a 
business person than just "new and naive." Then 
maybe contact the BBB.

If you find that the "installer" has used one of your sites, you can have a
lawyer send a "Cease and Desist" letter that will probably scare them.
Other than that you probably have no standing.

Re: [RE-wrenches] high efficiency modules in U.S.

2014-04-28 Thread Exeltech 
There's also 1Soltech Dallas, Texas.

Made in the USA.  (Confirmed.  I visited their plant on a field trip with a 
solar energy club not long ago and saw their production line in operation.)

They make 60-cell and 80-cell PV ranging from 230W to 350W, and maybe others.  
They've even got a series of modules that are made with "colored" cells in red, 
green, or blue.

Not 20%+ (more like 16.0-16.5%) .. but of domestic manufacture .. and 
available.  Been around since 2008.
