Re: [RE-wrenches] Haticon Mid and Ends

2015-10-06 Thread Bill Loesch


James,
Glad you received at least one potential source for product, so far.
With all due respect, why do you need to replace the clips?
Any take away for others so as to not have this same issue?
Thanks,

I believe we need 40mm and 31 mm ends.

These are for old installs where the customer is re-roofing and we

Re: [RE-wrenches] PV testing

2015-10-06 Thread Chris Mason
If you use the PV150 tester, it will do this test, giving you the Isc for
each panel you test. The Isc should be the same for all panels given the
same irradiance. It does all the other tests at the same time, and you can
record the results to an Excel format report, including the irradiance at
the moment of the test.
As you can string test, which will identify any strings with bad panels, I
think this should be a minimum for any commissioning report.

An Isc test will not find a series resistance problem.  You have to put a real 
load on the panel or string to find this type of problem.

I agree, many module failures only show up under load.  I just use a 
clamp on meter while the modules are still wired to the batteries.
The PV150 can capture operating current and power as well, so it should 
be able to identify most module fails.  I'm just not sure if it can do 
this without a load.  I don't believe it's an actual IV tester.

Hi Wrenchers,

I have found on the older panels, especially the AstroPower line,
the problems tend to be bad solder joints.  This shows up as a
series resistance.  As such, the open circuit voltage and short
circuit current will read good.  It is not until you put an
external load on the panel that you will see any problems.  If
you want to draw out a simple circuit with a voltage source, a
current source and a series resister, you will see this quite
clearly.

On these older systems I am just looking for the few bad panels
to be replaced or fixed (more info on fixing if requested).  I am
not looking to find the MPP output or the corrected performance
of the panel with all the relevant parameters accounted for.  A
very easy way to do this is to just have one or two 50 watt 12
volt halogen bulbs as a load and measure voltage and current
across each pane with this load. I try one bulb and then two
bulbs in series and use whatever set up gives me the highest
wattage reading and then use this load for the rest of the
testing. Bad panels (AstroPower) tend to be 1/2 the output
relative to the good panels, or almost no output at all depending
on where the bad solder joint is.

If you have a bunch of panels you can take down the measurements
and then sort through them and get the best panels for your
system (I have an excess of panels at this point).  It is helpful
to have an irradiance meter to make sure you are testing all the
panels with about the same input for comparison.  The panels of
course have to have about the same angle to the sun and similar
temp to make the comparison valid.  I usually have the panels in
the shade and then pull them out for testing so that the temp is
all about the same.  They can also be tested in place if you can
access the leads for testing.

I have built a tester with several bulbs and a toggle switch that
will let you easily switch between Voc, Isc and with a load using
two meters, one for voltage and one for current to make the
readings at the same time.  No fancy testers required for just
finding the few bad panels.

They need anti-seize lube on the threads.  Also, I would not use power 
tool/ impact drivers to tighten them, they not only can over torque 
them, they spin too fast which causes the bolt threads to gall. Check 
with S Flex, I believe they are using a coating on their hardware now 
that alleviates the galling.

[RE-wrenches] DPW Rack Problems

2015-10-06 Thread Ray Walters

Greetings All;

I have used DP&W's top of pole racks for 20 years, but I've had my share 
of trouble, too.

First the lead times are horrible, sometimes pushing 2 months.
Second, the cost is approaching the cost of the modules, especially for 
high wind ratings.

Third, they just can't seem to wait till the paint is dry to pack the racks.
Several times I've had to sand and repaint the main strong back, because 
foam, paper, or plastic wrap had stuck to the paint.
This last time was the worst, and I was offered $50 for my troubles and 
embarrassment in front of the customer.
They said I should have shipped it back.  How much sense does that make: 
round trip freight shipping, and 2 more weeks lost?

Here's a page of the manual completely stuck in the paint:


Come on DP&W, you guys used to stand by your work.

RayWe have had the same problemsBut we didn't get offered the $50
for our time and labor.
We called and complained...it seemed on deaf ears.
AlsoThey advertise pre -antiseized bolts on some of their
rackingbut it is certainly not so with their top of pole racks.Some
times the gimble bolts have anti seize and and sometimes not.lack of
consistency is a head ache
We are exploring alternatives..

These have all been a long standing problem for us as well, getting
regularly worse!

2015-10-06 Thread Shasta Daiku
Glad it’s not just me. My supplier jokes that I have bad TPM karma. 5 of the 
last 6 racks had major problems that shut my projects down until replacements 
could be made and sent. Snotty customer service too. It’s a bummer since I’ve 
been using their racks since their beginning.
