I know it was not the question but on the light dimming, it might need to be
controlled / corrected or the new pump is going to really set it off

What is the inverter?
How long is the wire run to the inverter and is it 4/0 cable?

Please keep in mind that old, 12 volt, non-UL PV modules can have an

I see several challenges here:
·You sure do not want both pumps on at the same time or total
shut down will result.
·The 2HP pump is 24 amps at 120VAC or 12 amps at 230 VAC,

I am frustrated by the lack of response from the folks at NABCEP regarding
this type of comment.
Is anyone from NABCEP out there? Any thoughts on this???
To bad this wasn't discussed/addressed w/ UL prior to their launching.

Whether you rebuild the system using existing equipment or start over again
with all new gear, I strongly suggest building a simple relay logic control
to prevent both pumps from running at the same time. Toilet flushes,

Hi, Wrenchies~
If code compliance were not an issue, one might connect a Photowatt 47 in
parallel with a Golden Genesis 75 to effectively yield a 122 watt unit
around 17 volts @ max power...and those two resulting units could then be
connected in series with the two Kyocera 120's to create a

Have any of you had any experience with the Corrubracket

them? Are there any better methods for attaching to corrugated roofing?
Thanks in advance.

We are just completing a non-penetrating roof mount in a beach
environment. We chose aluminum rigid for our PV feeders. Cost about 1.30
per foot, easy to work with (for real electricians -- you need to have a
threader and rigid experience). I recommend it.

Does anyone here have experience with designing and installing Kaneka
thin-film PV arrays?
I am seriously considering them for an upcoming multi-site off-grid
install at a Northern BC Canada fishing lodge, where everything has to
fly in 135 miles by float plane and then

Can anyone DEFINITIVELY tell me whether the DC systems on AEI Solaron based
plants is grounded or ungrounded during operation?
Have you tested your theory in the field? What marking requirements do you
suggest for the neutrals?
Thanks!
Matt Lafferty
Hi Dan,
Not sure if I qualify as esteemed or not. My experience with Kaneka
products is positive all the way around. Haven't used any in the last 4
years. Prior to that, here's my take:
Kaneka's fit and finish is superior. (This is QUALITY stuff)
Electrical output is reliably over nameplate.
All of my this ought to work? experiments in module mixing and matching did
work, but always under performed.
If the customer wanted to play around with them, put them on a decent rack,
and hide the mess from view, it will still provide some usable amps.
I wouldn't even waste an MPPT controller
Matt,
They claim to use a bi-polar array with 600Vdc per pole. All bipolar arrays
must be grounded, so they must be grounded. They claim to be grounded
through the ac service transformer while operating. They are fundamentally
similar to many ungrounded designs. So, it IS grounded during

Anyone have a line on a well-priced Solmetric Suneye 210?
The cheapest I've found so far comes to a bit under $1,900.

Esteemed or otherwise, we installed 6 Kaneka 60W modules on a solar stock

performance.
We are preparing to install 8 more of them on another solar stock watering

I still think the venerable Solar Pathfinder coupled with their Pathfinder

I did some very detailed shading analysis with the Pathfinder (as you may
