Re: [RE-wrenches] ground-mounted systems, performance
The only problem I've seen was due to a sloped hillside and a riding lawnmower projectile. These modules are what refer to as the Cadillac of modules. If you have a chance to use them, you should. On Sun, Aug 10, 2014 at 10:54 AM, Rebecca Lundberg rebecca.lundb...@powerfullygreen.com wrote: Hi Jesse, I'm curious about what you are seeing. We've seen better performance than that on arrays with those modules, but don't have module-level monitoring available on any of our systems. Does it look like there is a bipass diode failure with the shattered modules (probably covered under warranty), or was there something like lightning near your ground-mounted system? We have a customer whose home received a direct lightning strike recently (no fire or human injury!), and 100% of the PV system needs to be replaced (except flashing/racking), unfortunately. I thought the delamination issues were only (or mostly) generation 2 modules and only in our state, but wonder if any installers in other places (WA?) are seeing this too? Keep Shining!

Re: [RE-wrenches] Two NEC questions
Rebecca, First off, nice install on the four SiE pole mounts! Second, as long as we are talking strictly grid-tied systems, not AC coupled or battery backup, it seems like Solar should be viewed more like an appliance. It supplements the service at your house. That being said, you've got a tough battle ahead. Hopefully someone else on the list has a great way of calming this inspector down with some good old code lullibies. Good luck! Sometimes it feels like the Solar 'cops', I mean inspectors, are trying to justify their jobs.

How will I know (before the AHJ knows :-) that residential-scale products are available for purchase, and at what point would you say now should be required over every other option? Second question: I have an inspector insisting that the solar PV system is the same as a utility service, and is requiring all of the required service code references to apply.

Possibly you could add a sheet of Lexan (polycarbonate, very tough and transparent) over the top of the array. I would think the losses would be less than 10%. http://www.modernplastics.com/lexan.html Home Depot sells a corrugated polycarbonate clear roofing panel that could possibly be attached over the top of the module. http://www.homedepot.com/h_d1/N-5yc1v/R-100049922/h_d2/ProductDisplay?langId=-1storeId=10051catalogId=10053 I've run over it, stomped it, dropped tools on it, it pops right out, no cracking.

Re: [RE-wrenches] SIlicon energy modules
Yes I have installed these modules. Yes they do have a proprietary racking system. To buy these modules I believe the manufacture wants you to do some onsite training to show you the ins and outs. Basically, its four foot on center attachments to the racking put up loose until you add the module to the racking frame. Then tighten down to move to the next module. Are you planning a roof mount? metal roof w/ s5's? or ground mount?

Re: [RE-wrenches] Heavy Duty Modules?
ditto doug, look into this module. HEAVY duty.

There is no frame on the lower and upper edge which helps snow slide off and they are laminated with thick Sentry glass by Dupont which is typically used for hurrican and bullet proof glass. We tested one with 3600 lbs of sand bags on it and 6 guys jumping up and down on it before we finally broke it. They have an interesting frame that contains the wiring and is accessible from the front. I also agree that a steeper angle and somewhere for the snow to pile up is essential. www.silicon-energy.com or call Mike Farrell mfarr...@silicon-energy.com supp...@silicon-energy.com (360)539-1851 cell (425) 319-2780 Bill Bill Hoffer PE NABCEP Certified Solar PV Installer™ Sunergy Engineering Services PLLC 2504 Columbia Ave NW East Wenatchee WA 98802-3941 suneng...@gmail.com (509)470-7762 Cell(509)679-6165 ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org -- Alex Cozine NABCEP Certified Solar PV Installer™ Brothers Electric Solar brotherselectricsolar.com ___ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org

Re: [RE-wrenches] metering an outback system
Yes, you are correct. The Solar pro diagram and article is great for understanding each mode the meter can be in. On Tue, Aug 10, 2010 at 5:57 AM, Drake Chamberlin drake.chamber...@redwoodalliance.org wrote: Hi Alex, The one meter hook up always seems confusing to me. I'm still confused. Do we have the AC IN at both the bottom left and top right? To me it seems that the AC OUT from the inverter would go to the upper left and the protected loads panel would be fed from the bottom left. I've never used this method, but would like to use it instead of the two meter method.

Re: [RE-wrenches] Enphase System Labeling
Ditto Kent. And thanks Marv for submitting changes. Explaining to the AHJ that it is ok to install enphase without rooftop disc switch is much easier with clear instructions from the manufacturer.
