[RE-wrenches] Inverter sizing

Hello, I have been looking at some archived threads (lots of knowledge on here eh?!) about inverter sizing. The temperature swings in my area (100 degrees F to -55 degrees F) are making me stay up hours finding inverters and modules that don't clip during the cold snowy months when it is clear

Silicon Energy. Their plant in MN is fifteen miles from me and i have been through their training. We put two very large gentleman on a module it took it like a champ. I recall them saying something around 150-180psf. I just got back from a RFP release for a silicon energy project. Lots of sno

Re: [RE-wrenches] High PSF Mods?

its a busy Wrench List day for meWe have many REC's in the Bahamas for that reason Jeff. Both systems on Cat Island that we had were hit with 130 mph winds by Irene and except for one charge controller getting wet on one of the systems, they both survived. One system was roof mounted, the o

Re: [RE-wrenches] High PSF Mods?

The Canadian Solar CS6P's and SolarWorld 245 Monos are rated to 113 PSF. I don't really like the 31MM frame on the SW from a wind/snow load perspective. It just seems like there isn't enough aluminum there. But who am I to say? They do look great! The CS6P-230PX Zep framed module just FEELS lik

Re: [RE-wrenches] High PSF Mods?

I second the opinion on Silicon Energy modules. Our crew doesn't hesitate to walk or climb directly on the modules when they need to. They also have good impact resistance. We installed a 75kW system on a flat roof at a middle school and walking around on the roof, you would guess that it had been

Jeff Sorry random keyboard typing caused a pre-mature send... Silicon Energy should be at SPI this year and they are manufactured now in Washington State and Minnesota see www.silicon-energy.com for details Bill On Tue, Sep 27, 2011 at 3:18 PM, Jeff Clearwater wrote: > Hello Again Wise and

Re: [RE-wrenches] High PSF Mods?

Jeff Silicon Energy has a 125 PSF rated module which slightly exceeds 5400 Pa ( 113 PSF). I would guess that it can actually handle a lot more than that. Good looking module with a cascading mounting system included that also makes a clean raceway for the wiring for a very clean install. Framele

Hello Again Wise and Knowledgeable, What's folks favorite modules for high psf ratings? I know RECS have high ratings. Others? Thanks! Jeff -- Jeff Clearwater Village Power Design Renewable Energy Consultant 32 Years in all Aspects of Renewables www.villagepower.com skype: jclearwater 413

Thanks for reminding me RayJeff, we use ss transition boxes instead of pvc. You can find 6x6x4 or 4x4x4 boxes for a reasonable price considering their superiority when it comes to longevity. Obviously use at least 3R rated boxes at a minimum. Daryl DeJoy NABCEP Certified PV installer Penobscot

Re: [RE-wrenches] Salt & Aluminum vs Galvy

Galvanized does not do very well in Hawaii near the water. I haven't seen much powder coated Al, but anodized AL with SS hardware seems to work about as good as anything I've seen. We see SS J boxes, fiberglass boxes seem to break down in the UV after several years, but painting with the right

Re: [RE-wrenches] Salt & Aluminum vs Galvy

Hi Jeff, There is no doubt that aluminum will stand the test of time better in a marine environment than galvanized steel. The galv. will show rust in an amazingly short time. We have had DP&W marine grade aluminum mounts within 50 feet of the water in the Bahamas installed now for more than ten

[RE-wrenches] Salt & Aluminum vs Galvy

Hi Esteemed Wrenchies, So for the project I'm working on in the Bahamas for ground mount racking - have folks found Aluminum or Galvy to stand up against salt spray better? And if Al - powder coated or anodized? And with mixing them - (like a typical Steel Pipe rack with Al Rails) - are th
