Re: [RE-wrenches] CIS mods

This could just be due to the better temperature coefficient, or maybe they do slightly better than cSi at lower irradiance levels? Solar Frontier CIS: -0.31%/degC SolarWorld poly: -0.45%/degC I don't know enough about CIS to comment on the light soaking. On 2013/2/18 8:36, Marco Mangelsdorf w

Re: [RE-wrenches] CIS mods

Doug, I could be wrong but I don’t think that definition of soaking is correct. Typically it takes 6 months of good sunlight minimum for a module to reach a stable output, this is particularly true of A-Si . For example a US64 will degrade 15% and then settle at the label rating after 6 mon

Re: [RE-wrenches] CIS mods

Light soaking = exposed to sunlight for some period of time in order to complete light induced degradation (or apparently light induced enhancement). Best Regards, John Berdner General Manager, North America [cid:image001.jpg@01CE0E09.55EDDEB0] SolarEdge Technologies, Inc. 3347 Gateway Bouleva

Re: [RE-wrenches] CIS mods

Ok so its a reading night. There are a bunch of very good papers about this effect on all the different types of modules. www1.eere.energy.gov/…dfs/pvmrw2011_p25_tf_dunn.pdf Best summary of Soaking would be : controlled exposure to light under controlled environmental conditions. The "soaking"

Re: [RE-wrenches] CIS mods

I don't understand the text as stated.I am not sure if they are simply referring to a common effect in most thin film panels where for the first few months they can output more than ratings, and then they settle down to what they are rated for, or if they are saying that after a few months the

Marco. Did you notice the claim in the text as follows. The "Light Soaking" Effect Following an initial period of exposure to sunlight, the CIS light soaking effect will result in higher output than factory spec. This has been proven by field data from around the world If correct this a

The Simpson screws look very similar to the Headloks. I just looked at the Simpson SDS, and I see they are available in 316 Stainless as well. That would be my choice near the ocean, but I'm guessing they're spendy. R.Ray Walters CTO, Solarray, Inc Nabcep Certified, Licensed Contractor 808 269-

Ray: We use the Simpson 1/4 by X" "Strong Drive" (SDS series). We get them in the hot dip galvanize version. They are readily available locally. I think building officials like the Simpson name on structural products. They self drill and we have had no instance of them snapping off while

I've got a project right now on a steel roof. I was just at a trade show last week, so I got to look at the latest gizmo from S5. I didn't like it at all, it didn't go into the valleys like the old mount, but drilled 4 holes into the side of the ridge, and just counted on the roofing to hold th

Re: [RE-wrenches] Corrugated roofing mounts

Chris: We have used the S5 corrugated product before and choose not to repeat the experiment for these reasons: 1. Making roof perforations in any valley defies common sense. 2. The threaded mounting holes stripped very easily. 3. I have determined that most common wavelength of corrugated r
