Bifacial modules [RE-wrenches]

[blair may]

<x-flowed>

Bifacial modules,(Sanyo HIT Double 190W HIP-190DA3 now derated to 185W)
  are modules that charge from both sides. Pretty Sweet for cold 
snowy climates/ sun shades for porches. E mail off line as I have 
some installed if additional information/pictures are needed.

>What is a "bifacial module"? We have used the HIP 200BA3's; are they

>   1.. This temperature exclusion does not apply to the HIT bifacial models.

>   3.. The exclusion was changed (again) on April 1, 2007. Paragraph 3 (q)
>now reads, "Products installed in a location that exceeds Operating
>Conditions." It previously had the word "Standard" before "Operating
>Conditions"
>I wrote to Sanyo to get clarification of the wording in the warranty
>revision. Because the Operating Conditions spell out humidity also, I asked
>if the warranty will be void if modules are installed in areas that have
>humidity levels outside of the SOC limits. The SOC relative humidity rating
>is from 45% to 95%. There are many areas in the US that would be affected by
>this.

>Today I received response from Sanyo.  Here is the pertinent portion:
>
>   "Dear Mr. Crutcher,
>   Good morning.  I have confirmed with our engineers that the
>   current generation of modules will have either a reduced or
>   no humidity restriction.  I expect to have full
>   clarification by the end of this week, so we can
>   appropriately modify our installation manual/ warranty and
>   notify distributors and dealers quickly thereafter."
>
>Hope this helps. I like this module and look forward to selling Sanyo again.
