[RE-wrenches] SolarWorld Poly

[William Dorsett]

Nick, that is a huge amount of difference. Like you, I would suspect the
lack of antireflective coating. Please let us in on any Solar World
response.

Esteemed Wrenches,

I have been using a lot of SolarWorld mono-crystalline modules this year and
I am quite happy with the product. This week we installed our first
SolarWorld poly-crystalline array. I was surprised at how different the two
modules are. The glass on the poly module is highly reflective. I went so
far as to call my distributor to make sure I hadn't gotten a bad batch that
missed the anti-reflective coating step. That's what it seems like! 

The other significant difference is the frame style used. The Poly are only
compatible with top-down clamping. I was aware of this from the datasheets
but I had no idea that the glass would be so different. 

Take a look at some side-by-side photos here:

Just a heads-up to anyone considering getting into SolarWorld. 

Happy Summer!
Nik
