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: https://picasaweb.google.com/109634809794570027207/SolarWorldMonoVsPoly?authkey=Gv1sRgCMuLy4v_ivTUAg&feat=directlink Just a heads-up to anyone considering getting into SolarWorld. Happy Summer! Nik -- Nicholas Ponzio Building Energy 1570 South Brownell Road Williston, VT 05495 http://www.BuildingEnergyVT.com
