[RE-wrenches] The Demise of WEEB

[Bob-O Schultze]

Ray,
Your picture is clearly one of an aluminum lug with a steel screw. I would agree that this lug is unacceptable, but this is NOT the lug which is commonly used and has been used for many years. While you apparently are infatuated by the WEEB device, not all of us are. Could you please do us all the service of recanting?
Thanks, Bob-O

Here's a traditional Ilsco Lug after less than 5 years near the ocean:

IMHO, this is a galvanic reaction between the Cu, Al, and (our loser) the Lug which became the anode.
No other corrosion was near this state of deterioration (frames, etc), and ALL the lugs looked like this on most systems I've seen over 3 years old on Maui.
I've seen advanced Ilsco lug corrosion in New Mexico as well, so don't think you inland folks are safe.

My fellow wrenches, this is NOT a good way to ground modules.
The WEEB is not just faster to install, it is a vastly superior connection, and is now being accepted by most AHJs; its also stainless steel.
Can we please continue to move forward into the 21st century, Sunpower? Your modules are the best, don't make us go backwards.
