Kris, Yes that is correct. If you look on the tax form 1040 itself, the logic proves that.

Re: [RE-wrenches] Back sheet covering
Mac, Yes, we used a silicon based paint and covered the UL label with a detachable sticker. We got the manufacturer to approve it. The silicon paint did not appear to interfere with the cooling of the module in our very limited testing. Screening with solarscrim would probably also work and accomplish two purposes, protecting conductors and screening the color. Good luck.

Re: [RE-wrenches] Sanyo HIT module diode issues
Thanks Dave, We have installed many systems and we only had this problem with Sanyo modules and we had a rash of these crop up about the same time-frame and the issue only affected part of the array. Panasonic denied our claim because they stated it was a lightning strike. The cause is inconclusive in my opinion.

[RE-wrenches] Sanyo HIT module diode issues
Hi Wrenches, We were installing Sanyo HIT modules back in 2006-2007 and in 2014 we had a rash of bad Sanyo modules. The modules had distinct voltages below the good modules ie 50% or 75%. Sanyo at the time (now Panasonic) indicated that it was a bad diodes from a lightning strike not covered by warranty. I finally got around to checking that out. I identified the purportedly bad diode in one module (four per module) that was performing at 75% and removed it. The diode appears to be fine using an ohm meter. Is that a valid test? Anyone else have similar findings or experiences with this? Could lightning blow apart the tab ribbons inside of the module?

Re: [RE-wrenches] Sanyo HIT module diode issues
Hi Brian, Thanks for the info. Yes I tested the diode properly. I was concerned that I needed to test the diode under a load to get a valid test.
