SanTan has used panels for sale in the following categories. With their latest sale, they seem to be pricing all the categories the same.
Used
Cracked Vinyl
Snail Trail
Blemished
Scratched
The blemished seem to have the lowest output maybe?
The cracked vinyl may have the shortest future life once they fully crack and get water inside?
The snail trails tested by Will seem to output good power in-spite of the ugly looks
The used and the scratched (I would appreciate clarification of these categories)
Have I got the correct understanding? Which ones are the safest to buy?
Now the brands (used panels mostly come with no warranty - Only 1 year SanTan warranty)
Trina (Chinese)
Canadian Solar (Tier 1 Solar with Canadian roots - Chinese manufacturing)
Yingli (Chinese)
RenSola (Chinese
SanTan (rebranded to SanTan from other brands - off grid use only)
BenQ (Tier 1 Solar with Taiwanese roots - offshoot of Acer)
Hyundai (Korean)
Jinko (Chinese)
Hanwha / QCells (Korean)
Kyocera (out of the solar business in the Americas)
REC (Singapore / Indian quality brand originally created in China upper tier)
Frontier (Japanese)
SSG(Chinese)
SunPower(Chinese)
SunTech(Chinese)
Longi(Chinese)
JA Solar(Chinese)
LG (Korean no longer in the solar business)
Feel free to correct my musings above, and rank these brands on the likelihood of failure
