You tend to get what you pay for...
You need to be careful with knock off semiflexible panels as you never know what you get. The Chinese are most often buying the cells that don't pass inspection or are considered "A" grade. To the naked eye the product is a great look-a-like but under closer inspection you can see why they are not "performs-like"...
This is a severe level of microcracking of the cells on a brand new, just out of the box, Chinese knock-off panel... The polymers used in the Chinese panels are also not the same, so how long they will hold up to UV is another question mark? The inventor of these panels still has a patent on the technology, which the Chinese ignored.. Yep cheaper because they stole the technology (did not have to do the actual R&D), or tried to interpret it, but look-a-like is not always the same thing... Caveat emptor....
eMarine is a reputable company and I am surprised to see them selling these panels. They are all made by the same factory/company in China which has about 12 names, or "shells" they hide behind, and then those 12 +/- shells sell to about 40 different re-branders..
If eMarine is willing to stand behind the panel then it might be an okay deal if they push you off to the manufacturer good luck...
