This 300w foldable (the only one I've ever seen) is on Amazon for around $300 which seems like a steal. Most foldable panels are around 2 to $3 per watt. After looking at the companies other items they seem legit, but this panel has one Amazon review LOL. Considering buying it but I don't have the tools and know-how to run it through some tests to see if it's legit or not.
