Sunpower 300w foldable panels

Anyone have opinion about this 300w Sunpower panels? It was a listing on ebay(don’t know if I trust buying panels from ebay). It is missing specs I think important to know like VoC which also makes me suspicious. Anyone have experience with these panels?

I think this link shows it.
