If anyone tries it (with caution) please let us know. Seems like a scam to me.
An alternative for getting "cheap solar panels" is to buy quality USED solar panels. Just test them before you buy (voltage and current) and you should be good to go. On my RVs, I installed multiple 250w used panels that I got for $35 each and they are producing great. No moving parts on solar panels, so they should last for years and years. If you worry about max efficiency issues with these used panels, buy one extra and put it up and you'll have more solar than you originally intended (...assuming you have the space).
Good luck!
