Not to mention the non-glass patents with no U.L. Certifications going on 3 years now. What are the odds that those non-glass panels are even compatible with all of the new solar panel technology and applications (if ever certified)?
Solar panels need get to certified to be able to manufacture before the shelf life even starts.
in my humble opinion
