I've scoured the internet and found mostly discontinued product or stuff on websites for Chinese companies that I am reticent to consider in search of a good way to make a roof to a pergola made from clear bi-facial solar panels that also prevents water from coming through.  Does anyone have experience with this or know of a product or method that works?

This is a great and visually appealing way for a homeowner to install solar when maybe their roof isnt suited to it and can be tax advantaged as well.

Thanks in advance for any commentary.
