Recommendations for sealing shattered solar panels

Hi,
I know very little about solar but just bought some 370w panels for very cheap that are new but have shattered glass. Very shattered. They still seem to work, though (tested Voc), and I'm going to use them to learn about creating a solar setup.
I am wondering what is the optimal product to seal them with. I've seen a lot of recommendations on YouTube and want to hear from the permies.
Thanks!

Hi Rachel
Well, if they still have full output, and you got them at a great price, then just about any pourable weather-proof sealant will work.
With your plan to use them as a temporary learning tool. I would buy the least expensive sealant and treat the panels gently.
Perhaps attach them to a wooden frame so they can not twist.
As long as nothing traumatic happens to them, they may just last many years.
However, I would not mix them with any new panels you might purchase in the future.
