Yes, solar panels can work through glass, but they won't be as effective as when they're set up outdoors. The decrease in efficiency is influenced by factors like the panel's quality, the amount of sunlight it receives, the thickness of the glass, and how clean the glass is. If you're thinking about installing solar panels indoors or behind a window, there are a few important technical and practical factors to understand before moving ahead. Glass is one of the key components of a photovoltaic (PV) panel, and the material is used for very specific reasons.
