Photovoltaic glass, also known as solar glass or transparent solar panels, is a type of smart glass that uses embedded photovoltaic cells to convert sunlight into electricity to generate electricity.

Why do solar panels need a plexiglass cover?

This means it resists the sun's rays, which causes your solar panels to generate less electricity. This reduction in efficiency can be around 30%, depending on any gaps between your panels and the plexiglass. There are also many other features that a plexiglass cover offers, such as insect and debris proof protection from rain or snow.
