What Are Solar Roofing Shingles Made of?

Solar roofing shingles, also known as solar shingles or photovoltaic shingles, are innovative solar energy roofing solutions designed to resemble traditional roofing materials while harnessing solar power. These shingles are made of various layers, each serving a specific purpose in generating electricity from sunlight.

At the heart of solar roofing shingles are photovoltaic cells, which are responsible for converting sunlight into electricity. These cells are typically made of semiconductor materials, such as silicon, that have the ability to produce an electric current when exposed to sunlight. To protect the photovoltaic cells from environmental factors like moisture and debris, they are encapsulated in a durable and weather-resistant material. This encapsulation layer ensures the longevity and performance of the solar shingles.

The backsheet layer is a moisture-resistant backing that adds an extra level of protection to the solar shingle. It prevents water from infiltrating the shingle and ensures the integrity of the photovoltaic cells.

Some solar shingles have a glass or transparent coating on the front to protect the photovoltaic cells while still allowing sunlight to pass through. This layer ensures the efficiency of the cells and the longevity of the shingle. Most solar shingles are also interconnected using wiring and connectors that allow them to function as a unified solar array. The wiring transfers the electricity generated by each shingle to the overall solar energy system.

Some Denver solar shingle systems come with a frame and mounting system that helps secure them to the roof. The frame provides stability and allows for proper alignment and installation on the roof surface, so you don’t have to worry about long term stability.
