Solar panels are a key component of a solar system as they are responsible for converting sunlight into electricity. But what exactly are solar panels made of? Let’s take a closer look at the different parts of a solar panel and their functions.

Aluminum frames

Aluminum frames serve as structural supports for solar panels, providing durability and stability. It also helps protect the panels from environmental factors such as wind, rain, snow, etc. Additionally, the frame makes it easy to mount solar panels to a roof or solar mounting system.

 Tempered glass

The glass on the front of a solar panel acts as a protective layer, protecting the solar cells from external factors while still allowing sunlight to pass through. The glass must be durable and transparent to ensure maximum sunlight exposure and efficient energy conversion.

 Encapsulants

Inside a solar panel, encapsulating materials,e.g. EVA film, are used to bond the solar cells together and protect them from moisture and other environmental factors. Sealants also help improve the overall performance and longevity of solar panels.

 Solar Cells

The most important part of a solar panel is the solar cell, which is responsible for converting sunlight into electricity through the photovoltaic effect. These cells are typically made of silicon and arranged in a grid pattern to maximize the efficiency of capturing sunlight.

 Backsheets

The backsheet of a solar panel acts as another protective layer, shielding the solar cells from the back and providing insulation and electrical protection. This component helps maintain the integrity and performance of solar panels over the long term.

Junction boxes

Finally, junction boxes are responsible for connecting solar panels to other panels in the solar array and to the building’s electrical system. It also contains the wiring and electrical components needed for the safe and efficient operation of solar panels.
