What are Solar Panels made of?

Solar panels have become an increasingly popular choice for renewable energy generation. Harnessing the power of the sun, these incredible devices convert sunlight into usable electricity. If you've ever wondered what solar panels are made of and how they work, you've come to the right place. In this blog post, we will delve into the composition of solar panels, their functionality, and highlight GMI Electrical Ltd, a trusted MCS accredited installer based in South Wales, who can provide you with a competitive quotation for your solar panel needs.

What Are Solar Panels Made Of?

Solar panels, also known as photovoltaic (PV) panels, consist of several key components working in harmony to generate electricity. The primary material used in the construction of solar panels is silicon, a chemical element renowned for its semiconducting properties. Silicon is abundantly found in sand, making it an easily accessible and sustainable resource for the production of solar panels.

Here's a breakdown of the main components found within a typical solar panel:

  1. Solar Cells: Solar cells, also referred to as photovoltaic cells, are the heart of solar panels. They are responsible for converting sunlight into electricity. Solar cells are composed of silicon wafers, which are thinly sliced sheets of silicon that possess a particular electronic structure.

  2. Encapsulation Material: To protect the delicate solar cells from environmental factors like moisture and physical damage, they are encapsulated between a top layer called the front glass and a bottom layer known as the backsheet. The front glass is designed to be transparent, allowing sunlight to pass through, while the backsheet acts as an insulating layer.

  3. Frame and Enclosure: Solar panels are enclosed within a sturdy frame, typically made of aluminum, to provide structural support and protection. The frame also facilitates easy installation and mounting of the panels.

  4. Wiring and Junction Box: To collect and transmit the generated electricity, solar panels have electrical wiring attached to them. These wires are connected to a junction box, which serves as a central hub for interconnection and connection to an inverter or a battery storage system.
