What are Solar Panels Made of?
Let’s Start with the Basics: The Solar Cell
The most critical part of any solar panel is what is known as the solar cell. Many solar cells make up a single solar panel, and these cells work together to convert sunlight into electricity through the photovoltaic (PV) effect. Most solar panels are made from crystalline silicon, meaning the cells are most often composed of thin layers of silicon, phosphorus, and boron. Silicon conducts electricity well, which makes it the perfect conductor for solar panels.
The Technical Stuff: The Solar Panel Protects Solar Cells
Once the cells are nestled together in the solar panel, the panel itself is sealed to protect the cells within and covered with non-reflective glass. This glass protects the solar cells from any damage, and its non-reflective quality allows sunlight to easily reach the cells. Once all materials are sealed, a metallic frame, typically made of aluminum, is fitted around the panel.
Monocrystalline vs Polycrystalline Silicon Solar Panels
There are two types of crystalline silicon panels you’ll find in the solar industry:
- Monocrystalline panels
- Polycrystalline panels
The biggest difference comes from the purity of the silicon. Monocrystalline silicon is made from a single crystal, and polycrystalline panels are made by melting the silicon fragments together. With monocrystalline panels, electrons have more freedom to move around, making them the more efficient of the two types of panels that convert sunlight into electricity more effectively.
What Type of Solar Panel Does SunPower Use?
SunPower is dedicated to producing and utilizing only the best, most efficient products within the solar industry. Because monocrystalline panels have the highest efficiency ratings available, SunPower uses monocrystalline panels. In addition, it is important to note that the efficiency of SunPower monocrystalline panels averages higher than most others—from 15% in most polycrystalline panels to nearly 23% with monocrystalline!
