What is Thin-Film Solar?
Thin-film solar technology involves depositing thin layers of photovoltaic material onto a substrate, typically glass, metal, or plastic. This approach differs from traditional crystalline silicon solar panels, which use a thick layer of silicon to convert sunlight into electricity. Thin-film solar panels are lighter, more flexible, and often less expensive to produce, making them an attractive option for various applications.
