Flexible solar panels (bendable up to 75 degrees) utilize advanced thin-film photovoltaic (PV) technology, enabling seamless integration into curved surfaces like rooftops, vehicles, or portable applications. These panels consist of lightweight polymer-based substrates coated with amorphous silicon (a-Si) or copper indium gallium selenide (CIGS) layers, which absorb photons from sunlight and generate direct current (DC) electricity.
Key Features:
- Adaptability: Unlike rigid glass-based panels, flexible modules conform to irregular surfaces (e.g., RVs, boats, or arched roofs), expanding installation possibilities.
- Efficiency: Modern flexible panels achieve 15–22% efficiency under optimal conditions, with reduced performance degradation in low-light or high-temperature environments.
- Durability: Encapsulated in weather-resistant polymers, they withstand UV exposure, moisture, and mechanical stress.
How It Works:
When sunlight strikes the panel, photons energize electrons in the semiconductor material, creating an electric field. This generates DC electricity, which flows through embedded conductive layers (e.g., silver or aluminum grids). For example, a 100W flexible panel can produce ~400Wh daily in moderate sunlight, sufficient to power small appliances.
Applications:
- Residential: Ideal for sloped, balcony or curved roofs common in European coastal homes.
- Commercial: Integrated into building facades or temporary structures.
- Off-grid: Used in camping gear or emergency power kits.
