Product type
Rooftop solar modules are photovoltaic panels designed to convert sunlight into electricity. They are typically made from silicon-based materials, which are known for their efficiency in energy conversion. These modules are mounted on the rooftops of residential, commercial, and industrial buildings to harness solar energy, reducing reliance on traditional power sources and lowering energy costs.
| Material | Monocrystalline or polycrystalline silicon |
| Efficiency | 15% to 22% |
| Power output | 250W to 400W per module |
| Dimensions | Typically 1.6m x 1m x 0.04m |
| Temperature coefficient | -0.3% to -0.5% per °C |
| Warranty | 25 years for performance |
When choosing rooftop solar modules, consider the efficiency ratings and power output that best match your energy needs. Specify the type of material, such as monocrystalline or polycrystalline, as this affects both performance and cost. It's also important to inquire about warranties and certifications, such as IEC standards, to ensure product reliability. Provide details on installation requirements and the quantity needed for your project to receive accurate quotes.
