Product type
PV solar modules, or photovoltaic solar panels, are devices that convert sunlight into electricity using semiconductor materials. Typically composed of silicon, these modules harness solar energy through photovoltaic cells, which generate direct current (DC) electricity when exposed to sunlight. This electricity can then be converted into alternating current (AC) for use in homes and businesses or stored in batteries for later use.
| Material | Monocrystalline, polycrystalline, or thin-film silicon |
| Efficiency range | 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 period | 10 to 25 years |
When choosing PV solar modules, consider the efficiency rating, as higher efficiency can lead to more energy production in limited space. It's also important to specify the desired power output and dimensions based on your installation needs. Additionally, inquire about the warranty period and any certifications, such as IEC or UL, to ensure quality and reliability. Quantity requirements should be clearly stated to obtain accurate quotes.
