The item in the image is a solar panel, specifically a monocrystalline photovoltaic module.
Specifications
- Dimensions and Weight: Standard residential panels are roughly 1.7m x 1m and weigh between 18-32 kg.
- Cell Type and Count: Panels typically use monocrystalline or polycrystalline cells, with common counts being 60, 72, or 144 cells.
- Frame Material: Often made of aluminum.
- Electrical Specifications:
- Wattage (Pmax): The maximum power output, which can range from around 100W to over 500W depending on the panel.
- Module Efficiency: The percentage of light energy converted to electricity, with modern panels often exceeding 20% efficiency.
- Voltage and Current: Includes metrics like open-circuit voltage and short-circuit current.
- Power Tolerance: Defines the expected range of power output, often expressed as a positive tolerance (e.g., +5W).
- Performance and Durability:
- Temperature Coefficients: Crucial for performance in hot climates, indicating how much power output decreases as temperature increases.
- Certifications: Verify adherence to safety and performance standards like IEC 61215 and IEC 61730.
- Warranties: Typically range from 25 to 30 years for long-term investment.
