Product Parameters:
| Parameter | Definition/Description | Unit | Typical Value/Range | Impact/Notes |
| Short-circuit current (Isc) | Maximum output current when terminals are short-circuited | Ampere (A) | Increases with solar irradiance | Depends on cell area, irradiance, and material technology |
| Open-circuit voltage (Voc) | Voltage between terminals under no-load conditions | Volt (V) | Single cell: 0.5-0.7V; Modules: 30-35V (for 60-cell series) | Inversely related to temperature (↑ Temp → ↓ Voc) |
| Peak current (Imp) | Current at maximum power point | Ampere (A) | ~80-95% of Isc | Actual operating current, affected by irradiance and temperature |
| Peak voltage (Vmp) | Voltage at maximum power point | Volt (V) | Single cell: 0.45-0.5V; Modules vary by cell count | Must match inverter voltage range in system design |
| Peak power (Pmax) | Maximum output power (Pmax = Vmp × Imp) | Watt (W) | 100-400W (monocrystalline modules) | Measured under STC (1000W/m², 25°C, AM1.5 spectrum) |
| Fill factor (FF) | Ratio of maximum power to (Voc × Isc) | - | 0.5-0.8 (75-78% for high-efficiency modules) | Higher FF indicates output characteristics closer to the ideal rectangle |
| Conversion efficiency (η) | Percentage of sunlight energy converted into electricity | % | Monocrystalline: 15-24%; Polycrystalline: 12-18%; Thin-film: ~10% | Affected by material purity, temperature (↑ Temp → ↓ Efficiency) |
| Temperature coefficient | Rate of parameter variation per °C temperature change | %/°C | Pmax: -0.4% to -0.47%; Voc: -0.34% to -0.35%; Isc: +0.045% | High temperatures significantly reduce power output |
| Operating temperature | Allowable ambient temperature range | °C | -40°C to +85°C | Exceeding limits may cause performance degradation or damage |
| Maximum system voltage | Maximum allowable DC input voltage | Volt (V) | 600-1000V (varies by certification) | Critical for system safety when connecting to inverters/cables |
