Product details
| Parameter | Typical / Expected Values |
|---|---|
| Rated power (Pmax) | ~ 450 Watts |
| Voltage at max power (Vmp) | ~ 40-50 Volts (often closer to ~45-48 V for “48V system” panels) |
| Current at max power (Imp) | ~ 9-12 Amps (depending on Vmp) |
| Open circuit voltage (Voc) | ~ 55-60 Volts |
| Short circuit current (Isc) | ~ 10-13 Amps |
| Efficiency | ~ 20-22% (maybe slightly higher or lower depending on quality) |
| Cell type | Monocrystalline. Possibly PERC or half-cell design for better performance. |
| Number of cells | Could be ~ 120 cells (often in a 6×20 layout, or variants thereof), or sometimes around that arrangement. |
| Dimensions | Large panel: roughly 2 m × 1 m area (exact size depends) and thickness around 30-40 mm with the frame etc. |
| Weight | In the range of 20-30 kg depending on build, glass thickness, frame, etc. |
| Frame and glass | Tempered glass with anti-reflective coating; aluminum frame, corrosion-resistant; junction box sealed, possibly IP rating (e.g. IP65 or IP68) |
| Connectors | MC4 or compatible, with bypass diodes to reduce shading loss. |
| Warranty | Often ~ 25 years performance warranty, and a shorter product / materials warranty (10 years or so) |
