Product details
| Parameter | Typical Value* | Notes |
|---|---|---|
| Maximum power (P<sub>mp</sub>) | ~ 390 W | Under STC (1000 W/m², 25 °C) |
| Voltage at max power (V<sub>mp</sub>) | ~ 30-40 V | Depends on cell configuration |
| Current at max power (I<sub>mp</sub>) | ~ 9-13 A | P = V × I |
| Open-circuit voltage (V<sub>oc</sub>) | ~ 35-50 V | Depends on temperature, design |
| Short-circuit current (I<sub>sc</sub>) | ~ 10-13 A | Depends on cell layout |
| Efficiency | ~ 18-22 % | Depends on cell quality, anti-reflection coatings |
These are indicative. The actual module may vary.
Mechanical & Physical Specifications
Dimensions: large panel — e.g. ~ 1.7 m × 1.0 m (or similar)
Weight: ~ 18-22 kg
Glass: tempered, anti-reflective
Frame: anodized aluminum alloy
Junction box protection: IP 67 / IP 68
Connectors: typically MC4-compatible
Load rating: able to withstand wind and snow loads (e.g. front-side ~ 5400 Pa, rear-side ~ 2400 Pa)
Operating temperature: from about –40 °C to +85 °C
Warranty: often ~ 10-12 years product warranty + 25 years output (e.g. 80 % of original) — similar to many manufacturers
Performance under Conditions
Temperature coefficient: e.g. –0.3 to –0.5 % per °C for power
Low light / diffuse light performance: monocrystalline excels relatively well under lower irradiance
Degradation: typical modules lose ~0.5 % to 1 % per year (varies)
Use & Application
Best used with an MPPT charge controller, especially if intended to support a 12 V battery system (though matching voltages may require adaptation).
Could be part of a larger panel array (series/parallel) to suit battery voltage (12 V, 24 V, or 48 V).
Suitable for residential, off-grid or hybrid solar systems.
