Core Electrical Performance
| Parameter | Typical Specs | Notes |
| Rated Power (Pmax) | 220W | STC: 1000W/m² irradiance, 25°C cell temp |
| Max Power Voltage (Vmp) | 18.0–21.6V | Matches 12V battery systems (220W/18V ≈ 12.2A) |
| Max Power Current (Imp) | 10.2–12.2A | Depends on Vmp and cell efficiency |
| Open Circuit Voltage (Voc) | 21.5–24.5V | For charge controller compatibility |
| Short Circuit Current (Isc) | 11.0–13.5A | Determines wire/connector sizing |
| Module Efficiency | 23–24.5% | Limited by module size and encapsulation |
Lightweight Mechanical Design
| Feature | Specs | Benefits |
| Glass Type | 1.6mm / 2.0mm chemically tempered glass | high transmittance (>94%) |
| Total Weight | 7–10kg (vs 12–15kg for traditional 220W panels) | Reduces rooftop load, easier single-person installation |
| Areal Weight | ~6–8kg/m² | Critical for low-load roofs, RVs, boats, and portable use |
| Frame | Lightweight aluminum (25–30mm) or frameless | Frameless models save weight for BIPV/flush mounting |
| Dimensions | ~1480×670×30mm (typical) | Fits compact spaces like RV roofs, small sheds, or caravans |
| Wind/Hail Resistance | 2400Pa wind / 5400Pa hail | Built for harsh outdoor conditions |

Key Application Scenarios
- Off-grid & portable systems: RVs, boats, camping trailers, and remote monitoring
- Low-load rooftops: Old buildings, sheds, or lightweight structures that can’t support heavy panels
- Marine use: Boats/yachts where weight and corrosion resistance are critical
- DIY projects: Small cabins, garden lighting, or backup power for homes
Design Advantages vs. Standard Panels
- 40–50% lighterfor easier handling and reduced structural stress
- Lower profile(30mm vs. 35–40mm) for sleeker installation
- High durabilitywith tempered glass, suitable for outdoor/rough environments
- Optimized for 12V systems(ideal for small off-grid applications)
