Do 650 W and 700 W Solar Panels Go on House Roofs?
Summary
Not in the residential lines. The largest panels sold for homes are still in the 400s. Qcells' North American site lists its residential modules at up to 440 W, with 645 W and 680 W models in the commercial and utility sections. Trina's Vertex N (TSM-NEG21C.20), which runs to 725 W, sits in Trina's utility module list and measures 2,384 × 1,303 mm at 38.3 kg.
Four panels side by side
Two residential modules next to a 650 W and a 725 W model, using the top class from each datasheet:
| Qcells Q.TRON BLK M-G2+ | REC Alpha Pure-RX | JinkoSolar Tiger Neo (78HL4-BDV) | Trina Vertex N (NEG21C.20) | |
|---|---|---|---|---|
| Max power | 440 W | 470 W | 650 W | 725 W |
| Size | 1,722 × 1,134 mm | 1,728 × 1,205 mm | 2,465 × 1,134 mm | 2,384 × 1,303 mm |
| Area | about 1.95 m² | 2.08 m² | about 2.80 m² | about 3.11 m² |
| Weight | 21.2 kg | 22.7 kg | 34.0 kg | 38.3 kg |
| Efficiency | 22.5% | 22.6% | 23.25% | 23.3% |
| Current at max power | 13.20 A | 8.49 A | 13.45 A | 17.47 A |
| Max system voltage | 1,000 V | 1,000 V | 1,500 V (IEC) | 1,500 V |
Efficiency differs by less than one point, and every module delivers 225 to 233 W per square meter. The 725 W panel makes 1.65 times the power of the 440 W one from about 1.6 times the area, and at 38.3 kg it weighs close to twice as much.
Current does not follow wattage. The 470 W REC runs at 8.49 A, below the 13 A of the Qcells and Jinko panels, while the Trina reaches 17.47 A. Qcells names "rooftop arrays on residential buildings" as the intended use; Trina's product page aims the Vertex N at utility-scale projects. The REC and Jinko datasheets state no intended use, and the Jinko sheet is dated 2024.
