| Monocrystalline panel | Lower efficiency and higher temperature coefficient, but lower cost and better performance in low-light conditions |
|---|---|
| Mono PERC panel | Lower power output and efficiency, but more cost-effective for budget systems with less space constraint |
| Buying panels from multiple suppliers | Consistent performance and warranty across a batch, with no mismatch losses in string |
| Low-grade polycrystalline panels | A-grade cells ensure higher output and longer lifespan, with no early degradation |

Positive Power Tolerance (0~5W) Guaranteed High module conversion efficiency (up to 20.9%) Slower power degrad

View product →The panels range from 260W to 295W, with specific models at 260W, 265W, 270W, 275W, 280W, 285W, 290W, and 295W.
This product is polycrystalline. Monocrystalline panels are available separately under different model numbers.
It is not recommended. Mixing models with different Voc or Imp values can cause mismatch losses and reduce system efficiency.
They are packed on pallets with 30 units per pallet for 60-cell and 27 for 72-cell, wrapped in protective film and corner guards.
60-cell panels fit 400 in a 20GP, 840 in a 40GP, and 924 in a 40HC. 72-cell panels fit 270 in a 20GP, 648 in a 40GP, and 696 in a 40HC.
