Recorded verbatim from the source; no schema field exists for these yet.
| Enhanced Product Warranty on Materials and Workmanship* / Linear Power Performance Warranty* | The two warranty figures printed on this datasheet are 30 and 12 years, but the printed layout does not let the label-to-number mapping be read unambiguously from the fetched text (two reads returned product=30/performance=12, which is the reverse of Canadian Solar's usual 12/30 convention and of the badges on the csisolar.com product page). |
| Front Glass / Back Glass | 2.0 mm / 2.0 mm heat strengthened glass |
| Power Bifaciality | 85 % |
| Subsequent annual power degradation | no more than 0.35% |
