The Canadian Solar CS6.2-66TB-605 is a 605 Wp N-type TOPCon bifacial solar panel, made by CSI Solar. STC module efficiency is 22.4%.
At STC, Vmp is 40.6 V, Imp is 14.91 A, Voc is 47.8 V and Isc is 15.91 A. NMOT power is 458 W. NMOT is not the nameplate. Maximum system voltage is 1500 V and the maximum series fuse rating is 35 A.
The datasheet lists TOPCon cells in a 132-cell arrangement, written 2 × (11 × 6). Power bifaciality is 80% ± 5%, meaning rear Pmax divided by front Pmax at STC. The cover line “up to 85%” is the top of that tolerance. It is not a promise of 20% more electricity on a site.
The datasheet examples for this bin are 635 W at 5%, 666 W at 10% and 726 W at 20%. Real rear-side energy depends on mounting height, tilt, spacing, rear shading and ground albedo.
The module is 2382 × 1134 × 30 mm and weighs 32.8 kg. Front glass is 2.0 mm heat-strengthened glass with an anti-reflective coating. Rear glass is 2.0 mm heat-strengthened glass. The frame is anodized aluminium alloy, not the composite-frame variant. The junction box is IP68 with 3 bypass diodes. Connectors are T6 or MC4-EVO2A.
The Pmax coefficient is −0.29%/°C, Voc is −0.25%/°C and Isc is +0.045%/°C. Operating range is −40°C to +85°C. A hot cell produces less than the 605 Wp nameplate. The sheet states snow load up to 5400 Pa and wind load up to 2400 Pa, subject to the mounting conditions in the installation manual.
String design has to check Voc at the lowest expected temperature, the MPPT window, the inverter's maximum DC voltage, maximum PV input current and Isc of 15.91 A. This page does not give one string count for every inverter. The module suits commercial, industrial and ground-mounted arrays where the structure can carry 32.8 kg and a 2382 mm length.

The datasheet lists IEC 61215, IEC 61730, UL 61730 and other certificate lines. The same sheet says not every certificate applies in every market at the same time. ISO 9001, ISO 14001, ISO 45001 and IEC 62941 are management-system certificates, not a separate certificate of every module.

The sale price is ৳12,100 per panel. The regular price is ৳16,900. SOLAR24 lists 35 panels in stock. Mounting, extra cable and installation are not included.
STC maximum power is 605 Wp. STC is 1000 W/m², 25°C cell temperature and AM 1.5. NMOT power for this bin is 458 W, which is not the nameplate rating.
Yes. The V1.5 datasheet describes the CS6.2-66TB family as an N-type bifacial TOPCon module with glass on both sides. Rear-side energy still depends on the site.
Yes. The matching datasheet lists the cell type as TOPCon and the technology line as N-type bifacial TOPCon. Cell arrangement is 132 cells, written as 2 × (11 × 6).
STC module efficiency for this bin is 22.4%. The 23.3% figure on the datasheet cover is the top bin, CS6.2-66TB-630, not this 605 Wp model.
STC Vmp is 40.6 V. NMOT Vmp is 38.4 V. Use the STC and cold-weather Voc when designing a string, not the NMOT voltage alone.
STC Imp is 14.91 A. NMOT Imp is 11.92 A. The 35 A figure is the maximum series fuse rating, not the operating current.
STC Voc is 47.8 V. NMOT Voc is 45.3 V. Cold weather raises Voc above the STC value, so the string must be checked against the inverter's maximum DC voltage.
STC Isc is 15.91 A. NMOT Isc is 12.82 A. Inverter input current and fuse sizing must consider Isc, not only Imp.
The datasheet lists −40°C to +85°C. Nominal module operating temperature is 41 ± 3°C. A hot cell produces less than the 605 Wp STC nameplate.
The V1.5 sheet lists 2382 × 1134 × 30 mm and 32.8 kg for this family. The frame is anodized aluminium alloy. This is not the composite-frame variant.
The specification table states power bifaciality of 80% ± 5%. That is Pmax rear divided by Pmax front, both at STC. The cover line “up to 85%” matches the top of that tolerance. It is not a guaranteed increase in system output.
The datasheet prints example bifacial gains for this bin of 635 W at 5%, 666 W at 10% and 726 W at 20%. Those examples depend on mounting height, tilt, spacing, rear shading and ground albedo. They are not a promise that this 605 Wp panel will deliver 20% more electricity.
The datasheet calls the 12-year term an enhanced product warranty on materials and workmanship. It is separate from the 30-year linear power performance warranty. Claim handling follows the Canadian Solar limited warranty statement.
It is a linear power performance warranty, not 30 years of full panel replacement. The sheet states first-year power degradation of no more than 1%, then no more than 0.4% per year after that.
SREDA listing not verified. On 5 November 2026 a search for CS6.2-66TB-605 returned no row on the SREDA Net Metering solar-module list. A listing for another wattage in this series does not list this 605 Wp model.
This page does not name one inverter or one string length. A designer must check Voc at the lowest expected temperature, the MPPT window, maximum inverter DC voltage, maximum PV input current and Isc 15.91 A. The module's maximum system voltage is 1500 V and the maximum series fuse rating is 35 A.
The module is a 1500 V bifacial panel, 2382 × 1134 × 30 mm and 32.8 kg. It is used in commercial, industrial and ground-mounted arrays when the structure, wind and snow design, and inverter limits suit this size. It is not a small off-grid panel.
