TW Solar TWMNH-66HD615 is a 615 Wp N-type TOPCon bifacial solar panel for rooftops and larger arrays in Bangladesh. Tongwei lists this bin at 22.8% STC efficiency. SOLAR24 lists the sale price at ৳12,915 and the regular price at ৳18,450. Contact SOLAR24 for the current stock.
At STC, Voc is 48.90 V, Isc is 16.00 A, Vmp is 40.65 V and Imp is 15.13 A. Power tolerance is 0 to +3%. Power measurement tolerance is ±3%.
The datasheet calls this an N-type half-cell bifacial module. Cell orientation is 132 [6×22]. Bifaciality is 80% ± 5%. The rear-side examples for this bin are 645 W at 5%, 707 W at 15%, 768 W at 25%. Those figures are not the 615 Wp nameplate. Real rear energy depends on height, tilt, spacing and the colour of the ground.
Dimensions are 2382 ± 2 × 1134 ± 2 × 30 mm. Datasheet weight is 32.5 kg. The product card and this datasheet both print 32.5 kg. Front glass: 2.0 mm AR coating semi-tempered glass. Rear glass: 2.0 mm semi-tempered glass. The frame is anodized aluminium alloy. The junction box is IP68 with 3 diodes.
The Pmax coefficient is −0.28%/°C, Voc is −0.24%/°C and Isc is +0.046%/°C. Operating range is −40°C to +85°C. A hot roof produces less than the 615 Wp nameplate. Load: 5,400 Pa front / 2,400 Pa rear.
String design uses Voc 48.90 V at the lowest expected temperature, the inverter MPPT window, the maximum DC voltage and Isc 16.00 A. The maximum series fuse rating is 30 A. Maximum system voltage is 1500 V DC. This page does not give one string count for every inverter.
100% original and official products from us, backed by a guarantee.
Tongwei product warranty: 12 years
Tongwei performance warranty: 30 years
The 12-year term is materials and workmanship. The 30-year term is linear power, not 30 years of full panel replacement. The datasheet states 1% in the first year, then 0.4% per year. The chart prints 99.00%, 89.40% and 87.40%.
After you buy 15 modules from SOLAR24, warranty service for those modules is handled through SOLAR24. Keep the invoice.

The sheet lists ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, ISO 50001:2018, IEC 61215 / IEC 61730, IEC TS 62804, IEC 61701, IEC 62716 and IEC 60068-2-68. Not every certificate applies in every market at the same time.
TWMNH-66HD615 is the smaller frame with a 30 A fuse. TWMNF-66HD720 and TWMNF-66HD735 are the larger frame with a 35 A fuse. The 720 Wp and 735 Wp rows come from two datasheet issues, so the weight and glass lines are not the same.

The matching datasheet row is 615 Wp at STC: 1000 W/m², 25°C cell temperature, AM1.5.
STC module efficiency is 22.8%.
Yes. Bifaciality on this sheet is 80% ± 5%. Rear-side examples for this bin are 645 W at 5%, 707 W at 15%, 768 W at 25%. Those examples are not the 615 Wp nameplate.
Yes. The datasheet describes an N-type half-cell bifacial module. It is not a P-type PERC panel.
The datasheet lists 2382 ± 2 × 1134 ± 2 × 30 mm and 32.5 kg.
STC Voc is 48.90 V and Isc is 16.00 A. Vmp is 40.65 V and Imp is 15.13 A.
Tongwei prints a 12-year material and workmanship warranty and a 30-year linear power warranty. First-year degradation is 1%, then 0.4% per year. The chart prints 99.00%, 89.40% and 87.40%.
After you buy 15 modules from SOLAR24, warranty service for those modules is handled through SOLAR24. Keep the invoice. Tongwei's published 12-year and 30-year terms are unchanged.
A SREDA module search link was supplied for this model. The product card also prints Listed by SREDA.
Use this row's Voc 48.90 V at the lowest expected temperature, and Isc 16.00 A. The series fuse rating is 30 A. Rear-gain wattages are examples, not the fuse current.
No. ৳12,915 is the panel price. Mounting, extra cable and installation are separate.
The Pmax temperature coefficient is −0.28%/°C, so a cell hotter than 25°C produces less than 615 Wp.
TWMNF-66HD735 is 735 Wp, 2384 ± 2 × 1303 ± 2 × 33 mm TWMNF-66HD720 is 720 Wp, 2384 ± 2 × 1303 ± 2 × 33 mm
100% original and official products from us, backed by a guarantee.
The cable is 4.0 mm². Length is +400 mm and −200 mm, or ±1,400 mm, and it can be customized. The junction box is IP68 with 3 diodes.
Confirm TWMNH-66HD615, 615 Wp, efficiency 22.8% and Voc 48.90 V. Do not copy another bin's current onto this panel.
