REC405TP5 Black 405Wp Solar Panel

The selling price is ৳9,800 per panel. The regular price is ৳12,000. SOLAR24 lists 25 panels in stock. Mounting, extra cable and installation are not included.

Rated STC power is 405 Wp in the REC TwinPeak 5 Black family. STC is 1000 W/m², 25°C cell temperature and AM 1.5. It is a laboratory rating, not a daily energy promise.

STC module efficiency for this bin is 20.6%. That is the share of standard-test irradiance converted by this watt class.

STC power is 405 Wp. NMOT power is 306 W, measured at 800 W/m², 20°C ambient, AM 1.5 and 1 m/s wind. NMOT is another test condition, not guaranteed field output.

At STC, Vmp is 38.0 V, Imp is 10.67 A, Voc is 45.1 V and Isc is 11.43 A. Vmp and Imp are the maximum-power point. Voc is open-circuit voltage. Isc is short-circuit current.

This 405 Wp module uses half-cut p-type cells in a full-black TwinPeak 5 module. The cell description in the reviewed datasheet is: 132 half-cut p-type monocrystalline cells, six strings of 22.

The reviewed datasheet lists 1899 × 1040 × 30 mm and 21.6 kg.

The reviewed document lists 1000 V. That is the array limit, not this panel's working voltage. This panel's STC Vmp is 38.0 V.

Maximum series fuse rating is 25 A. That is a protection rating, not the operating current. STC Imp for this bin is 10.67 A.

The reviewed Black Series datasheet states a 20-year product warranty and a 25-year power warranty: 98% in year 1, then 0.5% annual degradation, and 86% at year 25. REC ProTrust can extend cover when an REC Certified Solar Professional installs and registers the system. The performance warranty is retained-power cover, not a promise of full panel replacement for the whole term. The poster prints 20/25, which matches those two durations.

Yes. A search on 29 October 2026 returned REC405TP5 Black at 405 Wp on SREDA's Net Metering solar-module list. A listing for another REC wattage does not replace this row.

Use STC Voc 45.1 V for cold-weather string voltage and Imp 10.67 A for current. The string must stay inside the inverter limits and the 1000 V system rating. This page does not give one panel count for every site.

There is no single number. Divide the inverter's maximum input voltage by the cold-weather Voc of this 405 Wp bin, then check current against Imp 10.67 A and the 25 A series-fuse rating.

Confirm the label reads REC405TP5 Black, 405 Wp, and Voc 45.1 V. The SREDA row is for this exact name. Keep the invoice for the datasheet warranty, which is separate from the 20/25 line printed on the marketing image.

No. ৳9,800 is the panel price. Mounting, extra cable and installation are separate.

NMOT for this bin is 306 W, Vmp 35.5 V, Imp 8.62 A, Voc 42.2 V and Isc 9.23 A. Do not use the STC 405 Wp figure as the NMOT output.

Shade on part of a string reduces current in that string. This 405 Wp module has bypass diodes, but the datasheet does not promise full output under shade. Keep rows clear of vents, tanks and nearby walls where you can.
