Das Solar presents 22.4% efficient n-type TOPCon solar panels



Das Solar’s new tunnel oxide passivated contact (TOPCon) product, developed for large PV applications, offers 605 W to 625 W power. Its temperature coefficient is -0.30% per degree Celsius.

“The highest conversion efficiency of the modules is 22.72% at an output power of 635 W,” said a company spokesperson. pv magazine.

According to the product description, new DAS-DH156NA there are five versions of the panel with powers between 605 W and 625 W. The power conversion efficiency varies between 21.6% and 22.4%.

The breakdown voltage ranges from 55.18 V to 55.74 V and the short circuit current from 13.95 A to 14.27 A. Each module measures 2465 mm x 1134 mm x 35 mm and weighs 35.0 kg.

The panels have a junction box with IP 68 classification and a frame made of anodized aluminum alloy. Both sides of the modules are covered with 2 mm glass. Their operating temperature is between -40 C and 85 C and the temperature coefficient is -0.30% per degree Celsius.

The panels can be used in photovoltaic systems with a maximum voltage of 1500 V. DAS Solar offers a 30-year power guarantee for 87.4% of the original output and a 15-year product guarantee. It claims a bifaciality factor of up to 80%, with power gains ranging from 10% to 30%.

“The module has passed several certifications, three times the basic test IEC 61215 and IEC 61730 of threshing test, ammonia and salt spray corrosion tests IEC 62716 and IEC 61701, PID testing IEC 62804-1, dust and sand tests,” said. spokesman.
