Germany’s AEG unveiled new all-black photo voltaic modules primarily based on n-type tunnel oxide passivated contact (TOPcon) expertise at Intersolar Europe this week in Munich, Germany.

“Their floor space is lower than 2 sq. meters, which makes them match for residential and business roof installations,” the producer stated. pv journal.

There are three variations of all black panels, with energy outputs of 420 W to 430 W and energy conversion effectivity rankings from 21.5% to 22.0%. The open-circuit voltage is between 38.17 V and 38.49 V, with a short-circuit present of 14.15 A to 14.25 A.

AEG additionally presents variations with silver or black frames and a white again sheet, with energy outputs as much as 435 W. The panels measure 1,722 mm x 1,134 mm x 30 mm and weigh which is 20.5 kg. They function 108 M10 half-cut monocrystalline TOPCon cells measuring 182 mm x 91 mm.

“AEG TOPCon modules have an distinctive low-light efficiency and on the similar time generate larger outputs at larger temperatures due to an improved temperature coefficient of lower than -0.30% per diploma Celsius,” stated AEG in an announcement. “Using PEO/EPE ensures sturdy chemical sturdiness of the laminate and permits it to resist the 2000 hour damp warmth take a look at.”

The brand new merchandise can function with a most system voltage of 1,500 V and have IP68 junction packing containers. They’ve an working temperature from -40 C to 85 C.

They’ve a 30-year linear energy output guarantee and a 15-year product guarantee. The degradation per yr is alleged to be lower than 0.4% and the 30-year finish energy output is assured to be at least 87.4% of the nominal output energy.
