DMEGC has unveiled its new monocrystalline PERC solar panels, which feature half-cell modules with power outputs ranging from 400 W to 410 W. The power conversion efficiencies for the four product versions range from 20.14 per cent to 21.2 per cent. These solar panels can be used with maximum system voltages of either 1,000 V or 1,500 V. Their short-circuit current is between 13.41 A and 13.77 A, while their open-circuit voltage is between 36.97 V and 37.45 V. The 54-cell M10 single-glass panels measure 1,708 mm x 1,134 mm x 30 mm and weigh 20 kg. They are made of tempered anti-reflective glass with a thickness of 2.8 mm and aluminium alloy frames. They also come with IP67 or IP68 enclosures. The solar panels have a temperature coefficient of -0.33 per cent per degree Celsius and an operational temperature ranging from -40 to 85 degrees Celsius.
The single-glass version of the panel comes with a 25-year linear power output guarantee and a 12-year product guarantee. According to reports, the first-year degradation is 2 per cent, and the end power output over the next 25 years is guaranteed to be at least 84.8 per cent of the nominal output power. The double-glass version has a 30-year power output guarantee and the end power output is guaranteed to be no less than 85 per cent.
