TW Solar TWMNH-66HD620 Bifacial Solar Panel, 620 W

Description

TW Solar has launched a brand-new series TWMNH  photovoltaic modules and introduced cell technology N-Type. A new series of bifacial solar panels, primarily designed for rooftop solar power plants.

Monocrystalline bifacial solar panel TWMNH-66HD620 Bifacial It is used in grid-connected, hybrid, or off-grid solar power plant systems. It has a power output of 620 W, which is very high target for 2025. The solar panel’s efficiency is very high at 23.00 % when paired with an inverter, allowing it to be used effectively to generate revenue under the «green tariff» program or for off-grid power supply.

The model was built using the best materials and components available on the photovoltaic market. 132 high-quality silicon cells They are mounted in a 30-mm-thick composite alloy frame, arranged in 22 rows. By converting solar energy into direct current with a maximum voltage of 41.55 V and a current of 14.93 A, they generate minimal heat, thereby increasing the efficiency of each cell. The panel’s surface is securely protected on both sides by 2-millimeter-thick tempered glass.

The solar panel withstood a hailstorm with 25-mm hailstones and wind speeds of 23 m/s. The structure is capable of withstanding snow loads of up to 5,200 Pa and wind loads of up to 2,400 Pa. It is resistant to salt spray, ammonia, and dust, as confirmed by independent testing. The panel’s surface is reliably protected by a double layer of 2.0 + 2.0 millimeter tempered glass.

The device's IP68 protection rating means that it is completely protected against dust ingress and can withstand brief immersion in water to a depth of up to 1 meter. Accidental contact between the electrical components and a person is prevented.

The device has larger dimensions of 2382 × 1134 × 30 mm and weighs only 32.5 kg.

The manufacturer provides a 12-year warranty on the parts and components of the photovoltaic module. The warranty period for maintaining linear output performance is 25 years, and at the end of this period, the panel’s power output will be no less than 89.41 TP3T. That is, The panel's degradation over 25 years of operation is only 10.6%.
