Jolywood: new bifacial solar panel suitable for harsh climatic conditions

The Chinese manufacturer has announced that its new Windproof module with a glass back sheet uses zinc, aluminium and magnesium surface alloy technology and a high-strength steel substrate. It features an energy conversion efficiency of up to 23.03%.

Chinese photovoltaic module manufacturer Jolywood has announced a new n-type solar module with double-sided TOPCon and a glass back sheet for harsh climatic conditions.

The Windproof module features a reinforced steel frame based on zinc, aluminium and magnesium surface alloy technology and a high-strength steel substrate, offering ‘exceptional strength, corrosion resistance and resistance to extreme temperatures’.

‘The frame is 50% stronger than traditional aluminium frames and provides excellent resistance to wind and snow loads,’ the manufacturer said in a statement.

The panel is available in five versions with power outputs ranging from 570 W to 595 W and energy conversion efficiencies between 22.07% and 23.03%.

The open-circuit voltage is between 51.17 V and 52.17 V, and the short-circuit current is between 13.76 A and 14.06 A.

The module measures 2,278 mm x 1,134 mm x 29 mm and weighs 28 kg. It is made of 2.0–3.2 mm thick tempered glass and has a junction box with IP 68 protection.

The new product can operate with a system voltage of 1,500 V and temperatures ranging from -40 °C to 85 °C. It has a temperature coefficient of -0.30 % per degree Celsius.

The manufacturer provides a 12-year warranty on the product and a 30-year warranty on 87.4% of the initial power output. ‘The module is crack-resistant, ensuring stable operation even in the most demanding conditions,’ explains the manufacturer. ‘The result is a 1.63% higher energy yield.’

Jolywood JW-HT144N-R0-595 SF
Solar panel with a power output of 595 Wp and an efficiency of 23%. Use of a transparent back sheet with high transparency in combination with TOPCon solar cells with high bifaciality.
The frame is designed as a special flexible cavity with 50% higher strength. The panel is more than 15% lighter than a bifacial double glass module. Low operating temperature, excellent heat dissipation, with an operating temperature 1.5℃ lower compared to bifacial double glass modules.
