Up to 25% more energy from the same installation area

NEOSUN Duo is designed to bring you better ROI under the same installation area. Under any irradiation conditions, the bifacial Half-Cut PERC module will have a higher energy yield than any other module. With uncompromised energy gain, Duo generates up to 25% more power, reduce the installation area, and delivering the best LCOE possible. Advanced 9BB Half-Cut cells with PERC technology provide efficiency up to 23.2% (up to 21.5% module efficiency).

Combined with its less than 0.5% annual power degradation, higher energy yield, and 30-year power warranty, NEOSUN™ Duo lets you recoup your ROI much faster resulting in more long-term energy and savings than ever.

Half is the New Full

The laser separation of cells into two separate parts reduces resistance, increases productivity and durability of the element which together allows increasing the module efficiency up to new industry-standard 23.2%

Solar panels by NEOSUN Energy comply with international standards such as IEC, CE etc.


Enhanced 30 mm module frame and double iron-free 2 mm tempered glass allow withstanding snow load up to 5400 Pa, wind load up to 2400 Pa.

Lower Shading Loss

Due to the unique parallel connection system and operating voltage up to 1500V NEOSUN Duo modules continue to generate energy in low light conditions at sunset, dawn, or on cloudy days.

Our technology and production lines

Quality focus starts from product inception. The engineering team places a major emphasis on both process and equipment capabilities. We tightly control quality over every step of the manufacturing process, from silicon crystallization to module deployment in the field. Every material going into the product is heavily tested during the manufacturing process to ensure the highest quality standard and level of reliability.
