JinkoSolar and DuPont combine forces on new bifacial solar module ‘Swan’

Jinko-Swan

At the 2019 International Photovoltaic Power Generation Expo in Tokyo, DuPont Photovoltaic Solutions, together with JinkoSolar Holding Co, debuted the new Jinko high-efficiency bifacial module “Swan” protected by clear DuPont Tedlar PVF film-based backsheet.

The bifacial panel named Swan will be the latest addition to JinkoSolar’s Cheetah premium range. With a combination of high-efficiency Cheetah bifacial cells and clear DuPont Tedlar PVF film, Swan can achieve a high-power output of up to 400W in the front side and up to 20 percent energy gain from the rear side. Leveraging clear DuPont backsheet materials, Swan can produce the same power output level as dual-glass bifacial module with lighter weight, easier installation and 30 years power warranty.

How it works

The clear DuPont Tedlar PVF film is an ideal backsheet material for bifacial modules that can generate greater power output. Compared to a double glass module structure, the breathable, clear Tedlar PVF film based backsheets allow for higher reliability, lower operating temperature, up to 30 percent lighter weight, and a lower module installation cost. The clear Tedlar PVF film is expected to be a drop-in with most current manufacturing processes for backsheets and modules with little if any additional investment in equipment needed for most manufacturing processes.

With the iterative development of bifacial power generation technology, bifacial modules are gradually becoming one of the mainstream industrial applications. The clear backsheet materials can meet the requirements of light-transmittance, weather-resistance and ultraviolet-resistance for bifacial solar panels. The clear backsheet materials combine core advantages of light-weight, breathable, high gain and easy cleaning, which will further enhance the power output of bifacial modules, and ultimately help promote grid parity.

SunPower has launched its Next Generation Technology home solar panel called A-Series, delivering 400 and 415 watts of power. In Europe and Australia, homeowners can also now order a 400-watt solar panel from SunPower called Maxeon 3. Each is the first home solar panel to deliver more than 400 watts in its region and is designed to deliver 60 percent more energy in the same amount of roof space over the first 25 years compared to conventional solar.

“SunPower is introducing the world’s first 400-watt residential solar panels as most in the industry are just crossing the 300-watt threshold for home solar,” said Jeff Waters, CEO of the SunPower Technologies business unit. “Our record-breaking cell technology and innovative research and development efforts have enabled us to fit more power capacity on rooftops than we ever have before. Our growing panel portfolio is delivering unprecedented value across global markets that goes unmatched by any other residential solar technology currently available.”

A-Series panels are built with SunPower’s fifth-generation Maxeon solar cells, called Gen 5, which were perfected at the company’s Silicon Valley Research Facility. This breakthrough Next Generation Technology required new materials, tools and processes, and resulted in a 65 percent larger cell than previous generations that absorbs more sunlight and ultimately offers more savings to homeowners. The Maxeon solar cells are built on a solid copper foundation for high reliability and performance, and SunPower says these panels are virtually impervious to the corrosion and cracking that typically cause conventional panels to break down.

Combined with Maxeon Gen 5 solar cells is one of the industry’s highest-powered, factory-integrated microinverter, making A-Series ideal for use with SunPower’s Equinox platform.
