The modules will be manufactured by the spin-off of Maxeon Solar Technologies and will use the interconnect of “tiles” instead of the traditional bus bars to connect the solar cells to each other.

The new double-sided solar panels will be marketed from the 4th quarter of 2020.

Maxeon Solar Technologies, a SunPower company, is committed to raising the bar in the photovoltaic industry. How? ‘Or’ What? The modules in question represent the latest chapter in the technology of “shingle interconnection“, A cell welding technique that replaces the more traditional“ bus bar ”technology.

The cells overlap slightly, like old wood shingles. In this way, the solder point necessary for the passage of current is created in the lower part of the panel.

This approach eliminates the need to interconnect the bands and the space between adjacent cells, preventing some parts from being obscured by bus bars.

It also leads to a reduction in resistance losses, which allows thinning of the fine silver threads called “fingers”And thus save on production costs.

Since a large part of the module can be covered by solar cells, it is a good technology for double-sided solar panels.

SunPower’s new line has been specifically designed to meet the needs of large multi-megawatt photovoltaic systems and, the company explains, is the first product to use single-sided and double-sided PERC solar cells made from large G12 wafers of eight inches.

The result, at least on paper, are modules with 21% efficiency, greater shade tolerance and longer life.

SunPower has over 30 years of innovation, including a history in the power plant segment – from the pioneering 10 megawatt Bavaria Solar One project in 2004 to the 349 megawatt Limondale Australia project in 2020. SunPower’s new Performance 5 range is accompanied by a renewed commitment to large-scale facilities, supported by a significant increase in the production capacity of cellular technology by our joint venture Huansheng Photovoltaic (HSPV) in China.
