Frameless solar panels can be stuck directly to rooftops
Singapore-based Maxeon Solar Technologies believes there is a way to install photovoltaic modules on the roofs of commercial buildings that may not support traditional structures. The company has developed frameless, thin and lightweight panels that can be glued directly onto a roof.
“The Maxeon Air technology platform continues our 35-year legacy of innovation in solar panel technology and demonstrates once again the ability of our research and development team to develop innovative, disruptive technologies,” said Jeff Waters, CEO of Maxeon.
“For nearly 50 years, the solar industry has used glass superstrate sheet constructions almost entirely. As solar cells have increased in size and the cost of solar cells has decreased dramatically, the cost of shipping, installing and assembling large sheets of glass has decreased dramatically Now, with Maxeon Air technology, we can develop products that reduce these costs while opening up entirely new market opportunities, such as low-load commercial roofs. “
Called a “peel-and-stick” solution, Maxeon Air panels have a built-in adhesive layer that allows them to be installed directly on the roofs of commercial buildings without the need for aluminum frames, shelves, anchors or ballast. They were also developed for uneven roof surfaces.
Each panel consists of a number of IBC solar cells that have a metal foundation and stress-free cell connections. It is reported that they are corrosion resistant and can bend without cracking. The panel’s overall efficiency is touted at 20.9 percent, and color tolerance has also been built into the design.
“Maxeon’s IBC module technology has the unique ability to conduct electricity in the shade and continue to generate electricity in conditions that other panels would shut down,” said Waters. “This feature, along with inherently low temperature sensitivity, provides industry-leading performance in all conditions.”
The company claims that the installed weight of around 6 kg / m2 is less than half the weight of conventional modules. Therefore, they are well suited for installation on roofs that are not designed for the weight of traditional solar systems. Maxeon estimates that the untapped potential of low-load commercial roofs could be over 4 GW in Europe alone. However, the company is also looking into potential use on the roofs of residential buildings, floating solar parks, and electromobility.
After five years of research and development, Maxeon Air technology will make its public debut in July, followed by the installation of a few select projects in Europe in the second half of this year. General availability is set for the first quarter of 2022.
