The Dutch start-up Solarge has developed a 500 W panel that is 50% lighter than traditional glass backplane modules. According to the manufacturer, this new product can be anchored to the roof using roof anchors, which eliminates the need for ballast.
Solarge BV, a module manufacturer based in the Netherlands, has developed a 72-cell monocrystalline solar module for photovoltaic systems deployed on flat roofs with limited load-bearing capacity.
According to the company, the Solarge DUO panels are based on M10 PERC batteries, which are 50% lighter than traditional glass back panels, and the roof load is only 6 kg/m2.
“The module configuration is a typical east-west configuration, with an inclination angle of 12 degrees, and can basically be installed on the roof in any desired direction,” CCO Huib Van der Heuvel told Photovoltaic Magazine. “The installation system is fixed on the roof by roof anchors, without ballast.”
The product has dimensions of 2,327 mm x 1,137 mm x 14 mm and a weight of 14.5 kg, which is 5.5 kg/m². It is characterized by a power output of 500 W, an open circuit voltage of 49 V, a short circuit current of 12.4 A, and a fill factor of 0.78%. Its temperature coefficient is -0.39%/degree Celsius, and the maximum system voltage is 1,000 V. The working environment temperature range is -40 to 85°C.
Solarge provides a 10-year product warranty and a 20-year power output guarantee. The annual linear degradation guarantee for 20 years is a maximum of 0.5%.
The manufacturer is currently producing these modules through a trial production line at its manufacturing plant in Eindhoven, the Netherlands. It is now completing the financing of a high-volume manufacturing plant, which is scheduled to open in the Netherlands in mid-2022. Commercial operations are planned to start in the second half of next year.
“In addition to being light, the sustainability performance of this innovative solar panel is also very good,” Van der Heuve said. “The carbon dioxide emissions of this product will be 80% lower than that of traditional solar panels, and the panels are completely circular in design and do not use perfluorinated and polyfluoroalkyl substances (PFAS) materials, which are comparable to all other solar panels. Solar panels that use polymer films instead of polymer films are different. Glass.”
