Lithuania-based Solitek has announced two new 435W modules for integrated PV roofs with 22.04% efficient cell technology. Solitek’s Solid Solrif in-roof product line is combined with mounting systems supplied by Switzerland-based Ernst Schweizer AG.
Solitek, a Lithuanian manufacturer of modules and batteries, has announced two new in-roof tunnel oxide passivated contact modules (TOPCon) with a power of 435 W and a cell efficiency of 22.04%. The Solid Solrif D and Solid Solrif N panels measure 1767 mm x 1160 mm and are available in a completely black or transparent version.
“We have upgraded our entire module portfolio with new power outputs and advanced cell technology. Our modules are now among the most efficient on the market,” said Julius Sakalauskas, CEO of Solitek pv magazine. “This system serves as both a stylish roof and a powerful solar panel, debunking the myth that integrated solar roofs are too expensive.”
The modules are based on 108 half-cut M10 n-type TOPCon cells in a glass-glass package. The Solid Solrif D has 3.2 mm glass and hail class 4. The Solid Solrif N has 2.0 mm glass with hail class 3 certification. Both products feature an anti-reflective coating and a power temperature coefficient of -0.30%/C. The aluminum frame has a black powder coating.
The modules are made to serve as traditional tile roofing, made possible by an in-roof solution provided by Ernst Schweizer AG, a Swiss manufacturer of solar roof systems.
The modules are sold with a 30-year product and efficiency warranty and feature extreme weather capabilities, including support for snow loads up to 10,500 P, wind loads up to 3,600 P and fire class A certification. They have an open-circuit voltage of 38.92 V, a short-circuit current of 13.80 A and an IP68 rated junction box.
According to the manufacturer, all new Solitek modules retain the same sustainability features as previous versions, such as cradle-to-cradle gold certification. They are manufactured using 100% renewable energy, are 98% recyclable and contain 35% recycled glass.
