Ulica Solar bifacial glass-glass modules - for maximum yields and maximum stability


With bifacial cell technology and robust glass-glass construction, Ulica Solarcombines two proven performance factors in one module. The bifacial glass-glass modules utilize sunlight from both sides and thus enable up to 20 % additional rear-side yields, depending on the substrate. At the same time, the double layer of glass ensures optimum protection against environmental influences, UV radiation and moisture - a clear advantage for long-lasting ground-mounted and industrial roof systems.
The modules are available in various performance classes and, thanks to n-type TOPCon technology, offer excellent temperature resistance, low degradation and high efficiency - ideal for demanding applications with high energy yield and durability requirements.
