9 Cell efficency relative to STC% Higher Yield in low Light Thin-film PV glass works down to 10% of sunlight delivering power even in low diffuse and ambient light conditions resulting in significantly higher yields than conventional crystalline silicon over the day and year a-si c-si Light Intensity W/m2

10 Superior Temperature Performance Thin-film PV Glass delivers consistent power at higher temperatures making it suitable for building integrated applications without the need for additional ventilation 110 Module Temp in UK Summer 100 P o w e r a-si c-si W Temperature o C

11 Shade Resistance Non position dependent Thin film module electrical construct reduces impact of partial shading Thin film modules high voltage enables parallel interconnected short strings Lower line losses Minimised impact from shading Negates need for microinverters
