Flexible Solar Modules on a Curved Factory Roof: A Belgian Hybrid Rooftop Case A factory in Belgium was already generating from a rigid rooftop PV array mounted on ballasted tilt frames across the flat roof areas. What those areas did not cover was the barrel vault running down the centre of the building, a continuously curved surface with no plane to seat a frame on. The customer bought 20 LIONSHEE 240 W flexible modules for that vault, adding 4800 W - 4.8 kWp - of rated capacity without touching the rigid array already in service. This case looks at why a framed glass module cannot use a barrel vault, how the flexible row follows the curvature, and what the two module formats do side by side on one roof. No yield, savings, inverter, mounting or commissioning figures were available for this project and none are estimated.
