1 Flexibility and Continuity
Flexible PV can be installed on light structure, in an overhead configuration, thus increasing roof effective area. Because of module colours, textures, film continuity and fluidity, there can be more design innovations and options for Architects.
2 Sensitive to Low Light Conditions
Still able to produce usable electricity under overcast/cloudy or rainy days. Energy output per watt is higher in tropical climate. Flexible solar module is less sensitive to Sun's position and therefore can be installed on any orientation and direction.
3 Less Temperature Sensitive
Flexible thin film technologies have lower power-temperature or some, positive power-temperature coefficient. The energy output fluctuates much less than conventional photovoltaic systems in hot weather. It is now possible to install very close to the hot surfaces, use less construction material and reduce on installation cost.
Easily installed on all types of surfaces, including building facades. Now every surface can generate electricity.
5 New Age Material
Flexible photovoltaic modules are laminated with high performance engineering thermoplastics. Specially treated UV-resistant laminates last indefinitely and can be re-cycled. Flexible solar modules have no glass component, therefore cannot splinter. Solar modules are safe, non-reflective and are easy to transport.
Flexible PV modules are of a newer technology and are manufactured in US, Europe and Japan. The quality is assured.
7 See Through Solar Rigid Panels
Enhance the aesthetics of buildings. See through solar panels can replace double-glaze glass window panels, and can generate electricity for use, especially on the east-west facing side of a building.
8 Environmentally Friendly
Flexible solar modules take less energy to produce, transport and install, therefore discharges much less carbon emissions to the environment.
1 Rigid Panel Frame
Fixed aluminium frame panel. There's a need to navigate away from M&E facilities, to find space for installation on roof. Panels sporadically arranged, pose an eye sore. No continuity in panel arrangement, functionality focus, makes the roof unsightly.
Rigid solar panel is heavy and requires elaborate supporting structures. Installing on older roofs poses a challenge in stump anchoring, which may affect waterproofing warranties.
3 One Directional Orientation of Panel
Needs to face the sun to optimize power generation, thus may not be suitable for all roof configuration.
Rigid solar systems are encapsulated by glass panels, which reflect sunlight. It causes glare to certain location consistently.
5 Longer Energy Pay Back
Rigid solar panel system uses much more energy to produce, transport and install a rigid panel.
