Bonded Directly to Surface
· Lower installation costs.
· Resistant to theft.
Aesthetically Pleasing
· Uniform “black-tie”appearance.
· Dark interconnect wires.
Safer
· FLEX modules are lightweight-won’t
injure people or property in high wind
or earthquake.
· No cell degradation at high voltage.
· No grounding wires to corrode.
Requires Mounting Hardware
· Drives up installation costs.
· Subject to theft.
Clunky-looking
· Checkerboard appearance.
· Bulku paneling does not conform to
the roof.
Dangerous in environmental
emergencies
· Metal racks + box modules can
damage people and property in an
earthquake.
· Metal racks + box modules hazardous
in the event of wind pull-off.

CIGS Thin-film Modules vs. Polysilicon
Flexible
· Can fit around curved structures.
· Can be integrated into materials.
Durable
· Won’t break / Resistant to vandalism.
· No risk of microcracks to cells.
Lightweight
· No retrofitting required.
· Can be used in applications such as
consumer goods where weight is a
concern.
Rigid
· Not bendable.
· Requires racking to install.
Breakable
· Can shatter.
· Cells can develop microcracks.
Heavy
· Roofs require reinforcement to
support weight.
