The definition of the key factors of BIPV development.

Key factor	Definition
Insulation	Block thermal radiation heat from the sun and reduce indoor heat loads
Daylight penetration	Increase PV module light penetration and reduce interior lighting power demands
Artistic visual	PV fusion of the exterior of a building improves architectural aesthetics
Antistrong wind and rain	Resistant to strong wind and rain, thereby increasing building security
Antiearthquake	Resistant to earthquakes, thereby increasing building security
Fireproof	Resistant to fire, avoiding fire spreading from inside a building to adjacent buildings and avoiding external fires spreading inside
National technical building regulations	Must comply with national standards
Compliance with building rules	Must comply with construction technique rules
Compliance with construction material tests	Must comply with specifications for inspection and testing
