The building Integrated Photovoltaics (BIPV for short) is to
provide power by fixing PV modules on the building envelop
enclosure surfaces and replace some conventional building
structures, such as roof sheets, tiles, windows,building facades
and rain shelters, as the functional parts of the building
structures. It can also be made as the PV multifunction building
modules to realize more function, such as thermo-PV device,
combination with lighting or solar shading and etc.
There are 2 ways to combine PV and building:
The first is the general combination form (general) which the PV
modules and systems are integrated with the building appearance or
The second is the combination form which the PV modules and system
are integrated with the building envelop enclosure and environment.
There are 3 installation forms:
1.Building material type: It refers to the indivisible building
structure or material which the solar battery is compounded with
the tile, brick, roll web, glass and other building materials, such
as the PV tile, PV brick, PV roof roll web, PV glass curtain wall,
PV sunroof and etc.
2.Integrated installation with roof and wall type: It refers to the
forms to install on the flat roof, overhead on the pitched roof and
parallel to the wall.
3.Structure type: It refers to the PV modules which are combined
with the building structures or become the independent building
structure, such as the awning part, shade structure and frieze
panel formed by the standard common PV modules or custom made as
the building requires.
Key BIPV issues:
(1) Grid PV power station design and construction which are
combined with landscaping and building;
(2) Power station's main equipments, such as PV modules, control
inverters and etc.;
(3) Grid control with the user-side low-voltage grid co-operation
and practical application in power stations;
(4) Optimization of PV array and building integration.
(5) Integrated design of solar PV power system and building;
(6) Installation structure, processing design, cable route design
and wiring, lightning protection, PV power station monitor system
and others of PV array on building roof.
BIPV applicable range:
Building curtain wall or external wall; building, awning of parking
area; building court; slant roof building's tiles; commercial
buildings; government office buildings; school buildings; hospital
buildings; airport halls, metro platforms; bus stops and
large-scale factory workshops.
