Novel BIPV material from South Korea
South Korean companies Posco
and East-West Power are developing a new
building-integrated solar photovoltaic solution. The new product uses
special galvanized
steel as the panel’s backside that Posco says lasts five to ten times
longer than standard steel.

South Korean energy
supplier East-West Power is partnering with Seoul-based steel maker
Posco on the development of a building exterior material that
integrates building-integrated photovoltaic (BIPV) panels.
Under the terms of the partnership, Posco will develop and construct
the BIPV materials while East-West Power will test the new products
under real conditions at several sites.
The BIPV panels used in the new building material would rely on PosMac,
a special steel manufactured by Posco, that is being used instead of
glass on the panels' backside. This innovation is expected to solve
the typical challenges of BIPV applications based on glass-glass
modules, creating a strong integration of the modules with a
building's structure.
“PosMAC features the highest corrosion resistance of all galvanized
steels in the world,” Posco claims. “The coating layer consisting of
three elements – magnesium, zinc and aluminum- delivers 5 to 10 times
higher corrosion resistance than regular galvanized steel.”
According to the manufacturer, PosMac is
particularly suitable for manufacturing electronics and automotive
uses, as well as for marine solar panels that are susceptible to
severe environmental conditions.
Posco said this new BIPV technology may also be used for applications
in agrivoltaics or rooftop PV, without providing further technical
details. “PosMAC has proven to be inevitable in building advanced
structures which is the backbone of generating sustainable solar
energy and bringing agricultural advancement,” the company said in a
statement issued in 2018.
