From stadiums in Brazil to a bank headquarters in Britain, architects led by Norman Foster are integrating solar cells into the skin of buildings, helping the market for the technology triple within two years. Sun-powered systems will top the stadia hosting 2014 FIFA World Cup football in Brazil. In Manchester, northern England, the Co-operative Group Ltd. office has cells from Solar Century Holdings Ltd. clad into its vertical surfaces.The projects mark an effort by designers to adopt building-integrated photovoltaics, or BIPV, where the power-generating features are planned from the start instead of tacked on as an afterthought. Foster and his customers are seeking to produce eye-catching works while meeting a European Union directive that new buildings should produce next to zero emissions after 2020.
“Building integrated solar in office buildings and factories which generate energy consistently during daylight hours, whilst not requiring additional expensive land space or unsightly installations, is seen as the most obvious energy solution,” said Gavin Rezos, principal of Viaticus Capital Ltd., an Australian corporate advisory company that’s one of the private equity funds putting money into the technology.
The market for solar laid onto buildings and into building materials is expected to grow to $7.5 billion by 2015 from about $2.1 billion, according to Accenture Plc, citing research from NanoMarkets. Sales of solar glass are expected to reach as much as $4.2 billion by 2015, with walls integrating solar cells at $830 million. About $1.5 billion is expected to be generated from solar tiles and shingles.
The technology provides a respite for solar manufacturers, opening the way for them to charge a premium for products. Traditional solar panel prices have fallen 90 percent since 2008 due to oversupply, cutting margins and pushing more than 30 companies including Q-Cells SE and a unit of Suntech Power Holdings Co. into bankruptcy.
