Patent number: 9735728Abstract: Provided are flexible photovoltaic modules having flexible module connectors that allow their connector bodies to move with respect to other parts of the modules in one or more directions. This flexibility may be used to align connector bodies during installation. Further, flexibility may help to overcome the thermal expansion differences of various modules and supporting structure components during operation. Flexible arms may be used to support connector bodies with respect to module sealing sheets to provide the necessary flexibility. Such modules may also include various touch safety features to keep conductive elements of the module connectors disconnected from the photovoltaic cells prior to installation of the module and during initial installation operations. Also provided are flexible photovoltaic assemblies, each including multiple modules electrically interconnected with each other and sealed at their interfaces.Type: GrantFiled: April 14, 2014Date of Patent: August 15, 2017Assignee: Beijing Apollo Ding Rong Solar Technology Co., Ltd.Inventors: Tanya Dhir, Steven Croft
