Provided are novel building integrable photovoltaic (BIP) modules having flexible connectors and methods of fabricating thereof. According to various embodiments, a BIP module includes a photovoltaic insert having one or more photovoltaic cells and a flexible connector having a flexible member and a connector member. The flexible member provides flexible mechanical support to the connector member with respect to the insert. The flexible member may include a flat conductive strip, a portion of which is shaped to provide additional flexibility to the flexible member along its width. The connector member encloses one or more conductive elements, such as louvered sockets, which are electrically connected to the photovoltaic insert by the flexible member. In certain embodiments, the same flat conductive strip is used to form a shaped portion as well as conductive element and/or a portion of a bus bar extending into the photovoltaic insert.
