  • Publication number: 20160211798
    Abstract: A photovoltaic module (10a) comprises an electrical connector of a first type (12) arranged so as to be able to cooperate with an electrical connector of a second type (13) of a first adjacent photovoltaic module (10b) to establish an electrical connection between the photovoltaic modules (10a, 10b).
