NOVELTY - Photovoltaic system (100) comprises: (a) a first (102) and a second (104) photovoltaic module group; (b) a wire-based hanging wire-way (106); (c) a first bundle of electrical cables (108); and (d) a power distribution network (110).    USE - The photovoltaic system is useful for photovoltaic modules or module groups.    ADVANTAGE - The photovoltaic system may be easier and more cost-effective to install by using a wire-based hanging wire-way.    DETAILED DESCRIPTION - A photovoltaic system (100) comprises: (a) a first (102) and a second (104) photovoltaic module group; (b) a wire-based hanging wire-way (106) coupled with the first and the second photovoltaic module groups; (c) a first bundle of electrical cables (108) supported by the wire-based hanging wire-way, one or more electrical cables from the first bundle coupled to the first photovoltaic module group; and (d) a power distribution network (110) adapted to receive a second bundle of electrical cables, the second bundle of electrical cables comprising the first bundle of electrical cables, and one or more electrical cables from the second bundle coupled to the second photovoltaic module group. INDEPENDENT CLAIMS are included for:    (1) a method for supporting a bundle of electrical cables between photovoltaic modules or module groups comprising: (a) coupling, to form a bundle of electrical cables, one or more electrical cables to a first photovoltaic module group; (b) coupling a wire-based hanging wire-way with the first photovoltaic module group and with a second photovoltaic module group; and (c) suspending the bundle of electrical cables between the first and second photovoltaic module groups by coupling the bundle of electrical cables to the wire-based hanging wire-way; and    (2) a method for supporting a bundle of electrical cables between photovoltaic modules or module groups comprising: (a) coupling, to form a bundle of electrical cables, one or more electrical cables to a first photovoltaic module group; (b) coupling the bundle of electrical cables to a wire-based hanging wire-way; and (c) suspending the bundle of electrical cables between the first photovoltaic module group and a second photovoltaic module group by coupling the wire-based hanging wire-way with the first and second photovoltaic module groups.
