A photovoltaic cell support assembly (10) comprises a first surface (32) provided with a plurality of recesses (14) configured to receive respective hooks (16) to facilitate hanging of the assembly (10) to a wall (18) to which the hooks (16) are attached. The assembly (10) is also provided with a second surface (13) configured to mechanically and electrically couple with one or more photovoltaic cells (24) and an electric circuit (22) supported by the assembly (10). The electrical circuit (22) is provided with a plurality of terminals (60) that extend through the second surface (13) to provide the mechanical and electrical coupling of the photovoltaic cells (24). The electric circuit (22) is configured to electrically connect the or each photovoltaic cell (24) coupled to the second surface together and to electrically connect the assembly (10) to a second like assembly (10).
