A rooflight assembly 10 comprising a solar cell 4, whereby the solar cell 4 has a smaller width and/or length than the overall assembly 10 such that at a window along at least one edge of the solar panel 4 is defined and allows natural light to pass through the assembly 10. The assembly 10 preferably comprises an upper translucent or transparent panel 20a which has a greater width and/or length than the solar panel 4. The assembly 10 and/or the solar panels 4 may be optimally angled to best receive incident light from the sun. The solar panel 4 may be of the form of a photovoltaic cell and may be coupled to a light intensity sensing element, a chargeable power supply and a wireless transmitting device, such that power can be supplied to any artificial lighting when the incident light drops below a set threshold. |
