An apparatus for generating electricity from incident solar radiation, comprises: an enclosure for example, an inflatable envelope 10, 14, comprising at least one transparent section. A reflective surface 18 is contained within the enclosure adjacent the at least one transparent section and actuator for example an electric motor powered by a Miller Solar Engine, is contained within the enclosure and is connected to the reflective surface for adjusting the orientation of the reflective surface 18 relative to the enclosure about an axis. The reflective surface has a shape configured to focus reflected solar radiation onto a focal area and a photovoltaic cell 40 is positioned within the focal area. The apparatus may include solar trough 24. The enclosure may enable the aerodynamic profile of the apparatus to be improved. The reflective surface is mounted inside the enclosure, so the enclosure shields it from the wind and determines the aerodynamic profile. The orientation of the reflective surface relative to the enclosure can be changed to direct the reflective surface towards the sun without altering the aerodynamic profile. |
