Abstract: Apparatus is provided for supporting a solar energy collection device (601, 602). The apparatus is substantially wedge-shaped with a base (102) for contacting a roof surface (203) and an inclined front face (103) for supporting the device (601). The apparatus is configured such that the total weight is adjustable so as to apply an appropriate loading on the roof. In a first embodiment ballast is supplied to a ballast cavity (105). In an alternative embodiment, wedge-shaped members (903) may be selectively removed from an assembly so as to provide a desired weight distribution.

Abstract: Apparatus is provided for securing solar energy collection devices to a roof. A plurality of rails (103, 104) are provided. Each rail is attachable to a roof (102) at mutually displaced positions and defines a rail slot (702, 915). Attachment devices (917) are provided, each configured to engage with a rail slot (702, 915) such that in a first condition the devices are free to move along the slot and in the second condition the devices are secured within the slot. The attachment devices (917) include an engaging portion (919) that protrudes from the slot to engage with a solar energy collection device.
