SECURING SOLAR ENERGY COLLECTION DEVICES

摘要

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.
