Photovoltaic modules for solar installation

摘要

The photovoltaic (PV) modules are alignable to the sun and includes several, separated support posts (8-10), each locating a PV module (3), rotatable about a vertical axis and aligned at a preset angle to the horizontal. For the simultaneous rotation of the PV modules is provided a circulating, driven element. The rotary mounting of the PV modules contains a gear wheel (7), while a circulating chain runs over the gear wheels. A drive gear wheel also engages the chain. A spring-loaded gear wheel may engage the chain for equalising thermal length expansion.
