Photovoltaic-module for use in e.g. pitched roof of house, has ventilator increasing air stream at lower side, and control system comparing initial temperature with reference temperature of module and for adjusting power of ventilator

摘要

The module (10) has a housing provided with a frame for enclosing the module. A holder is provided for distant mounting of the module on a house roof (2). A sensor is provided for detecting an initial-temperature of the module and/or a surrounding area. A rolling ventilator (1) e.g. tangential-ventilator, increases an air stream at a lower side of the module. A control system compares initial temperature with a reference-temperature of the module and for adjusting power of the ventilator. The ventilator is arranged below the module. Independent claims are also included for the following: (1) a supplement construction kit for the module (2) a method for cooling the module.
