A method for theft-prevention monitoring of individual solar modules (2a, 2b) in a solar installation (1) having a multiplicity of solar modules, wherein the solar installation (1) has an electronic monitoring unit (12a, 12b) which transmits status information, such as in particular the generated voltage and temperature of the modules, to a server (30) via a long-range data communication network (28), and generates a warning signal when a solar module (2a, 2b) is removed from the solar installation (1), is defined by the fact that a first monitoring unit (12a) is connected to a first solar module (2a), and a second monitoring unit (12b) is connected to a second solar module (2b) of the solar installation (1) in order to exchange data with one another via a further short-range data communication network (26), that the first monitoring unit (12a) on the first solar module (2a) has the function of a slave in the short-range data communication network (26), which slave transmits local status information to the second monitoring unit (12b) via the short-range data communication network, that the second monitoring unit (12b) performs the function of a master in the short-range data communication network (26), which master transmits the local status information of the first solar module (2a) and the local status information of the second solar module (2b) in cumulated form to the server (30) via the long-range data communication network (28), and that when the data exchange between the first monitoring unit (12a) and the second monitoring unit (12b) is interrupted, the first monitoring unit (12a) assumes the function of a master which transmits an alarm signal and/or status information to the server (30) via the long-range data communication network (28). The invention also relates to a solar installation (1) having a multiplicity of solar modules (2, 2a, 2b) for carrying out the method. |
