Device for monitoring photovoltaic system that is utilized for generating electric power from solar radiation, has data processing system connected with transmitter, where sensor or data providing device and meter are connected with system

摘要

The device has an energy meter (2) for determining electrical energy converted from a solar radiation using a photovoltaic system (1). A solar radiation sensor (3) or a weather data providing device and the meter are connected with a data processing system (4) for storage of values of solar radiation and weather data and determining efficiency or performance of the photovoltaic system from transformed energy and an operational parameter of the photovoltaic system and data of a model. The processing system is connected with a transmitter (5) for transmission of data to a central device (6).
