Photovoltaic Tracking System Solar Radiation Measurement: Data Validation Using MPPT

摘要

The operating mode of a common PV (Photovoltaic) generator envisages the installation of panels so that they must be oriented towards south direction and slanted according to a determined magnitude that varies depending upon latitude of chosen location. The value of the tilt angle of the PV panel is usually equals to the value of the latitude more or less 10°, according as one wants a great throughput of the PV facility during winter or summer time. In order to increase PV system throughput, different solar tracking plants have been implementing, that is, automatic systems capable of orienting panels (thanks to brightness and/or radiation sensors) so that solar rays must always be perpendicular to them. Consequently, a yield increasing can be noticed in terms of performances of the all PV plant. This research presents the outcomes of a tracking system, validated by means of a MPPT (Maximum Power Point Tracker) apparatus.
