  1. Online evaluation PV and solar collector Pedro Ligneel Catholic Institute of Higher Education in South – West- Flanders Belgium

  2. 1. Monitoring PV system Pedro Ligneel Catholic Institute of Higher Education in South – West- Flanders Belgium

  3. PV system lab electricity • 9 *120 Wp = 1080 Wp • 30° • grid-connected • With data logger

  4. PV system lab electricity • Invertor Sunny boy (SMA) • Data logger: Heliograph (imec) • serial communication with PC • Memory (20 a 30 days) • Irradiance, DV voltage, DC current AC energy • Manually download of the data • Data = text file

  5. New monitoring system Requirements: • Automatic, no user intervention needed • Data = visual information • Public • No PC necessary • Low energy consumption • Back-up data
