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

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

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

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

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

New monitoring system
