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

6 New monitoring system

7 Communication with data-logger – internet: Beck IPC A few technical details: Chip socket Housing Operation power consumption Interfaces Inputs/Outputs Input voltage Output voltage Special functions Connectors DIL32 (SC12) Plastic housing 15-30VDC, 2,2W 2xCOM/TTL, 10BaseT 8 bidirectional I/O pins 15-30VDC, 10 kHz, LED’s 15-30VDC/100mA, 10 kHz, LED’s I²C bus, timer output screw terminal, RJ-connectors

8 New monitoring system

9 New monitoring system AC energy (W) Voltage DC (V) Current DC (A) Irradiaton (W/m²)

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

11 2. Self-made collector Pedro Ligneel Catholic Institute of Higher Education in South – West- Flanders Belgium

12 Self-made collector Italy m² since 1995 co-operative (Verband Alternatieve Energie VAE) 2 collectors /Man/day Belgium: start in m² in half year

13 Self-made collector

14 Construction of the flat plate solar collector Catholic Institute of Higher Education in South – West- Flanders Belgium

15 VAE-K16 DIN 4757 Deem 4 (ISFH) Hannover ISO ITC 180 SC5, ITR Rapperswil

16 Self-made collector Absorber –Cu 0,2 mm –710 *1910 mm (= 2*360 with overlap)

23 Frame = wood Insulation = 6 cm MW

24 Self-made collector Glass = 4 mm

25 Self-made collector

26 Solar Lack: Solarlack M40 Li Cost: –200 euro / collector –1 day work

27 Self-made collector Evaluation Catholic Institute of Higher Education in South – West- Flanders Belgium

28 Self-made collector Goal: online evaluation Measurements: –Ambient temperature –T collector (in) –T collector (out) –T Boiler –Pump on/off Online (internet) Visualisation With little energy

29 Self-made collector System: –16 solar panels (=22 m²) for a floor heating system and hot water production –Location: Torhout –Boiler 1000 liter

30 New monitoring system

31 Self-made collector How ? –IPC: chip with Ethernet and serial communication (energy consumption 3 Watt) –Connection with internet –Storage on server (no data logger) Extra: –Controlling pump –Adjusting delta T –Logging working hours –Synchronisation with time server

32 Info: –Pedro Ligneel KATHO –Luc Dedeyne BENERGIE
