Effect of Clouds on Solar Irradiance - Infrastructure

Cyprus University of Technology

The Sustainable Energy Laboratory (SEL), for the scope of this collaboration, is fully equipped with: a meteorological station (DNI, diffuse and global irradiance, humidity, temperature and wind speed/direction sensors), a BF-5 Sunshine Sensor and a hand held DNI sensor. Moreover, the optical equipment of the laboratory consists of an Orion all-sky camera, model StarShoot AllSky Camera II, a HERO wide angle lens camera and a NIKON D3100 DSLR camera.

Additionally, the Remote Sensing Laboratory (RSL) of CUT is a member of the ‘AERONET’ – NASA network and EARLINET and consists of the following resources: 8 GPS units with a reference station, 5 field spectro-radiometers (GER1500, ASD & SVC 1024), 2 sun-photometers Microtops II, 1 CEMEL sun-photometer, a RAYMETRICS backscatter/depolarization LIDAR System, solar irradiance meters, NDVI meter and smart meteorological stations.

The equipments usable in this project at the Renewable Energy Systems and Recycling Centre (RES-REC) consists of: 2 DeltaT meteorological weather stations (one having a SPN1 pyramometer for diffuse and global irradiance and the other having an ES2 energy meter; both of them can also measure humidity, temperature, wind speed/direction and quantity of rainfall), a precise Kipp&Zonen solar tracking system (type Solys 2, equipped with class A monitoring equipment: two CMP22 pyranometers, a CGR4 pyrgeometer and a CHP1 pyrheliometer), a portable pyranometer with datalogger, type LSI BSR153 and an indoor solar simulator, able to also simulate wind gusts.

The RES-REC centre has also a good software infrastructure (TRNSYS 17, METEONORM and own developed software) for solar energy radiation modelling.



During the project an all-sky camera will be installed at both sites to take images of the sky, which is a ground based camera able to capture pictures of the whole sky or part of the sky at scheduled time intervals.
