Cloud coverage and cloud categorization may be analyzed for PV evaluation applications using the optional Find Clouds program. Two ASI-16 cameras with the accompanying Cloud Base Height (CBH) software can be used to measure cloud base height. The CBH program enables real-time cloud height assessment. To handle time-synchronized pictures from two sky imagers and local data, a stereoscopic approach is used (latitude, longitude, and elevation).
Its camera hardware features a robust coated quartz glass dome, 180°/360° fisheye optics, about 4-Megapixle resolution sensor with superb image quality, and an IR-cut filter avoid degradation of the sensor by long time direct exposure to the sun disk.
The ASI imaging software presents life stream videos via a user friendly web GUI, captures prescheduled all sky JPG pictures, and automatically transfers those JPGs to a network file storage via standard protocols (TCP/IP, FTP, File Share, HTTP). In case of network or network file storage down, the imager will temporarily backup JPG’s on the built-in 4 GB CF memory, and will restart transfers as soon as the network is up again.
The ASI-16/50 comes with built-in ventilation and up to 60W airflow heating, to minimize condensation on the glass dome and to quickly remove eventual raindrops and snow. The system has been tested for harsh environments from -40°C up to more than +50°C air temperature. Its double-cover design combined with its forced ventilation will minimize the risk of damages because of long time exposures to very strong direct sun radiation.
The ASI-16’s basic model lacks an integrated ventilation and warming system.
