Facility - Noria Software
To extract data from the ESTER database a management software called Noria has been expressly conceived. The software is highly flexible and for each configuration of the stands, it allows to visualize the PV modules arrangement . On the basis of the configurations under test, the database can be queried by a syntactic query builder and logical composer in order to extract I-V curves, PV module maximum current, voltage and temperature with respect to date and time, radiation intensity and environmental parameters.
The software consists of a “hardware repository” where all the instruments, converters and sensors of the PV test unit are listed. The configuration section allows to assign the environmental sensors to the specified channel of the data acquisition system and after the stands are properly configured they can be visualized on the computer screen. On the virtual stand is then possible to add the PV modules currently under test and to connect them with the corresponding MPPT.
PV modules information as well as stands configurations are stored in the database and used to extract environmental and modules parameters from the ESTER database.
Here you can see an example of the virtual stand and of the I-V curve presentation after the query. All the information can be exported in ASCII and/or Excel format files and also printed in a report.
