- To facilitate research in PV performance analysis, forecasting, and system design.
Main Methods
- Collected 5-minute inverter-level PV power data from 60 rooftop stations in Hong Kong (2021-2023).
- Gathered 1-minute on-site meteorological data using dedicated weather stations.
- Utilized the Brick schema for metadata representation to enhance data interoperability and analytics.
Main Results
- A comprehensive dataset covering three years of urban PV generation and weather data is now available.
- The dataset includes detailed site specifications, collection methodologies, data records, and validation information.
- Metadata is standardized using the Brick schema, enabling easier integration with smart building and energy analytics platforms.
Conclusions
- The released dataset is a valuable resource for advancing urban solar energy research and development.
- It supports diverse applications including PV benchmarking, degradation studies, fault detection, and forecasting.
- The open-source nature and standardized metadata promote wider adoption and innovation in the solar energy sector.
