Annual Photovoltaic Performance Analysis Dataset
Purpose of the Dataset
This dataset aims to detail the hourly annual energy production of five photovoltaic self-consumption plants. It acts as a structured information source to facilitate technical monitoring, the analysis of real versus theoretical performance, and the optimization of maintenance and operation strategies based on historical operational data.
Scope and Technical Considerations
The dataset provides a granular and technical view of the energy assets' behavior under the following criteria:
- Temporal resolution: Hourly granularity (ISO 8601 format).
- Scope: Five monitored self-consumption plants.
- Update frequency: Monthly.
- Data origin: Technical telemetry from photovoltaic inverters and monitoring devices (loggers).
Type of Dataset
- Private dataset: Integrated into the EMPOWER-X sectoral data space (Gaia-X Lighthouse Project).
- Accessibility: Available to authorized users via direct download through the Marketplace.
Content of the Dataset
The dataset includes generation and performance metrics associated with specific self-consumption assets.
Asset identification:
- Technical identifiers: Alphanumeric codes are used for the managing entity (company) and the monitoring equipment (deviceName).
- Privacy by design: Personal data, sensitive commercial information, and direct physical locations are not included, ensuring end-customer anonymity.
Format of the Dataset
Data is structured in an optimized and interoperable JSON format, following a public ontology defined using JSON-Schema.
Dataset Structure (Conceptual Example):
| Field | Description | Example |
|---|---|---|
| company | Technical identifier of the managing entity (anonymized). | "E00001" |
| deviceName | Unique identifier of the monitoring equipment. | "Logger-10235593..." |
| startTime | Start timestamp of the reading (ISO 8601). | "2025-01-02 15:00:00" |
| totalPvPerformanceKWh | Value of total accumulated photovoltaic performance in kWh. | 2179.71 |
| pvGenerationData | Value of hourly photovoltaic generation in kWh. | 11.99 |
Relationship with Algorithms
This data product is designed to power advanced digital services within the energy ecosystem, such as:
