One-Second Solar Irradiance Measurements from 17 Oahu Stations

Seventeen measurement stations in southwestern Oahu, Hawaii, collected solar irradiance data at 1-second intervals over one year. The sensors are arranged in a 1-kilometer grid to support predictions of photovoltaic system output.

Use Cases

• Model photovoltaic output predictions at 1-second intervals using irradiance data from a 1-kilometer sensor grid.
• Analyze solar irradiance ramp rates and variability across 17 geographically distributed stations.
• Study spatial correlation of irradiance within a 1-kilometer grid to inform renewable energy grid integration.

Strengths

• High temporal resolution with 1-second measurement intervals.
• Spatial coverage from 17 stations arranged in a 1-kilometer grid.
• Data collected over a full year to capture seasonal variations.

Limitations

• Data format is HTML, which is not ideal for direct numerical analysis and requires parsing.
• Specific column definitions and sample data are unavailable, complicating initial data understanding.
• The dataset's age may limit its relevance for current solar technology modeling.
