CH-POA300 is a dataset of hourly solar irradiance maps projected onto tilted surfaces (analogous to monofacial solar panels).
- Spatial resolution: 300 m
- Coverage: Switzerland

Two temporal extents are available, depending on the number of surface orientations (azimuth–tilt combinations):

1. Long-term

• Period: 2004–2020
• Orientations:
• Azimuth: 180° (South)
• Tilts: 0°, 35°, 60°, 90°

2. Typical year

• Period: 2016
• Orientations:
• Azimuths: 0° (North), 90° (East), 135°, 180° (South), 225°, 270° (West)
• Tilts: 0°, 3°, 8°, 15°, 25°, 35°, 45°, 60°, 80°, 90°

Notes

• Azimuth angles: 0° = North, 90° = East, 180° = South, 270° = West
• Tilt angles: 0° = horizontal, 90° = vertical

Additional data

• Seasonal and annual statistics derived from the maps are included.
• Methodology and quality assessment are documented in CH-POA300-v#-specs.pdf.
