All Climate type parameters are sourced from the IFS forecast model for the window from the current day to DAY-10. The spatial resolution of the IFS model data is 0.1° (~11 km).
The Solar type parameters with an accuracy of 0.00083° (~90 m) consider horizon shading.
* This parameter needs a PV system defined in the request, at least in a minimal setup as follows:
<pv:system installedPower="1">
<pv:module type="CSI"/>
<pv:inverter/>
<pv:losses/>
