• Multiple Orientations
• 3D Module Layout
• P50 / P90 report
• Miscellaneous improvements

3. Page 3Page 3
Multiple Orientations
• Up to eight different orientations
• Two specific orientations can be mixed (coupled to the same inverter)
"System summary" window
available from different dialogs
General overview of the parameters:
Orientations, sub-arrays, shading 3D fields defined.
Identifies the uncompatibilities between these 3 entities
(orientation and areas matching)

4. Page 4Page 4
3D Module Layout
• Link between 3D scene editor and module layout
In the 3D scene construction
the modules can be placed
manually or automatically
In the module layout dialog
the 3D scene can be
consulted to get an overview

Production previsibility – P50 / P90
• Variability ( RMS or s ) determination
− Based on the observed Meteo data variability
− Increased by other uncertainties of the simulation process
(PV module parameters, inverter, soiling, degradation):
• Each uncertainty is quantified by a RMS probability, which are added
quadratically.
• P90 yield evaluation = P50 - 1.28 * s
