Which parameters are taken into account? 
There are many parameters that are taken into account to generate the simulation results. Among the most relevant:
- Coordinates (latitude, longitude, altitude)
 - Historical irradiance
 - Sun position (elevation, azimuth)
 - IAM
 - Ambient temperature
 - Wind speed/direction
 - Mounting system
 - Module type
 - Cell temperature
 - I-V curves (specific to the module)
 - Cell arrangement
 - Mechanical characteristics of the components (size, weight)
 - String configuration
 - Inverter performance curves
 - String input voltage
 - AC output power and clipping
 - Automatic string size calculation
 - Available MPPTs
 - Available inputs per MPPT
 - String orientations based on the 3D scene
 - Losses (wiring, connection, snow, soiling, shadows)
 - Consumption data
 - Tariffs
 - Taxes
 - Regulations
 - Battery technology (LFP, NMC, LMO, LTO...)
 - Battery degradation
 - PPA
 - Financing
 - NPV
 - IRR
 - O&M costs
 - Discount rate
