Important notice

Simulation results produced by SADE PVInvest are indicative estimates only. They are generated using publicly available meteorological datasets (PVGIS 5.2, NASA POWER) and open-source modelling libraries (pvlib), and are provided for preliminary decision-support purposes.

Results do not constitute financial advice, an investment recommendation, or a bankable engineering report. A certified PV energy yield assessment (e.g. IEC 61724-1 compliant report by a licensed engineer) should be obtained before making any investment or financing decision.
