Conclusion
A project is defined by its location, meteorological data and system parameters, after which the PV array and inverters are configured from an extensive component database. Simulations then estimate energy production, losses and performance over time, and 3D modeling tools quantify shading losses. Reports cover technical and financial results, including payback periods and profitability.
Solar energy engineers, renewable energy consultants and research institutions use it, and researchers and educators apply it to study PV system behavior. The PRO license is sold as an annual license at CHF 700 per year, with prices published in the official shop.
