PV Shading Database

Sep 6, 2016, 18:00 PM
This software is a simplified method for modeling the impact of arbitrary partial shading conditions on PV array performance. It implements a simple method for modeling shade loss: a database of shade impact results (loss percentages), generated using a validated, detailed simulation tool and encompassing a variety of shading scenarios. The database is intended to predict shading losses in crystalline silicon PV arrays and is accessed using basic inputs generally available in any PV simulation tool. Performance predictions using the database are within 1%–2% of measured data for several partially shaded PV systems and within 1% of those predicted by the full, detailed simulation tool on an annual basis.
