Abstract/Summary:

---

We compare our steeply textured glasses under outdoor conditions at different sites in Germany and Spain. We find that the gain of SGGALBARINO G and SGGALBARINO P compared to SGGALBARINO T (nontextured glass) under 30° in mean average is between 1% and 13% in Germany and between 1% and 9% in Spain depending on solar cell type and weather conditions. On textured glasses no dust accumulation higher than on non-textured glasses could be found. So the efficiency gain keeps stable over a long period of time.
