Use in Antalya and Solar Nexo support
Antalya's long sunshine duration and hot summers make durability and temperature behavior important in panel selection. The panel's documents list TUV Nord test reports for salt mist, dust-sand, ammonia and PID; in coastal projects, these reports are worth considering. The Solar Nexo team provides supply, design, installation, commissioning and after-sales technical support; the datasheet can be downloaded from this page. Theoretically, according to PVGIS data, 1 kWp produces about 1,656 kWh/year in Antalya; for a single 425 Wp panel, this comes to about 704 kWh/year (excluding shading, tilt and system losses).
