Which projects is it suitable for?
Suitable for large commercial roofs, business roofs and ground-mounted PV sites. A roughly 10 kWp installation uses 20 panels of 520 Wp; panel size and weight should be checked from the datasheet in structural calculations.
Use in Antalya and Solar Nexo support
Antalya's long hours of sunshine and hot summers make durability and temperature behaviour important when choosing a panel. The panel's documents list TÜV Nord test reports for salt mist, dust and sand, ammonia and PID; these reports are worth considering for projects along the coast. 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 in Antalya produces about 1,656 kWh/year; for a single 520 Wp panel this comes to about 861 kWh/year (excluding shading, tilt and system losses).
