China-based Astronergy’s ASTRO N7 615 W solar module ranked No. 1 in PV Magazine’s latest outdoor test evaluating TOPConPV modules for real-world energy yield efficiency. The module led in both energy yield per watt peak (Wh/Wp) and energy yield per surface area (kWh/m²), outperforming competitors in actual performance. This result was attributed to its advanced TOPCon 4.0 cell architecture, Super Multi Busbar (SMBB) technology, enhanced bifaciality, and low degradation rate, all of which contributed to its superior field performance in long-term testing.
