Huasun Energy, a China-based manufacturer of heterojunction photovoltaic modules, has proposed a vertical PV system using its Kunlun HJT modules to address shifting electricity price dynamics. According to Huasun Energy, rising solar penetration has driven down midday electricity prices in regions like Spain and Germany, weakening returns from traditional south-facing PV plants. On June 26, at the “Global PV System Technology Trends 2025” conference by TaiyangNews, Huasun Energy advocated replacing Levelized Cost of Energy (LCOE) with Time-of-Day (TOD) value as a more relevant metric. Kunlun HJT modules, featuring 0BB technology and near-100% bifaciality, are vertically mounted to produce dual output peaks matching morning and evening price periods. Unlike TOPCon modules, which focus output at midday, Kunlun modules align better with high-value demand windows. Huasun Energy stated that this design reduces land use, balance-of-system costs, and storage needs while enhancing energy yield, weather resistance, and deployment flexibility.
