Cheap PV Modules Upend Solar Array Landscape?
2025-05-03
As PV module prices continue to fall, simple fixed East-West arrays are now cheaper and faster to install than the industry-standard single-axis tracked arrays. While single-axis trackers still significantly outperform East-West arrays in energy production per panel, their higher cost makes them less competitive in some regions, especially when facing extreme weather like hail. East-West arrays offer lower material and labor costs, less land usage, and increasing economic benefits as PV module prices decline. However, single-axis trackers retain an advantage in areas prone to hail due to their superior resilience. The optimal choice depends on location, weather conditions, and the balance between cost and risk.
