The year 2026 heralds the dawn of commercialization for space-based solar power, signifying a pivotal moment in the cross-industry convergence of the photovoltaic (PV) and aerospace sectors. Recently, two prominent space energy alliances have been formed, with leading PV enterprises such as GCL Group, Trina Solar, and JA Solar venturing together into the aerospace arena. Space-based solar power is rapidly transitioning from conceptual verification to in-orbit testing and small-scale commercialization, with the contours of a trillion-yuan market beginning to take shape. Analysts highlight that space-based solar power does not constitute the core of a new technological revolution; rather, it represents an extension of PV technology applications. Despite the absence of a mature business model or significant cash flow in this field, with multiple in-orbit tests slated to commence this year, the space-based solar power market is projected to expand several-fold over the next decade, emerging as a fresh growth engine for the PV industry.
