This study explores the evolution of Türkiye's solar energy research network from 1991 to 2020 using bibliometric and project data focusing on its growth and international collaboration. Results reveal a significant increase in solar energy publications, with Türkiye's global output share increasing from 0.46 % in 1991–2000 to 1.38 % in 2011–2020. The period covering 2001–2010 emerges as a critical fermentation phase, marked by expanding collaborations and the foundation of key partnerships. Türkiye's strategic location and active participation in the EU Framework Programmes have enabled it to serve as a bridge for knowledge exchange between Europe and the Middle East and North Africa region. While universities remain central, private-sector participation has grown. The network has become more democratized, incorporating diverse actors and reducing dependence on a few dominant institutions. Individual researchers with dual affiliations have played key roles in fostering international ties for certain countries. This research provides insights into the dynamics of solar energy collaboration and identifies key factors that influence such partnerships at various levels to enhance Türkiye's role in global energy transitions.
