Dr. Wan Dee Kunchurayakong sold all her 46.08% stake in solar energy company SPCG, marking her exit from the renewable energy business she pioneered in Thailand starting 2010. Her entrepreneurial journey is notable: she faced rejection from 12 banks before securing financing, developed 37 solar projects with ~260 MW capacity across 10 provinces (2014), accumulated 18 billion baht in debt over 14 years, and became known as the "Solar Farm Queen." Her story exemplifies persistence in cleantech entrepreneurship and lessons on planning, resilience, and risk-taking in emerging sectors.
