This study investigates public acceptance of photovoltaic (PV) solar energy in Myanmar using the Theory of Planned Behavior (TPB), focusing on various demographic groups in 2023. The 337 respondents across different regions provided a comprehensive overview of public attitudes. The survey examined subjective norms, attitudes, perceived behavioral control, willingness to pay, and intention to adopt (PV) solar technology. Results indicated a high level of awareness, with 98% familiar with (PV) solar and 95% knowledgeable about its panels. However, adoption rates were low at 20%. Subjective norms positively influenced attitudes, as 81% observed their social circles using (PV) solar and 80% found it convenient. Environmental concerns were minimal, with 75% not worried about (PV) Solar’s impact and 85% recognizing its carbon reduction benefits. The initial cost was a significant barrier, with 80% finding it too expensive, despite 96% believing in future cost savings. Perceptions of self-efficacy showed strong support for (PV) solar as a solution for electricity demand (90%) and interest in rooftop solar panels (87%). From an aesthetic perspective, only 14% described solar panels as unattractive. The study recommends financial incentives, education campaigns, and improved (PV) solar access, with government and stakeholder support to boost acceptance and adoption in Myanmar.
