Unveiling the shadows: a qualitative exploration of barriers to rooftop solar photovoltaic adoption in residential sectors

Abstract

Abstract In the face of global climate change, the urgent shift towards renewable energy sources such as solar power is vital for reducing greenhouse gas emissions and fostering a sustainable future, presenting a universal challenge and opportunity for energy policy worldwide. India’s adoption of rooftop solar photovoltaic is pivotal due to its vast solar potential, which aligns with national goals to increase renewable energy capacity, reduce carbon emissions, and achieve energy security. Kerala’s geographical location offers abundant solar potential, making it a prime candidate for the adoption of rooftop solar photovoltaic systems. Coupled with the state’s strong commitment to renewable energy initiatives such as the ambitious “SOURA” (solar subsidy program by the Kerala State Electricity Board) project and various incentives for solar adoption, Kerala stands at the forefront of India’s transition towards sustainable energy solutions. Understanding the barriers to rooftop solar photovoltaic adoption in Kerala is crucial for tailoring effective policies and strategies that address specific hindrances from economic constraints to informational gaps. This study employs a qualitative research method to identify the barriers to rooftop solar photovoltaic adoption among households in Kerala. Through face-to-face interviews with a purposively selected sample of 52 households, the research aims to gain in-depth insights into the multifaceted challenges hindering the widespread adoption of solar energy in residential settings. The findings reveal several key barriers: financial barriers, informational barriers, technical barriers, regulatory barriers, social barriers, and psychological barriers. Sentiment analysis indicates that while there is a predominantly positive attitude towards solar photovoltaic adoption, there are significant concerns that still need to be addressed. Addressing these barriers with targeted policy interventions and public awareness campaigns could significantly enhance the adoption of rooftop solar photovoltaic systems in Kerala.
