Abstract: Photovoltaic (PV) junction boxes play a crucial role as Balance of System (BoS) components, facilitating the safe and efficient transmission of power from solar modules. Junction boxes play a vital role, yet they frequently encounter reliability issues, particularly in the face of India's varied and severe environmental conditions. This analysis explores the main failure modes of PV junction boxes within the Indian solar industry, assesses their economic impacts, and highlights significant regulatory deficiencies. The examination uncovers prevalent failure mechanisms, including thermal degradation, diode burnout, moisture ingress, and corrosion, which are intensified by elevated ambient temperatures, dust, and humidity. The economic implications of these failures include diminished energy production, escalated operations and maintenance costs, and an increased risk of fire hazards, all of which directly impact return on investment. Furthermore, the absence of enforceable standards in India and the lack of policy incentives for BoS components have resulted in an influx of substandard imports and constrained domestic innovation. This paper emphasizes the critical necessity for strong regulatory frameworks, which should encompass mandatory BIS certification, targeted incentives for specific components, and enhanced investment in quality testing infrastructure. It is crucial to tackle these gaps to guarantee the enduring performance, safety, and sustainability of solar installations as India moves forward in its shift towards a clean energy future.
