Rooftop Solar & Consumer Adoption
PM Surya Ghar — TN registrations3.2 L of 10 L target (2026)
Rooftop solar capacity (cumulative)1,840 MW
TNPDCL net metering active connections31,620 active
Avg. subsidy processing time67 days actual (target 30)
TNPDCL bottlenecks — slow processing, limited empanelled vendors, low feed-in tariff — cited as primary barriers to rooftop solar adoption.
