Under the Ministry of New and Renewable Energy (MNRE), residential rooftop solar installations in Tamil Nadu are entitled to attractive direct bank transfer (DBT) subsidies:
Small 1-2 BHK Homes • 120-140 Units/mo
2-3 BHK Homes (1 AC) • 240-280 Units/mo
Villas & Independent Houses • 360-1200 Units/mo
Offices, Schools, Hospitals, Factories
A bidirectional net meter replaces your traditional electricity meter. It records both the units of electricity you consume from TNEB and the units of clean solar electricity your rooftop sends into the grid.
When your house generates more solar units than you consume during daylight, excess power flows into the TNEB grid, spinning your meter backward and banking credits!
At night, you draw power from TNEB. Your bi-monthly electricity bill is calculated only on the Net Difference (Units Consumed − Units Exported).
The EB grid acts as your infinite virtual energy storage. No expensive battery replacement costs every 4 years, delivering an accelerated 3-4 year ROI!
