What is the Generation Based Incentive (GBI) in Delhi?

Under the Delhi Solar Policy 2024, the Delhi Government provides a Generation Based Incentive (GBI) of ₹3.00 per unit for residential rooftop solar for 3 years, directly credited on top of the Central PM Surya Ghar subsidy of up to ₹78,000!

Can apartment owners and flats in Delhi install solar?

Yes! Delhi's solar policy allows Virtual Net Metering (VNM) and Group Net Metering (GNM). This permits Resident Welfare Associations (RWAs) and apartment owners to install community solar panels on common terrace space and share energy credits across multiple individual electricity meters.

How do BSES and Tata Power (TPDDL) net meters work?

BSES and TPDDL replace your standard electric meter with a smart bi-directional net meter. Any solar units produced during peak day hours that you do not consume are exported to the grid, earning you bill credits that offset night-time consumption.
