What is different about selling solar in Delhi
Delhi is the only jurisdiction here where a generation-based incentive has been paid per unit generated in addition to capital subsidy, which changes the payback arithmetic enough that quoting Delhi like any other state understates the return. Four licensees split the territory — BSES Rajdhani in south and west, BSES Yamuna in central and east, Tata Power-DDL in north-west, NDMC in the council area — and the applicable one is determined by address, not choice. Space is the binding constraint: most residential demand is DDA flats and group-housing societies, so common-roof allocation and society NOCs, not roof area, decide project feasibility.

Delhi net-metering capacity rule
BSES Rajdhani, BSES Yamuna, Tata Power-DDL and the NDMC area each administer net metering under DERC regulations, and Delhi has historically layered a generation-based incentive on exported or generated units on top of the central subsidy.
Net metering in Delhi
Regulator: Delhi Electricity Regulatory Commission (DERC)
Needs verification
Rooftop solar in this state is connected under the state electricity regulatory commission's net-metering regulations: the installer files an application with the local DISCOM, the DISCOM sanctions feasibility against the consumer's sanctioned load, the plant is installed by an empanelled vendor, and a bi-directional meter is installed after inspection before commissioning and credit settlement begin. Exact load caps, capacity ceilings, settlement period and fee schedule must be confirmed against the current DISCOM circular before quoting.
PM Surya Ghar subsidy in Delhi
Needs verification
PM Surya Ghar: Muft Bijli Yojana is a central (all-India) scheme, so residential consumers in this state are eligible on the same national basis, applying through the National Portal and a state-empanelled vendor, with the subsidy released to the consumer's bank account after installation and DISCOM inspection. Current slab amounts, any additional state top-up, and the state nodal-agency workflow must be verified before being shown to a customer.
Applications in Delhi route through Delhi Dialogue and Development Commission / DERC-registered empanelled vendors. The exact slab maths — ₹30,000/kW for the first 2 kW, ₹18,000/kW for the third, capped at ₹78,000 — is worked through in our PM Surya Ghar subsidy guide.
