Solar Panel Subsidy in Delhi

Delhi Solar Policy & Incentive Brief (2026)

Delhi has the most layered solar incentive structure of any Indian state or union territory, making it unique in offering both a capital subsidy and a generation-based incentive (GBI) simultaneously. Beyond the PM Surya Ghar central subsidy of up to ₹78,000, Delhi's own policy adds a GBI of ₹3 per unit of solar electricity generated for the first 5 years of the system's operation. For a 3kW system generating approximately 13–14 units per day, this translates to ₹14,000–₹18,000 in additional income over the GBI period — a meaningful boost that is not available in any other Indian state. Delhi has two primary DISCOMs: BSES (Rajdhani and Yamuna) covering south, west, and east Delhi, and Tata Power Delhi Distribution Limited (TPDDL) covering north and northwest Delhi. Both have operational online net metering portals, and approval timelines are among the fastest in India at 15–25 working days. The Delhi government also runs an awareness campaign through Mukhyamantri Solar Power Yojana, which provides technical assistance to residents unfamiliar with the application process. Air quality is a critical operational factor in Delhi — PM2.5 levels mean panels here lose 20–30% output if not cleaned every 10–12 days during the October–May dry season. However, the strong tariff and GBI combination means Delhi installations still achieve excellent ROI even with higher cleaning frequency. Delhi's dense apartment stock requires extra coordination: DDA flats and multi-unit buildings need a society resolution and a designated contact for DISCOM liaison. Group housing societies can install a shared rooftop system and distribute benefits across members through net metering.
