SolarSavings
To claim both the PM Surya Ghar central subsidy and the lucrative Delhi Generation-Based Incentive (GBI), your rooftop solar plant must be installed by a localized, empanelled vendor registered under your specific Delhi DISCOM (BSES Rajdhani, BSES Yamuna, TPDDL, or NDMC).
While the National Vendor Directory lists over 15,000 installers pan-India, this localized guide will help you navigate the specific vendor landscape within the National Capital Territory (NCT) of Delhi.
1. Navigating the Delhi DISCOM Vendor Jurisdictions
Delhi's electricity distribution is uniquely privatized and divided among three primary DISCOMs. When selecting a vendor for your net-metering application, you must verify that they are actively empanelled with your specific DISCOM, otherwise, your application for the Delhi Solar Policy GBI will be rejected.
South & West Delhi (BRPL)
BSES Rajdhani Power Limited serves areas like Vasant Kunj, Dwarka, and Saket. Vendors operating here must be familiar with BRPL's specific smart meter integration protocols.
East & Central Delhi (BYPL)
BSES Yamuna Power Limited serves areas like Laxmi Nagar, Mayur Vihar, and Chandni Chowk. Vendor availability here is high, leading to highly competitive quotes.
North Delhi (TPDDL)
Tata Power Delhi Distribution Limited serves areas like Rohini and Pitampura. TPDDL has the fastest net-metering turnaround time, but strict vendor compliance rules.
2. How to Shortlist the Best Solar Installers in Delhi
Delhi faces unique environmental challenges, including high PM2.5 particulate pollution and extreme summer temperatures exceeding 45°C. Therefore, your vendor selection criteria must adapt to these local realities:
- Dust & Pollution Mitigation: Ask your vendor if they provide an automated sprinkler system or recommend a specific cleaning schedule. Heavy dust settling on panels in Delhi can reduce generation by up to 20% within weeks.
- High-Temperature Module Selection: Request Tier-1 DCR modules with a low Temperature Coefficient (e.g., TopCON panels). Standard polycrystalline panels suffer severe voltage drops during Delhi's peak summer months.
- High-Rise Installation Expertise: Many residential installations in Delhi occur on 3rd or 4th-floor rooftops of builder floors. Ensure your vendor has the scaffolding expertise and structural clearance from the Municipal Corporation of Delhi (MCD) if required for raised structures.
3. Accessing the Official Delhi Vendor Directory
To download the official, up-to-date PDF list of empanelled vendors authorized to operate in Delhi:
- Visit the central PM Surya Ghar portal. (Read our complete National Vendor List Guide for detailed portal navigation).
- Select "Delhi" from the state dropdown.
- Select your specific DISCOM (BRPL, BYPL, TPDDL, or NDMC).
- Filter the resulting list by vendors who have a localized office address within the NCT for faster post-installation service and O&M (Operations & Maintenance).
A Note on the Delhi GBI for Group Housing Societies (CGHS)
If you represent an RWA or CGHS in areas like Patparganj or Dwarka, you must select an EPC vendor experienced in commercial-scale multi-metering. The Delhi government provides a separate ₹2,000/kW capital subsidy specifically for CGHS installations, which requires a specialized approval workflow with the Energy Department.
