What Makes a Solar Company the Best Choice in Delhi NCR?
Defining the "best" solar company goes beyond comparing prices. The right solar partner should demonstrate expertise across multiple evaluation criteria — from project experience and equipment quality to installation standards and long-term support.
Solar Experience
A solar company's track record speaks volumes. Evaluate the number and type of projects completed — residential, commercial, and industrial. Companies with diverse experience across rooftop solar segments understand the unique challenges of each property type, from independent houses to large manufacturing facilities.
Quality of Solar Panels
The solar panel is the core of your system. Key considerations include module technology (Mono PERC, TOPCon, bifacial), cell efficiency, annual degradation rate, product and performance warranty, and manufacturer reliability. Choosing panels from the best solar panel brands ensures long-term generation and reliability.
Inverter Quality
The inverter converts DC solar power into usable AC electricity. Inverter selection affects system efficiency, monitoring capabilities, reliability, safety, and long-term operation. String inverters suit most residential installations, while commercial projects may require central or multi-MPPT inverters for optimal performance.
Engineering & System Design
Proper engineering includes rooftop assessment, shadow analysis, structural assessment, system sizing, string design, and generation estimation. A well-designed system maximises generation while accounting for rooftop-specific challenges such as water tanks, mumty rooms, and seasonal shadow patterns.
Installation Quality
Installation workmanship directly determines system performance and safety. Key areas include mounting structures (hot-dip galvanised), waterproofing, cable management, earthing, electrical protection (DCDB, ACDB, SPD), and adherence to safety standards. Poor installation can void warranties and create long-term problems.
After-Sales Support
A 25-year asset requires reliable post-installation support: performance monitoring, preventive maintenance, troubleshooting, AMC (Annual Maintenance Contract), warranty claim support, and responsive service. Companies with local Delhi NCR presence offer faster maintenance access.
Transparent Pricing
Customers should compare total project cost — equipment + installation + approvals + warranty + maintenance — rather than simply comparing the advertised panel price per watt. A complete, transparent quotation helps avoid hidden costs and ensures accurate ROI projections. Use our solar system cost guide for detailed pricing frameworks.

Net Metering for Rooftop Solar in Delhi NCR
What Is Net Metering?
Net metering is a billing arrangement where surplus electricity generated by your rooftop solar system is exported to the grid. A bidirectional meter tracks both import and export, and the DISCOM credits your account for exported units.
How Net Metering Works
During daytime, your solar system generates electricity. If generation exceeds consumption, surplus flows to the grid (export). At night or during low-generation periods, you draw from the grid (import). The DISCOM adjusts your bill based on the net difference between import and export.
Who Can Apply?
- Owners of residential or commercial property
- Properties with sufficient rooftop area
- Valid electricity connection with the DISCOM
- Grid-connected solar system installed by empanelled vendor
Documents Required
- Electricity bill and consumer number
- Identity and address proof
- Property ownership documents
- System technical specifications
- Vendor credentials and test reports
Net metering significantly improves solar ROI by allowing you to offset electricity costs even when your system isn't generating. The rooftop solar vs traditional electricity comparison demonstrates the long-term financial impact with net metering.
