Engineering Protocol
Precision Rooftop Assessment
Before placing a single panel, Voltmen Solar engineers conduct an on-site structural audit. Gurgaon homes have unique architectural characteristics — from multi-story builder floor parapets to water tanks.
1. Structural & Load Audit
We inspect RCC slab thickness, reinforcement pillars, and wind load capacity (designed for up to 150 km/h gusts during northern Indian summer squalls).
2. 3D Shadow Modelling
Using digital sun-path simulation, we calculate shade profiles cast by mumty rooms, overhead Sintex water tanks, and adjacent 4-story floors across 365 days.
3. Terrace Pergola Elevation
Want to keep 100% of your roof space? We engineer elevated 8–10 ft GI structures that turn your terrace into a shaded recreational garden while harvesting solar energy above.
4. Electrical Feasibility
Audit of existing DHBVN sanctioned load, main electrical distribution box (MCB), dedicated chemical earthing bore location, and shortest cable run paths to minimize DC line loss.

DHBVN Net-Metering:
How You Earn Bill Credits
In Gurgaon, rooftop solar operates under the Dakshin Haryana Bijli Vitran Nigam (DHBVN) net-metering framework. During peak daytime hours when solar production exceeds household usage, your excess electricity flows into the city grid.
Bi-directional Smart Meter: Records electricity imported from DHBVN and electricity exported by your solar panels with 15-minute interval logging.
1:1 Energy Offsetting: Exported units directly neutralize imported peak units (valued at up to ₹8.20/unit for Gurgaon residential slabs).
Annual Settlement Roll-Over: Surplus units generated in sunny months (April–October) carry forward to offset winter consumption until the March 31 financial year settlement.
Zero Discom Paperwork for Homeowner: Voltmen Solar liaises with DHBVN subdivision offices across DLF, Sector 14, Sector 18, Sector 31, and Kadipur directly.

Common Queries
Residential Solar FAQs
Everything Gurgaon homeowners ask before scheduling a rooftop solar installation.
How long does residential solar installation take in Gurgaon from start to finish?▼
Physical roof installation is completed in just 2 to 3 working days by Voltmen Solar’s certified in-house engineering crew. The entire net-metering process with DHBVN (application, feasibility sanction, bi-directional meter testing at the Kadipur lab, and final commissioning) takes approximately 25 to 35 days.
Will solar panel installation damage my terrace waterproofing or roof tiles?▼
No. Voltmen Solar employs non-penetrative mounting techniques and heavy-duty chemical anchoring (Hilti fasteners) specifically designed for RCC roofs in Gurgaon. For elevated pergola structures, anchor base plates are sealed with industrial grade elastomeric waterproofing membranes, ensuring zero water seepage.
Can I install an elevated solar pergola structure to keep 100% of my terrace usable?▼
Yes! Elevated pergola solar structures are our most popular option for Gurgaon builder floors and kothis in DLF, Sushant Lok, and South City. We elevate the panels 8 to 10 feet above roof level using hot-dip galvanized iron (GI) pillars, creating a sheltered rooftop canopy for family gatherings, terrace gardens, or evening walks.
How does DHBVN net-metering calculate bill credits for Gurgaon residential homes?▼
DHBVN installs a bidirectional smart meter. Any solar energy your home does not immediately consume is exported to the grid, spinning your meter backwards. At the end of the billing cycle, exported units are subtracted from imported units at DHBVN domestic rates (up to ₹8.20/kWh). Surplus units roll over month-to-month until March 31.
How do I claim the ₹78,000 PM Surya Ghar Muft Bijli Yojana subsidy?▼
Voltmen Solar is an officially empaneled vendor on the national PM Surya Ghar portal. We handle your online registration, discom feasibility approvals, work-start intimation, and post-installation commissioning certificate uploads. The subsidy (₹30,000 for 1kW, ₹60,000 for 2kW, and ₹78,000 for 3kW and above) is directly deposited into your bank account via DBT within 30–45 days.
What warranties and performance guarantees come with residential solar?▼
Every Voltmen Solar residential installation includes a 25-year linear performance warranty on solar panels (guaranteeing 84.8%+ efficiency at Year 25), a 10-year replacement warranty on on-grid string inverters, and a 5-year comprehensive workmanship warranty backed by our dedicated Gurgaon service fleet.
