SYSTEMATIC EXECUTION

Our 6-Phase Engineering Architecture

Every VASA solar installation follows a proven, precision-guided workflow to guarantee maximum 25-year energy yield and zero structural risk.

📏

On-Site Rooftop Survey & 3D Shadow Modeling

Precision physical assessment of your terrace architecture and solar potential.

Our senior solar engineers visit your premises with digital laser rangefinders and solar pathfinders. We analyze parapet wall heights, adjacent building shadow vectors across all 12 months, roof dead-weight structural load capacity, and existing electrical distribution boards.

Phase Deliverables:

✓ 3D Shading Vector Simulation
✓ Shadow-Free Usable Area Map (sq.ft.)
✓ Sanctioned Load vs Generation Sizing
✓ Optimal Earthing Pit & Cable Run Route

📐

Electrical Architecture & UP DISCOM Filing

Custom CAD blueprint and upfront government net-metering approvals.

We produce custom Single-Line Diagrams (SLD), calculate MPPT string inverter matching voltages, and determine cable gauge sizing to minimize DC transmission loss (<1.5%). Simultaneously, our Lucknow liaison desk files your application on the UP DISCOM portal (MVVNL / PVVNL / DVVNL / PuVVNL) for grid connectivity feasibility.

Phase Deliverables:

✓ CAD Rooftop Layout & String Design
✓ DISCOM Portal Application Registration
✓ Turnkey Proposal with Detailed ROI Timeline
✓ PM Surya Ghar Subsidy Eligibility Token

📦

Tier-1 Component Procurement & Flash-Testing

Quality verification of modules, inverters, and heavy-gauge steel structures.

We dispatch pre-tested Monocrystalline Bi-Facial modules and high-efficiency inverters from our certified partner ecosystem (Tata, Adani, Waaree, Vikram, Luminous, Microtek). Each module batch is inspected against factory flash-test reports to ensure peak rated wattage output.

Phase Deliverables:

✓ Factory Flash-Test Power Output Reports
✓ 80-Micron Hot-Dip Galvanized GI Steel
✓ UV-Stabilized Double-Insulated Solar DC Cables
✓ IP65 Weatherproof ACDB & DCDB Enclosures

🏗️

Rooftop Mechanical Fabrication & Panel Mounting

Heavy-duty structural erection with zero roof leakage guarantee.

Our certified structural technicians assemble the elevated HDG framework, anchoring into roof columns or terrace slabs with industrial chemical epoxy fasteners or pre-cast concrete ballast blocks (zero-drilling). Modules are clamped with stainless steel 304 hardware, followed by multi-layer waterproofing inspection.

Phase Deliverables:

✓ Zero Roof Leakage Chemical Epoxy Seals
✓ 150 km/h Wind-Gust Structural Stability
✓ Usable Terrace Height Clearance (Pergola Option)
✓ Stainless Steel SS304 Module Clamps

⚙️

Electrical Integration & Multi-Point Safety Validation

Earthing, lightning arrestor, inverter sync, and safety protocols.

Our electrical engineers install 3 dedicated copper-bonded chemical earthing pits (Inverter, DC System, Lightning Arrestor) with earthing resistance certified under 2 Ohms. We test Open Circuit Voltages (Voc), short-circuit currents (Isc), insulation resistance, and sync the smart IoT WiFi inverter data gateway.

Phase Deliverables:

✓ 3 Dedicated Chemical Earthing Pits (<2Ω)
✓ Class-II SPD Lightning & Surge Protection
✓ Smart IoT WiFi Mobile Monitoring Activation
✓ Full Insulation & Polarity Safety Audit

✅

UP DISCOM Net-Metering Sync & Subsidy Release

Joint inspection, bi-directional meter testing, and customer handover.

VASA's liaison engineers coordinate the on-site inspection with UP DISCOM sub-divisional officers. The existing energy meter is replaced with a certified bi-directional net-meter. The system is synchronized with the UP grid, and your PM Surya Ghar subsidy claim is submitted for direct bank transfer credit.

Phase Deliverables:

✓ Bi-Directional Net-Meter Installation & Sealing
✓ Official UP DISCOM Commissioning Certificate
✓ PM Surya Ghar National Portal Subsidy Filing
✓ Comprehensive Handover Kit & 25-Year Warranty

OUR ENGINEERING STANDARDS

Why Our Execution Stands the Test of Time

We build solar plants to withstand extreme UP summer heat, monsoon gales, and decades of relentless sun exposure.

🛡️

Zero Roof Leakage Guarantee

We use chemical epoxy anchor seals or pre-cast concrete ballasts. We never drive raw destructive bolts into your terrace waterproofing.

⚡

Triple Chemical Earthing (<2Ω)

Dedicated independent earthing pits for Inverter, Solar Array, and Lightning Protection using copper-bonded rods and Bentonite compound.

🌀

150 km/h Wind Load Rating

Hot-dip galvanized heavy GI steel structure engineered with proper tilt angles (24–27° for UP) to maximize generation and withstand storms.

📱

Real-Time Cloud IoT App

Track your daily units generated, monthly savings, and CO2 offset from anywhere in the world right on your mobile smartphone.
