SOLAR

VPB offers end-to-end solar capabilities from engineered products and real-time monitoring to full-scale installations. Our approach is performance-driven: we design and deliver systems that maximize yield, simplify operations and comply with technical and statutory requirements.

SOLAR PRODUCTS à ACDB & HT VCB (In-house, Type-Tested)

What we supply: VPB manufactures and supplies type-tested power distribution products tailored for solar installations, including AC Distribution Boards (ACDB) and HT Vacuum Circuit Breaker (VCB) panels. These are engineered to integrate with inverters, transformers and grid interfaces while meeting stringent electrical safety and performance standards.

ACDB à Role & benefits

  • Function: Distributes alternating current from inverters to downstream loads and protection devices.
  • Protection & Control: Houses circuit breakers (MCCB/ACR), surge protection devices (SPD), metering and isolators for safe and controlled distribution.
  • Key technical considerations: Supports high AC voltages (typical designs up to 800V AC), modular breakers, weatherproof enclosures for outdoor plants and clear metering for performance verification.
  • Why it matters: A correctly specified ACDB reduces downtime, simplifies protection coordination, and supports accurate energy accounting and maintenance operations.

HT VCB (11kV–33kV) à Role & benefits

  • Function: Provides high-voltage switching and protection for grid-connected equipment, particularly crucial for utility-scale and substation-level integrations.
  • Vacuum interruption: Vacuum circuit breakers extinguish arcs quickly and reliably, providing low maintenance and high switching reliability.
  • Protection & grid readiness: Includes relays, metering, interlocks and remote monitoring – critical for safe grid connectivity and protection of transformers and inverters.
  • Why it matters: Robust HT switching protects your asset base and ensures safe, standards-compliant grid interactions for large solar farms and industrial generation.

Compliance & quality

  • All product designs are aligned with IEC and applicable local standards. Type testing and vendor quality assurance are used to validate safety, thermal performance and operational reliability.

 

SCADA SOLUTIONS (Monitoring & Control)

What SCADA does for your solar plant

SCADA (Supervisory Control and Data Acquisition) is the operational backbone for visibility and control. For commercial and utility installations, VPB SCADA solutions provide real-time monitoring, granular analytics, remote troubleshooting and centralized control enabling predictable energy delivery and rapid response.

Core capabilities

  • Real-time monitoring: Track PV string and inverter performance, AC output, and grid export in live dashboards.
  • Data-driven analytics: Generate PR (Performance Ratio), energy yield reports, fault trend analysis and PVsyst comparison outputs to measure actual vs expected performance.
  • Remote access & control: Secure remote access for operations teams to view alarms, change control settings, and perform initial diagnostics without site visits.
  • Event & alarm management: Prioritized alarms, event logs and automated alerts to speed fault identification and corrective action.
  • Integration: Interfaces with in-house ACDB telemetry, inverter protocols and plant SCADA to present a unified operational picture.

Operational benefits

  • Improved uptime by reducing mean time to detect and repair (MTTD/MTTR).
  • Better yield through proactive maintenance and performance optimization.
  • Centralized management for multiple plants or rooftop portfolios.

SOLAR INSTALLATION

Complete Turnkey EPC (Engineering, Procurement & Construction)

Why “EPC” here

The brochure identifies VPB as a turnkey solar solution provider using the phrase “Complete Solar EPC.” In this context EPC means VPB accepts single-point responsibility for Engineering (system design & simulation), Procurement (sourcing of modules, inverters, BOS & electrical equipment) and Construction (civil, mechanical & electrical installation), followed by Commissioning and O&M handover. This model reduces client coordination overhead and aligns outcomes to contractual performance metrics.

Scope of VPB’s Solar EPC delivery

  • Feasibility & bankability: Land evaluation, shade studies, yield projections and financial/feasibility reporting.
  • Design & simulation: PVsyst analysis, stringing diagrams, earthing studies and 3D layout modeling for shade minimization and structural optimization.
  • Civil & structural works: HDGI structures, foundations and civil works that meet design wind loads and corrosion protection requirements.
  • Electrical integration: ACDB, HT VCB panels, cable routing, earthing, transformer & grid interconnect works.
  • Approvals & liaison: Government approvals, grid-connection clearances and compliance documentation support.
  • Testing & commissioning: Commissioning protocols, performance acceptance tests and handover documentation.
  • Operations & Maintenance: Post-commissioning service packages, SCADA-backed remote monitoring and preventive maintenance plans.

Project types supported

  • Rooftop / On-Shed installations for industries and commercial buildings.
  • On-Grid & utility-scale solar farms.
  • Off-Grid solutions with battery-backed microgrids.
  • Walkway/canopy solar and hybrid generation systems.

Outcomes you can expect

  • Predictable energy generation validated against simulation outputs.
  • Clear contract responsibility and single-point coordination.
  • Long-term operational visibility with defined O&M SLAs.
