11 Jul, 2025

In India’s race towards clean energy, ground-mounted solar EPC projects are leading the charge in powering industries, utilities, and rural areas with scalable and sustainable solutions. As solar infrastructure spreads across vast acres of land, businesses and governments alike are realising the unmatched benefits of land-based solar systems.

Unlike rooftop projects, which are often space-restricted, ground-mounted solar EPC solutions offer large-scale implementation, better design flexibility, and enhanced ROI. In this comprehensive guide, we’ll explore every layer of ground-mounted solar, from EPC design and layout to execution strategy and financial returns.

Whether you're planning a ground solar project in India or just exploring the potential of utility-scale EPC contractors, this blog will walk you through the vital elements that make such projects successful, especially when handled by trusted experts like Rayzon Green.

The Design and Planning of Ground-Mounted Solar EPC Projects

Design is the backbone of any successful ground-mounted solar EPC project. It influences energy output, land usage efficiency, and future maintenance.

Key Elements of EPC Design for Land-Based Solar

  • Site Survey & Feasibility: Conducting a comprehensive terrain, shadow, and environmental assessment.
  • Solar Plant Layout Design: Optimising module placement and tilt for maximum sunlight exposure.
  • Soil & Structure Analysis: Engineering foundations based on soil type and wind load.
  • Electrical Design: Cabling, inverter placement, and grid connectivity tailored for open-access solar EPC or utility-tied systems.

At Rayzon Green, we use state-of-the-art tools to create precise BOQ (Bill of Quantities) and solar EPC layout plans tailored to site-specific needs.

EPC Installation Process: Turning Blueprints into Energy

The solar EPC installation process involves Engineering, Procurement, and Construction—the triad that turns concept into commission-ready infrastructure.

Our Ground-Mounted EPC Execution Steps:

  1. Land Development: Clearance, fencing, and leveling based on land requirement for solar EPC.
  2. Procurement: High-efficiency modules, inverters, transformers, and cabling sourced from Tier-1 manufacturers.
  3. Construction: Piling, structure mounting, panel installation, inverter room setup, and SCADA integration.
  4. Commissioning: Testing and synchronization with the grid.

Rayzon Green follows robust safety and quality protocols to deliver comprehensive solar EPC solutions.

CAPEX and Financial Planning for Ground-Mounted Solar

One of the most critical aspects of any solar project is its return on investment. Here’s how ground-mounted solar EPC systems make financial sense:
