Understanding project phases
Solar EPC projects follow four distinct implementation phases:
1. Engineering Phase
This initial phase involves comprehensive site assessment and system design, including:
- Site surveys and solar resource assessment
- Detailed electrical and structural designs
- Performance simulation and optimization
- Technical specifications documentation
2. Procurement Phase
The second phase focuses on material and equipment acquisition:
- Solar panel and inverter selection
- Mounting structure procurement
- Quality control measures
- Supply chain management
3. Construction Phase
This phase involves physical implementation:
- Site preparation and civil works
- Mounting structure installation
- Solar panel placement
- Electrical system integration
4. Commissioning Phase
The final phase ensures system functionality:
- Testing and inspection
- Grid connection
- Performance verification
- Handover documentation
How does solar EPC model work in India?
In India, solar EPC projects are governed by MNRE (Ministry of New and Renewable Energy) guidelines and state-specific regulations. Maharashtra and Gujarat lead in commercial solar installations, with typical project sizes ranging from 100kW to 1MW for industrial applications.
