Introduction:

With the global push toward renewable energy, solar photovoltaic (PV) systems have become a cornerstone of sustainable power generation. The success of any solar project hinges on the effectiveness of its EPC (Engineering, Procurement, and Construction) phase. This specialized training program, designed by Global Horizon Training Center, equips participants with the technical knowledge and practical tools required to ensure high-quality, efficient, and compliant execution of solar PV projects. It covers critical aspects such as system design and sizing, hybrid configurations, safety standards, performance modeling, and quality control—ensuring participants are well-prepared to support utility-scale and commercial PV installations.

Objectives:

By the end of the course, participants will be able to:

• Design and size PV systems based on energy requirements and site conditions

• Interpret and develop single-line diagrams (SLDs) for PV installations

• Apply international and local codes and standards for solar PV systems

• Understand hybrid system architectures and configurations

• Implement best practices for installation, commissioning, and quality control

• Conduct performance modeling and estimate energy yields using simulation tools

• Ensure safety and regulatory compliance throughout project execution

Course Methodology:

• Interactive technical lectures with visual and engineering schematics

• Hands-on exercises using simulation and design tools (e.g., PVsyst, Helioscope)

• Group case studies on real-world EPC projects

• SLD drawing sessions and troubleshooting scenarios

• Guided discussions on current standards, challenges, and innovations

Organizational Impact:

Organizations will benefit from:

• Enhanced internal EPC team competencies and reduced external dependency

• Improved project timelines and cost control through optimized design and implementation

• Fewer site errors and delays due to rigorous adherence to quality and compliance
