EPC
EPC Construction, Electromechanical Assembly and Photovoltaic Civil Works
We carry out the comprehensive construction of solar projects (On-Grid, Off-Grid, and BESS) under schemes EPC (Engineering, Procurement and Construction) or BoP (Balance of Plant), ensuring regulatory compliance (RETIE, NTC 2050) and zero deviations in timelines or budgets.
1. Construction Services Portfolio
Civil Works and Infrastructure:
- Precision surveying, earthmoving, and land preparation.
- Pull-Out tests (Pull-Out tests) and driving of fixed structures or solar trackers (trackers single-point/two-point).
- Construction of foundation slabs for centralized inverters, transformation centers (Skid/Container), and BESS containers.
- Excavation and execution of trenches, ducts, and underground conduits for DC and AC circuits in medium and low voltage.
- Precision surveying, earthmoving, and land preparation.
Electromechanical Assembly and Connection:
- Mechanical assembly of TOPCon/Bifacial modules with calibrated torque wrench to ensure tightening torques according to manufacturer.
- Laying and combing of solar wiring (H1Z2Z2-K), certified MC4/Evo2 connection, and hydraulic crimping of power terminals.
- Integration of combiner boxes (Combiner Boxes), AC/DC protection panels, string or centralized inverters.
- Mechanical assembly of TOPCon/Bifacial modules with calibrated torque wrench to ensure tightening torques according to manufacturer.
Substations and Evacuation Lines:
- Installation of medium voltage cells, power transformers, and grounding systems (SPAT) with equipotential mesh.
- Construction and interconnection of overhead or underground evacuation lines up to the Network Operator's coupling point.
- Installation of medium voltage cells, power transformers, and grounding systems (SPAT) with equipotential mesh.
Commissioning Tests (Commissioning & SAT):
- Conductor insulation tests (Megger), ground mesh continuity, and insulation resistance measurement in DC chains.
- Thermographic inspection under load and progressive energization tests pre-certification RETIE.
- Conductor insulation tests (Megger), ground mesh continuity, and insulation resistance measurement in DC chains.
2. Differential Construction Matrix
| Construction Phase | Conventional Installer | EPC Construction ISOEN (Pro Mode) | Direct Impact on the Plant |
| Foundation and Structure | Empirical driving without prior geotechnical studies | Load studies and Pull-Out tests on site prior to installation | Elimination of structural deformations due to wind or earthquakes |
| Electromechanical Connection | Generic manual crimping without torque control | Calibrated hydraulic tools and Tier-1 brand IP68 connectors | 95% reduction in the risk of electric arcs and hotspots |
| Safety and Regulations | Basic compliance with protection elements | Dedicated HSE supervision on site and pre-RETIE quality protocol | Zero workplace accidents and certification without technical findings |
"80% of operational failures during the lifespan of a photovoltaic system originate from poor practices in the construction phase. Our rigor in electromechanical execution protects the assets, guarantees the project's bankability, and ensures continuous operation for over 25 years."
