EPC (Engineering – Procurement – Construction)

All phases—from site selection to realization and commissioning of the project—are performed with exhaustive care. Services such as initiation and follow-up on all official permitting required for project realization and installation tests are carried out successfully.

Site Selection

Solar Potential Status

When selecting a site for solar power plants, a primary requirement is the solar potential. The more solar radiation is present in the city where the power plant will be constructed, the more energy can be generated.

Site’s Soil Structure

The construction site’s topographic structure is critical. Initial budget costs may change if the project requires extra earthworks for rocky structures or subsequent construction phases.

Site’s Shading Status

Site surroundings should be surveyed during the site selection process. Any formation that might cast a shadow on the site will reduce the solar power plant’s yield (i.e. tall trees, buildings, mountains, etc.). If any high-voltage transmission line are over or near the site, they will also have an unfavorable effect on your panels and energy productivity.

Site’s Contamination and Powdering Status

Site status for a future power plant should be analyzed for powder content near or around the area, whether from a concrete plant, stone quarry, or sand quarry. These powders will be carried by the winds onto your solar panels and contaminate them, requiring frequently cleaning to avoid substantially decreased productivity.

Site’s Connection with Energy Transmission Line

Solar power plant installation requires it to be connected to energy transmission line at a point designated by the energy distribution company. These transmission routes must be detailed and analyzed.

Site’s Convenient Weather Conditions

The site region is critical for solar power plant installation. One must determine the sunny, foggy, rainy, and snowy conditions of the site location, plus obtain the meteorological data for the next year.

Site’s Transportation Status

Transportation is a major consideration. If accessing the site is a challenge, labor and transportation costs will be high in the initial investment. Recognize that some problems might arise in the transportation of solar panels, construction teams, and equipment such as transformer box due to site location and conditions.



Obtainment of all necessary permits and approval of the project are followed by initiation of the project installation phase. This part is one of the most important part of solar energy EPC process. The first of all consideration points here is to pay attention to the site structure.

(In case of elevations or hollows in the site structure, this will lead to extra excavation costs.) Before commencement of Solar Power Plant installation, site grading works are performed basing on the site structure. Upon completion of the site grading works, the respective site is enclosed with a wire fence. Then; the construction system, on which the photovoltaic modules will be assembled, is required to be placed basing on the approved project.

Assembly of photovoltaic (PV) modules is followed by performance of DC cabling works in line with the approved project. Once the inverters and collection boards are installed, AC cabling works are performed, and they are connected to the substation. Upon completion of all connections to the substation, the system is connected to the main connection system.

Project Design and Installation of Energy Transmission Lines

It refers to the project design, approval and installation phase for project design of all underground cables and overhead line projects to be connected to the system in accordance with the call for letter under the respective connection agreement.

Testing and Commissioning

Pre-commissioning on-site tests of all equipment, which have been installed in line with the project, are conducted by our team members of expert engineers and technical field team by means of the hi-tech devices.
The project and site conformity is subjected to all necessary tests and controls, and the commissioning processes are completed, which lead to operations of the system.

Design and Installation of Substation and Distribution Center

It refers to the design, project design and installation phase of the Distribution Center, KOK (Circuit-Breaker Measuring Cabinet) and Substation specified in the call for letter under the respective connection agreement.

Technical and Economic Feasibility Studies

Economic and commercial feasibility studies are not depending on only the technical performance but also the investment, operations and maintenance costs of the project. With the aim of surveying the productivity of different solar power plants, the initial field survey and design, determining the technical parameters to be reflected on the PVSyst simulation to find out the approximate energy output, is carried out. The energy output will be incorporated into the financial analyses.
