We carry out the technical and financial pre-assessment studies and report, in measurable terms, the risks affecting the plant’s lifetime and performance. The decision is yours; the verified data is ours.
It’s time to build a solar power plant and generate your own electricity. In this process, with our owner’s engineering service, we technically manage the entire process for you and help you get the best out of the facility you will build. You can find our technical engineering service scope for SPPs below. If you have any questions about our scope of services, you can contact us here.

The project’s design documents are reviewed against the requirements of IEC 62548 and IEC 62446-1: string sizing, maximum system voltage and current limits, cable cross-sections and voltage drop, protection coordination and the earthing arrangement are verified. The shading and loss assumptions used in the design are confirmed against the actual site conditions, including rooftop obstacles (chimneys, lighting, etc.) and geographic obstacles (hills, trees, etc.). The meteorological data set and calculation method used in the yield analysis are reviewed independently, and whether the declared production figures are substantiated is reported.
Construction period engineering services cover the planning and supervision of the processes that will take place during the investor company’s solar power plant investment and the commissioning of the power plant. In this way, it is aimed to minimize the risks and prevent possible problems that may occur in the long term. It also aims to take measures to protect the rights of the investor for possible legal processes.
After at least 6 months of operation of the facility, a site visit is made and visual and electrical controls are carried out according to the standards. At the same time, performance measurements of the equipment are made and it is reported to the investor whether the conditions guaranteed by the manufacturer are met. Visual inspections check for physical defects, while electrical tests check production performance.
Once the plant is in production, radiation data, production data and temperature data are processed and the overall efficiency of the system is calculated. With this calculation, the performance of the system is revealed. In the subsequent controls, degradation is also based on this data. This is a necessary data set to track any project-wide problem or excessive degradation of cells.

After the selection of the EPC, the projects to be drawn by the EPC are controlled and approved by us, and the approval of the projects by the EPC to the relevant institutions is supervised.

The most important equipment used in solar power plants is the solar panel. For this reason, it is important that its production is realized in accordance with the standards. Production controls of solar panels are carried out in two stages. At the first stage, product certification control is carried out. Factory inspections are then carried out during the production process.
Regular on-site project audits are carried out for the healthy progress of the project from inception to acceptance. In this process, project progress is monitored according to the contract. Regular project visits are carried out during construction. According to the requirements of the EPC contract, construction and project progress is monitored in line with the planned schedule.
Quality controls are carried out during the production of incoming materials for the SPP plant and after shipment to the site.
All construction and assembly works are carried out in a controlled manner, as any mistake in the assembly part may become irreversible in the future. The process is regularly reported and recorded from start to finish.
In order to monitor and measure the performance of solar power plants, it is necessary to perform tests within the scope of IEC 62446 and IEC 60891. These tests are mainly IV-Curve (current-voltage) measurement, thermal tests, insulation test, grounding test and performance measurement. After the solar power plant is installed, these tests are carried out and it is analyzed whether the plant performs as expected. You can find a detailed description of the tests here. A report containing all the tests is prepared. This report is also a risk table. According to the report, the findings are prioritized and presented to the EPC company. The findings are reported to the investor in order of priority.

We provide independent inspection and verification services throughout the process, from system design to operation. Please contact us for information about our owner’s engineering service.
Our inspection and verification reports can be used by investors as evidence in technical due diligence, financing applications and plant acquisition assessments.
Solarian is a Type A inspection body accredited by TÜRKAK under ISO/IEC 17020 (AB-0649-M). Accredited inspections are those within the scope stated on the certificate. Scope of accreditation
We review the technical and commercial interfaces that influence project cost, performance, and allocation of risk.
We assess the EPC contract without a commercial interest in its execution or outcome.
Our review focuses on recurring issues in scope, liquidated damages, guarantees, warranties, and technical responsibilities.
Findings are documented so that investors, lenders, boards, and advisers can evaluate the identified risks.
