A solar power plant investment, when not designed correctly, can turn into one that falls short of expected production and stalls in approval processes. The SPP design service covers the full engineering need of rooftop, ground-mounted, or self-consumption solar plants, from feasibility to commissioning. The goal is for the investor to hold a design file that is complete both technically and administratively, and ready for approval.
Miratek runs this process on a turnkey, single-point-of-contact model. Site survey, shading and yield analysis, preparation of the electrical designs, follow-up of the TEDAŞ approval process, and commissioning all proceed under the responsibility of the same team. The investor thus tracks the process from a single point without carrying the burden of coordinating multiple disciplines.
During design, module layout, inverter selection, the LV and MV connection scheme, and protection coordination are addressed together. This holistic approach ensures the plant both meets the grid connection criteria and runs efficiently through its operating life.

How We Work
Site Survey and Feasibility
The site or rooftop is examined in place; layout, shading, and connection options are assessed and a yield simulation is prepared.
Design
Electrical designs covering module layout, inverter selection, the single-line diagram, and protection coordination are prepared.
Approval Process Management
Design approval and connection processes before TEDAŞ and the relevant distribution company are followed up.
Procurement and Installation
Equipment matching the approved design is procured; structure, module, and panel installation is carried out with site discipline.
Testing and Commissioning
Insulation, grounding, and functional tests are completed; the system is commissioned in synchronization with the grid.
Acceptance and Monitoring
Provisional acceptance procedures are handled; remote monitoring infrastructure is set up and the plant is handed over to operation.

- Preparation of LV and MV electrical designs
- Management of TEDAŞ design approval and connection processes
- Module, inverter, and panel selection with technical specification drafting

Frequently Asked Questions
Which permits are required for a rooftop SPP installation?
For unlicensed self-consumption systems, an application is filed with the local distribution company and design approval is obtained. The process consists of the application file, design approval, and acceptance stages. Miratek carries out all of these steps on the investor's behalf.
How quickly does an SPP investment pay for itself?
The payback period depends on the facility's consumption profile, installed capacity, and current electricity tariffs. At the feasibility stage, the annual yield simulation and consumption data are evaluated together to produce a payback calculation specific to the investment.
Is our existing transformer capacity sufficient for the SPP connection?
Connection capacity is assessed against the facility's existing connection agreement and transformer rating. This check is done at the survey stage; if needed, a transformer uprating or connection revision is also brought into the project scope.
