We develop solar power plant projects through a rigorous process that includes precise site selection, detailed design, and accurate energy production assessments. Our approach ensures reliable feasibility, compliant permitting, and optimized performance tailored to each project’s unique conditions.
The following steps are generally followed in the selection of the project site:
The point of connection to the electricity grid is determined to define the project’s integration path.
Regions estimated to be high energy potential are identified using mesoscale solar atlases, measurements taken at nearby stations, and production data from operational solar farms.
Preliminary Design and Energy Production Assessment work is carried out using the estimated solar resource and the determined site boundary information. A preliminary feasibility study is carried out, taking into account current market costs, and the project payback period is determined. When conducting the feasibility study, the conditions of the period in which the project can be implemented should also be taken into account as much as possible.
Manufacturers define the basic design requirements to ensure the structural integrity of the construction, solar panels, and inverters. In sites with climatic conditions that meet these requirements, an adequate level of protection against damage from all hazards will be provided throughout the planned service life. The suitability of the equipment for the site must be determined by evaluating the meteorological parameters summarised below.

Layout Design and Energy Production Assessment
Quality control of meteorological data obtained from the Meteonorm 8.1, NASA-SSE, PVGIS TMY, NREL/NSRDB TMY, Solcast TMY, and Solar Anywhere TGY databases is performed to determine the data set that best represents the project site. Using the determined data set, time series with hourly resolution are obtained for parameters such as temperature, humidity, albedo coefficient, wind speed, and radiation.
The PV layout is designed taking into account topographical data and obstacles within the site. Gross energy production is calculated using a construction type suitable for the terrain slopes.
Net energy production is obtained by calculating losses, including near- and far shading. The uncertainty associated with each step of the analysis and the defined losses is calculated. Each uncertainty is combined according to its relationship with the others, and the total uncertainty in the annual energy production estimate and the probability distribution (Probability of exceedence) is calculated.

The calculation steps for the Solar Power Plant Design and Energy Production Assessment are listed below.
The variation in energy production over the 8,760 hours of the year is calculated by following the steps below. The uncertainty in the calculation of hourly energy production is much higher than that in the calculation of annual energy production.
Hourly gross energy production is calculated using the data set determined within the scope of the Energy Production Assessment study.
The net energy production of the power plant is obtained by applying the hourly loss profileses calculated within the same study.
Solar power plant production may be constrained for the reasons summarised below. Losses due to limitations are predicted using hourly energy production.
Environmental and social constraints related to temperature and reflection.

This is specified in the "List of Information and Documents Required for EPDK Preliminary Licence and Licence Applications". These documents are submitted to the institution in a complete manner, with the necessary work carried out and document approvals obtained.
The site boundary is established in accordance with the "Technical Assessment Regulation" published by EIGM, using the GES layout or solar potential maps created for the project site.
During the completion of construction permits for GES projects, opinions must be obtained from the relevant institutions. uSens prepares the application files and shares the document tracking numbers with the Employer after submitting them to the institutions. Upon request, the status of applications is monitored monthly, and after opinions are obtained from all institutions, a summary of the restriction status is shared with the Employer.
