Edirne, Turkey, located in the Northern Temperate Zone, presents a moderately favorable location for solar PV energy generation, though with significant seasonal variations that potential solar installers should carefully consider.

Seasonal Solar Performance

The location experiences substantial fluctuations in solar energy output throughout the year. Summer delivers the strongest performance at 7.38kWh per day per kW of installed capacity, making it an excellent season for solar generation. Spring follows as the second-best performing season with 5.35kWh per day per kW, offering solid energy production during the warmer months. However, the colder seasons present notable challenges. Autumn drops significantly to 3.30kWh per day per kW, while winter reaches the lowest output at just 2.12kWh per day per kW. This winter figure represents less than 30% of summer production, indicating that solar systems in Edirne will generate most of their annual energy during the warmer half of the year.

Optimal Installation Configuration

For fixed panel installations at this location, the ideal angle to tilt panels to maximize total year-round production is 35 degrees facing South. This calculation accounts for the Earth's elliptical orbit and weights the angles by daily photovoltaic potential using solar irradiance data to determine the optimal annual average position.

Environmental and Weather Factors

Several local factors in Edirne could potentially impact solar energy production:

• Snow accumulation: Winter weather may cause snow to collect on panels, blocking sunlight and reducing already low winter output
• Dust and particulate matter: The region's continental climate and agricultural activities can lead to dust buildup on panel surfaces
• Temperature effects: Hot summer temperatures can reduce panel efficiency despite high solar irradiance
• Humidity and condensation: Seasonal weather patterns may cause moisture-related efficiency losses

Preventative Measures

To maximize energy production despite these challenges, several installation strategies prove beneficial:

• Steeper tilt angles: The recommended 35-degree tilt helps snow slide off panels naturally during winter months
• Regular cleaning schedules: Implementing quarterly cleaning routines, particularly before peak seasons, maintains optimal light transmission
• Adequate ventilation: Ensuring proper airflow behind panels helps manage heat buildup during hot summers
• Quality mounting systems: Using corrosion-resistant materials suitable for the local climate extends system lifespan
• Monitoring systems: Installing performance monitoring helps identify when cleaning or maintenance is needed

Overall, while Edirne offers reasonable solar potential, particularly during spring and summer months, the significant seasonal variation and potential weather-related challenges require careful system design and maintenance planning to achieve optimal performance.

Solar output per kW of installed solar PV by season in Edirne

Seasonal solar PV output for Latitude: 41.6767, Longitude: 26.5944 (Edirne, Turkey), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 35° South in Edirne, Turkey

To maximize your solar PV system's energy output in Edirne, Turkey (Lat/Long 41.6767, 26.5944) throughout the year, you should tilt your panels at an angle of 35° South for fixed panel installations.

As the Earth revolves around the Sun each year, the maximum angle of elevation of the Sun varies by +/- 23.45 degrees from its equinox elevation angle for a particular latitude. Finding the exact optimal angle to maximise solar PV production throughout the year can be challenging, but with careful consideration of historical solar energy and meteorological data for a certain location, it can be done precisely.

We use our own calculation, which incorporates NASA solar and meteorological data for the exact Lat/Long coordinates, to determine the ideal tilt angle of a solar panel that will yield maximum annual solar output. We calculate the optimal angle for each day of the year, taking into account its contribution to the yearly total PV potential at that specific location.

Seasonally adjusted solar panel tilt angles for Edirne, Turkey

If you can adjust the tilt angle of your solar PV panels, please refer to the seasonal tilt angles below for optimal solar energy production in Edirne, Turkey. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 35° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
26° South in Summer	45° South in Autumn	56° South in Winter	34° South in Spring

Our recommendations take into account more than just latitude and Earth's position in its elliptical orbit around the Sun. We also incorporate historical solar and meteorological data from NASA's Prediction of Worldwide Energy Resources (POWER) API to assign a weight to each ideal angle for each day based on its historical contribution to overall solar PV potential during a specific season.

This approach allows us to provide much more accurate recommendations than relying solely on latitude, as it considers unique weather conditions in different locations sharing the same latitude worldwide.

Calculate solar panel row spacing in Edirne, Turkey

We've added a feature to calculate minimum solar panel row spacing by location. Enter your panel size and orientation below to get the minimum spacing in Edirne, Turkey.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. Minimum Spacing:
   We add the shadow length to the horizontal space occupied by tilted panels.

This approach ensures maximum space efficiency while avoiding shading during critical times, as the Winter solstice represents the worst-case scenario for shadow length.

Topography for solar PV around Edirne, Turkey

Topographical Features Around Edirne

The landscape surrounding Edirne in northwestern Turkey presents a predominantly flat to gently rolling terrain characteristic of the Thrace region. This area sits within the European portion of Turkey, where the topography consists mainly of low-lying plains and modest hills that rarely exceed 200 meters in elevation. The city itself rests at approximately 50 meters above sea level, positioned strategically where the Tunca and Maritsa rivers converge. The region features expansive agricultural plains that stretch in multiple directions from the city center, with the terrain gradually undulating rather than presenting steep gradients. These plains are interspersed with gentle ridges and shallow valleys that have been shaped by centuries of river activity and agricultural development. The Maritsa River valley creates a natural corridor through the landscape, with fertile alluvial soils deposited across much of the surrounding area. To the south and east of Edirne, the terrain begins a gradual ascent toward the more mountainous regions of inland Turkey, but this transition occurs over considerable distances. The immediate vicinity maintains its relatively level character, making it well-suited to various forms of development and land use.

Optimal Areas for Large-Scale Solar Development

The flat to gently rolling topography around Edirne creates favorable conditions for large-scale solar photovoltaic installations. The most promising areas lie to the south and southeast of the city, where extensive plains offer minimal topographical obstacles and good accessibility via existing road networks. The agricultural plains extending toward the villages of Karaağaç and beyond present ideal characteristics for solar development, with their level terrain requiring minimal grading or site preparation. These areas benefit from unobstructed southern exposures and sufficient distance from urban development to accommodate large installations without land use conflicts. Areas to the west and northwest of Edirne also show potential, particularly the flatter sections of the Maritsa River valley. The gentle slopes in these regions can be advantageous for solar panel positioning while maintaining cost-effective installation procedures. The proximity to existing electrical infrastructure along major transportation corridors adds to the appeal of these locations. The slightly elevated areas to the north of the city, while still relatively flat, offer additional advantages through improved drainage and reduced risk of seasonal flooding that can occasionally affect lower-lying areas near the river systems. These elevated plains maintain the accessibility and installation benefits of flatter terrain while providing natural protection from water-related issues. Agricultural zones that are transitioning away from active farming present particularly attractive opportunities, as the existing land use patterns and access roads can often be adapted for solar installations with minimal additional infrastructure investment.
