Kars, Turkey represents a moderately suitable location for year-round solar PV energy generation, though with significant seasonal variations that potential installers should carefully consider.

Seasonal Solar Performance

The solar energy output at Kars shows dramatic seasonal swings typical of northern temperate locations. Summer months deliver the strongest performance at 7.46kWh per day per kW of installed capacity, making this the prime solar generation period. Spring follows as the second-best season with 6.02kWh daily output per kW, offering excellent conditions for solar energy production. Autumn sees a notable decline to 4.12kWh per day per kW, while winter presents the most challenging conditions with just 2.86kWh daily per kW of installed solar capacity. This winter figure represents less than 40% of summer production, highlighting the location's seasonal dependency.

Optimal Installation Configuration

For maximum year-round solar energy production at Kars, fixed solar panels should be tilted at 35 degrees facing south. This angle has been calculated to optimize total annual output by accounting for the sun's changing elevation throughout the year and weighting for actual solar irradiance conditions.

Environmental and Weather Challenges

Several significant local factors can impede solar production at Kars and require careful consideration during installation planning. Snow accumulation presents the most serious challenge, as Kars experiences harsh winters with substantial snowfall that can completely block solar panels for extended periods. The city's elevation of approximately 1,750 meters above sea level exacerbates winter weather conditions. Snow not only blocks sunlight but adds weight that panels and mounting systems must withstand. Extreme temperature fluctuations between seasons create thermal stress on solar equipment. Winter temperatures can drop well below freezing, while summer heat can be intense, causing expansion and contraction cycles that may affect panel performance and longevity. High winds are common in this elevated plateau location, particularly during winter months, requiring robust mounting systems to prevent damage or displacement of solar installations.

Preventative Installation Measures

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

• Install panels at steeper angles than the calculated optimum (potentially 45-50 degrees) to promote snow shedding, even though this slightly reduces peak summer output
• Use reinforced mounting systems rated for heavy snow loads and high wind speeds typical of the region
• Implement heating elements or anti-icing systems along panel edges to prevent ice dam formation
• Choose panels with strong temperature coefficients that maintain efficiency in extreme cold
• Ensure adequate spacing between panel rows to prevent snow accumulation and shading

Regular maintenance becomes crucial, particularly snow removal during winter months when safe access permits. Installing panels on ground-mounted systems rather than rooftops can facilitate easier snow clearing and maintenance access. The seasonal nature of solar production at Kars makes battery storage systems particularly valuable for maintaining consistent energy supply during the low-production winter months, when output drops to less than half of spring and summer levels.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

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

Seasonal solar PV output for Latitude: 40.6041, Longitude: 43.0912 (Kars, 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 Kars, Turkey

To maximize your solar PV system's energy output in Kars, Turkey (Lat/Long 40.6041, 43.0912) 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 Kars, 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 Kars, 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
24° South in Summer	44° South in Autumn	55° South in Winter	33° 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 Kars, 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 Kars, 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 Kars, Turkey

Topographical Features of the Kars Region

The area surrounding Kars, Turkey presents a distinctive high-altitude landscape characterized by expansive plateaus and gently rolling terrain. This northeastern Turkish city sits at approximately 1,750 meters above sea level on the Kars Plateau, which forms part of the larger Armenian Highland. The topography is predominantly flat to moderately undulating, with wide open spaces that stretch toward distant mountain ranges on the horizon. The immediate vicinity of Kars features relatively gentle slopes and broad valleys that have been shaped by centuries of volcanic activity and glacial processes. The terrain consists mainly of steppe-like grasslands interspersed with agricultural fields, creating a patchwork of open land with minimal tree cover. This sparse vegetation is typical of the semi-arid continental climate that dominates the region. To the south and east of Kars, the landscape gradually rises toward the foothills of the Lesser Caucasus Mountains, while the northern areas maintain the characteristic plateau environment. The region's geology consists primarily of volcanic rocks and sedimentary formations, creating stable ground conditions across much of the area.

Optimal Areas for Large-Scale Solar Development

The expansive plateaus extending southwest and southeast of Kars city center present the most favorable conditions for large-scale solar photovoltaic installations. These areas combine the advantages of relatively flat terrain with minimal existing development, making them ideal candidates for utility-scale projects. The gentle topography in these directions requires minimal grading and site preparation, which helps reduce construction costs and environmental impact. The broad valley systems that radiate outward from Kars offer additional promising locations for solar development. These valleys typically feature stable, well-drained soils and gradual slopes that can accommodate large arrays while maintaining efficient panel orientation. The sparse population density in these rural areas also means fewer conflicts with existing land uses and easier access to transmission infrastructure. Areas to the immediate north and northwest of the city show particular promise due to their combination of flat terrain and proximity to existing electrical grid connections. The open steppe environment in these locations provides unobstructed access to solar radiation throughout the day, while the elevated altitude of the plateau reduces atmospheric interference. The region's stable geological conditions, consisting mainly of consolidated volcanic and sedimentary rocks, provide excellent foundation support for solar mounting systems. This geological stability, combined with the area's low seismic activity, makes the Kars plateau particularly well-suited for long-term solar installations that require minimal ongoing structural maintenance.
