Afyonkarahisar, Turkey, located at 38.6768° N, 30.6444° E, presents a relatively favorable location for solar PV energy generation throughout the year. This city in the Northern Temperate Zone experiences significant seasonal variations in solar energy production, with peak performance during the summer months.

Seasonal Solar Energy Production

The solar energy output in Afyonkarahisar varies considerably across seasons. Summer yields the highest production at 7.91 kWh per day for each kilowatt of installed solar capacity. Spring follows with 5.98 kWh/day, then autumn with 4.48 kWh/day. Winter sees the lowest output at 2.56 kWh/day per kW installed.

The most ideal time for solar energy generation in Afyonkarahisar is from late spring through early autumn. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency and energy production.

Optimal Panel Tilt

For fixed panel installations in Afyonkarahisar, the ideal tilt angle to maximize year-round solar production is 33 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the seasonal variations in the sun's position.

Environmental and Weather Factors

While Afyonkarahisar generally offers good conditions for solar energy production, there are some factors that could potentially impact efficiency:

• Dust and air pollution: The region's semi-arid climate can lead to dust accumulation on panels, reducing their efficiency.
• Snow in winter: Although not frequent, occasional snowfall could temporarily decrease energy production.

To mitigate these issues, regular cleaning of solar panels is recommended, especially during drier months. Installing panels at the optimal angle also helps with natural cleaning from rainwater and reduces snow accumulation. Additionally, using high-quality, dust-resistant panels can help maintain efficiency in dusty conditions.

Overall, while Afyonkarahisar experiences seasonal variations in solar energy production, its location in the Northern Temperate Zone provides a good balance for year-round solar PV generation, with proper installation and maintenance practices.

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 Afyonkarahisar

Seasonal solar PV output for Latitude: 38.6768, Longitude: 30.6444 (Afyonkarahisar, 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 33° South in Afyonkarahisar, Turkey

To maximize your solar PV system's energy output in Afyonkarahisar, Turkey (Lat/Long 38.6768, 30.6444) throughout the year, you should tilt your panels at an angle of 33° 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 Afyonkarahisar, 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 Afyonkarahisar, Turkey. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
23° South in Summer	43° South in Autumn	53° South in Winter	31° 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 Afyonkarahisar, 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 Afyonkarahisar, 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 Afyonkarahisar, Turkey

Afyonkarahisar, located in western Turkey, is situated in a diverse topographical region characterized by a mix of plains, hills, and mountains. The city itself is nestled at the foot of a steep rocky hill, which is crowned by an ancient castle. This distinctive feature gives Afyonkarahisar its name, which translates to "Opium Black Castle" in Turkish. The surrounding landscape is dominated by the Anatolian Plateau, a vast expanse of relatively flat terrain that stretches across much of central Turkey. To the east and northeast of Afyonkarahisar, the land gradually rises into the more rugged terrain of the Emirdağ Mountains. These mountains, part of the larger Taurus Mountain range, create a picturesque backdrop to the region. To the west and southwest of the city, the topography transitions into a series of rolling hills and valleys. This area is known for its fertile soil and is extensively used for agriculture, particularly the cultivation of crops such as sugar beets, cereals, and the famous Afyon poppy.

Potential for Large-Scale Solar PV

When considering areas suitable for large-scale solar photovoltaic (PV) installations near Afyonkarahisar, several factors come into play. The most promising locations would likely be found in the expansive plains to the south and southeast of the city. These areas offer several advantages for solar energy development: Firstly, the relatively flat terrain of the Anatolian Plateau provides ample space for the installation of large solar arrays without the need for extensive land preparation. The open nature of these plains also means there are fewer obstacles that could cast shadows on the solar panels, maximizing their exposure to sunlight throughout the day. Secondly, this region of Turkey experiences a continental climate with hot, dry summers and cold winters. The abundance of clear, sunny days, particularly during the summer months, makes it ideal for solar energy generation. Additionally, the areas to the south of Afyonkarahisar, stretching towards the city of Dinar, have lower population densities and less intensive agricultural use. This could make it easier to acquire large tracts of land for solar farm development without significantly impacting local communities or food production. However, it's important to note that any large-scale solar PV project would require detailed environmental and grid connectivity assessments. The proximity to existing power infrastructure and the capacity of the local grid to accommodate large influxes of solar-generated electricity would be crucial factors in determining the most suitable locations for such developments.
