Van, Turkey presents a moderately favorable location for solar PV energy generation, though with notable seasonal variations that impact year-round viability.

Seasonal Solar Performance

The solar energy output at Van varies significantly throughout the year. Summer provides the strongest performance at 8.55 kWh per day per kW of installed capacity, making it an excellent season for solar generation. Spring offers good production levels at 6.48 kWh per day per kW, representing the second-best period for energy generation. Autumn sees a notable decline to 4.79 kWh per day per kW, while winter presents the most challenging conditions with only 3.20 kWh per day per kW of output. This winter performance represents less than 40% of summer production levels, indicating substantial seasonal dependence.

Optimal Installation Configuration

For fixed panel installations at Van, the ideal tilt angle is 33 degrees facing south to maximize total year-round production. This angle has been calculated to optimize solar output across all seasons by accounting for the sun's varying position throughout the year and weighting for daily solar potential.

Environmental and Weather Challenges

Van's location in eastern Turkey presents several environmental factors that can significantly impact solar production:

• Heavy snowfall during winter months can cover panels and drastically reduce output
• Dust storms from nearby arid regions can accumulate on panel surfaces
• High altitude location (approximately 1,750 meters above sea level) creates extreme temperature variations
• Frequent cloud cover during autumn and winter reduces solar irradiance

Preventative Measures for Enhanced Production

Several installation strategies can help mitigate these challenges and improve energy output:

• Install panels at steeper angles (40-45 degrees) to promote natural snow shedding
• Implement automated cleaning systems or schedule regular manual cleaning to remove dust accumulation
• Use mounting systems with adequate ventilation to prevent overheating during summer
• Consider tracking systems that can adjust panel angles seasonally to optimize winter performance
• Install panels with anti-reflective coatings designed for high-altitude conditions

Regular maintenance becomes particularly important at this location, with monthly cleaning recommended during dusty periods and immediate snow removal after winter storms to maintain optimal performance.

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 Van

Seasonal solar PV output for Latitude: 38.5142, Longitude: 43.3132 (Van, 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 Van, Turkey

To maximize your solar PV system's energy output in Van, Turkey (Lat/Long 38.5142, 43.3132) 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 Van, 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 Van, 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
22° South in Summer	42° South in Autumn	53° South in Winter	30° 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 Van, 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 Van, 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 Van, Turkey

Topography Around Van, Turkey

Van sits in eastern Turkey at an elevation of approximately 1,750 meters above sea level, positioned on the eastern shore of Lake Van, the country's largest lake. The city is nestled within a broad valley surrounded by dramatic mountainous terrain that defines much of the regional landscape. The immediate area around Van features relatively flat to gently rolling terrain near the lakeshore, which gradually transitions into steeper slopes as the distance from the lake increases.

Lake Van itself dominates the local geography, stretching approximately 120 kilometers from east to west and covering an area of about 3,750 square kilometers. This massive body of water creates a moderating influence on the local climate and provides a significant flat water surface, though obviously unsuitable for ground-mounted solar installations. The lake sits in an endorheic basin, meaning it has no natural outlet to the sea.

The surrounding mountain ranges include the Nemrut volcanic cone to the west, which rises to over 3,000 meters, and various other peaks that form part of the Armenian Highland. These mountains create a complex topographical pattern of valleys, plateaus, and steep-sided ridges radiating outward from the central lake basin. The volcanic nature of much of the terrain has created both opportunities and challenges for development, with some areas featuring relatively stable volcanic plateaus while others present more rugged, broken topography.

Optimal Areas for Large-Scale Solar Development

The most promising locations for large-scale solar photovoltaic installations around Van would be the extensive flat to gently sloping areas that extend eastward and southward from the city. These zones offer several kilometers of relatively level terrain with minimal slope variations, making them ideal for utility-scale solar farms. The eastern plains, in particular, provide substantial open areas with good accessibility for construction and maintenance vehicles.

The southern approaches to Van also present excellent opportunities, where the terrain gradually rises from the lakeshore in broad, gentle slopes before becoming steeper at higher elevations. These southern areas benefit from unobstructed southern exposure, which is crucial for maximizing solar panel efficiency. The gradual elevation changes in this direction can actually be advantageous, as slight south-facing slopes can improve solar collection compared to completely flat terrain.

Areas to the north and northeast of Van offer additional suitable terrain, particularly where the landscape consists of broad plateau areas before the terrain becomes more mountainous. These elevated plateaus often provide excellent wind circulation for cooling solar panels and typically have fewer obstacles that might create shading issues. The key advantage of these locations is their distance from the more densely populated areas while still maintaining reasonable proximity to existing electrical infrastructure.

The western areas near Van are generally less suitable due to the proximity of Lake Van itself and the more irregular volcanic terrain associated with Mount Nemrut. However, some elevated areas to the northwest could potentially work for smaller installations where the terrain permits. The primary considerations for any location would be avoiding areas prone to seasonal flooding, ensuring stable ground conditions for mounting systems, and maintaining access to transportation routes for equipment delivery and maintenance activities.

Each year Turkey is generating 92 Watts from solar PV per capita (Turkey ranks 41st in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Turkey?

Yes, there are incentives for businesses wanting to install solar energy in Turkey. The Turkish government offers a number of financial incentives and tax breaks for businesses that invest in renewable energy sources such as solar power. These include grants, loans, and tax credits. Additionally, the government has set up a feed-in tariff system which guarantees a certain price per kilowatt hour of electricity generated from solar panels. This helps to make investing in solar energy more attractive to businesses.
