Tire, İzmir Province, Turkey, located at 38.091 latitude and 27.7334 longitude in the Northern Temperate Zone, offers varying conditions for solar PV energy generation throughout the year. The location demonstrates significant seasonal fluctuations in potential solar electricity production.

Seasonal Solar Production

Solar PV systems in Tire produce their highest output during summer months, generating approximately 8.22kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.13kWh/day, while autumn yields a moderate 4.54kWh/day. Winter shows the lowest production at just 2.52kWh/day per installed kilowatt.

This pattern creates a more than three-fold difference between the best and worst seasons, with summer producing over three times the electricity of winter months. The substantial drop during winter months indicates that while Tire is generally favorable for solar production, the location is not ideal year-round.

Optimal Panel Installation

For fixed solar panel installations in Tire, İzmir Province, the ideal tilt angle to maximize year-round production is 32 degrees facing South. This specific angle optimizes the capture of available sunlight across all seasons, balancing between summer's high production potential and winter's lower yields.

Environmental and Weather Considerations

Several factors could potentially impact solar production in Tire:

• Dust and particulate matter: Tire's location in a semi-arid region means dust accumulation on panels can reduce efficiency by 10-30% if not regularly cleaned.
• High summer temperatures: While summer offers peak production, excessive heat can actually reduce panel efficiency. Panels typically lose efficiency at rates of 0.3-0.5% per degree Celsius above their rated temperature.
• Occasional winter fog: The region experiences some foggy days during winter months, further reducing already diminished winter production.

Preventative Measures

To maximize solar energy production in Tire, İzmir Province, consider implementing these protective measures:

• Install panels with sufficient spacing and elevation to allow natural airflow, reducing heat buildup during summer months.
• Implement a regular cleaning schedule, particularly before summer when production potential is highest.
• Consider a slight adjustment from the ideal 32-degree tilt if winter production is especially important, as a steeper angle can improve winter capture somewhat.
• Use anti-reflective, self-cleaning panel coatings to reduce dust accumulation and maintenance requirements.

Overall, Tire provides good conditions for solar PV installations with excellent summer and spring production, though winter output remains significantly lower even with optimal panel positioning.

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

Seasonal solar PV output for Latitude: 38.091, Longitude: 27.7334 (Tire, 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 32° South in Tire, Turkey

To maximize your solar PV system's energy output in Tire, Turkey (Lat/Long 38.091, 27.7334) throughout the year, you should tilt your panels at an angle of 32° 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 Tire, 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 Tire, Turkey. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° 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	52° 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 Tire, 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 Tire, 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 Tire, Turkey

The terrain around Tire, Turkey features a rich blend of landscapes that reflect the region's geographical position in western Anatolia. Tire sits in the lower reaches of the Küçük Menderes River basin, nestled between mountains and fertile plains. To the north and east, the land gradually rises into the foothills of the Bozdağlar mountain range, with elevations increasing as one moves away from the town center. These northern highlands form a natural boundary that separates the Küçük Menderes basin from neighboring valleys. To the south and west of Tire, the landscape opens into the broader Küçük Menderes plain, characterized by relatively flat agricultural lands that have supported farming for millennia. This alluvial plain, formed by sediments carried by the river system, creates a stark contrast with the more rugged terrain to the north. The transition between these zones features gentle rolling hills dotted with olive groves and fruit orchards that are typical of the Aegean region.

Solar PV Potential Areas

For large-scale solar photovoltaic installations, the gently sloping south-facing hillsides located to the north of Tire present particularly favorable conditions. These areas benefit from optimal sun exposure throughout the day while avoiding the agricultural competition that exists on the fertile valley floor. The elevated terrain between Tire and the higher Bozdağlar mountains offers several advantages: it receives consistent sunlight, experiences less fog than the valley floor, and consists of land less suitable for intensive agriculture. The slightly elevated plateaus extending southwest of Tire toward Selçuk also merit consideration for solar development. These areas combine good solar exposure with proximity to existing infrastructure and transmission networks. The terrain here features moderate slopes that can be easily adapted for panel installation without extensive earthworks. When considering large-scale solar development, it's worth noting that the most fertile sections of the Küçük Menderes plain should likely be preserved for agricultural use, given their historical productivity and importance to local food systems. Instead, the transitional zones between plain and mountain, particularly on south-facing aspects with moderate slopes between 5-15 degrees, represent the optimal balance of solar efficiency and land use considerations. The region's Mediterranean climate, characterized by dry summers and mild, wetter winters, further enhances the area's suitability for solar energy production. The relatively stable atmospheric conditions, particularly during summer months, contribute to consistent energy generation potential throughout much of the year.

Turkey solar PV Stats as a country

Turkey ranks 16th in the world for cumulative solar PV capacity, with 7,817 total MW's of solar PV installed. This means that 5.90% of Turkey's total energy as a country comes from solar PV (that's 14th in the world). 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.
