Solar PV Analysis of Giresun, Turkey
The location at Giresun, Turkey is fairly decent for generating energy via solar panels all year round. However, the amount of electricity produced will vary depending on the season.
In simple terms, a solar panel's job is to convert sunlight into electricity. The more sunlight available, the more electricity can be produced. At this location in Giresun, during summer you can expect each kilowatt (kW) of installed solar power to generate around 6.46 kilowatt-hours (kWh) per day – that's quite good! Spring also provides a good output with 5.21 kWh/day per kW.
However, as expected in autumn and winter when days are shorter and there's less sunlight available, the output drops significantly - down to 3.57 kWh/day per kW in autumn and just 2.40 kWh/day per kW in winter.
One important factor for getting the most out of your solar panels at this particular location is their angle or tilt towards the sun - ideally about 35 degrees pointing southwards would maximize year-round production.
As far as environmental or weather factors go that could potentially impact solar production at this site: it’s situated in northern Turkey which has a climate varying from oceanic to humid subtropical so cloud cover may sometimes reduce availability of direct sunlight; heavy snowfall during winter might cover panels reducing their efficiency; high winds could potentially damage installations if not properly secured.
To counter these potential issues: regular maintenance checks should be done especially after severe weather events; any accumulated snow should be cleared off panels promptly; suitable sturdy mounting systems should be used capable of withstanding local wind conditions; installing adjustable mounts that allow changing panel angles throughout the year might help optimize exposure to sun but they do add extra cost compared to fixed mounts.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 165 locations across Turkey. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Giresun
Seasonal solar PV output for Latitude: 40.8902, Longitude: 38.478 (Giresun, 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 Giresun, Turkey
To maximize your solar PV system's energy output in Giresun, Turkey (Lat/Long 40.8902, 38.478) 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 Giresun, 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 Giresun, 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 | 45° South in Autumn | 56° 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 Giresun, 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 Giresun, Turkey.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Giresun, Turkey
Giresun, Turkey is located on the northern coast of the country along the Black Sea. The topography is characterized by mountainous terrain and high plateaus. The region features a mix of forested areas, agricultural land, and urban development.
The city itself sits at sea level but is surrounded by hills and mountains that reach up to 1,000 meters in altitude. The area's climate is typically humid with significant rainfall throughout the year due to its proximity to the sea.
When considering large-scale solar photovoltaic (PV) installations, factors such as sunlight intensity, land availability and gradient need to be taken into account. Given Giresun's relatively high levels of cloud cover and precipitation due to its coastal location, it may not be an optimal location for solar power generation compared to other regions in Turkey.
However, if we still consider Giresun for solar PV installation then flat agricultural lands or cleared hilltops could potentially be suitable locations for setting up large-scale solar farms. It would also depend on local regulations regarding land use and environmental considerations.
For more precise information about potential sites within this region for large scale PV systems installation you would need a detailed site-specific study that includes data like annual sun hours (solar irradiation), temperature variations etc., which are crucial parameters when planning a solar farm project.
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.
