Solar PV Analysis of Alexandroupoli, Greece
The location at Alexandroupoli, East Macedonia and Thrace, Greece is quite good for generating energy via solar photovoltaic (PV) systems year-round, although it's not perfect. This is because the amount of electricity you can generate with a solar PV system depends on how much sunlight hits your panels - and this varies by season.
In summer, when days are longest and sunniest, each kilowatt of installed solar could produce around 7.94 kilowatt-hours per day. In spring, the output drops to about 5.81 kilowatt-hours per day due to shorter days and less intense sunlight.
Autumn sees further drop in production to roughly 3.77 kilowatt-hours per day as days get even shorter and the sun's rays become less direct. Winter has the lowest output at about 2.30 kilowatt-hours per day because of short daylight hours and often cloudy weather.
To maximize yearly energy production from a fixed panel installation at this location, it would be best to tilt panels towards South at an angle of 34 degrees.
However, there might be local factors that could affect solar production in Alexandroupoli significantly such as periods of heavy cloud cover or high levels of dust in the air which can block sunlight from reaching your panels effectively.
Preventative measures can include regular cleaning of your solar panels especially during dusty seasons or after storms; installing tracking systems that allow your panels to follow the path of the sun across the sky throughout each day; or using more efficient types of solar cells that perform better under lower light conditions.
It's also important to consider potential shading issues from nearby buildings or trees when choosing where exactly on your property you install your system – ideally you want them somewhere where they'll get unobstructed sunlight all year round if possible.
Overall though - while not perfect - Alexandroupoli is still a pretty decent place for generating power through solar PV systems year-round.
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 87 locations across Greece. 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 Alexandroupoli
Seasonal solar PV output for Latitude: 40.8409, Longitude: 25.8737 (Alexandroupoli, Greece), 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 34° South in Alexandroupoli, Greece
To maximize your solar PV system's energy output in Alexandroupoli, Greece (Lat/Long 40.8409, 25.8737) throughout the year, you should tilt your panels at an angle of 34° 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 Alexandroupoli, Greece
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 Alexandroupoli, Greece. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 25° 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 Alexandroupoli, Greece
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 Alexandroupoli, Greece.
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 Alexandroupoli, Greece
Alexandroupoli, Greece is located in the region of East Macedonia and Thrace. The area is characterized by a mix of flatlands and hilly terrain, with the Rhodope Mountains to the north. It's located near the coast of the Aegean Sea, providing it with a Mediterranean climate that includes hot, dry summers and mild winters.
The best areas for large-scale solar PV installations would be on relatively flat or gently sloping land, which allows for easier installation and better sun exposure. In Alexandroupoli's case, this could potentially include coastal areas where there may be less shading from mountains or buildings.
However, several factors need to be taken into account when selecting sites for solar farms such as local climate conditions (solar irradiance), proximity to power grids for energy transmission, potential environmental impacts (e.g., on local ecosystems or agricultural land use), legal restrictions etc.
In terms of solar irradiance - Alexandroupoli has good potential due to its southern location and high number of sunny days throughout the year.
Overall feasibility should be determined through detailed site-specific studies undertaken by professionals in renewable energy development.
Greece solar PV Stats as a country
Greece ranks 24th in the world for cumulative solar PV capacity, with 3,530 total MW's of solar PV installed. This means that 9.30% of Greece's total energy as a country comes from solar PV (that's 4th in the world). Each year Greece is generating 329 Watts from solar PV per capita (Greece ranks 11th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Greece?
Yes, there are incentives for businesses wanting to install solar energy in Greece. The Greek government offers a range of financial incentives and tax breaks for businesses that invest in renewable energy sources such as solar power. These include grants, subsidies, and tax credits. Additionally, the European Union has set up a number of programs to support the development of renewable energy sources in Greece.
