Solar PV Analysis of Elefsina, Greece
Elefsina, Attica, Greece is a reasonably good location for solar energy production year-round, although there are fluctuations in output depending on the season. The best time of year to generate solar power at this location is during the summer when you can expect around 8.05 kilowatt-hours (kWh) of electricity per day for each kilowatt (kW) of installed solar panels. This drops to about 6.06 kWh/day in spring, which is still quite productive.
During autumn and winter, the output decreases significantly due to shorter daylight hours and less intense sunlight. You can expect around 3.62 kWh/day in autumn and only about 2.53 kWh/day during winter months.
To maximize total yearly production from your solar photovoltaic (PV) system at this location, it's recommended that you tilt your panels at an angle of 32 degrees facing South if they are fixed installations.
Several factors could potentially impede solar production in Elefsina; these include weather conditions such as cloud cover or fog which reduce sunlight exposure, dust or debris on the panels blocking light absorption, and potential shading from nearby buildings or trees.
Preventative measures that can be taken when installing a PV system here include choosing a site with minimal shade throughout the day and ensuring regular cleaning maintenance to remove any dust or debris from the panel surface. It may also be beneficial to install tracking systems that allow your panels to follow the sun’s path across the sky for maximum exposure throughout all seasons but especially during those with lower sunlight intensity like autumn and winter.
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 Elefsina
Seasonal solar PV output for Latitude: 38.0363, Longitude: 23.535 (Elefsina, 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 32° South in Elefsina, Greece
To maximize your solar PV system's energy output in Elefsina, Greece (Lat/Long 38.0363, 23.535) 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 Elefsina, 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 Elefsina, Greece. 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 | 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 Elefsina, 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 Elefsina, 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 Elefsina, Greece
Elefsina, Greece is located in the Attica region and lies along the Saronic Gulf. The topography of Elefsina consists of a mix of coastal plains and hilly terrain. It's surrounded by mountains to the north, while the southern part opens up to the sea.
Solar PV facilities require large areas of flat land that receive a lot of sunlight throughout the year. Given this requirement, there are few potential locations around Elefsina that might be suitable for such an installation:
1) Coastal Plains: The coastal plains south of Elefsina could potentially serve as good locations for solar PV installations due to their relatively flat terrain and high levels of sunlight exposure.
2) Mountainous Areas: Some parts on or near mountain slopes could also be used if they face towards the sun (south-facing), but these would likely be more challenging sites due to uneven terrain.
3) Industrial Zones: There are several industrial zones in and around Elefsina which may have available rooftops or unused lands suitable for solar panel installation.
4) Agricultural Land: If local regulations allow it, large agricultural fields could also serve as potential sites for solar farms. However, this would need careful consideration so as not to disrupt local farming practices or ecosystems.
Before any location can be definitively chosen though, site-specific studies including environmental impact assessments would need to be undertaken. Furthermore, factors like proximity to power grids and road accessibility should also be considered when choosing a site.
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.
