The location at Acharnes, Attica, Greece is pretty good for generating solar energy throughout the year, but it's not perfect. The best times to generate solar power are during the spring and summer seasons when there's more sunlight available. During these periods, you can expect around 8.05kWh per day in summer and 6.06kWh per day in spring from each kilowatt of installed solar panels.
On the other hand, autumn and winter have less sunlight so they're not as great for generating solar power - you'd only get about 3.62kWh/day in autumn and even less at 2.53kWh/day in winter from each kilowatt of installed panels.
To make the most out of your solar installation throughout the year, it's recommended that you tilt your panels towards south at an angle of about 32 degrees. This will help capture as much sunlight as possible no matter what season it is.
As far as local factors go that might affect how much energy you can produce with your solar panels, Greece generally has a Mediterranean climate with plenty of sunshine throughout most of the year which is beneficial for producing lots of clean renewable energy! However, like any place on earth there could be weather events or environmental factors such as heavy rainstorms or dust storms that could temporarily reduce output by causing shading or dirtying up panel surfaces; but these are typically infrequent and short-lived occurrences.
Preventative measures to ensure greater energy production would include regular cleaning and maintenance checks on your system to keep them free from dirt or debris which can block sunlight reaching your panels; also ensuring a clear unshaded area where you install them (e.g., away from tall trees/buildings) should also help maximize their performance potential all-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 Acharnes
Seasonal solar PV output for Latitude: 38.0832, Longitude: 23.7312 (Acharnes, 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 Acharnes, Greece
To maximize your solar PV system's energy output in Acharnes, Greece (Lat/Long 38.0832, 23.7312) 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 Acharnes, 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 Acharnes, 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 Acharnes, 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 Acharnes, 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 Acharnes, Greece
Acharnes, Greece is located in the Attica region of the country. The topography around Acharnes is characterized by a mix of flat plains and hilly terrains, with several mountain ranges nearby such as Parnitha Mountain to the north and Aigaleo Mountain to the south. The area also features some urban development.
For large-scale solar PV installations, flat open areas are typically ideal as they allow for easier installation and maintenance while maximizing exposure to sunlight. Therefore, any available flat plains in or near Acharnes would be suitable for this purpose. Additionally, south-facing slopes on nearby hills or mountains could also be considered since they would receive significant sunlight throughout the day.
However, it's important to note that other factors should also be taken into consideration when determining suitability for solar PV installations - these include local climate conditions (particularly levels of sunshine), proximity to power grids or demand centers for electricity, land use regulations among others.
Moreover, given that Greece has high solar irradiation levels compared with many other European countries due its Mediterranean climate; this makes it an attractive location generally for solar energy projects.
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.
