Solar PV Analysis of Voula, Greece
The location at Voula, Attica, Greece is fairly good for generating energy via solar PV year-round. The amount of electricity you can expect to get from each kW of installed solar varies by season. In summer, you can expect about 8.19 kWh per day; in autumn, about 4.13 kWh per day; in winter, about 2.88 kWh per day; and in spring, about 6.39 kWh per day.
The most ideal time to generate solar at this location would be during the summer months when sunlight hours are longest and the sun is at its highest point in the sky resulting in more direct sunlight hitting the panels for longer periods of time.
If you're installing a fixed panel installation here, it's best to tilt your panels at an angle of around 32 degrees towards south direction for maximum year-round production as it aligns with the path of the sun across the sky throughout different seasons.
As for local factors that could affect solar production - Voula is located near mountains which could potentially block some sunlight depending on where exactly your installation is situated. Also typical weather patterns should be considered such as seasonal cloud cover or fog which might reduce sunlight availability especially during winter months when days are shorter and less direct sunlight reaches ground level.
In order to overcome these potential issues: carefully consider placement of your panels to avoid shading from nearby structures or landscape features like trees or mountains; monitor local weather patterns and adjust accordingly if possible (for example if there's usually heavy fog early morning then having a battery storage system would allow storing excess energy produced during peak sunshine hours); regular cleaning and maintenance will also ensure optimal performance by removing any dust or debris that might accumulate on panel surfaces over time reducing their efficiency.
So overall while there may be some challenges due to environmental factors but with careful planning and management these can be mitigated ensuring effective use of solar power all year round at this location.
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 Voula
Seasonal solar PV output for Latitude: 37.8522, Longitude: 23.7768 (Voula, 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 Voula, Greece
To maximize your solar PV system's energy output in Voula, Greece (Lat/Long 37.8522, 23.7768) 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 Voula, 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 Voula, 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 | 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 Voula, 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 Voula, 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 Voula, Greece
Voula, Greece is located in the southern part of the Attica region, along the Saronic Gulf. The topography of this area is characterized by a mix of coastal plains and hilly terrain. The coastal areas are relatively flat with sandy beaches while the inland areas feature rolling hills and low mountains.
Regarding solar PV installations, flat areas are generally more suitable as they require less site preparation work such as leveling. However, hilly or mountainous locations can also be used if proper terracing is done or if solar trackers are used to optimize sun exposure.
In terms of specific locations around Voula for large-scale solar PV installation:
1. Coastal Plains: These could be ideal due to their relative flatness but one must consider proximity to residential areas and potential impact on local ecosystems.
2. Inland Flat Areas: There may be agricultural lands that could potentially accommodate dual-use (agrivoltaics), where farming and solar power production coexist.
3. Rooftops: Large buildings such as warehouses or factories can also host rooftop installations.
However, it's important to note that suitability for large-scale solar PV isn't just about topography; factors such as sunlight hours (solar irradiance), local climate conditions, land use restrictions and grid connectivity should also be taken into account.
Given Greece's high annual sunshine duration (one of the highest in Europe) and government incentives for renewable energy sources, there's significant potential for expanding solar energy generation in regions like Voula.
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.
