Solar PV Analysis of Aigio, Greece
Aigio, West Greece, Greece, situated at latitude 38.2516 and longitude 22.0825, offers a promising location for solar PV energy generation. This Northern Temperate Zone city experiences significant seasonal variations in solar energy production, which is typical for its latitude.
Seasonal Solar Performance
Solar panels in Aigio demonstrate peak performance during the summer months, producing an impressive 7.92 kWh per day for each kilowatt of installed capacity. Spring follows closely, with a daily output of 6.18 kWh/kW. However, production dips considerably in autumn (3.58 kWh/day) and reaches its lowest point in winter (2.63 kWh/day).
The substantial difference between summer and winter production highlights the importance of proper system sizing to ensure adequate year-round energy supply. While summer offers abundant solar resources, the reduced winter output may necessitate supplementary energy sources or energy storage solutions for consistent power availability.
Optimal Panel Placement
To maximize year-round solar energy production in Aigio, West Greece, fixed solar panels should be tilted at a 32-degree angle facing south. This optimal angle takes into account the city's latitude and seasonal sun positions, ensuring the best overall performance across all seasons.
Environmental Considerations
Aigio's Mediterranean climate generally favors solar energy production, with ample sunny days throughout the year. However, there are a few environmental factors to consider:
- Dust and pollen: The region's dry summers can lead to dust accumulation on panels, while spring may bring pollen. Regular cleaning can mitigate these issues.
- Coastal proximity: Aigio's location near the Gulf of Corinth may expose panels to salt spray, potentially accelerating corrosion. Using corrosion-resistant materials and protective coatings can help prevent damage.
Despite these minor challenges, Aigio remains an excellent location for solar PV installations. With proper planning and maintenance, solar energy systems in this Greek city can provide substantial clean energy throughout the year, particularly excelling in the spring and summer months.
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Aigio
Seasonal solar PV output for Latitude: 38.2516, Longitude: 22.0825 (Aigio, 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 Aigio, Greece
To maximize your solar PV system's energy output in Aigio, Greece (Lat/Long 38.2516, 22.0825) 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 Aigio, 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 Aigio, 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 Aigio, 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 Aigio, 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 Aigio, Greece
The topography around Aigio, Greece is quite diverse and interesting. Aigio is located on the northern coast of the Peloponnese peninsula, facing the Gulf of Corinth. The city itself sits on a narrow coastal plain, with the land rising quickly as you move inland.
Immediately south of Aigio, the terrain becomes hilly and then mountainous. These hills are part of the Panachaiko mountain range, which forms a dramatic backdrop to the city. The slopes are often steep and covered with a mix of Mediterranean vegetation, including olive groves and pine forests. As you go further south, the mountains become more rugged and reach higher elevations.
To the east and west of Aigio, the coastal plain extends for some distance, creating areas of flatter land. This plain is punctuated by numerous streams and small rivers that flow down from the mountains to the Gulf of Corinth, creating small valleys and gorges along their paths.
When considering areas nearby that would be most suited to large-scale solar PV (photovoltaic) installations, there are a few factors to consider. Ideally, solar farms need relatively flat or gently sloping land with good exposure to sunlight throughout the day. Given the topography around Aigio, the most suitable areas would likely be:
- Sections of the coastal plain to the east and west of Aigio, where there is flatter land available. These areas would need to be carefully selected to avoid prime agricultural land or environmentally sensitive areas.
- The lower slopes of the hills south of Aigio, where the terrain is not too steep. These areas might offer good sun exposure and less competition for land use compared to the coastal plain.
- Plateaus or wider valleys in the nearby mountains, if accessible. While these might be further from the city, they could offer large, relatively flat areas with good sun exposure.
It's important to note that any large-scale solar installation would need to be carefully planned to minimize environmental impact and consider factors such as grid connection, local regulations, and community acceptance. The rugged nature of much of the surrounding terrain does limit the options for very large installations, but there are likely several smaller areas that could be suitable for solar PV development.
