Solar Energy Potential in Karditsa, Greece
Karditsa, Greece, located at latitude 39.3648 and longitude 21.9282, 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. The summer months provide the most favorable conditions for solar energy generation in Karditsa. With an impressive 7.70 kWh per day output for each kilowatt of installed solar capacity, summer is the peak season for solar production. Spring follows closely behind, yielding 6.00 kWh per day, making it the second-best season for solar energy harvesting. Autumn and winter present more challenging conditions for solar energy production. Autumn sees a significant drop to 3.52 kWh per day, while winter experiences the lowest output at 2.46 kWh per day. These seasonal variations highlight the importance of proper system sizing to ensure adequate energy supply throughout the year.Optimizing Solar Panel Installation
To maximize year-round solar energy production in Karditsa, fixed solar panels should be installed at a tilt angle of 33 degrees facing south. This optimal angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data.Environmental and Weather Considerations
While Karditsa generally offers favorable conditions for solar energy production, there are some environmental factors to consider: 1. Dust and pollen: The agricultural nature of the Thessaly region, where Karditsa is located, may lead to increased dust and pollen in the air, potentially affecting panel efficiency. 2. Occasional snowfall: Though rare, winter snowfall can temporarily reduce solar panel output. To mitigate these factors, consider implementing the following preventative measures:- Regular cleaning schedule for solar panels to remove dust and pollen buildup
- Installation of panels at a steeper angle to facilitate snow sliding off
- Use of anti-reflective coatings on panels to improve performance in low-light conditions
Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Ideally tilt fixed solar panels 33° South in Karditsa, Greece
To maximize your solar PV system's energy output in Karditsa, Greece (Lat/Long 39.3648, 21.9282) throughout the year, you should tilt your panels at an angle of 33° 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 Karditsa, 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 Karditsa, Greece. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 23° South in Summer | 43° South in Autumn | 54° South in Winter | 31° 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 Karditsa, 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 Karditsa, 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 Karditsa, Greece
The area around Karditsa, Greece, is characterized by diverse topography that includes both flat plains and hilly terrain. Karditsa itself is situated in the western part of the Thessalian Plain, one of the largest and most fertile lowland areas in Greece. This plain stretches out to the east and northeast of the city, offering vast expanses of relatively flat land.
To the west and southwest of Karditsa, the landscape gradually transitions into the foothills of the Pindus Mountains. These hills become progressively steeper and more rugged as you move further west. The Pindus range forms a natural barrier between Thessaly and the regions of Epirus and Western Macedonia.
The southern part of the Karditsa regional unit is dominated by the artificial Lake Plastiras, created by damming the Tavropos River. This picturesque lake is surrounded by forested hills and mountains, creating a stark contrast to the flat plains to the north.
For large-scale solar PV installations, the most suitable areas would likely be found in the Thessalian Plain to the east and northeast of Karditsa. This region offers several advantages for solar energy development:
- Flat terrain: The level ground of the plain makes construction and maintenance of solar arrays easier and more cost-effective.
- Open spaces: The agricultural nature of the plain means there are large, unobstructed areas available for solar farms.
- Good solar exposure: The region experiences plenty of sunshine throughout the year, making it ideal for solar energy generation.
- Proximity to infrastructure: The plain's developed nature means it's likely easier to connect to the existing power grid and transportation networks.
While the hilly and mountainous areas to the west might offer some suitable locations for smaller solar installations, their rugged terrain and potential shading from nearby peaks make them less ideal for large-scale projects. Additionally, these areas often have greater ecological sensitivity and may face more regulatory hurdles for development.
It's important to note that any large-scale solar PV project would need to carefully consider local land use, agricultural practices, and environmental regulations. The fertile nature of the Thessalian Plain means that there may be competing interests between solar energy development and agriculture, which would need to be balanced through careful planning and community engagement.
