Solar PV Analysis of Igoumenitsa, Greece
The location at Igoumenitsa, Epirus, Greece is decent for generating energy through solar power, but it's not the best. During the summer and spring, you can expect a pretty good amount of energy production - 8.04 kilowatt-hours per day in summer and 6.24 kilowatt-hours per day in spring for each kilowatt of solar panel installed. However, during autumn and winter, the energy production drops significantly to 3.84 and 2.55 kilowatt-hours per day respectively.
Given these figures, if you want to generate solar power in this location, it would be ideal to do so during summer and spring when sunlight is abundant.
To get the most out of your solar panels throughout the year at this location, they should be tilted at an angle of 33 degrees facing south. This position will allow them to capture as much sunlight as possible.
As far as environmental or local factors that could hinder solar production here are concerned; since Igoumenitsa is a coastal city with mountains nearby there may be some issues with cloud cover or shadows from mountains which could reduce sunlight exposure on panels especially during winter months when days are shorter anyway; also dust or salt spray from sea air might cause build-up on panels reducing their efficiency over time.
To overcome these potential problems:
1) Regular cleaning of the panels can help maintain their efficiency by removing any dust or salt deposits.
2) If possible install your system where it will have clear unobstructed access to sunlight most hours of daylight i.e., away from shadows caused by buildings or natural features like mountains.
3) Also consider using tracking systems that automatically adjust angle of your panels throughout day/year ensuring they always face directly towards sun maximizing their output potential regardless season/time-of-day.
4) Lastly using high-quality durable panels designed for harsher conditions may also be beneficial given local climate factors.
So while this location isn't the most ideal for solar power, with careful planning and maintenance you can still generate a decent amount of energy from it.
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 Igoumenitsa
Seasonal solar PV output for Latitude: 39.5032, Longitude: 20.2604 (Igoumenitsa, 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 33° South in Igoumenitsa, Greece
To maximize your solar PV system's energy output in Igoumenitsa, Greece (Lat/Long 39.5032, 20.2604) 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 Igoumenitsa, 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 Igoumenitsa, 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 | 32° 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 Igoumenitsa, 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 Igoumenitsa, 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 Igoumenitsa, Greece
Igoumenitsa, Greece is located in the northwestern part of the country and has a diverse topography. It is surrounded by mountains to the north and east, while to its south and west lies the Ionian Sea. The area also includes plains, hills, valleys and forests.
Considering solar PV installations, flat terrains are generally preferred for large-scale projects due to ease of installation and maintenance. Therefore, any existing flat lands or cleared areas would be suitable for such projects.
However, it's important to note that hilly or mountainous areas can still be viable for solar PV installations if they have good sun exposure (south-facing slopes in Northern hemisphere). The specific suitability would depend on factors like slope steepness, soil stability etc.
Moreover, rooftop solar installations could be a viable option within the city itself considering its coastal location which likely receives significant amount of sunlight.
For an accurate assessment though one must conduct a detailed site survey considering all relevant factors including local climate conditions (like average sunshine hours), legal regulations among others.
Remember that proximity to power grid infrastructure is also critical as it impacts cost and feasibility of power transmission from solar farms.
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.
