Solar PV Analysis of Polygyros, Greece
Based on the given data, it appears that Polygyros, Central Macedonia, Greece has a fair potential for solar energy production year-round. However, the efficiency varies significantly depending on the season.
During summer months when there is more sunlight, each kilowatt of installed solar panels can generate around 7.56 kilowatt-hours per day. This drops to about half in autumn (3.50 kWh/day) and even lower in winter (2.50 kWh/day). The production increases again during spring with approximately 5.79 kWh/day.
This suggests that while solar energy can be generated throughout the year at this location, summer and spring are ideal times due to longer daylight hours and better sun exposure compared to autumn and winter months.
For maximum efficiency from these panels all-year-round at this location, they should ideally be tilted towards south at an angle of 34 degrees. This orientation helps capture maximum sunlight as it moves across the sky throughout different seasons.
As for environmental or weather factors that could impede solar production at this location - Greece generally enjoys ample sunshine throughout most of the year but possible challenges could include dust or dirt accumulation on panels which reduces their efficiency; occasional rainstorms or high winds might also pose a risk to panel integrity.
To counter these issues:
1) Regular cleaning of solar panels is recommended to remove any dust or dirt.
2) Sturdy installation methods should be used to protect against wind damage.
3) Additionally, using high-quality durable materials for building frames can help withstand weather conditions.
4) In case of frequent cloudy days or unexpected bad weather events which may affect power generation from sun rays directly hitting your panels - you might want consider battery storage systems so excess power generated during sunny periods can be stored and used when needed later on.
Overall though based on provided info - Polygyros seems like a pretty good place for harnessing solar energy!
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 Polygyros
Seasonal solar PV output for Latitude: 40.3711, Longitude: 23.4353 (Polygyros, 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 34° South in Polygyros, Greece
To maximize your solar PV system's energy output in Polygyros, Greece (Lat/Long 40.3711, 23.4353) throughout the year, you should tilt your panels at an angle of 34° 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 Polygyros, 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 Polygyros, Greece. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 34° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 24° South in Summer | 44° South in Autumn | 55° 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 Polygyros, 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 Polygyros, 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 Polygyros, Greece
Polygyros is located in the region of Central Macedonia, Greece. The topography around Polygyros is a mix of hilly and mountainous terrain with some flatland areas. It is surrounded by rich vegetation and forests, mainly consisting of pine trees. The area also has several small rivers flowing through it.
The most suitable areas for large-scale solar PV installations near Polygyros would be the open flatlands that receive a good amount of sunlight throughout the year. Specifically, agricultural lands or non-forested areas that are not used for cultivation could be potential sites for solar farms.
However, it's important to note that suitability for solar PV also depends on factors such as local climate conditions (amount of sunlight received), land use restrictions, proximity to power grids, and accessibility for installation and maintenance work. Therefore, a detailed site-specific assessment would be required to determine the most suitable locations.
As per EU regulations on renewable energy projects in Natura 2000 sites (which may apply given Greece's membership in the EU), any project development should ensure minimal impact on local biodiversity and ecosystems.
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.
