The location at Larissa, Thessaly, Greece seems to be a pretty good spot for generating energy via solar panels year-round. However, the effectiveness varies depending on the season. During summer and spring, you can expect more electricity output (7.72kWh/day in Summer, 6.01kWh/day in Spring) compared to autumn and winter (3.46kWh/day in Autumn, 2.60kWh/day in Winter). Therefore, installing solar panels would be most beneficial during warmer months of the year.
To get the most out of your solar panels all-year-round at this location though, it's recommended that they are tilted at an angle of 33 degrees facing South - this will help maximize their exposure to sunlight throughout different times of the year.
As for local factors that could affect solar production: like anywhere else in the world weather conditions such as cloud cover or heavy rainfall could potentially reduce how much sunlight reaches your solar panels and therefore lower their productivity levels slightly from time to time.
However these kinds of environmental factors aren't usually significant enough over a longer period to stop someone from choosing to install solar power if they wish too; unless perhaps if there was unusually high amounts of cloud cover or rain expected consistently throughout certain periods which is not typically characteristic for Larissa's climate.
When installing your solar panels though preventative measures should still be taken into account just incase - such as ensuring there is proper drainage around your installation site so water doesn't build up around them when it rains heavily which could otherwise cause damage or reduce performance levels; also keeping them clean from dust or other debris regularly can also help ensure maximum light absorption efficiency too.
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 Larissa
Seasonal solar PV output for Latitude: 39.644, Longitude: 22.4217 (Larissa, 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 Larissa, Greece
To maximize your solar PV system's energy output in Larissa, Greece (Lat/Long 39.644, 22.4217) 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 Larissa, 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 Larissa, 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 Larissa, 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 Larissa, 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 Larissa, Greece
Larissa, Greece is located in the Thessaly region and is characterized by a flat landscape surrounded by mountains. The city itself lies in a fertile plain at the foot of Mount Ossa to the northeast and Mount Olympus to the north. This plain, known as the Thessalian Plain or Larissa Plain, is one of Greece's most productive agricultural regions.
For large-scale solar photovoltaic (PV) installations, flat terrains are typically more suitable due to easier installation and maintenance. Therefore, areas within the Thessalian Plain surrounding Larissa could be well-suited for such projects. It's also important to consider sunlight exposure: Larissa has a Mediterranean climate with plenty of sunshine throughout the year which makes it ideal for solar power generation.
However, actual site selection would require detailed studies considering various factors including land availability and use restrictions (e.g., preserving agricultural land), proximity to electrical grid connections or demand centers, environmental impacts among others.
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.
