Solar PV Analysis of Vrilissia, Greece
Vrilissia, Attica, Greece, situated in the Northern Temperate Zone, is a decent location for generating solar energy throughout the year. However, it's not equally effective in all seasons. The amount of electricity produced by each kilowatt (kW) of installed solar power varies depending on the season.
During summer and spring, you can expect to generate more electricity - about 8.05 kilowatt-hours (kWh) per day in summer and 6.06 kWh/day in spring from each kW of installed solar power. This means these are the best times of year to generate solar energy at this location.
On the other hand, autumn and winter see a drop in production with only 3.62 kWh/day expected during autumn and an even lower 2.53 kWh/day during winter per kW of installed solar power.
For fixed panel installations at this location, tilting panels at an angle of 32 degrees towards South would be ideal to maximize total annual production from your solar photovoltaic (PV) system.
As for potential factors that could impede or reduce solar production: weather conditions such as cloudy days or heavy rainfall might affect output as they can limit sunlight exposure; dust or debris could accumulate on panels reducing their efficiency; local buildings or vegetation may also cast shadows onto panels which would decrease their productivity.
To mitigate these challenges: regular cleaning can help maintain panel efficiency by removing any accumulated dust or debris; trimming trees or considering nearby structures when installing your PV system can minimize shading issues; using advanced technology like tracking systems that follow sun's path across sky could also increase overall productivity despite less-than-ideal weather conditions.
In conclusion: while Vrilissia isn't perfect for year-round high-output PV generation due to its seasonal variations - it still offers good potential especially if preventative measures are taken into consideration during installation process.
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 Vrilissia
Seasonal solar PV output for Latitude: 38.033, Longitude: 23.8248 (Vrilissia, 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 Vrilissia, Greece
To maximize your solar PV system's energy output in Vrilissia, Greece (Lat/Long 38.033, 23.8248) 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 Vrilissia, 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 Vrilissia, 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 Vrilissia, 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 Vrilissia, 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 Vrilissia, Greece
Vrilissia, Greece is located in the Attica region of Greece, which is characterized by a mix of mountainous terrain and coastal plains. Vrilissia itself is situated on relatively flat land with some gentle hills.
The area has a Mediterranean climate with hot, dry summers and mild winters - conditions that are generally favorable for solar power generation. However, the specific suitability of locations for large-scale solar photovoltaic (PV) installations would depend on several factors such as land availability, sun exposure (solar irradiance), proximity to existing power infrastructure, environmental considerations and local regulations among others.
Flat open areas with high sun exposure would be most suitable for large-scale solar PV. The coastal plains could potentially provide such locations but detailed site assessments would be necessary to confirm their suitability. Areas near existing power infrastructure like substations or transmission lines would also be beneficial to reduce costs associated with connecting the solar farm to the grid.
In addition, rooftops in urban areas like Athens metropolitan area could also be used for smaller scale distributed solar PV installations. This can help offset electricity usage at the site and reduce demand on the grid especially during peak periods.
However, any actual project development should consider all these factors along with detailed technical studies and stakeholder consultations before proceeding.
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.
