Solar PV Analysis of Techirghiol, Romania
Techirghiol, Constanța County, Romania, situated at 44.0523° N latitude and 28.6043° E longitude, presents a varied landscape for solar energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal fluctuations in solar energy production, which impacts the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Energy Production
The solar energy output at Techirghiol varies considerably across the four meteorological seasons. Summer stands out as the most productive period, with an impressive 6.98 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season, generating 5.17 kWh/day. Autumn sees a significant drop to 3.24 kWh/day, while winter experiences the lowest output at 1.64 kWh/day.
These figures highlight that the location is most ideal for solar energy production during the warmer months, particularly from late spring through early autumn. During this period, longer daylight hours and higher sun angles contribute to increased energy generation.
Optimal Panel Tilt
For fixed solar panel installations in Techirghiol, Constanța County, the ideal tilt angle to maximize year-round production is 37 degrees facing south. This angle is calculated based on the location's latitude and accounts for the Earth's elliptical orbit, ensuring optimal exposure to sunlight throughout the year.
Environmental and Weather Factors
While Techirghiol's location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact solar panel efficiency:
- Snow accumulation in winter, which can cover panels and reduce output
- Dust and salt spray from the nearby Black Sea, which may accumulate on panel surfaces
To mitigate these issues, preventative measures can be taken during installation. These include using a slightly steeper tilt angle to encourage snow sliding off panels, implementing a regular cleaning schedule, and considering protective coatings to minimize salt and dust accumulation. Additionally, investing in high-quality, weather-resistant panels can help ensure consistent performance in varying conditions.
In conclusion, while Techirghiol experiences significant seasonal variations in solar energy production, it remains a viable location for solar PV installations. With proper planning and maintenance, solar energy systems can effectively harness the abundant summer and spring sunlight, while still providing useful energy output during the less productive autumn and winter months.

Solar output per kW of installed solar PV by season in Techirghiol
Seasonal solar PV output for Latitude: 44.0523, Longitude: 28.6043 (Techirghiol, Romania), 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 37° South in Techirghiol, Romania
To maximize your solar PV system's energy output in Techirghiol, Romania (Lat/Long 44.0523, 28.6043) throughout the year, you should tilt your panels at an angle of 37° 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 Techirghiol, Romania
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 Techirghiol, Romania. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 37° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 28° South in Summer | 47° South in Autumn | 58° South in Winter | 36° 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 Techirghiol, Romania

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 Techirghiol, Romania
The area around Techirghiol, Romania, is characterized by relatively flat terrain with some gentle undulations. This region is part of the Dobrogea plateau, which is known for its low-lying landscape. The town of Techirghiol itself is situated near the western shore of Lake Techirghiol, a saltwater lake that is a prominent feature of the local topography.
To the east of Techirghiol, you'll find the Black Sea coast, which is marked by sandy beaches and low cliffs. The coastline in this area is generally straight, with few significant indentations or promontories. Moving inland to the west, the terrain gradually rises, but the elevation change is modest, typically not exceeding 50-100 meters above sea level.
The surrounding countryside is predominantly rural, with open fields and scattered patches of vegetation. There are few forests or dense wooded areas in the immediate vicinity. The landscape is often described as steppe-like, with grassy plains that stretch for considerable distances.
Suitable Areas for Large-Scale Solar PV
For large-scale solar photovoltaic (PV) installations, the areas to the west and northwest of Techirghiol would be most suitable. These regions offer several advantages for solar energy development:
1. Flat terrain: The gently rolling plains provide ample space for large arrays of solar panels without the need for extensive land modification.
2. Open landscape: The lack of dense forests or tall structures means there are fewer obstacles to cast shadows on solar panels, maximizing sun exposure throughout the day.
3. Agricultural land: Much of the area is currently used for agriculture, which could potentially be converted to solar farms with minimal environmental impact.
4. Distance from the coast: By moving slightly inland, installations can avoid the corrosive effects of salt spray from the Black Sea, which could potentially damage solar equipment over time.
5. Accessibility: The region has a reasonably developed road network, making it easier to transport equipment and maintain solar installations.
It's worth noting that while the area around Techirghiol has good potential for solar energy, any large-scale project would require detailed site-specific assessments, including environmental impact studies and grid connection evaluations. Additionally, care should be taken to balance energy development with the preservation of agricultural land and local ecosystems.
