The location in Turda, Cluj County, Romania, situated at latitude 46.5659 and longitude 23.7887, presents varying potential for solar energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal fluctuations in solar output, which impacts the overall efficiency of photovoltaic (PV) systems.

Seasonal Solar Performance

Summer stands out as the most productive season for solar energy generation in Turda, Cluj County, with an impressive daily output of 6.52 kWh per kW of installed solar capacity. Spring follows as the second-best season, yielding 4.73 kWh per day. Autumn sees a considerable drop in production, with 3.08 kWh per day, while winter experiences the lowest output at just 1.35 kWh per day.

These figures highlight the substantial variation in solar potential across seasons, with summer producing nearly five times more energy than winter. This disparity underscores the importance of efficient energy storage and grid integration to balance the fluctuating supply throughout the year.

Optimal Panel Positioning

To maximize year-round solar energy production in Turda, Cluj County, fixed solar panels should be tilted at an angle of 39 degrees facing south. This optimal angle has been calculated considering the location's latitude, seasonal sun paths, and daily solar elevation angles, ensuring the best possible exposure to sunlight throughout the year.

Environmental and Weather Considerations

While Turda's location is generally favorable for solar energy production, there are some environmental and weather factors that could potentially impact system performance:

• Snow accumulation in winter may temporarily reduce panel efficiency
• Occasional dust storms or air pollution could decrease solar irradiance

To mitigate these issues, installers should consider using self-cleaning panels or implementing regular maintenance schedules. Additionally, slightly increasing the tilt angle of panels during winter can help shed snow more effectively, while robust mounting systems can protect against potential wind damage.

In conclusion, while Turda experiences significant seasonal variations in solar output, proper system design and maintenance can help maximize energy production throughout the year. The location's solar potential is particularly strong during summer and spring, making it a viable option for PV installations with appropriate energy management strategies.

Solar output per kW of installed solar PV by season in Turda

Seasonal solar PV output for Latitude: 46.5659, Longitude: 23.7887 (Turda, 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 39° South in Turda, Romania

To maximize your solar PV system's energy output in Turda, Romania (Lat/Long 46.5659, 23.7887) throughout the year, you should tilt your panels at an angle of 39° 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 Turda, 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 Turda, Romania. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 39° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
30° South in Summer	50° South in Autumn	60° South in Winter	39° 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 Turda, Romania

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 Turda, Romania.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Turda, Romania

The area surrounding Turda, Romania, located at 46.5659° North latitude and 23.7887° East longitude, features a diverse and picturesque topography. This region is characterized by a mix of rolling hills, valleys, and plateaus, creating a varied landscape that transitions from the Transylvanian Plateau to the Apuseni Mountains. To the west of Turda, the terrain gradually rises towards the Apuseni Mountains, with increasingly steep slopes and higher elevations. These mountains, part of the Western Carpathians, provide a dramatic backdrop to the area and contribute to its scenic beauty. The foothills of the Apuseni Mountains offer a combination of forested areas and open grasslands. East of Turda, the landscape becomes more gentle, with undulating hills and wide valleys typical of the Transylvanian Plateau. This area is known for its agricultural potential, with many fields and pastures dotting the countryside. The Arieș River, which flows through Turda, has carved a valley that runs roughly east to west, creating a natural corridor through the region.

Solar PV Potential

When considering areas near Turda for large-scale solar PV installations, several factors come into play. The most suitable locations would generally be found in the more open, flatter areas to the east and southeast of Turda. These regions, part of the Transylvanian Plateau, offer several advantages for solar energy development: Firstly, the gently rolling terrain provides ample space for large solar arrays without the need for extensive land modification. The open nature of the landscape also means fewer obstacles that could cast shadows on solar panels, maximizing their exposure to sunlight throughout the day. Secondly, these areas typically have lower agricultural value compared to the fertile river valleys, making them more available for alternative land uses such as solar farms. This reduces potential conflicts with food production and helps preserve more productive agricultural land. Lastly, the proximity to existing infrastructure, including roads and power transmission lines, makes these areas more economically viable for large-scale solar projects. The relatively flat terrain also simplifies construction and maintenance processes. While the hilly and mountainous regions to the west of Turda may receive good solar radiation due to their elevation, the challenging terrain and potential environmental concerns make them less suitable for large-scale solar installations. However, these areas might be appropriate for smaller, distributed solar projects that can take advantage of south-facing slopes. In conclusion, the varied topography around Turda offers different opportunities for solar energy development, with the flatter, open areas to the east and southeast presenting the most promising locations for large-scale solar PV installations.
