The location in Chiajna, Ilfov, Romania, situated at 44.4626° N latitude and 25.969° E longitude, presents varying potential for solar energy generation throughout the year. This Northern Temperate Zone location experiences significant seasonal fluctuations in solar output, which affect the overall efficiency of photovoltaic (PV) systems.
Seasonal Solar Output
Solar energy production in Chiajna peaks during the summer months, with an average daily output of 6.83 kWh per kW of installed solar capacity. Spring follows as the second most productive season, generating 5.08 kWh/day. Autumn sees a considerable decrease in output to 3.24 kWh/day, while winter experiences the lowest production at 1.77 kWh/day.
These figures indicate that solar energy generation is most effective from late spring through early autumn. During this period, longer daylight hours and higher sun angles contribute to increased solar panel efficiency.
Optimal Panel Tilt
For fixed solar panel installations in Chiajna, Ilfov, the ideal tilt angle to maximize year-round energy production is 38 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, balancing the varying sun positions across seasons.
Environmental Considerations
While Chiajna's location is generally favorable for solar energy production, there are some environmental factors to consider:
- Snow accumulation in winter can temporarily reduce panel efficiency
- Occasional air pollution from nearby Bucharest may slightly decrease solar irradiance
To mitigate these issues, installing panels at the recommended 38-degree angle helps shed snow more easily. Regular cleaning and maintenance can also address any buildup of pollutants on the panels, ensuring optimal performance.
In conclusion, while Chiajna experiences significant seasonal variations in solar output, proper panel positioning and maintenance can help maximize energy production throughout the year. The location is particularly well-suited for solar energy generation during the spring and summer months, with careful planning required to offset reduced winter output.

Solar output per kW of installed solar PV by season in Chiajna
Seasonal solar PV output for Latitude: 44.4626, Longitude: 25.969 (Chiajna, 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 38° South in Chiajna, Romania
To maximize your solar PV system's energy output in Chiajna, Romania (Lat/Long 44.4626, 25.969) throughout the year, you should tilt your panels at an angle of 38° 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 Chiajna, 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 Chiajna, Romania. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 38° 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 | 48° South in Autumn | 58° South in Winter | 37° 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 Chiajna, 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 Chiajna, 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 Chiajna, Romania
The topography around Chiajna, Romania, is characterized by a relatively flat landscape typical of the Romanian Plain. This area, located just northwest of Bucharest, is part of the larger Wallachian Plain, which stretches across southern Romania. The terrain in and around Chiajna is predominantly low-lying, with minimal elevation changes and few notable geographic features. The region surrounding Chiajna is primarily composed of gently rolling plains and agricultural fields. The land is mostly flat, with slight undulations that are barely noticeable to the casual observer. This area has been shaped by the Dâmbovița River, which flows nearby, contributing to the fertile soil that has made this region suitable for farming.
Suitability for Large-Scale Solar PV
When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain around Chiajna offers numerous advantages for solar energy development. The lack of significant geographical obstacles means that large, unobstructed areas are available for the placement of solar panels. The agricultural lands surrounding Chiajna could potentially be repurposed for solar farms. These open spaces receive ample sunlight throughout the year, making them ideal candidates for solar PV installations. The flat landscape also simplifies construction and maintenance processes, reducing overall costs associated with large-scale solar projects. Areas to the south and southeast of Chiajna, extending towards the outskirts of Bucharest, might be particularly well-suited for solar PV development. These locations benefit from the region's favorable climate, characterized by long, sunny summers and relatively mild winters. Additionally, the proximity to Bucharest's power infrastructure could facilitate easier grid integration for any new solar energy projects. It's important to note that while the topography is favorable, other factors such as local regulations, land ownership, and environmental considerations would need to be carefully evaluated before implementing any large-scale solar PV projects in the area. Proper planning and consultation with local authorities and communities would be essential to ensure the successful development of solar energy resources in this region.Romania solar PV Stats as a country
Romania ranks 39th in the world for cumulative solar PV capacity, with 1,398 total MW's of solar PV installed. This means that 3.40% of Romania's total energy as a country comes from solar PV (that's 24th in the world). Each year Romania is generating 74 Watts from solar PV per capita (Romania ranks 43rd in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Romania?
Yes, there are incentives for businesses wanting to install solar energy in Romania. The Romanian government offers a number of financial incentives and subsidies for businesses that invest in renewable energy sources such as solar power. These include grants, tax deductions, and other forms of support. Additionally, the government has set up a Renewable Energy Support Scheme (RES) which provides additional funding for projects related to renewable energy sources such as solar power.
