Solar PV Analysis of Oltenita, Romania
Situated in the Northern Temperate Zone, Oltenita, Calarasi, Romania demonstrates a solid potential for solar power generation. The average daily energy output per kilowatt of installed solar capacity varies across seasons: 6.70 kWh in summer, 3.25 kWh in autumn, 1.70 kWh in winter and 5.12 kWh in spring.
The highest yield is observed during the summer months due to prolonged daylight hours and increased sunlight intensity. However, even during less favourable seasons such as autumn and winter, there is still a reasonable amount of energy production from solar installations.
Given its geographical position at latitude 44.0846 and longitude 26.6227, the optimal tilt angle for fixed panel installations is towards south at an angle of approximately 37 degrees to maximize annual energy capture from the sun.
However, local climatic conditions could potentially affect solar production efficiency at this location occasionally throughout the year; these include periods of heavy rain or snowfall that can obstruct sunlight reaching the panels directly or create a layer on their surface reducing their effectiveness.
To mitigate these environmental influences on power generation efficiency it's advisable to consider installing a system for regular cleaning or removal of any obstructions from panel surfaces; this will help ensure they remain clear and capable of capturing maximum sunlight available throughout each day irrespective of seasonality differences or weather variations encountered over time within this region's climate pattern.
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 114 locations across Romania. 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 Oltenita
Seasonal solar PV output for Latitude: 44.0846, Longitude: 26.6227 (Oltenita, 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 Oltenita, Romania
To maximize your solar PV system's energy output in Oltenita, Romania (Lat/Long 44.0846, 26.6227) 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 Oltenita, 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 Oltenita, 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 | 48° 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 Oltenita, 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 Oltenita, 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 Oltenita, Romania
The topography around Oltenita, Romania is generally flat with some rolling hills. The area to the south and east of the city is mostly flat, making it ideal for large-scale solar PV installations. Areas to the north and west are slightly more hilly, but could still be suitable for solar development as long as there are no major obstacles such as trees or buildings blocking the sun's rays.
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.
