Solar PV Analysis of Sfantu Gheorghe, Romania
The location in Sfantu Gheorghe, Covasna County, Romania is moderately suitable for year-round energy generation through solar photovoltaic (PV) systems. The amount of energy you can get from a solar panel depends on how much sunlight it gets. In this case, the most productive season would be Summer, when each kilowatt of installed solar could produce around 6.36 kilowatt-hours per day. Spring and Autumn would bring moderate productivity with about 4.71 and 3.17 kilowatt-hours per day respectively, while Winter would be the least productive with only around 1.63 kilowatt-hours per day.
To maximize the total yearly production from a fixed panel installation at this location, it's best to tilt the panels at an angle of 39 degrees facing South.
However, there are factors that could hinder solar production in this area that need to be considered:
1) Weather: Romania experiences all four seasons which means less sunlight during Autumn and Winter months due to shorter days and cloudier skies.
2) Topography: If there are mountains or tall buildings nearby blocking sunlight from reaching the panels for part of the day.
3) Environmental Factors: Snowfall during winter could cover panels reducing their effectiveness.
To overcome these challenges:
- Regular cleaning and maintenance can help ensure snow or dust doesn't block sunlight from reaching your panels.
- Consider using tracking systems that move your panels to follow the sun throughout the day which can increase efficiency especially during lower light conditions in Winter.
- If possible install additional capacity so that even with reduced efficiency in less ideal seasons you still generate enough power overall.
Overall, while Sfantu Gheorghe isn't an ideal location for year-round maximum productivity due to its seasonal variations in sunlight availability; it is still quite viable especially if one takes into account adjustments like correct tilt angle and possibly using sun-tracking technology or installing extra capacity as needed based on your energy requirements.
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 Sfantu Gheorghe
Seasonal solar PV output for Latitude: 45.8647, Longitude: 25.7862 (Sfantu Gheorghe, 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 Sfantu Gheorghe, Romania
To maximize your solar PV system's energy output in Sfantu Gheorghe, Romania (Lat/Long 45.8647, 25.7862) 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 Sfantu Gheorghe, 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 Sfantu Gheorghe, 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 | 59° South in Winter | 38° 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 Sfantu Gheorghe, 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 Sfantu Gheorghe, 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 Sfantu Gheorghe, Romania
Sfantu Gheorghe is located in the central part of Romania, in the region of Transylvania. The city is surrounded by the Carpathian Mountains to the west and north and lies on a relatively flat plain near the confluence of three rivers: Olt, Mures, and Targu Secuiesc. The area is characterized by a mix of forests, grasslands, and agricultural fields.
Regarding large-scale solar PV installations, it would be ideal to locate them where there are vast open spaces with maximum sun exposure throughout the year. Agricultural fields or grasslands could potentially be suitable for such projects provided they don't interfere with farming activities or natural habitats.
However, it's crucial to consider factors like local climate (including cloud cover), land ownership rights, proximity to power grids for electricity transmission as well as potential environmental impacts before deciding on specific locations for solar farms.
Moreover, any large-scale solar project would also require thorough feasibility studies including detailed topographic surveys and solar irradiation assessments specific to proposed sites.
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.
