Solar PV Analysis of Bacau, Romania
Bacau, Romania, situated at latitude 46.5701 and longitude 26.9124, is a viable location for solar photovoltaic (PV) installations due to its seasonal variations in sunlight exposure and temperature. In the summer season, the extended daylight hours and elevated temperatures contribute to an average energy yield of 6.33 kWh per day for each kW of installed solar capacity.
As the year progresses into autumn, the daily solar energy production decreases to an average of 3.13 kWh per kW due to shorter daylight hours and cooler temperatures. The winter season sees a further decline in productivity with an average yield of just 1.49 kWh per day per kW owing primarily to reduced sunlight intensity and duration.
The spring season marks a rebound in solar power generation with an increase in output averaging at around 4.62 kWh/day per kW as daylight hours lengthen and temperatures rise once again.
For optimal performance of fixed-panel PV systems in Bacau, it is recommended that panels be installed at a tilt angle facing towards South by approximately 40 degrees from horizontal plane which aligns them more directly with incoming sunlight over the course of the year.
However, there are certain environmental factors that could potentially impact solar power production at this location; notably heavy cloud cover or high winds which can reduce incident sunlight on panels or cause physical damage respectively.
To mitigate these risks during installation phase:
- A site analysis should be conducted to choose a location less prone to shading from nearby structures or vegetation.
- Sturdy mounting systems resistant to wind loads should be used.
- Regular maintenance including panel cleaning can also help ensure maximum efficiency by preventing dust or debris accumulation which could further reduce light penetration onto panels' surface.
By taking these precautions during installation process along with appropriate system design considerations like optimum panel tilt angle, one can expect consistent performance from their PV system throughout different seasons despite potential local challenges while harnessing renewable energy effectively at this location in Bacau city located within Romania's borders.
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 Bacau
Seasonal solar PV output for Latitude: 46.5701, Longitude: 26.9124 (Bacau, 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 40° South in Bacau, Romania
To maximize your solar PV system's energy output in Bacau, Romania (Lat/Long 46.5701, 26.9124) throughout the year, you should tilt your panels at an angle of 40° 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 Bacau, 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 Bacau, Romania. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 40° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 31° 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 Bacau, 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 Bacau, 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 Bacau, Romania
The topography around Bacau, Romania is mostly flat with some rolling hills and valleys. Areas that would be most suitable for large-scale solar PV installations are those with the least amount of shade, such as open fields or rooftops in urban areas. The nearby city of Comanesti has several large open spaces that could potentially be used for this purpose. Additionally, some of the surrounding villages such as Poiana Tarcaului have wide open agricultural land which could also be utilized.
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.
