Graph of hourly avg kWh electricity output per kW of Solar PV installed in Deva, Romania (by season)

Deva, Hunedoara County, Romania's location is decent for generating energy through solar panels, but it's not the best. This place gets different amounts of sunlight throughout the year. In summer, each kilowatt of installed solar can generate 6.67 kilowatt-hours per day. However, in autumn and winter, this amount decreases significantly to 3.16 and 1.55 kilowatt-hours per day respectively due to less sunlight during these seasons. It improves in spring with an average of 4.80 kilowatt-hours per day.

The best time for generating solar energy at this location is during the summer because that's when it gets the most sunlight throughout the year.

For a fixed panel installation here, tilting panels at an angle of 39 degrees towards the south would be ideal as it would maximize total yearly production from solar PV.

As far as environmental factors are concerned which could impede solar production at this location - while there aren't any significant ones mentioned - general considerations should include local weather patterns (cloud cover or snowfall), topography (mountains or tall buildings casting shadows), and potential sources of dust or debris that could cover panels and reduce efficiency.

To ensure greater energy production despite these potential challenges:
- Regular cleaning/maintenance can help keep panels clear from dust/debris.
- If possible, place panels where they will be least likely to get shaded by nearby trees/buildings.
- Consider investing in more efficient panel technology that performs better under less-than-ideal light conditions.

In conclusion, while Deva isn't optimal for harnessing solar power all year round due to its seasonal variations in sunlight availability; with proper installation techniques and maintenance practices one can still generate a reasonable amount of electricity using solar PV systems here especially during summertime when sunlight availability is highest.

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.

Seasonal solar PV output for Latitude: 45.8874, Longitude: 22.8968 (Deva, 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:

Summer
Average 6.67kWh/day in Summer.
Autumn
Average 3.16kWh/day in Autumn.
Winter
Average 1.55kWh/day in Winter.
Spring
Average 4.80kWh/day in Spring.

 

Ideally tilt fixed solar panels 39° South in Deva, Romania

To maximize your solar PV system's energy output in Deva, Romania (Lat/Long 45.8874, 22.8968) 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.

At Latitude: 45.8874, Longitude: 22.8968, the ideal angle to tilt panels is 39° South

Seasonally adjusted solar panel tilt angles for Deva, 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 Deva, 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
29° South in Summer 49° South in Autumn 59° South in Winter 38° South in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Deva, Romania as follows: In Summer, set the angle of your panels to 29° facing South. In Autumn, tilt panels to 49° facing South for maximum generation. During Winter, adjust your solar panels to a 59° angle towards the South for optimal energy production. Lastly, in Spring, position your panels at a 38° angle facing South to capture the most solar energy in Deva, Romania.

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 Deva, 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 Deva, 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 Deva, Romania

Deva, Romania is located in the western part of the country, in the region known as Transylvania. The topography around Deva is characterized by a mixture of hills and plains. The city itself sits at an elevation of approximately 187 meters above sea level.

To the west and north-west of Deva lie the Apuseni Mountains, part of the Carpathian mountain range. These mountains are characterized by their rugged terrain and dense forests. To the south-east lies more flatland which gradually rises into hills as you move further away from town.

In terms of suitability for large-scale solar PV installations, flat or gently sloping areas are typically preferred due to ease of installation and maintenance. Therefore, it would be more suitable to install a large-scale solar PV system in areas southeast or northeast from Deva where there are plains or gently sloping hills.

However, other factors also need to be considered such as sunlight exposure (solar irradiance), land ownership and use (agricultural land vs unused land), proximity to grid connection points for electricity transmission and local regulations regarding renewable energy projects.

Additionally, while mountains may not be ideal for large scale ground-mounted solar farms due to their steep slopes and potential shading issues, they can still be used for smaller scale installations like rooftop solar panels on homes or businesses located there.

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.
