Roman, Neamț County, Romania, situated in the Northern Temperate Zone at coordinates 46.9178, 26.9182, experiences significant seasonal variations in solar energy production potential throughout the year. This location demonstrates the typical solar generation pattern of mid-latitude regions, with pronounced differences between summer and winter outputs.

Seasonal Solar Production

The solar electricity generation at this location follows a predictable seasonal pattern. During summer months, solar panels can produce an impressive 6.29kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 4.57kWh/day, while autumn yields a moderate 3.06kWh/day. Winter presents the greatest challenge with only 1.43kWh/day per installed kilowatt.

This substantial difference between summer and winter production (more than four times higher in summer) is characteristic of locations at this latitude, where the sun's path varies dramatically across seasons.

Optimal Installation Parameters

For fixed solar panel installations in Roman, Neamț County, the ideal tilt angle to maximize year-round energy production is 40 degrees facing South. This carefully calculated angle balances the seasonal variations in the sun's position to capture the maximum possible solar radiation throughout the entire year.

Environmental and Weather Considerations

Several environmental factors may impact solar production at this location:

• Snow accumulation during winter months can significantly reduce output if panels become covered, requiring either manual clearing or steep installation angles to promote self-clearing
• Occasional heavy clouds and precipitation in the region, particularly during late autumn and winter, further contribute to the seasonal production differences
• Dust and pollen accumulation during spring and summer can gradually reduce panel efficiency if not addressed

To mitigate these challenges, solar installations should incorporate regular maintenance schedules for panel cleaning, especially after winter and during pollen seasons. Snow guards or heating elements might be considered for winter operation, though these add complexity and cost to the system.

Overall, Roman's location provides good solar potential, particularly from late spring through early autumn. The substantial summer production can help offset the limited winter generation, making annual solar production reasonably effective despite the seasonal variations.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Seasonal solar PV output for Latitude: 46.9178, Longitude: 26.9182 (Roman, 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 Roman, Romania

To maximize your solar PV system's energy output in Roman, Romania (Lat/Long 46.9178, 26.9182) 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 Roman, 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 Roman, 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 Roman, 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 Roman, 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 Roman, Romania

Topography of Roman, Romania

Roman is situated in Neamț County in the northeastern part of Romania, within the historical region of Western Moldavia. The city lies in the Moldavian Plateau, specifically in the Moldova River valley where the Siret and Moldova rivers converge. This location places Roman in a relatively flat to gently undulating landscape characterized by broad river terraces and low hills. The immediate surroundings of Roman feature an average elevation of approximately 170-190 meters above sea level. The terrain gradually rises toward the west, where the Carpathian foothills begin, while to the east and southeast, the landscape maintains its generally flat to rolling character as it extends toward the Siret River floodplain. The Moldova River valley creates a natural corridor through this area, with alluvial soils and relatively level terrain. This river valley has historically served as an important transportation route and agricultural zone. The broader region surrounding Roman is characterized by a mix of agricultural lands, scattered forests, and small settlements.

Potential Areas for Solar PV Development

The topographical characteristics of the region surrounding Roman offer several promising areas for large-scale solar photovoltaic development. The most suitable locations would be found in the following areas: The eastern and southeastern plains extending from Roman toward the Siret River provide extensive flat terrain with minimal shading concerns. These areas currently support agriculture but could potentially accommodate dual-use solar installations that allow for continued farming activities beneath elevated panels. The gently sloping south-facing hillsides found particularly to the north and northeast of Roman present favorable conditions for solar capture. These modest inclines naturally optimize the angle of solar exposure while typically experiencing less agricultural pressure than the fertile river valleys. The broad river terraces along the Moldova and Siret rivers, particularly those elevated above flood levels, offer substantial level areas with good drainage and existing access to transportation infrastructure. These terraces typically feature well-draining soils that would provide stable foundations for solar array installations. Areas of degraded or marginal agricultural land scattered throughout the region would minimize conflicts with food production while providing the extensive space required for utility-scale solar development. Several such zones can be found in the transitional areas between the river valleys and higher elevations. The relatively open landscape with minimal tall vegetation or major topographical barriers throughout much of the Moldavian Plateau surrounding Roman ensures limited shadowing effects, maximizing potential solar capture throughout the day and across seasons. From a topographical perspective alone, the region offers considerable potential for solar energy development, with its combination of level terrain, gently south-facing slopes, and open landscapes creating favorable conditions for large-scale photovoltaic installations.
