Radom, Mazovia, Poland, situated at latitude 51.3984 and longitude 21.1585, presents a mixed picture for solar energy generation. This location in the Northern Temperate Zone experiences significant seasonal variations in solar potential, which impacts the effectiveness of photovoltaic (PV) systems throughout the year.

Seasonal Solar Performance

The solar energy output in Radom fluctuates considerably across seasons. Summer stands out as the most productive period, with an impressive 5.65 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second-best season, generating 4.15 kWh/day. However, autumn sees a substantial drop to 2.42 kWh/day, while winter performance plummets to a mere 0.97 kWh/day per kW installed.

These figures highlight that solar energy production in Radom is most effective from late spring through early autumn. During this period, longer daylight hours and higher sun angles contribute to enhanced solar panel efficiency.

Optimal Panel Installation

To maximize year-round solar energy production in Radom, Mazovia, fixed solar panels should be tilted at a 43-degree angle facing south. This optimal angle accounts for the location's latitude and seasonal sun path variations, ensuring the best possible energy capture throughout the year.

Environmental and Weather Considerations

Radom's climate presents some challenges for solar energy production. The region experiences cold winters with occasional snowfall, which can temporarily reduce panel efficiency. To mitigate this, panels can be installed at a steeper angle to promote snow sliding off. Additionally, the area may face overcast conditions, particularly in autumn and winter, further impacting solar output.

To address these factors, consider the following measures:

• Use high-efficiency panels designed for low-light conditions
• Implement a robust cleaning and maintenance schedule to remove snow and debris
• Consider a dual-axis tracking system for optimal sun exposure, if budget allows

While Radom's location is not ideal for year-round solar production, strategic installation and maintenance can still yield significant energy benefits, particularly during the more favorable months from spring to early autumn.

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

Solar output per kW of installed solar PV by season in Radom

Seasonal solar PV output for Latitude: 51.3984, Longitude: 21.1585 (Radom, Poland), 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 43° South in Radom, Poland

To maximize your solar PV system's energy output in Radom, Poland (Lat/Long 51.3984, 21.1585) throughout the year, you should tilt your panels at an angle of 43° 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 Radom, Poland

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 Radom, Poland. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 43° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
34° South in Summer	54° South in Autumn	65° South in Winter	43° 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 Radom, Poland

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 Radom, Poland.

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 Radom, Poland

The landscape surrounding Radom, Poland, is characterized by a gently rolling terrain typical of the Polish Lowlands. This region, known as the Radom Plain, features a mix of subtle hills, shallow valleys, and expansive flat areas. The topography is largely shaped by glacial processes that occurred during the last Ice Age, resulting in a diverse but generally mild landscape. To the north and east of Radom, the terrain is predominantly flat with occasional low hills. These areas are interspersed with small rivers and streams, creating a patchwork of agricultural fields and pockets of woodland. The southern and western parts of the region exhibit slightly more pronounced relief, with more frequent hills and deeper valleys.

Suitability for Large-Scale Solar PV

When considering areas near Radom for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be those that combine favorable topography with minimal environmental impact and proximity to existing infrastructure. The flat to gently sloping areas to the north and east of Radom present promising opportunities for solar PV development. These regions offer expansive open spaces with good sun exposure throughout the day. The lack of significant elevation changes reduces the risk of shading and simplifies the installation process. Areas of particular interest might include the agricultural lands between Radom and the towns of Kozienice to the northeast or Zwoleń to the east. These locations benefit from existing road networks for easy access and are generally free from major forests or protected natural areas that might pose obstacles to development. It's worth noting that while the rolling hills to the south and west of Radom might seem less ideal, modern solar technologies can adapt to mild slopes. Some of these areas could still be suitable, especially on south-facing slopes that receive optimal sunlight. However, any large-scale solar PV project would need to carefully consider local land use, environmental regulations, and grid connection possibilities. The final selection of sites would require detailed on-the-ground assessments and consultation with local authorities and communities.
