Altenmarkt im Pongau, Austria, located at 47.3848°N, 13.4188°E, presents a challenging environment for year-round solar PV energy generation. This Northern Temperate Zone location experiences significant seasonal variations in solar output, which greatly impacts the efficiency of solar installations.

Seasonal Solar Performance

The solar energy production at this location varies dramatically throughout the year. Summer months yield the highest output at 5.74 kWh per day for each kW of installed solar capacity. Spring follows with 4.28 kWh/day, while autumn sees a decrease to 3.01 kWh/day. Winter performance drops significantly to just 1.68 kWh/day, highlighting the challenges faced during the colder months.

Optimal Panel Positioning

To maximize year-round solar energy production, fixed panels should be tilted at a 41-degree angle facing south. This orientation helps to capture the most sunlight possible across all seasons, balancing the lower winter sun angle with the higher summer sun position.

Peak Generation Periods

The ideal times for solar energy generation in Altenmarkt im Pongau are during the late spring, summer, and early autumn months. These periods offer longer daylight hours and more direct sunlight, resulting in significantly higher energy yields compared to the winter season.

Environmental and Weather Factors

Several factors can impede solar production at this location:

• Heavy snowfall in winter can cover panels, reducing efficiency
• Frequent cloud cover, especially in autumn and winter, can limit solar exposure

To mitigate these issues, consider installing panels at a steeper angle to encourage snow sliding off. Additionally, using high-efficiency panels and incorporating snow removal systems can help maintain production during winter months. Regular maintenance and cleaning are crucial to ensure optimal performance year-round.

While Altenmarkt im Pongau faces challenges for solar energy production, particularly in winter, proper planning and installation techniques can still make solar PV a viable energy option for this Alpine location.

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 Altenmarkt Im Pongau

Seasonal solar PV output for Latitude: 47.3848, Longitude: 13.4188 (Altenmarkt Im Pongau, Austria), 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 41° South in Altenmarkt Im Pongau, Austria

To maximize your solar PV system's energy output in Altenmarkt Im Pongau, Austria (Lat/Long 47.3848, 13.4188) throughout the year, you should tilt your panels at an angle of 41° 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 Altenmarkt Im Pongau, Austria

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 Altenmarkt Im Pongau, Austria. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 41° 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	61° South in Winter	40° 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 Altenmarkt Im Pongau, Austria

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 Altenmarkt Im Pongau, Austria.

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 Altenmarkt Im Pongau, Austria

Altenmarkt im Pongau, located in the Austrian state of Salzburg, is nestled within the picturesque Salzburg Alps. The topography of this region is characterized by dramatic mountain landscapes, deep valleys, and winding rivers. The town itself sits at an elevation of approximately 840 meters above sea level, surrounded by peaks that rise well over 2,000 meters. The immediate area around Altenmarkt im Pongau features a mix of gentle slopes and steeper mountainsides. To the north and south, the terrain becomes increasingly rugged, with the Dachstein massif to the northeast and the Hohe Tauern range to the south. These mountain ranges create a stunning backdrop and influence the local climate and landscape. Valleys play a significant role in shaping the region's topography. The Enns River, a major tributary of the Danube, flows through the Enns Valley just north of Altenmarkt. This valley, along with smaller side valleys, provides areas of relatively flat land amidst the mountainous terrain.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The mountainous terrain presents both challenges and opportunities for solar energy development. The valley floors and gentler slopes near Altenmarkt im Pongau offer the most promise for large-scale solar PV projects. These areas typically have more consistent sun exposure throughout the day and are easier to access for construction and maintenance. The Enns Valley, in particular, could provide suitable locations for solar farms, especially on south-facing slopes that receive maximum sunlight. However, it's important to note that the surrounding mountains can cast shadows, potentially reducing the efficiency of solar panels in certain areas. Careful site selection and analysis would be crucial to maximize energy production. Higher elevation areas, while potentially offering clearer skies and less atmospheric interference, may be less practical due to difficult access and harsh weather conditions. Additionally, many of these areas are protected for their natural beauty and ecological importance, which could limit development options. In conclusion, while the topography around Altenmarkt im Pongau presents some challenges for large-scale solar PV installations, the valley areas and gentler slopes offer potential sites. Any development would need to balance energy production goals with environmental conservation and local land use considerations.
