Weingarten, Baden-Württemberg, Germany presents a moderately suitable location for solar photovoltaic energy generation, though it faces the typical challenges of Northern European locations in the temperate zone.

Seasonal Energy Production Patterns

The solar energy output at this location shows significant seasonal variation. Summer provides the strongest generation potential at 5.68 kWh per day per kilowatt of installed solar capacity, making it the ideal time for solar energy production. Spring follows as the second-best season with 4.79 kWh per day per kW, offering substantial energy generation as daylight hours increase. Autumn sees a notable decline to 2.94 kWh per day per kW, while winter presents the greatest challenge with only 1.50 kWh per day per kW. This dramatic seasonal difference means the location produces nearly four times more solar energy in summer compared to winter months. For maximum year-round energy production from a fixed panel installation at this location, solar panels should be tilted at 41 degrees facing south. This angle optimizes the total annual solar collection by accounting for the sun's varying position throughout the year.

Local Factors Affecting Solar Production

Several environmental and weather factors in this Baden-Württemberg location can significantly impact solar energy production:

• Frequent cloud cover and overcast conditions typical of the region's temperate oceanic climate
• Snow accumulation during winter months that can block panel surfaces
• High humidity and morning fog, particularly in valleys near the Bodensee region
• Potential for hail during spring and summer thunderstorms

Preventative Measures for Optimal Performance

To maximize solar energy production despite these challenges, several installation strategies should be considered. Panels should be mounted with adequate spacing to allow natural rain and wind to clear debris and snow. Installing panels at the recommended 41-degree tilt helps snow slide off more easily rather than accumulating on flat surfaces. Using high-quality tempered glass panels provides better resistance to hail damage, while anti-reflective coatings can improve performance during overcast conditions by capturing more diffuse light. Regular maintenance scheduling, particularly before and after winter, ensures panels remain clean and unobstructed. Consider installing micro-inverters or power optimizers rather than string inverters, as these can minimize production losses when individual panels are partially shaded by clouds, snow, or debris. Proper drainage around ground-mounted systems prevents water pooling that could create localized humidity issues.

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 Weingarten

Seasonal solar PV output for Latitude: 47.8093, Longitude: 9.637 (Weingarten, Germany), 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 Weingarten, Germany

To maximize your solar PV system's energy output in Weingarten, Germany (Lat/Long 47.8093, 9.637) 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 Weingarten, Germany

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 Weingarten, Germany. 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	51° 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 Weingarten, Germany

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 Weingarten, Germany.

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 Weingarten, Germany

Topographical Features of Weingarten

Weingarten sits in the rolling hills of the Upper Swabian Plateau in southwestern Germany, positioned at an elevation of approximately 450 meters above sea level. The landscape around this Baden-Württemberg town is characterized by gentle undulations and moderate slopes, typical of the moraine terrain left behind by ancient glacial activity. The area forms part of the broader Alpine Foreland, where the terrain gradually rises from the Danube valley in the north toward the foothills of the Alps to the south. The immediate surroundings feature a mix of agricultural land, scattered woodlands, and small settlements connected by winding country roads that follow the natural contours of the hills. The topography is neither mountainous nor completely flat, creating a pleasant undulating landscape with elevations varying between 400 and 550 meters across the broader region. Small valleys and ridgelines create natural drainage patterns, with several brooks and streams flowing northward toward the Danube watershed.

Soil and Land Use Patterns

The fertile soils of the region, developed on glacial deposits, have historically supported mixed agriculture including grain crops, pastureland for dairy farming, and orchards. This agricultural heritage has resulted in large open fields and meadows that remain relatively unobstructed by trees or buildings. The area's farming tradition has maintained expansive cleared areas that could potentially accommodate large-scale renewable energy installations. Traditional land use patterns have created a patchwork of fields separated by hedgerows and small copses, though many areas feature substantial continuous tracts of agricultural land. The region's economic transition from purely agricultural to more diversified activities has left some farmland available for alternative uses, particularly in areas where traditional farming has become less economically viable.

Optimal Areas for Solar Development

The most promising locations for large-scale solar photovoltaic installations would be the gently sloping agricultural fields on south and southwest-facing hillsides throughout the region. These areas combine favorable orientation with minimal shading from trees or buildings, while the moderate slopes provide natural drainage and can enhance solar collection efficiency compared to completely flat terrain. Particularly suitable areas include the open farmland extending northeast and southwest of Weingarten, where large contiguous fields offer space for substantial solar arrays. The elevated plateau areas provide good exposure while remaining accessible via existing rural road networks. The gentle topography means that ground-mounted systems would not require extensive terracing or complex foundation work that might be necessary in steeper terrain. Areas to avoid would include the steeper valley sides where installation would be more challenging and potentially less efficient, as well as the heavily wooded sections scattered throughout the region. The small settlements and their immediate surroundings would also be less suitable due to potential shading from buildings and infrastructure, along with likely planning restrictions in residential areas. The region's relatively stable geology, consisting primarily of glacial deposits over sedimentary bedrock, provides good foundation conditions for solar mounting systems. The absence of extreme topographical features such as steep cliffs, deep valleys, or unstable slopes makes most of the agricultural land technically feasible for solar development, with site selection primarily dependent on land availability, grid connection opportunities, and local planning considerations.
