Moudon, Vaud, Switzerland, situated at 46.6679° N, 6.7982° E, presents a mixed picture for solar PV energy generation throughout the year. This location in the Northern Temperate Zone experiences significant seasonal variations in solar output, which impacts the overall efficiency of solar installations.

Seasonal Solar Performance

Summer stands out as the most productive season, with an impressive 6.00 kWh per day output for each kW of installed solar capacity. Spring follows as the second-best season, generating 4.89 kWh per day. Autumn sees a notable decrease to 3.09 kWh per day, while winter performance drops dramatically to just 1.58 kWh per day.

These figures indicate that solar energy production in Moudon is highly seasonal. The long, sunny days of summer provide excellent conditions for solar generation, making it an ideal time for maximizing energy output. Spring and autumn offer moderate productivity, while winter presents significant challenges due to shorter days and potentially overcast conditions.

Optimizing Solar Panel Installation

To maximize year-round solar energy production in Moudon, Vaud, fixed solar panels should be installed at a tilt angle of 40 degrees facing south. This optimal angle helps capture the most sunlight throughout the year, balancing the varying sun positions across seasons.

Environmental and Weather Considerations

While Moudon's location is generally favorable for solar energy, there are some environmental factors to consider:

1. Snow: Winter snowfall can temporarily reduce panel efficiency by covering them. Installing panels at the optimal angle helps snow slide off more easily.
2. Fog: The nearby Broye River may contribute to morning fog, potentially reducing early day production. Elevating panels can help mitigate this issue.
3. Tree cover: Surrounding vegetation might cast shadows on panels. Careful placement and regular trimming can minimize this impact.

To address these factors, consider using snow-shedding panel frames, implementing a robust cleaning schedule, and ensuring proper panel placement to avoid shading. Additionally, using high-efficiency panels can help maximize production during less ideal conditions.

In conclusion, while Moudon's location presents challenges, particularly in winter, it still offers good potential for solar energy generation, especially during the spring and summer months. With proper installation and maintenance, solar PV systems can be a viable source of renewable energy in this Swiss town.

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

Seasonal solar PV output for Latitude: 46.6679, Longitude: 6.7982 (Moudon, Switzerland), 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 Moudon, Switzerland

To maximize your solar PV system's energy output in Moudon, Switzerland (Lat/Long 46.6679, 6.7982) 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 Moudon, Switzerland

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 Moudon, Switzerland. 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
30° 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 Moudon, Switzerland

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 Moudon, Switzerland.

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 Moudon, Switzerland

The area surrounding Moudon, Switzerland, nestled in the heart of the canton of Vaud, is characterized by a diverse and picturesque topography. This charming region is situated in the Swiss Plateau, a relatively flat area between the Jura Mountains to the northwest and the Swiss Alps to the southeast. However, the landscape around Moudon is far from monotonous. The town itself is built on a small hill overlooking the Broye River, which meanders through the valley. The immediate vicinity of Moudon features gently rolling hills and small plateaus, creating a patchwork of agricultural fields, pastures, and wooded areas. These undulating terrains gradually give way to more pronounced elevations as one moves away from the town center. To the east and west of Moudon, the landscape becomes more varied, with steeper hillsides and deeper valleys. These areas are often covered in lush forests, particularly on the north-facing slopes. The southern-facing hillsides tend to be more open, sometimes featuring vineyards or orchards that take advantage of the increased sunlight exposure.

Potential for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine ample sunlight exposure, minimal shading, and relatively flat or gently sloping terrain to simplify installation and maintenance. The most promising areas for solar PV development near Moudon would likely be the open, south-facing slopes and plateaus to the south and southwest of the town. These areas generally receive more direct sunlight throughout the day and year due to their orientation. Additionally, the gentler gradients of these hillsides make them more suitable for the installation of large solar arrays. Agricultural lands on the broader, flatter areas of the Swiss Plateau surrounding Moudon could also be considered for solar PV projects. However, this would need to be balanced with the region's agricultural needs and land-use regulations. Some farmers in the area have already begun experimenting with agrivoltaics, a system that combines solar panel installation with crop cultivation or livestock grazing underneath. It's important to note that while the topography around Moudon offers potential for solar energy development, any large-scale projects would need to be carefully planned to minimize environmental impact and preserve the scenic beauty of this Swiss landscape. Additionally, local regulations, grid connectivity, and community acceptance would all play crucial roles in determining the feasibility and location of any significant solar PV installations in the region.
