Aveiras de Cima, Portugal, located at 39.1402° N, -8.8949° W, offers a promising location for solar PV energy generation throughout the year. This Northern Temperate Zone site experiences significant seasonal variations in solar energy production, which is typical for its latitude.

Seasonal Solar Energy Production

The location demonstrates a clear pattern of solar energy output across the seasons. Summer stands out as the most productive period, with an impressive 7.86 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season, generating 5.99 kWh/day. Autumn sees a moderate decrease in output at 4.22 kWh/day, while winter experiences the lowest production at 2.37 kWh/day. These figures indicate that Aveiras de Cima is particularly well-suited for solar energy generation during the warmer months, from late spring through early autumn. This period offers longer daylight hours and more direct sunlight, maximizing the potential of solar PV systems.

Optimal Panel Tilt

For fixed panel installations in Aveiras de Cima, the ideal tilt angle to maximize year-round solar production is 33 degrees facing South. This angle is calculated based on the location's latitude and seasonal sun positions, ensuring optimal exposure to sunlight throughout the year.

Environmental and Weather Considerations

While Aveiras de Cima generally presents favorable conditions for solar energy production, there are a few factors to consider: 1. Dust and pollen: The region may experience periods of increased dust or pollen in the air, which can accumulate on solar panels and reduce efficiency. 2. Occasional fog or mist: Being relatively close to the Atlantic coast, the area might experience some foggy days, particularly in cooler months. To mitigate these potential issues, consider the following preventative measures:

• Install self-cleaning panels or implement a regular cleaning schedule
• Use anti-reflective coatings on panels to improve performance in low-light conditions
• Consider a tracking system for larger installations to maximize sun exposure

Overall, Aveiras de Cima offers a good location for solar PV energy generation, with strong potential during summer and spring months. While winter output is lower, the year-round production capabilities make it a viable option for sustainable energy generation in this Portuguese locale.

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 Aveiras De Cima

Seasonal solar PV output for Latitude: 39.1402, Longitude: -8.8949 (Aveiras De Cima, Portugal), 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 33° South in Aveiras De Cima, Portugal

To maximize your solar PV system's energy output in Aveiras De Cima, Portugal (Lat/Long 39.1402, -8.8949) throughout the year, you should tilt your panels at an angle of 33° 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 Aveiras De Cima, Portugal

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 Aveiras De Cima, Portugal. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
23° South in Summer	44° South in Autumn	54° South in Winter	32° 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 Aveiras De Cima, Portugal

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 Aveiras De Cima, Portugal.

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 Aveiras De Cima, Portugal

The landscape surrounding Aveiras de Cima, Portugal, is characterized by gently rolling hills and fertile valleys typical of the Ribatejo region. This area, located approximately 50 kilometers northeast of Lisbon, features a mix of agricultural land, small forests, and scattered settlements. The terrain gradually rises from the Tagus River valley in the east towards the more elevated areas in the west. The topography of Aveiras de Cima and its vicinity is generally mild, with elevations ranging from about 20 to 150 meters above sea level. The land is primarily composed of sedimentary rocks and alluvial deposits, resulting in rich soils that support various agricultural activities, including vineyards and olive groves. Small streams and tributaries of the Tagus River crisscross the landscape, creating a network of shallow valleys and low ridges.

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 gently sloping terrain in the region provides numerous potential sites for solar farms. Areas to the south and west of Aveiras de Cima, where the land rises slightly, could be particularly suitable as they offer good exposure to sunlight throughout the day. The agricultural plains stretching eastward towards the Tagus River might also present opportunities for solar PV development. These areas are relatively flat, which simplifies construction and maintenance of solar installations. However, care must be taken to balance solar energy production with the preservation of valuable agricultural land. It's worth noting that the region experiences a Mediterranean climate with hot, dry summers and mild winters, which is generally favorable for solar energy production. The abundance of sunlight in this area makes it an attractive location for solar PV projects. When selecting specific sites for large-scale solar installations, factors such as proximity to existing power infrastructure, road access, and minimal impact on local ecosystems and communities should be considered. Additionally, areas with less productive agricultural land or brownfield sites might be prioritized to minimize disruption to food production and natural habitats. Overall, the diverse topography and climate of the region surrounding Aveiras de Cima offer promising potential for solar energy development, provided that careful planning and environmental considerations are taken into account.

Portugal solar PV Stats as a country
