Fray Marcos, Florida, Uruguay, situated at latitude -34.1973 and longitude -55.7319 in the Southern Sub Tropics, offers varying potential for solar PV energy generation throughout the year. This location experiences significant seasonal fluctuations in solar electricity production that prospective solar installers should consider.

Seasonal Solar Production

The solar energy output at Fray Marcos shows a clear seasonal pattern. Summer months are the most productive, generating approximately 7.80 kWh per day for each kilowatt of installed capacity. Spring follows as the second most productive season with 6.29 kWh/day per kW installed. Autumn yields moderate production at 4.53 kWh/day, while winter months drop significantly to just 3.12 kWh/day per kW of installed solar capacity.

This seasonal variation means that Fray Marcos residents can expect more than double the solar energy production in summer compared to winter months. The substantial difference highlights the importance of proper system sizing to ensure adequate year-round energy supply, especially if the installation is intended to provide a significant portion of a household's or business's electricity needs.

Optimal Panel Installation

For fixed solar panel installations in Fray Marcos, Florida, the ideal tilt angle to maximize year-round energy production is 29 degrees facing North. This angle has been calculated specifically for this location to optimize annual solar energy capture, taking into account the Earth's elliptical orbit and the site's particular latitude.

Environmental and Weather Considerations

Several environmental factors could potentially impact solar production in Fray Marcos:

• Occasional dust storms and agricultural activities in this rural region may deposit dirt on panels, reducing efficiency if not regularly cleaned.
• The subtropical climate brings seasonal heavy rainfall, particularly in spring and summer, which can temporarily reduce solar output during storm events.
• Morning fog, common in certain seasons near river valleys in this region, may delay peak production hours on some days.

To mitigate these challenges, solar installations in Fray Marcos should incorporate several preventative measures. Regular panel cleaning should be scheduled, especially after dusty periods. Installing panels at the recommended 29-degree tilt not only optimizes production but also facilitates natural cleaning during rainfall. Additionally, quality inverters with good low-light performance can help maximize energy harvest during foggy mornings or partially cloudy days.

Overall, while Fray Marcos isn't ideal for consistent year-round solar production due to its significant winter drop-off, the location still offers good annual solar potential, especially if systems are properly designed with seasonal variations in mind.

Ideally tilt fixed solar panels 29° North in Fray Marcos, Uruguay

To maximize your solar PV system's energy output in Fray Marcos, Uruguay (Lat/Long -34.1973, -55.7319) throughout the year, you should tilt your panels at an angle of 29° North 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 Fray Marcos, Uruguay

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 Fray Marcos, Uruguay. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
18° North in Summer	39° North in Autumn	49° North in Winter	27° North 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 Fray Marcos, Uruguay

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 Fray Marcos, Uruguay.

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 Fray Marcos, Uruguay

The landscape surrounding Fray Marcos, Uruguay presents a gently undulating topography characterized by rolling hills and shallow valleys typical of this region of central Uruguay. Located in the Florida Department, the terrain consists primarily of low, rounded hills interspersed with small streams and minor watercourses that have carved subtle depressions throughout the landscape. The elevation generally ranges between 100 and 200 meters above sea level, creating a moderately varied terrain without extreme features. The area forms part of Uruguay's peneplain - a nearly flat surface produced by long periods of erosion - with exposed granitic and metamorphic basement rocks occasionally visible. The soils are predominantly well-drained and of moderate fertility, supporting the region's traditional agricultural activities of cattle ranching and some crop cultivation.

Hydrological Features

Several small rivers and streams traverse the region, including tributaries that eventually connect to the Río Santa Lucía watershed. These waterways have shaped the local topography over geological time, creating gentle valleys between the rolling hills. During seasonal rains, these watercourses can swell, but significant flooding is relatively rare due to the moderate relief of the terrain.

Vegetation and Land Use

The natural vegetation consists mainly of temperate grasslands (pampa), though much has been modified for agricultural purposes. Trees are scattered throughout the landscape, with denser groupings along watercourses and in areas less suitable for agriculture. The predominant land use is livestock grazing, with some areas dedicated to crop production, particularly soybeans, wheat, and other cereals.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic development, the most suitable areas near Fray Marcos would be the gently sloping hillsides with southern to northern exposures, which receive consistent sunlight throughout the day. Specifically, the slightly elevated plateaus and hill crests approximately 3-5 kilometers to the north and northeast of Fray Marcos offer ideal conditions due to their minimal shadowing effects and good drainage characteristics. These areas benefit from relatively flat to gently sloping terrain that requires minimal grading for installation, reducing construction costs and environmental impact. The soil stability in these locations is generally good, providing solid foundations for mounting structures without excessive engineering requirements. Additionally, the moderately elevated areas approximately 7 kilometers to the northwest present favorable conditions, with open expanses that experience minimal obstructions from natural features. These locations also tend to have fewer competing land uses, as they are often less optimal for intensive agriculture due to their slightly elevated position and exposure to prevailing winds. Areas to avoid would include the riparian zones along streams and rivers, low-lying areas susceptible to seasonal pooling of water, and the steeper hillsides that would require significant earthworks to prepare for installation. The southeastern lowlands, while flat, may experience occasional water accumulation during heavy rainfall events, potentially complicating maintenance and operations.
