Solar Energy Potential in San Carlos, Maldonado, Uruguay

San Carlos, Maldonado, Uruguay, situated in the Southern Sub Tropics at latitude -34.7919 and longitude -54.9204, presents a varied landscape for solar energy generation throughout the year. This location experiences significant seasonal fluctuations in potential solar electricity production. The seasonal solar output shows a clear pattern, with summer being the most productive season. During summer months, each kilowatt of installed solar capacity can generate approximately 7.60kWh per day. Spring follows as the second most productive season with 5.97kWh per day, while autumn yields about 4.40kWh per day. Winter represents the lowest production period with only 2.87kWh per day per kilowatt installed.

Optimal Panel Installation

For fixed solar panel installations in San Carlos, Maldonado, the ideal tilt angle to maximize year-round energy production is 30 degrees facing North. This specific angle has been calculated to optimize solar capture throughout the year, accounting for the location's position in the Southern Hemisphere.

Seasonal Considerations

The significant difference between summer and winter production (a drop of over 62%) indicates that San Carlos experiences substantial seasonal variation. This means that system sizing should carefully account for winter production shortfalls if year-round consistent energy supply is needed. The summer-spring period (approximately half the year) represents the optimal time for solar generation, with daily production exceeding 5.9kWh per kilowatt installed. During these high-production months, excess energy could potentially be stored or fed back into the grid if regulations permit.

Environmental and Weather Factors

Several environmental factors could impact solar production in San Carlos:

• Coastal salt spray may affect panel efficiency and longevity due to the location's proximity to the Atlantic Ocean. Regular cleaning and marine-grade equipment are recommended.
• Occasional strong winds from Atlantic weather systems could potentially damage improperly secured mounting systems. Reinforced mounting structures designed for coastal conditions are advisable.
• Seasonal fog and humidity may reduce solar irradiance during certain periods, particularly in transitional seasons. This is already reflected in the seasonal production figures.

To mitigate these challenges, installations should incorporate corrosion-resistant materials, secure mounting systems rated for coastal wind conditions, and slightly increased system capacity to compensate for winter production lows. Additionally, implementing a regular maintenance schedule for panel cleaning would help maintain optimal efficiency. Overall, San Carlos offers good potential for solar energy generation, particularly during summer and spring, though seasonal variation must be factored into system design and expectations.

Ideally tilt fixed solar panels 30° North in San Carlos, Uruguay

To maximize your solar PV system's energy output in San Carlos, Uruguay (Lat/Long -34.7919, -54.9204) throughout the year, you should tilt your panels at an angle of 30° 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 San Carlos, 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 San Carlos, Uruguay. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° 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	40° North in Autumn	50° 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 San Carlos, 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 San Carlos, 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 San Carlos, Uruguay

Topography Around San Carlos, Uruguay

San Carlos sits in the coastal region of southeastern Uruguay, positioned within the department of Maldonado. The topography surrounding this area is characterized by gently rolling plains that typify much of Uruguay's landscape. These undulating hills, known locally as cuchillas, create a series of low ridges and shallow valleys that extend inland from the Atlantic coast.

The immediate vicinity around San Carlos features relatively modest elevation changes, with the terrain gradually rising from sea level to heights of approximately 100 to 200 meters above sea level as one moves inland. The coastal plain near San Carlos is generally flat to gently sloping, transitioning into more pronounced rolling hills further to the north and west. This landscape is punctuated by numerous small streams and seasonal watercourses that drain toward the Atlantic Ocean.

The region's geology consists primarily of crystalline basement rocks covered by sedimentary deposits, creating stable ground conditions. The soils are typically well-drained and composed of sandy to clay-loam compositions, with some areas featuring rocky outcrops that break through the surface. Natural vegetation in the area consists mainly of temperate grasslands with scattered gallery forests along waterways.

Optimal Areas for Large-Scale Solar Development

The rolling plains extending northwest and west of San Carlos present the most favorable conditions for large-scale solar photovoltaic installations. These areas offer several key advantages, including relatively flat to gently sloping terrain that minimizes grading requirements and construction costs. The stable geological foundation provides excellent support for solar mounting systems without concern for subsidence or ground instability.

The elevated plateaus and ridge tops scattered throughout the inland areas would be particularly well-suited for solar development. These locations benefit from excellent exposure to prevailing winds, which help maintain optimal panel temperatures and improve overall system efficiency. The higher elevations also tend to experience fewer issues with ground fog and atmospheric moisture that can sometimes affect coastal areas.

Areas located 10 to 20 kilometers inland from San Carlos offer an ideal balance between accessibility and optimal conditions. These zones feature good transportation infrastructure via existing rural roads while maintaining distance from the more densely populated coastal settlements. The terrain in these inland areas typically consists of broad, gently sloping fields that would accommodate large solar arrays with minimal environmental impact.

The grassland areas northwest of San Carlos toward the interior of Maldonado department present particularly attractive opportunities. These locations feature expansive open spaces with minimal tree cover, reducing the need for vegetation clearing. The natural drainage patterns in these areas are well-established, minimizing concerns about water accumulation or erosion around solar installations.

Agricultural lands in the region, particularly those used for extensive cattle grazing, could potentially accommodate solar development through agrivoltaic approaches or land-use transitions. The existing rural electrical infrastructure in these areas would facilitate grid connections for large-scale solar projects, reducing overall development costs and complexity.
