Solar Energy Potential in Nobres, Mato Grosso, Brazil

Nobres, Mato Grosso, Brazil, located at latitude -14.5798 and longitude -55.7148, offers excellent potential for solar energy production throughout the year. This tropical location benefits from consistent sunlight patterns and relatively minor seasonal variations in solar energy output. The solar production data shows remarkable consistency across all meteorological seasons. During summer, each kilowatt of installed solar capacity generates about 5.95 kWh per day. Autumn sees a slight decrease to 5.68 kWh per day. Winter production rebounds to 5.90 kWh per day, while spring offers the highest output at 5.99 kWh per day. This minimal seasonal variation (less than 6% difference between the highest and lowest producing seasons) makes Nobres an ideal location for year-round solar energy harvesting. Spring and summer emerge as the marginally better seasons for solar production, though the difference is not dramatic enough to consider the location as having distinct "peak" periods. For fixed solar panel installations in Nobres, Mato Grosso, the ideal tilt angle is 15 degrees facing North. This specific angle has been calculated to maximize total year-round energy production based on the location's latitude and solar elevation patterns throughout the year.

Potential Challenges and Mitigation Strategies

Despite the favorable conditions, several environmental factors could potentially impact solar production in Nobres:
  • Heavy rainfall during the wet season (typically October to April) may temporarily reduce solar output due to cloud cover and direct rain on panels.
  • Dust accumulation, particularly during the dry season, can gradually diminish panel efficiency if not addressed.
  • Higher temperatures in this tropical region can slightly reduce photovoltaic efficiency, as solar panels typically perform better in cooler conditions.
To mitigate these challenges, solar installations in Nobres should incorporate several preventative measures. Regular cleaning schedules should be implemented, particularly before and after the rainy season. Self-cleaning panel technologies or hydrophobic coatings can be beneficial. Adequate panel spacing and elevated mounting can improve air circulation, helping to mitigate efficiency losses from high temperatures. Installing a monitoring system to track performance variations can help identify when maintenance is needed. Additionally, slightly increasing the total installed capacity can compensate for occasional production dips during particularly cloudy periods of the wet season. Overall, Nobres presents near-ideal conditions for solar energy production with its consistent year-round solar resource, requiring only standard tropical-climate adaptations to maximize energy harvest.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 15° North in Nobres, Brazil

To maximize your solar PV system's energy output in Nobres, Brazil (Lat/Long -14.5798, -55.7148) throughout the year, you should tilt your panels at an angle of 15° 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 Nobres, Brazil

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 Nobres, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° North tilt angle throughout the year.

Overall Best Summer Angle Overall Best Autumn Angle Overall Best Winter Angle Overall Best Spring Angle
1° South in Summer 21° North in Autumn 30° North in Winter 9° North in Spring

Assuming you can modify the tilt angle of your solar PV panels throughout the year, you can optimize your solar generation in Nobres, Brazil as follows: In Summer, set the angle of your panels to 1° facing South. In Autumn, tilt panels to 21° facing North for maximum generation. During Winter, adjust your solar panels to a 30° angle towards the North for optimal energy production. Lastly, in Spring, position your panels at a 9° angle facing North to capture the most solar energy in Nobres, Brazil.

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 Nobres, Brazil

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 Nobres, Brazil.

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 Nobres, Brazil

The topography around Nobres, Brazil presents a diverse landscape characterized by a transition between the Amazon Basin and the Brazilian Central Plateau. Located in the state of Mato Grosso, this region features a mix of gently rolling hills, flat plains, and some more pronounced elevations. The terrain is predominantly composed of sedimentary formations, with limestone being particularly notable in the area, giving rise to striking karst features including caves, sinkholes, and crystal-clear springs. The municipality sits at an average elevation of approximately 200 meters above sea level, though this varies throughout the region. To the east of Nobres, the terrain gradually rises toward the Chapada dos Guimarães, a significant plateau formation with escarpments and tablelands that can reach heights of over 800 meters. This eastern area features more rugged topography with some steep slopes and plateaus.

Hydrological Features

The region is notably rich in water resources, with the Cuiabá River and its tributaries flowing through the area. These waterways have shaped the landscape over millennia, creating fertile valleys between the elevated areas. The abundance of water has also contributed to the formation of wetland areas in lower elevations, particularly during the rainy season when some plains may experience temporary flooding. The western portions of the Nobres region transition toward the Pantanal, the world's largest tropical wetland area, where the topography becomes increasingly flat and susceptible to seasonal inundation. This gradual flattening of the landscape is a key characteristic of the regional topography.

Vegetation and Land Cover

The natural vegetation reflects the transitional character of the region, with areas of cerrado (Brazilian savanna) interspersed with patches of tropical forest. In many places, the original vegetation has been altered by human activities, particularly cattle ranching and agriculture, creating a mosaic of natural and modified landscapes.

Solar PV Potential Areas

For large-scale solar photovoltaic development, the most suitable areas near Nobres would be the elevated plateaus and gently sloping plains that are not subject to flooding. The flat to slightly undulating terrain to the northeast and east of Nobres, extending toward the Chapada dos Guimarães, offers particularly promising conditions for solar installations. These elevated areas benefit from minimal shadowing effects due to their open exposure and limited tall vegetation. The plateaus also typically experience less cloud cover compared to the lower-lying areas near rivers and wetlands, which can experience morning fog and higher humidity. The northwestern sectors beyond the immediate vicinity of Nobres also present favorable topography for solar development, with extensive areas of relatively flat terrain that has already been cleared for agricultural use. These areas combine good solar exposure with existing access to infrastructure, including roads that connect to major transportation networks. Areas to avoid would include the limestone karst formations, which can be environmentally sensitive and present construction challenges, as well as the low-lying regions to the west that may be subject to seasonal flooding. The steeper slopes of the eastern escarpments, while receiving good solar radiation, would present engineering challenges and potentially higher installation costs compared to more level terrain. The combination of favorable topography, existing land use patterns, and proximity to transmission infrastructure makes the plateaus and higher plains surrounding Nobres particularly attractive for large-scale solar PV development, with the northeastern sector offering perhaps the most optimal balance of these factors.

Brazil solar PV Stats as a country
