Solar Energy Potential in Miranda do Norte, Brazil

Miranda do Norte, Brazil offers an excellent location for solar energy production, with consistently high output across all seasons of the year. Located in the tropics at latitude -3.4767 and longitude -44.4787, this site benefits from steady sunlight patterns that make it highly suitable for photovoltaic (PV) systems. The seasonal solar production data shows remarkable consistency, with daily energy generation per kilowatt of installed capacity ranging from 5.32kWh in summer to 6.01kWh in spring. This represents less than 15% variation between seasons, which is significantly better than locations at higher latitudes where winter production often drops dramatically.

Seasonal Performance

Spring stands out as the peak production period with 6.01kWh per day per installed kilowatt, closely followed by winter at 5.83kWh and autumn at 5.74kWh. Summer, interestingly, shows the lowest output at 5.32kWh, though this figure still represents excellent production capacity. For fixed solar panel installations in Miranda do Norte, the ideal tilt angle to maximize year-round energy production is 4 degrees facing North. This near-horizontal orientation reflects the location's proximity to the equator, where the sun passes almost directly overhead throughout much of the year.

Environmental Considerations

Several environmental factors could potentially impact solar production at this location:

• Heavy rainfall during the wet season may reduce solar efficiency due to cloud cover and potential panel soiling
• High humidity levels can slightly decrease panel efficiency and potentially accelerate degradation of system components
• Dust accumulation during dry periods could gradually reduce panel efficiency if not addressed

Mitigation Strategies

To maximize energy production despite these challenges, several preventative measures can be implemented: Installing automated cleaning systems or implementing regular manual cleaning schedules can prevent dust and dirt accumulation. Using high-quality, humidity-resistant components with proper sealing will extend system lifespan in this tropical environment. Additionally, slightly increasing the tilt angle beyond the optimal 4 degrees can facilitate natural cleaning during rainfalls. Overall, Miranda do Norte presents an exceptionally favorable location for solar energy production, with consistently high output throughout the year and manageable environmental challenges that can be addressed through proper system design and maintenance.

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

Ideally tilt fixed solar panels 4° North in Miranda Do Norte, Brazil

To maximize your solar PV system's energy output in Miranda Do Norte, Brazil (Lat/Long -3.4767, -44.4787) throughout the year, you should tilt your panels at an angle of 4° 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 Miranda Do Norte, 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 Miranda Do Norte, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 4° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
12° South in Summer	10° North in Autumn	19° North in Winter	2° 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 Miranda Do Norte, 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 Miranda Do Norte, 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 Miranda Do Norte, Brazil

Miranda do Norte is situated in the northeastern part of Brazil, specifically in the state of Maranhão. The topography of the region is characterized by gently rolling hills and plains, typical of the transition zone between the Amazon basin and the more arid northeastern regions of Brazil. The area has an average elevation of approximately 40 meters above sea level, with modest variations throughout the surrounding landscape. The terrain around Miranda do Norte consists primarily of tropical savanna vegetation, locally known as "cerrado," interspersed with patches of tropical forest. This vegetation pattern reflects the region's position in the ecological transition zone. The landscape has been significantly modified by human activities, with substantial areas converted to agricultural use and pasture lands.

Hydrological Features

The region is part of the Mearim River basin, with several smaller tributaries flowing through the area. These waterways have shaped the local topography, creating gentle valleys and occasional floodplains. During the rainy season, some low-lying areas may experience temporary flooding, which should be considered when planning any large-scale infrastructure projects.

Suitable Areas for Solar PV Development

For large-scale solar photovoltaic development, the most suitable areas near Miranda do Norte would be the elevated plateaus and gently sloping hillsides that are abundant in the region. These areas offer several advantages for solar installation: The slightly elevated terrain reduces the risk of flooding during the rainy season, which is crucial for protecting solar infrastructure. Additionally, these higher areas typically have less vegetation coverage, minimizing the need for extensive land clearing. The northeastern and eastern regions of Miranda do Norte, extending toward the neighboring municipality of Itapecuru Mirim, present particularly favorable conditions. These areas feature more open terrain with fewer dense forest patches, making them more accessible for development while minimizing environmental impact.

Terrain Considerations

The soil composition in the region consists primarily of latosols and argisols, which generally provide stable ground conditions for mounting solar panel structures. However, site-specific geotechnical studies would be necessary before any large-scale development. The modest topographical relief around Miranda do Norte is actually advantageous for solar PV installation, as it reduces the complexity and cost of site preparation. The gentle slopes also facilitate natural drainage, which helps prevent water accumulation around solar infrastructure.

Land Use Patterns

Current land use in the region is dominated by small-scale agriculture, cattle ranching, and scattered settlements. There are substantial areas of disturbed or already-cleared land that could be repurposed for solar energy production, potentially minimizing additional environmental impacts. The western periphery of Miranda do Norte, where the terrain transitions to slightly more elevated areas, offers a good balance of favorable topography and proximity to existing infrastructure, including access to the BR-135 highway and the regional electrical grid, making it particularly suitable for large-scale solar development.

Brazil solar PV Stats as a country
