Mogeiro, Paraíba, Brazil, located in the tropical region at latitude -7.267 and longitude -35.486, offers significant potential for solar energy generation throughout the year. This location benefits from the consistent sunlight patterns typical of tropical regions, where seasonal changes are primarily defined by wet and dry periods rather than dramatic temperature fluctuations. The solar energy production potential in Mogeiro demonstrates moderate seasonal variation. During spring, the location achieves its peak performance with an impressive 6.76 kWh per day for each kilowatt of installed solar capacity. Summer follows with 6.23 kWh/day, while autumn and winter show slightly reduced but still substantial outputs of 5.54 kWh/day and 5.09 kWh/day respectively.

Optimal Panel Positioning

For fixed solar panel installations in Mogeiro, Paraíba, the ideal tilt angle to maximize year-round energy production is 6 degrees facing North. This specific angle has been calculated to optimize solar capture throughout the year, accounting for the Earth's elliptical orbit and Mogeiro's tropical location.

Seasonal Considerations

Spring and summer represent the prime seasons for solar energy generation in Mogeiro, Paraíba, with their higher daily production rates. However, the relatively small variation between seasons suggests that solar remains a viable energy source year-round at this location.

Environmental and Weather Factors

The primary environmental factor that could potentially impact solar production in Mogeiro is the tropical rainfall pattern. During the wet season, increased cloud cover and precipitation may temporarily reduce solar efficiency. Additionally, higher humidity levels typical of tropical regions can lead to dust accumulation on panels, slightly reducing their effectiveness.

Preventative Measures

To maximize solar energy production in Mogeiro, Paraíba, several practical measures can be implemented:

• Regular cleaning schedules to remove dust and debris, especially during drier periods when dust accumulation is more common
• Installation of panels with high humidity tolerance and anti-soiling coatings
• Implementation of slight adjustments to the tilt angle between wet and dry seasons if using adjustable mounting systems
• Selection of inverters and equipment rated for tropical conditions
• Strategic placement to avoid any potential shading from rapid vegetation growth common in tropical environments

Overall, Mogeiro presents favorable conditions for solar energy generation with relatively consistent production potential throughout the year, making it a suitable location for solar PV installations with minimal seasonal compromise.

Solar output per kW of installed solar PV by season in Mogeiro

Seasonal solar PV output for Latitude: -7.267, Longitude: -35.486 (Mogeiro, Brazil), 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 6° North in Mogeiro, Brazil

To maximize your solar PV system's energy output in Mogeiro, Brazil (Lat/Long -7.267, -35.486) throughout the year, you should tilt your panels at an angle of 6° 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 Mogeiro, 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 Mogeiro, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
9° South in Summer	13° North in Autumn	23° North in Winter	1° 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 Mogeiro, 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 Mogeiro, 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 Mogeiro, Brazil

Mogeiro, situated in the northeastern state of Paraíba, Brazil, presents a topography characteristic of the Brazilian agreste region—a transitional zone between the humid coastal areas and the semi-arid sertão interior. The terrain around Mogeiro features gently rolling hills interspersed with shallow valleys, creating a moderately undulating landscape. Elevations in this region typically range between 400 and 600 meters above sea level, contributing to its distinct microclimate. The area exhibits characteristics of the caatinga biome, with vegetation adapted to the region's seasonal rainfall patterns. During dry periods, the landscape takes on a more arid appearance, while the rainy season brings temporary transformation with greener vegetation. This cyclical pattern influences the overall topographical appearance throughout the year.

Hydrography and Drainage

The hydrographic network around Mogeiro consists primarily of intermittent streams and small rivers that flow more vigorously during rainy periods. The region falls within the Paraíba River basin, though many local waterways remain dry for significant portions of the year. This seasonal water availability pattern has historically shaped both the natural landscape and human settlement patterns. Valley bottoms often contain alluvial soils that retain moisture longer than surrounding areas, creating micro-environments within the broader topographical context. These areas traditionally support more intensive agricultural activities compared to the drier hillsides.

Potential for Solar PV Development

For large-scale solar photovoltaic development, the gently sloping hillsides facing north (in the Southern Hemisphere) offer particularly advantageous conditions. These areas receive consistent solar radiation throughout the year and typically feature less productive agricultural land, making them prime candidates for solar installations. The relatively flat plateaus found scattered throughout the region present another promising option for solar development. These locations benefit from minimal shading issues and often have good accessibility for construction and maintenance vehicles. The stable ground conditions on these plateaus also reduce installation complexity compared to steeper or more variable terrain. Areas to the west and southwest of Mogeiro town proper demonstrate especially favorable characteristics for utility-scale solar deployment. These zones combine appropriate topographical features with proximity to existing electrical infrastructure, potentially reducing interconnection costs. The naturally cleared areas in this direction also minimize the need for vegetation removal during site preparation. Less suitable areas include the deeper valleys, especially those oriented east-west, as they receive reduced solar exposure during mornings and evenings. Similarly, locations with dense seasonal vegetation would require more extensive site preparation, increasing both environmental impact and development costs. The region's moderate elevation provides some natural cooling effect for photovoltaic panels compared to lower-lying areas in Brazil's northeast, potentially improving operational efficiency. The predominantly open landscape also benefits from natural air movement across the rolling terrain, further contributing to temperature regulation of solar installations.

Brazil solar PV Stats as a country
