Muribeca, Sergipe, Brazil represents an excellent location for year-round solar energy generation, benefiting from its tropical position where consistent sunlight is available throughout most of the year, with seasons typically defined by wet and dry periods rather than significant temperature variations.
Solar Energy Output Performance
The solar energy production data for this location shows strong performance across all seasons. Spring delivers the highest output at 7.23 kWh per day per kW of installed solar capacity, followed closely by summer at 7.06 kWh per day. Even during the lowest-producing season of winter, the location still generates a respectable 5.37 kWh per day per kW, while autumn produces 6.07 kWh per day per kW. This consistent performance throughout the year makes Muribeca particularly attractive for solar installations, as there are no extended periods of dramatically reduced energy production that might occur in higher latitude locations.Optimal Panel Configuration
For maximum year-round energy production at this location, solar panels should be installed at a fixed tilt angle of 9 degrees facing north. This relatively shallow angle is calculated to optimize total annual solar output by accounting for the sun's path throughout the year, daily solar elevation angles, and weighting based on solar irradiance data that considers Earth's elliptical orbit.Environmental and Weather Challenges
Several local factors could potentially impact solar energy production in Muribeca and require careful consideration during installation:- High humidity and rainfall: The tropical climate brings significant moisture, particularly during wet seasons, which can lead to increased soiling of panels and potential corrosion of equipment
- Salt air exposure: Being located near the coast, salt-laden air can accelerate corrosion of metal components and reduce panel efficiency over time
- Intense UV radiation: The tropical location means panels and mounting systems face particularly harsh ultraviolet exposure year-round
- Heavy rainfall events: Tropical downpours can be intense and may impact mounting system stability if not properly designed
Preventative Measures for Optimal Performance
To ensure maximum energy production despite these environmental challenges, several protective measures should be implemented:- Marine-grade materials: Use corrosion-resistant aluminum or stainless steel mounting systems specifically rated for coastal environments
- Enhanced drainage design: Install panels with adequate spacing and drainage channels to handle heavy rainfall and prevent water accumulation
- Regular maintenance schedule: Implement frequent cleaning protocols to remove salt buildup and debris, particularly after heavy rain periods
- Quality panel selection: Choose panels with robust anti-reflective coatings and frames designed to withstand high humidity and UV exposure
- Proper ventilation: Ensure adequate airflow around panels to prevent overheating and moisture buildup that could reduce efficiency
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Muribeca
Seasonal solar PV output for Latitude: -10.3881, Longitude: -36.9799 (Muribeca, 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 9° North in Muribeca, Brazil
To maximize your solar PV system's energy output in Muribeca, Brazil (Lat/Long -10.3881, -36.9799) throughout the year, you should tilt your panels at an angle of 9° 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 Muribeca, 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 Muribeca, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 9° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° South in Summer | 16° North in Autumn | 26° North in Winter | 4° 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 Muribeca, 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 Muribeca, Brazil.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Muribeca, Brazil
The topography around Muribeca in Brazil is characterized by relatively flat to gently rolling terrain typical of the coastal plains region of Sergipe state. This area sits within the Atlantic coastal lowlands, where elevations are generally modest and the landscape consists primarily of sedimentary formations that have been shaped by both marine and fluvial processes over geological time. The immediate vicinity of Muribeca features predominantly level ground with occasional low hills and shallow valleys. The terrain slopes very gradually toward the Atlantic Ocean, which lies approximately 15 kilometers to the east. This gentle gradient creates natural drainage patterns that flow eastward toward the coast, with small streams and seasonal watercourses meandering through the landscape. Moving inland from Muribeca toward the west and northwest, the topography begins to show slightly more variation as it transitions into the interior tablelands. These areas feature broader undulations and occasional mesa-like formations, though still maintaining relatively modest elevation changes. The soils in this region are typically well-drained and consist of sandy to clay-loam compositions derived from sedimentary parent materials.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations would be found on the expansive flat to gently sloping areas that extend westward and northwestward from Muribeca. These zones offer several key advantages including minimal grading requirements, reduced construction costs, and optimal solar panel positioning potential. The broad plateaus and mesa tops located 10 to 25 kilometers west of Muribeca present particularly attractive development opportunities. These elevated but relatively flat surfaces provide excellent drainage, reducing concerns about water accumulation around solar installations during the rainy season. The stable geological conditions in these areas also minimize foundation challenges for large solar arrays. Areas to the southwest of Muribeca, where the terrain opens into wider valleys and plains, would also be well-suited for solar development. The natural topography in these locations requires minimal earthwork while providing sufficient space for extensive solar farms. The gentle slopes in these areas can actually be beneficial for solar installations, as they can be oriented to maximize solar exposure while facilitating natural runoff management. The coastal plain areas closer to the Atlantic, while topographically suitable, may present challenges related to salt air exposure and higher humidity levels that could affect long-term equipment performance. Therefore, the inland locations with their drier conditions and stable terrain represent the most practical choices for major solar installations in the Muribeca region.Brazil solar PV Stats as a country
Brazil ranks 13th in the world for cumulative solar PV capacity, with 13,708 total MW's of solar PV installed. This means that 2.50% of Brazil's total energy as a country comes from solar PV (that's 31st in the world). Each year Brazil is generating 64 Watts from solar PV per capita (Brazil ranks 47th in the world for solar PV Watts generated per capita). [source]
