Solar Energy Potential in Amontada, Ceará, Brazil
Amontada, Ceará, Brazil, situated at latitude -3.2758 and longitude -39.8061, presents a highly favorable location for solar energy generation throughout the year. This tropical location benefits from consistent sunlight patterns, with weather patterns defined more by wet and dry seasons rather than traditional temperature-based seasons. The solar energy production potential in Amontada shows impressive consistency across meteorological seasons. During summer, solar panels can generate approximately 5.94 kWh per day for each kilowatt installed. Autumn production drops slightly to 5.68 kWh/day, while winter sees an increase to 6.19 kWh/day. The most productive season is spring, with an outstanding 7.11 kWh/day production capacity. For fixed solar panel installations in Amontada, Ceará, the ideal tilt angle to maximize year-round energy production is 3 degrees North. This slight tilt helps optimize solar capture throughout the year, accounting for the location's proximity to the equator and the sun's position in the sky throughout the seasons.Seasonal Variations and Optimal Production Periods
Spring stands out as the peak production period in Amontada, Ceará, with its 7.11 kWh/day generation capacity significantly higher than other seasons. This makes March through May particularly valuable months for solar energy harvesting. Winter follows as the second most productive season, suggesting that even during what might typically be considered less ideal periods in other regions, Amontada maintains strong solar potential. The relatively small variation between the highest and lowest producing seasons (a difference of only 1.43 kWh/day between spring and autumn) indicates exceptional year-round consistency. This consistency makes Amontada an ideal location for solar PV installations that aim to provide reliable power throughout the year without significant seasonal dropoffs.Environmental Considerations and Mitigation Strategies
Despite the favorable conditions, some environmental factors may affect solar production in Amontada:- Seasonal rainfall patterns during the wet season can temporarily reduce solar output due to cloud cover and precipitation. Installing slightly larger systems can help compensate for these predictable reductions.
- Coastal proximity may expose panels to salt spray and humidity, potentially accelerating corrosion. Using marine-grade components and protective coatings can significantly extend system lifespan.
- Dust accumulation during dry seasons can gradually reduce panel efficiency. Implementing regular cleaning schedules or automated cleaning systems helps maintain optimal performance.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 3° North in Amontada, Brazil
To maximize your solar PV system's energy output in Amontada, Brazil (Lat/Long -3.2758, -39.8061) throughout the year, you should tilt your panels at an angle of 3° 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 Amontada, 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 Amontada, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 3° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° South in Summer | 10° North in Autumn | 19° North in Winter | 3° 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 Amontada, 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 Amontada, 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 Amontada, Brazil
The terrain surrounding Amontada, Brazil, is characterized by a diverse topography that transitions from coastal plains to more undulating inland areas. Located in the state of Ceará in northeastern Brazil, Amontada sits relatively close to the Atlantic Ocean, with coastal features dominating its northern regions. Near the coast, the landscape consists primarily of flat to gently rolling sandy plains. These coastal lowlands feature scattered vegetation adapted to the semi-arid climate, interspersed with dunes and sandy soil. Moving inland from the shore, the terrain gradually rises into low hills and plateaus that rarely exceed 200 meters in elevation.
Coastal Features
The northern portion of the Amontada region includes beaches and coastal formations where the land meets the Atlantic Ocean. These areas have relatively level terrain with sandy soils and are sometimes punctuated by small lagoons and estuaries. The Rio Aracatiaçu flows through the region, creating riparian zones that contrast with the surrounding drier landscapes.Inland Topography
As one moves further inland and south from Amontada, the landscape becomes more varied, with gently rolling hills and occasional plateaus. The vegetation transitions to caatinga, a type of dry forest and scrubland typical of Brazil's northeastern interior. The terrain in these areas features more rocky outcroppings and slightly higher elevations compared to the coastal plains.Potential for Solar PV Development
For large-scale solar photovoltaic installations, the inland areas south and southwest of Amontada present particularly favorable conditions. These regions combine several advantageous characteristics: The gently sloping terrain provides good drainage while minimizing the need for extensive land grading. The slightly elevated plateaus often have minimal shading from natural features, allowing for maximum solar exposure throughout the day. Additionally, these inland areas typically have less agricultural activity than the coastal zones, potentially reducing land-use conflicts. The semi-arid nature of the region means vegetation is generally sparse and low-growing, requiring minimal clearing for solar installations. The stable geological foundation of these inland plateaus also offers solid ground for mounting structures without excessive foundation work. Areas approximately 10-30 kilometers inland from Amontada proper strike a particularly good balance between favorable topography, land availability, and proximity to existing infrastructure. These zones feature relatively flat terrain with slight southern exposures in some locations, which can optimize solar panel orientation in the northern hemisphere. The western portions of the municipality, where the terrain becomes slightly more elevated but remains accessible, would also be well-suited for solar development, offering good exposure with minimal topographical obstacles that might otherwise create shading issues.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]
Are there incentives for businesses to install solar in Brazil?
