Cedro, Brazil presents an excellent location for year-round solar energy generation, with consistently high electricity output throughout all seasons. Located in the tropical region at coordinates -7.7197, -39.233, this area benefits from the stable sunlight patterns typical of equatorial zones.
Seasonal Solar Performance
The solar energy output at Cedro remains remarkably consistent across the year, with only modest seasonal variations. Summer produces 5.83 kWh per day per kW of installed solar capacity, while autumn shows a slight improvement at 5.87 kWh/day. Winter maintains strong performance at 5.99 kWh/day per kW installed. Spring emerges as the optimal season for solar generation, delivering an impressive 7.27 kWh per day per kW of installed capacity. This represents a 25% increase over the lowest-performing season, making spring the ideal time for maximum solar energy harvest at this location.Optimal Panel Configuration
For fixed panel installations at Cedro, the ideal tilt angle is 8 degrees North to maximize total year-round solar production. This relatively shallow angle reflects the location's proximity to the equator, where the sun maintains a high position in the sky throughout the year.Environmental Factors and Mitigation Strategies
Several environmental factors could potentially impact solar production at this tropical Brazilian location:- Dust and debris accumulation - The dry season can bring significant dust buildup on panels, reducing efficiency
- Heavy rainfall during wet season - While rain can clean panels naturally, intense storms may cause temporary shading from cloud cover
- High humidity levels - Tropical humidity can affect electrical connections and panel performance over time
- Vegetation growth - Rapid plant growth in tropical climates can create shading issues if not managed
Preventative Measures
To ensure optimal solar energy production, several installation strategies should be implemented:- Regular cleaning schedule - Establish monthly panel cleaning during dry periods to remove dust accumulation
- Proper drainage systems - Install adequate drainage around panel arrays to handle heavy tropical rainfall
- Moisture-resistant components - Use high-quality, humidity-resistant electrical connections and mounting hardware
- Vegetation management - Maintain clear zones around solar installations and trim vegetation regularly to prevent shading
- Elevated mounting - Position panels with adequate ground clearance to improve air circulation and reduce humidity effects
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 Cedro, Pernambuco
Seasonal solar PV output for Latitude: -7.7197, Longitude: -39.233 (Cedro, Pernambuco, 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 8° North in Cedro, Pernambuco, Brazil
To maximize your solar PV system's energy output in Cedro, Pernambuco, Brazil (Lat/Long -7.7197, -39.233) throughout the year, you should tilt your panels at an angle of 8° 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 Cedro, Pernambuco, 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 Cedro, Pernambuco, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° South in Summer | 14° North in Autumn | 23° North in Winter | 2° 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 Cedro, Pernambuco, 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 Cedro, Pernambuco, 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 Cedro, Pernambuco, Brazil
Topographical Features of the Cedro Region
The area surrounding Cedro, Brazil is characterized by the distinctive landscape of the Caatinga biome, which dominates much of the northeastern interior of the country. This semi-arid region features gently rolling hills and broad valleys, with elevations typically ranging from 200 to 600 meters above sea level. The terrain is generally undulating rather than mountainous, creating a landscape of modest slopes and relatively open expanses.
The local topography is shaped by ancient geological formations, primarily consisting of crystalline basement rocks that have been weathered over millions of years. This has resulted in a terrain that features scattered inselbergs - isolated rocky hills that rise abruptly from the surrounding plains. These granite and gneiss outcrops create distinctive landmarks across the landscape, while the intervening areas consist of gentler slopes covered with thin soils.
Water courses in the region are typically seasonal, flowing only during the rainy period and remaining dry for much of the year. These intermittent streams have carved shallow valleys and depressions across the landscape, creating a network of natural drainage channels that influence the local topography. The overall relief is moderate, with most slopes being gradual enough to allow for various land uses while still providing adequate drainage.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be the broad, gently sloping plateaus and valley floors that characterize much of the region around Cedro. These areas offer the ideal combination of relatively flat terrain, good drainage, and minimal shading from topographical features. The gentle slopes, typically ranging from 1 to 5 degrees, provide excellent conditions for solar panel installation while allowing for proper water runoff during rainfall events.
The elevated plains between the scattered rocky outcrops represent particularly favorable sites for solar development. These areas typically feature stable ground conditions with bedrock relatively close to the surface, reducing foundation costs and providing solid anchoring for solar mounting systems. The open nature of these plateaus also minimizes shading concerns and allows for flexible array layouts to maximize energy capture throughout the day.
Areas to avoid for large-scale installations would include the steeper slopes of the inselbergs themselves, narrow valley bottoms prone to seasonal flooding, and locations with significant rock outcroppings that would complicate construction. The seasonal drainage channels, while generally shallow, should also be avoided to prevent potential flood damage and to maintain natural water flow patterns.
The region's relatively consistent topography across large areas makes it well-suited for extensive solar farms, as developers can find substantial tracts of similarly oriented land without significant variations in slope or aspect. This uniformity simplifies both the design and construction phases of large-scale solar projects, while the stable geological conditions provide a solid foundation for long-term installations.
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.
