Currais Novos, Rio Grande do Norte, Brazil, located at latitude -6.2106 and longitude -36.4817, presents a favorable location for solar PV energy generation throughout the year. This tropical location benefits from relatively consistent sunlight patterns across seasons, though with some notable variations. The seasonal solar production shows promising output throughout the year. Spring stands out as the most productive season with an impressive 7.29 kWh per day for each kilowatt of installed solar capacity. Summer follows with 6.59 kWh/day, while autumn yields 6.14 kWh/day. Winter, though slightly lower, still delivers a substantial 5.73 kWh/day per kW of installed capacity.Optimal Panel Installation
For fixed solar panel installations in Currais Novos, Rio Grande do Norte, the ideal tilt angle to maximize year-round energy production is 5 degrees facing North. This slight tilt optimizes exposure to the sun's path across the sky throughout the year, accounting for the location's proximity to the equator where the sun passes nearly overhead.Seasonal Considerations
The data reveals that spring months offer the greatest solar potential in Currais Novos, Rio Grande do Norte, with production approximately 27% higher than during winter months. This pattern suggests that system owners might expect peak production during spring, with a gradual decline through summer and autumn, reaching the lowest output during winter months.Environmental and Weather Factors
Several environmental factors could potentially impact solar production in Currais Novos:- Dust accumulation: The semi-arid climate of Brazil's northeastern region can lead to significant dust buildup on panels, reducing efficiency by 10-30% if not addressed.
- Seasonal rainfall patterns: While rain can naturally clean panels, the region's distinct wet and dry seasons mean panels may require manual cleaning during extended dry periods.
- High temperatures: Excessive heat can reduce solar panel efficiency. The tropical location experiences high temperatures that may diminish performance during peak heat hours.
Preventative Measures
To maximize solar production in Currais Novos, Rio Grande do Norte, consider these preventative measures:- Implement regular cleaning schedules, especially during dry seasons when dust accumulation is highest
- Install panels with sufficient spacing and elevation to allow for natural air circulation, reducing temperature-related efficiency losses
- Consider self-cleaning panel technologies or hydrophobic coatings that minimize dust adhesion
- Install monitoring systems to quickly identify any unexpected drops in production that might indicate dust buildup or other issues
- Schedule major maintenance during winter months when production is naturally lower to minimize lost generation

Ideally tilt fixed solar panels 5° North in Currais Novos, Brazil
To maximize your solar PV system's energy output in Currais Novos, Brazil (Lat/Long -6.2106, -36.4817) throughout the year, you should tilt your panels at an angle of 5° 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 Currais Novos, 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 Currais Novos, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 5° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 10° South in Summer | 12° North in Autumn | 22° North in Winter | 0° 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.

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 Currais Novos, Brazil
The terrain surrounding Currais Novos in Rio Grande do Norte, Brazil, presents a diverse and distinctive landscape characteristic of Brazil's northeastern interior. Located in the Seridó region, Currais Novos sits within a semi-arid zone where the topography is defined by rolling hills, rocky outcrops, and shallow valleys that have been sculpted by centuries of erosion.
Topographical Features
The area is characterized by its undulating terrain with elevations generally ranging between 300 and 600 meters above sea level. The landscape exhibits a rugged beauty with numerous granite and gneiss formations that protrude from the earth, creating distinctive landmarks throughout the region. These crystalline rock formations are remnants of ancient geological processes that shaped this part of Brazil. The Seridó region where Currais Novos is situated features a combination of flat plateaus interrupted by modest mountain ranges. The Serra de Santana, a significant topographical feature in the vicinity, rises to approximately 750 meters at its highest points, creating a natural boundary and influencing local climate patterns. Vegetation in the area is predominantly caatinga, a type of desert vegetation adapted to the semi-arid conditions. This sparse, drought-resistant flora allows for excellent solar exposure throughout most of the region, with minimal natural shading from vegetation. Water bodies are relatively scarce, consisting mainly of seasonal streams that fill during the brief rainy periods and subsequently dry up. The Açude Dourado reservoir near Currais Novos represents one of the few permanent water features in the immediate vicinity.Optimal Areas for Solar PV Development
The plateaus and gently sloping areas surrounding Currais Novos offer exceptional potential for large-scale solar photovoltaic installations. Several specific zones stand out as particularly suitable: The plains extending to the east and southeast of Currais Novos present ideal conditions for solar development. These areas feature relatively flat terrain with gentle slopes of less than 5 degrees, minimizing the need for extensive grading during construction. The stable soil composition also provides good foundation conditions for mounting structures. The elevated plateaus of the Serra de Santana, approximately 15-20 kilometers to the southwest of Currais Novos, offer another promising zone. While slightly more elevated, these areas benefit from consistent exposure to sunlight throughout the day and experience minimal shading from surrounding topographical features. The northwestern corridor between Currais Novos and the neighboring municipality of Acari presents another favorable region. This area features expansive, open terrain with minimal vegetation obstruction and good accessibility via existing road networks. Areas to avoid include the more rugged, rocky outcroppings scattered throughout the region, particularly those with slopes exceeding 15 degrees. These zones would require significant site preparation, potentially increasing development costs. Similarly, the seasonal waterways and their immediate surroundings should be excluded from development plans to prevent potential flooding issues during the rainy season. The semi-arid climate of the region, with its characteristically clear skies and minimal cloud cover throughout most of the year, enhances the suitability of the entire area for solar energy harvesting. The predominantly dry conditions also reduce concerns about humidity-related efficiency losses in photovoltaic systems. In conclusion, the topography around Currais Novos presents numerous opportunities for large-scale solar PV development, with the eastern plains and southwestern plateaus offering the most favorable conditions in terms of terrain, accessibility, and natural solar exposure.Brazil solar PV Stats as a country
