Solar Energy Potential in Itaporanga, Paraíba, Brazil
Itaporanga, Paraíba, Brazil, located at latitude -7.3029 and longitude -38.2534, presents a favorable location for solar PV installations throughout the year. This tropical location benefits from consistent sunlight patterns that make it suitable for solar energy generation with minimal seasonal variation in output. The seasonal solar production data shows promising energy generation potential across all seasons. Spring stands out as the most productive period with an impressive 7.43 kWh per day for each kilowatt of installed capacity. Summer follows with 6.28 kWh/day, autumn with 6.13 kWh/day, and winter with 6.03 kWh/day. This relatively consistent output across seasons is characteristic of tropical locations where the sun's path doesn't vary as dramatically as in locations further from the equator.Optimal Panel Installation
For fixed solar panel installations in Itaporanga, Paraíba, the ideal tilt angle to maximize year-round energy production is 7 degrees facing North. This slight tilt optimizes the capture of solar radiation throughout the year, accounting for the location's proximity to the equator and the sun's position in the sky as it changes through the seasons.Environmental and Weather Considerations
Several factors could potentially impact solar production in Itaporanga:- Heavy rainfall during the wet season may reduce solar production due to cloud cover and potential panel soiling
- High temperatures typical of tropical regions can slightly reduce panel efficiency
- Dust accumulation, particularly during dry seasons, can diminish panel performance
Seasonal Optimization
While Itaporanga offers good solar potential year-round, spring clearly presents the optimal season for solar generation with nearly 20% higher daily output than winter. This makes spring an excellent time for any maintenance activities that might increase system efficiency. The relatively small variation between other seasons suggests that a fixed-tilt system is appropriate, as the added expense of tracking systems may not be justified by the modest gains they would provide.Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 7° North in Itaporanga, Brazil
To maximize your solar PV system's energy output in Itaporanga, Brazil (Lat/Long -7.3029, -38.2534) throughout the year, you should tilt your panels at an angle of 7° 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 Itaporanga, 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 Itaporanga, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 7° 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 Itaporanga, 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 Itaporanga, 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 Itaporanga, Brazil
Topographical Features of the Itaporanga Region
The landscape surrounding Itaporanga in Paraíba state, Brazil, is characterized by the distinctive topography of the Caatinga region within the Brazilian Northeast. This area sits within the Borborema Plateau, a geological formation that creates a series of rolling hills, elevated plains, and scattered rocky outcrops across the semi-arid interior. The terrain around Itaporanga features moderate elevation changes, with the town itself positioned at approximately 400 meters above sea level. The region displays typical characteristics of the agreste transition zone, where the landscape gradually shifts from the more humid coastal areas toward the drier sertão interior. Rolling hills dominate the scenery, interspersed with relatively flat valley floors and broader plateau areas. These elevated plains often extend for considerable distances, broken occasionally by seasonal watercourses and small mountain ranges that rise modestly above the surrounding terrain. Rocky outcrops and inselbergs - isolated hills that rise abruptly from the surrounding plains - punctuate the landscape throughout the region. These granite and gneiss formations create a distinctive visual character but occupy relatively small portions of the total land area. Between these features, extensive areas of gently undulating terrain provide substantial open spaces with minimal topographical obstacles.Optimal Areas for Large-Scale Solar Development
The broad plateau areas extending northeast and southwest of Itaporanga present the most favorable conditions for large-scale solar photovoltaic installations. These elevated plains offer extensive flat to gently sloping terrain that minimizes grading requirements and reduces installation costs. The consistent elevation across these areas also helps ensure uniform solar exposure without significant shading from adjacent topographical features. The valley floors between the rolling hills provide another category of suitable terrain, particularly where they broaden into wider basin areas. These locations typically feature minimal slope variations and good accessibility for construction equipment and maintenance vehicles. The relatively stable soil conditions in these valley areas, combined with their protection from strong winds, create favorable conditions for solar array foundations. Areas with southern and southeastern exposures on the gentler slopes of the rolling hills could also accommodate solar installations, though these would require more careful site planning to optimize panel orientation and minimize inter-row shading. The key advantage of these slightly elevated positions is their excellent drainage characteristics during the rainy season and reduced risk of flooding compared to lower-lying areas. The region's semi-arid climate contributes to minimal vegetation density across much of the landscape, reducing land clearing requirements for solar development. Areas that maintain distance from the seasonal watercourses and avoid the steeper rocky outcrops would provide the most straightforward development opportunities while minimizing environmental impact on the local ecosystem.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?
Yes, there are several incentives for businesses wanting to install solar energy in Brazil. The Brazilian government offers a range of tax credits and other financial incentives to encourage the adoption of renewable energy sources such as solar power.
