Catende, Pernambuco, Brazil, situated at latitude -8.6634 and longitude -35.7533, offers a promising location for solar energy generation throughout the year. This tropical setting benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant temperature fluctuations.
Solar Energy Potential
The solar energy output in Catende demonstrates a favorable pattern across all seasons. Spring emerges as the most productive period, with an impressive 6.77 kWh per day for each kilowatt of installed solar capacity. Summer follows closely, yielding 6.29 kWh/day, while autumn and winter show slightly reduced but still substantial outputs of 5.38 kWh/day and 4.73 kWh/day, respectively. This data indicates that Catende maintains a strong solar energy potential year-round, with only minor fluctuations between seasons. The consistent sunlight typical of tropical regions contributes to this stability, making it an ideal location for solar PV installations.Optimal Panel Positioning
For fixed solar panel installations in Catende, Pernambuco, the ideal tilt angle to maximize year-round energy production is 7 degrees North. This slight inclination helps optimize the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's proximity to the equator.Environmental Considerations
While Catende's tropical climate is generally favorable for solar energy production, there are a few environmental factors to consider: 1. High humidity: The region's tropical climate can lead to increased humidity, potentially affecting solar panel efficiency. 2. Heavy rainfall: Wet seasons may bring periods of reduced sunlight due to cloud cover and precipitation. To mitigate these factors, several preventative measures can be implemented: - Use corrosion-resistant materials for mounting systems and electrical components to withstand high humidity. - Install panels at the recommended 7-degree tilt to facilitate natural cleaning during rainfall and prevent water accumulation. - Implement a regular cleaning schedule to remove any dust or debris that may accumulate during dry periods. - Consider using bifacial solar panels to capture reflected light, potentially increasing energy production during overcast conditions. By addressing these environmental factors and implementing appropriate preventative measures, solar installations in Catende can maximize their energy production potential, taking full advantage of the location's favorable solar conditions throughout the year.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 Catende, Brazil
To maximize your solar PV system's energy output in Catende, Brazil (Lat/Long -8.6634, -35.7533) 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 Catende, 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 Catende, 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 |
|---|---|---|---|
| 7° South in Summer | 14° North in Autumn | 24° 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 Catende, 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 Catende, 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 Catende, Brazil
The topography around Catende, Brazil, is characterized by a diverse landscape featuring rolling hills, shallow valleys, and scattered plateaus. This region, located in the state of Pernambuco, is part of the coastal Atlantic Forest biome, which transitions into a drier interior as you move westward. The terrain is generally undulating, with elevations ranging from about 150 to 400 meters above sea level. The area surrounding Catende is predominantly rural, with a mix of agricultural lands and remnants of the original Atlantic Forest. Small rivers and streams crisscross the landscape, creating a network of waterways that have shaped the local topography over time. The gentle slopes and open areas interspersed with patches of forest create a patchwork effect when viewed from above.
Potential for Solar PV Development
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The ideal locations would be relatively flat or gently sloping terrain with good exposure to sunlight throughout the day. Areas to the west and southwest of Catende might be particularly promising for solar development. These regions tend to have slightly higher elevations and less forest cover, which could provide more open spaces for solar arrays. The gradual transition to a drier climate as you move inland also means potentially clearer skies and more consistent sunlight exposure. Additionally, existing agricultural lands that are less productive could be repurposed for solar farms, offering a dual benefit of clean energy production and economic diversification for the region. It's important to note that any large-scale solar PV project would need to carefully consider environmental impacts, particularly given the ecological importance of the Atlantic Forest biome. Ideal sites would balance the need for open, sun-exposed areas with the preservation of critical habitats and water resources. Areas that have already been cleared for agriculture or other human activities might offer the best compromise between development and conservation goals.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]
