Trindade, Goiás, Brazil, located at latitude -16.6513 and longitude -49.5671, offers a very favorable environment for solar PV installations throughout the year. Situated in the tropics, this location benefits from consistent sunlight patterns that make it an attractive spot for solar energy generation.
Seasonal Solar Production
The solar energy potential at this location remains remarkably stable across all seasons, with only minor fluctuations throughout the year. In spring, panels produce their highest output at 6.37 kWh per day for each kilowatt installed. Summer follows closely with 6.29 kWh/day, while autumn and winter show slightly lower but still robust production at 5.92 kWh/day and 5.88 kWh/day respectively.
This consistent performance across seasons is a significant advantage compared to locations at higher latitudes where winter production often drops dramatically. The minimal seasonal variation makes Trindade an excellent location for year-round solar energy reliance.
Optimal Panel Installation
For fixed solar panel installations in Trindade, Goiás, the ideal tilt angle to maximize year-round energy production is 16 degrees facing North. This specific angle has been calculated to capture the optimal amount of sunlight throughout the year, accounting for the Earth's elliptical orbit and the site's tropical location.
Environmental and Weather Considerations
Despite the excellent solar potential, there are some environmental factors to consider when installing solar PV systems in Trindade:
- The region experiences distinct wet and dry seasons, with heavy rainfall during the wet season potentially reducing solar efficiency due to cloud cover.
- High humidity levels can cause accelerated degradation of equipment if not properly protected.
- Dust accumulation during the dry season can gradually reduce panel efficiency.
Preventative Measures
To maximize solar production despite these challenges, several preventative measures are recommended:
- Install panels with high-quality waterproof sealing and anti-corrosion treatments to withstand the humid tropical environment.
- Implement a regular cleaning schedule, especially during the dry season when dust accumulation is highest.
- Consider slightly oversizing the system to account for the minor production decreases during the rainier periods.
- Use micro-inverters or power optimizers to minimize the impact of partial shading from occasional cloud cover.
Overall, Trindade presents an excellent location for solar PV installations with its consistent year-round production. With proper installation at the recommended 16-degree northward tilt and appropriate maintenance measures, solar systems in this location can provide reliable renewable energy with minimal seasonal fluctuations.

Ideally tilt fixed solar panels 16° North in Trindade, Brazil
To maximize your solar PV system's energy output in Trindade, Brazil (Lat/Long -16.6513, -49.5671) throughout the year, you should tilt your panels at an angle of 16° 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 Trindade, 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 Trindade, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° North in Summer | 23° North in Autumn | 32° North in Winter | 11° 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 Trindade, 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 Trindade, 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 Trindade, Brazil
The topography surrounding Trindade, Brazil is characterized by gently rolling hills and plateaus typical of the central Brazilian highlands. Situated in the state of Goiás, approximately 20 kilometers from the state capital Goiânia, Trindade sits at an elevation of about 750 meters above sea level. The landscape features a mix of open grasslands (known locally as "cerrado") interspersed with patches of woodland and gallery forests along water courses. The terrain gradually slopes down from northwest to southeast, with modest elevation changes throughout the region. Several small rivers and streams cut through the landscape, creating shallow valleys. The soil composition is predominantly lateritic, with reddish clay-like characteristics typical of tropical regions that have experienced significant weathering over geological time.
Seasonal Landscape Changes
The region experiences distinct wet and dry seasons which significantly impact the appearance of the landscape. During the rainy season (October to April), the vegetation becomes lush and green, while the dry season (May to September) transforms the landscape to golden-brown tones as grasses dry out. This seasonal pattern affects both natural drainage and ground stability throughout the year.Optimal Areas for Solar PV Development
The most suitable areas for large-scale solar photovoltaic development near Trindade would be the gently sloping plains to the east and southeast of the municipality. These areas offer several advantages: First, they feature relatively flat terrain with slopes generally less than 5 degrees, minimizing the need for extensive grading and reducing construction costs. The southeastern plains, extending toward Aparecida de Goiânia, present particularly favorable topographic conditions with expansive open areas. Second, these regions have minimal forest cover and are predominantly covered by cerrado vegetation or are already converted to agricultural use, reducing environmental impact and simplifying land clearance requirements. Third, the elevation of these plateaus (ranging from 700-800 meters) provides good exposure to sunlight throughout the day with minimal shadowing from topographic features. The natural drainage patterns in these areas also reduce the risk of flooding, which is beneficial for infrastructure longevity. The northwestern sectors, while still suitable, present slightly more undulating terrain that might require additional site preparation. Areas directly adjacent to water courses should be avoided due to environmental protection regulations and potential seasonal flooding concerns. Access to existing transmission infrastructure is also favorable in the eastern corridor between Trindade and Goiânia, where the regional power grid is more developed, potentially reducing interconnection costs for new solar facilities.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]
