The location of Goiana, Pernambuco, Brazil, situated at latitude -7.6017 and longitude -34.9306, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant temperature fluctuations.

Seasonal Solar Performance

Solar PV systems in Goiana demonstrate robust performance across all seasons. Spring emerges as the most productive period, yielding an impressive 7.21 kWh per day for each kilowatt of installed capacity. Summer follows closely with 6.94 kWh/day, while autumn and winter maintain respectable outputs of 6.16 kWh/day and 5.58 kWh/day, respectively.

The relatively small variation between seasons indicates that Goiana is an excellent location for year-round solar energy production. Even during the least productive season (winter), the output remains substantial, ensuring a consistent energy supply throughout the year.

Optimal Panel Tilt

For fixed solar panel installations in Goiana, Pernambuco, the ideal tilt angle to maximize year-round energy production is 6 degrees North. This slight tilt 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 Goiana's climate is generally conducive to solar energy production, there are a few environmental factors to consider:

• Rainfall: The region experiences a wet season, which could temporarily reduce solar efficiency due to cloud cover.
• Humidity: High humidity levels may lead to increased dust accumulation on panels, potentially affecting their performance.

To mitigate these factors, regular cleaning and maintenance of solar panels is crucial. Additionally, installing panels with anti-reflective coatings and using microinverters or power optimizers can help maintain efficiency even during periods of partial shading or reduced sunlight.

In conclusion, Goiana, Pernambuco, Brazil, offers an ideal location for solar PV installations, with consistent and substantial energy production potential throughout the year. The minor seasonal variations and optimal panel tilt angle contribute to making this location highly suitable for solar energy projects.

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 Goiana

Seasonal solar PV output for Latitude: -7.6017, Longitude: -34.9306 (Goiana, 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 6° North in Goiana, Brazil

To maximize your solar PV system's energy output in Goiana, Brazil (Lat/Long -7.6017, -34.9306) throughout the year, you should tilt your panels at an angle of 6° 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 Goiana, 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 Goiana, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° 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	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 Goiana, 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 Goiana, Brazil.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Goiana, Brazil

The topography around Goiana, Brazil, located at latitude -7.6017 and longitude -34.9306, is characterized by a mix of coastal plains and gently rolling hills. This region, situated in the state of Pernambuco, is part of the Atlantic coastal zone of northeastern Brazil. The landscape is predominantly flat near the coast, with elevations gradually increasing as you move inland. The coastal area features sandy beaches, mangrove swamps, and estuaries where rivers meet the Atlantic Ocean. These low-lying areas are often subject to tidal influences and have rich biodiversity. As you move slightly inland, the terrain becomes more varied, with small hills and valleys interspersed throughout the landscape. The elevation rarely exceeds 100 meters above sea level in this region.

Suitable Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would be relatively flat, open areas with minimal shading from trees or other obstructions. These conditions are often found in the slightly elevated inland regions, away from the immediate coastal zone. The gently rolling hills to the west and southwest of Goiana offer promising potential for solar PV development. These areas typically have better drainage than the low-lying coastal plains, reducing the risk of flooding that could damage solar installations. Additionally, the slightly higher elevations may benefit from clearer skies and less coastal haze, potentially increasing solar energy capture. It's important to note that while the topography is generally favorable for solar PV in many areas around Goiana, other factors such as land ownership, environmental protections, and proximity to electrical infrastructure would also need to be considered when selecting specific sites for large-scale solar projects. The region's abundant sunshine and relatively stable climate make it an attractive option for solar energy development, provided these additional factors are carefully evaluated.
