Cuiabá, Brazil, located at latitude -15.597 and longitude -56.0958, offers a favorable environment for solar energy production throughout the year. Situated in the tropics, this location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season cycles.

The solar energy potential in Cuiabá remains relatively stable across all seasons, with only minor fluctuations. Summer sees the highest output at 6.27 kWh per day for each kilowatt of installed solar capacity. Spring follows closely with 5.99 kWh/day, while winter and autumn produce 5.66 kWh/day and 5.56 kWh/day, respectively.

These figures indicate that Cuiabá is an excellent location for year-round solar energy generation. The difference between the highest and lowest seasonal outputs is less than 1 kWh/day, ensuring consistent energy production throughout the year. Summer and spring are particularly ideal for solar generation, but even the "lower" output seasons of autumn and winter still provide substantial energy yields.

Optimal Panel Angle

For fixed solar panel installations in Cuiabá, the ideal tilt angle to maximize year-round energy production is 15 degrees facing North. This angle optimizes the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the sun's changing position in the sky.

Environmental Considerations

While Cuiabá's climate is generally favorable for solar energy production, there are a few environmental factors to consider:

1. High temperatures: Cuiabá experiences hot weather, which can slightly reduce solar panel efficiency. Using heat-resistant panels and ensuring proper ventilation during installation can mitigate this issue.
2. Dust and pollution: The city's dry season may lead to increased dust accumulation on panels. Regular cleaning and maintenance can help maintain optimal performance.

Despite these minor challenges, Cuiabá remains an excellent location for solar energy production. With proper installation techniques and regular maintenance, solar panels in this area can consistently generate high levels of clean energy 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.

Solar output per kW of installed solar PV by season in Cuiaba

Seasonal solar PV output for Latitude: -15.597, Longitude: -56.0958 (Cuiaba, 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 15° North in Cuiaba, Brazil

To maximize your solar PV system's energy output in Cuiaba, Brazil (Lat/Long -15.597, -56.0958) throughout the year, you should tilt your panels at an angle of 15° 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 Cuiaba, 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 Cuiaba, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
0° in Summer	22° North in Autumn	31° North in Winter	10° 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 Cuiaba, 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 Cuiaba, 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 Cuiaba, Brazil

Cuiabá, the capital city of Mato Grosso state in Brazil, is situated in a region characterized by diverse topography. The city itself lies in a depression surrounded by low hills and plateaus, with an average elevation of about 165 meters above sea level. The landscape around Cuiabá is a transition zone between the Amazon rainforest to the north and the Pantanal wetlands to the south. To the east of Cuiabá, the terrain gradually rises into the Chapada dos Guimarães, a series of flat-topped plateaus and escarpments that reach heights of up to 800 meters. This area is known for its dramatic cliffs, waterfalls, and unique rock formations. The western side of the city is relatively flatter, with gently rolling hills and savanna-like vegetation typical of the Cerrado biome. The region's climate is tropical and semi-humid, with distinct wet and dry seasons. This climate, combined with the varied topography, creates a mosaic of ecosystems ranging from gallery forests along rivers to open grasslands and wooded savannas.

Suitability for Large-Scale Solar PV

When considering areas near Cuiabá for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be those with ample sunlight exposure, relatively flat terrain, and minimal environmental impact. The areas to the west and southwest of Cuiabá show the most promise for solar PV development. These regions feature expansive, gently sloping landscapes with fewer obstacles to block sunlight. The Cerrado vegetation in these areas is less dense compared to the forested regions to the north, which means less land clearing would be required for solar farm construction. Particularly promising are the areas along the BR-364 highway heading towards Rondonópolis. This corridor offers a combination of suitable topography, existing infrastructure for power transmission, and proximity to major urban centers that could benefit from the generated electricity. It's important to note that while the Chapada dos Guimarães to the east receives abundant sunlight, its rugged terrain and ecological importance make it less suitable for large-scale solar installations. Similarly, areas to the south approaching the Pantanal wetlands should be avoided due to their ecological sensitivity and potential for seasonal flooding. Any large-scale solar PV project in the region would need to carefully balance energy production goals with environmental conservation efforts, ensuring that the unique ecosystems surrounding Cuiabá are protected while harnessing the area's significant solar potential.
