Novo Mundo, Mato Grosso, Brazil presents an excellent location for year-round solar energy generation, with its tropical positioning delivering consistently strong solar output throughout all seasons.

Solar Energy Performance

The solar energy data for this location shows impressive and reliable performance across all seasons. Winter emerges as the peak production period, generating 6.12 kWh per day for each kilowatt of installed solar capacity. Spring follows closely with 5.69 kWh/day, while autumn produces 5.21 kWh/day. Even summer, the lowest-producing season, still delivers a robust 4.91 kWh/day per kW installed. This seasonal pattern is typical for locations in the Southern Hemisphere tropics, where winter months often provide clearer skies and optimal sun angles. The relatively small variation between seasons - only about 1.2 kWh difference between the highest and lowest months - demonstrates the location's reliability for consistent solar energy production. For fixed panel installations at this location, the ideal tilt angle is 11 degrees facing North. This angle maximizes total year-round solar production by optimizing the panels' exposure to the sun's path throughout the year.

Environmental and Weather Challenges

Several factors in this tropical location could potentially impact solar energy production:

• Heavy rainfall during wet season: Tropical regions experience intense rainfall periods that can reduce solar irradiance and create soiling issues on panels
• High humidity levels: Persistent moisture can lead to corrosion of electrical components and reduced system efficiency
• Dust and vegetation growth: The combination of dry periods followed by wet seasons can create significant dust accumulation and rapid vegetation growth around installations
• Extreme temperatures: High ambient temperatures can reduce panel efficiency and stress electrical components

Preventative Measures for Optimal Performance

To maximize solar energy production despite these challenges, several installation strategies should be implemented:

• Enhanced drainage systems: Install proper drainage around ground-mounted systems and ensure roof-mounted systems have adequate water runoff
• Regular cleaning schedules: Establish frequent panel cleaning routines, particularly before and after wet seasons
• Corrosion-resistant materials: Use marine-grade or tropical-rated electrical components, mounting hardware, and wiring designed for high-humidity environments
• Vegetation management: Maintain clear zones around installations and implement regular landscaping to prevent shading
• Adequate ventilation: Ensure proper air circulation behind panels to reduce operating temperatures and improve efficiency

Despite these considerations, Novo Mundo's consistent high solar output throughout the year makes it an ideal location for solar energy projects. With proper installation techniques and maintenance practices, solar installations can achieve excellent performance and reliability in this tropical environment.

Solar output per kW of installed solar PV by season in Novo Mundo

Seasonal solar PV output for Latitude: -9.8366, Longitude: -55.3135 (Novo Mundo, 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 11° North in Novo Mundo, Brazil

To maximize your solar PV system's energy output in Novo Mundo, Brazil (Lat/Long -9.8366, -55.3135) throughout the year, you should tilt your panels at an angle of 11° 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 Novo Mundo, 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 Novo Mundo, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 11° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
6° South in Summer	17° North in Autumn	26° North in Winter	4° 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 Novo Mundo, 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 Novo Mundo, 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 Novo Mundo, Brazil

Topographical Features of Novo Mundo Region

Novo Mundo is situated in the northern region of Mato Grosso state, Brazil, positioned at the transition zone between the Amazon rainforest and the Cerrado savanna. The landscape around this municipality is characterized by relatively flat to gently rolling terrain, with elevations typically ranging from 200 to 400 meters above sea level. This area sits on the southern edge of the Amazon Basin, where the topography gradually rises from the lowland rainforest areas to the north toward the higher plateau regions of the Cerrado to the south. The terrain features expansive plains interspersed with low hills and occasional escarpments. Much of the original forest cover has been cleared for agricultural purposes, particularly cattle ranching and soybean cultivation, creating vast open areas with minimal tree coverage. The region experiences a well-defined wet and dry season pattern, with the dry season typically extending from May through September.

Drainage and Water Features

The area is drained by numerous small rivers and streams that flow northward toward the Amazon River system. The Teles Pires River, a major tributary of the Tapajós River, flows through the broader region. During the wet season, some lower-lying areas may experience seasonal flooding, while the dry season reveals extensive flat areas that remain well-drained throughout the year.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations would be the extensive flat to gently sloping areas that have already been cleared for agriculture. These areas offer several advantages including minimal grading requirements, existing access infrastructure, and reduced environmental impact since the land has already been modified from its natural state. The elevated plateau areas to the south and southeast of Novo Mundo present particularly attractive conditions for solar development. These locations benefit from consistent terrain grades of less than five percent, excellent drainage characteristics that prevent water accumulation, and strong road networks established for agricultural transport. The cleared pasturelands and areas transitioning out of agricultural use would be ideal candidates, as they provide large contiguous parcels without the need for extensive forest clearing. Areas closer to existing electrical transmission infrastructure would be preferable, as the region has developed power lines to support agricultural operations and rural communities. The flatter sections of former soybean fields offer especially good potential, as they already possess the level terrain and clear sight lines that optimize solar panel placement and maintenance access.
