Lagoa da Prata, Brazil, situated in the tropical region, offers a favorable environment for solar energy generation throughout the year. This location benefits from consistent sunlight and experiences seasons primarily characterized by wet and dry periods rather than significant temperature variations.
Seasonal Solar Performance
The solar energy output at this location demonstrates a relatively steady performance across all seasons, with some variations:
- Summer: 6.47 kWh/day
- Autumn: 5.86 kWh/day
- Winter: 5.28 kWh/day
- Spring: 6.10 kWh/day
Optimal Generation Periods
The data indicates that summer and spring are the most productive seasons for solar energy generation in Lagoa da Prata. However, the relatively small difference between the highest and lowest seasonal outputs suggests that this location is suitable for year-round solar energy production. The consistency in sunlight availability throughout the year is a significant advantage for solar PV systems in this area.
Panel Tilt Angle
For fixed solar panel installations in Lagoa da Prata, the ideal tilt angle to maximize year-round energy production is 19 degrees facing North. This angle has been calculated taking into account the location's latitude, daily solar elevation angles, and weighted by the daily photovoltaic potential using NASA's solar irradiance data.
Environmental Considerations
While Lagoa da Prata generally presents favorable conditions for solar energy production, there are a few environmental factors to consider: 1. Rainfall: The region experiences a wet season, which could potentially reduce solar efficiency due to cloud cover. Installing panels with good water-shedding capabilities and ensuring proper drainage can mitigate this issue. 2. Dust and pollen: Being in a tropical area, dust and pollen accumulation on panels could slightly reduce efficiency. Regular cleaning and maintenance of the panels can help maintain optimal performance. 3. Temperature: High temperatures in tropical regions can slightly decrease solar panel efficiency. Choosing panels with good heat tolerance and ensuring adequate ventilation during installation can help address this concern.
Overall, Lagoa da Prata presents an ideal location for solar PV installations, with consistent year-round production potential and manageable environmental challenges.
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 Lagoa Da Prata
Seasonal solar PV output for Latitude: -20.0006, Longitude: -45.4964 (Lagoa Da Prata, 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 19° North in Lagoa Da Prata, Brazil
To maximize your solar PV system's energy output in Lagoa Da Prata, Brazil (Lat/Long -20.0006, -45.4964) throughout the year, you should tilt your panels at an angle of 19° 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 Lagoa Da Prata, 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 Lagoa Da Prata, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 4° North in Summer | 26° North in Autumn | 35° North in Winter | 14° 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.

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 Lagoa Da Prata, 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 Lagoa Da Prata, Brazil
The topography around Lagoa da Prata, Brazil, is characterized by gently rolling hills and expansive plains typical of the Cerrado biome. This region, located in the state of Minas Gerais, features a mix of grasslands, savannas, and scattered woodlands. The terrain is generally flat to moderately undulating, with occasional areas of more pronounced elevation changes. The city of Lagoa da Prata itself sits at an elevation of approximately 650 meters above sea level. The surrounding landscape gradually rises and falls, creating a patchwork of low hills and shallow valleys. Rivers and streams meander through the area, including the São Francisco River, which flows to the west of the city.
Suitable Areas for Large-Scale Solar PV
The regions surrounding Lagoa da Prata offer several promising locations for large-scale solar photovoltaic (PV) installations. The most suitable areas would be the open, flat expanses of land to the east and southeast of the city. These areas benefit from minimal shading due to their relatively level terrain and sparse vegetation. The gently sloping hillsides to the north and northeast of Lagoa da Prata also present favorable conditions for solar PV development. These locations receive ample sunlight throughout the year and have sufficient space for extensive arrays of solar panels. It's worth noting that the Cerrado region experiences a tropical savanna climate with distinct wet and dry seasons. This climate pattern, combined with the area's latitude, results in high levels of solar radiation, making it particularly attractive for solar energy production. When considering specific sites for solar PV installations, factors such as proximity to existing power infrastructure, road access, and environmental impact would need to be carefully evaluated. Additionally, areas near water bodies or in low-lying regions prone to flooding should be avoided to ensure the longevity and efficiency of the solar installations. Overall, the topography and climate of the region surrounding Lagoa da Prata provide numerous opportunities for the development of large-scale solar PV projects, potentially contributing to Brazil's growing renewable energy sector.Brazil solar PV Stats as a country
