Solar Energy Potential in Bom Repouso, Minas Gerais, Brazil
Bom Repouso, Minas Gerais, located in Brazil at latitude -22.4496 and longitude -46.1863, presents a favorable location for solar energy generation throughout the year. This tropical location benefits from relatively consistent sunlight patterns, with seasonal variations primarily defined by wet and dry periods rather than dramatic changes in daylight duration. The solar energy production potential shows moderate seasonal fluctuation. Summer months deliver the highest energy output at 6.62kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season with 6.08kWh/day, while autumn yields 5.49kWh/day. Winter, while still productive, generates the least energy at 4.83kWh/day per kilowatt installed.Optimal Panel Installation
For maximizing year-round solar energy production in Bom Repouso, Minas Gerais, fixed solar panels should be installed at a tilt angle of 21 degrees facing North. This specific angle has been calculated to capture the optimal amount of solar radiation throughout the year, accounting for the location's position in the Southern Hemisphere and the Earth's elliptical orbit.Environmental and Weather Considerations
Several local factors may affect solar production in Bom Repouso:- Seasonal rainfall patterns, particularly during the wet season, can temporarily reduce solar output due to cloud cover and direct precipitation on panels
- Dust and pollen accumulation, common in tropical regions, may gradually decrease panel efficiency if not addressed
- Potential for occasional hailstorms in certain seasons could pose physical risks to panel integrity
Preventative Measures
To maximize energy production despite these challenges, several installation and maintenance practices are recommended:- Install panels with self-cleaning technologies or implement regular cleaning schedules, especially before and after the wet season
- Use hail-resistant panels with tempered glass if budget allows
- Consider slightly elevated installation angles (within 5° of the optimal 21° tilt) in areas prone to dust accumulation to facilitate natural cleaning during rainfall
- Implement quality surge protection and grounding systems to protect against lightning strikes during tropical storms
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Ideally tilt fixed solar panels 21° North in Bom Repouso, Brazil
To maximize your solar PV system's energy output in Bom Repouso, Brazil (Lat/Long -22.4496, -46.1863) throughout the year, you should tilt your panels at an angle of 21° 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 Bom Repouso, 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 Bom Repouso, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 21° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 7° North in Summer | 28° North in Autumn | 38° North in Winter | 16° 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 Bom Repouso, 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 Bom Repouso, 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 Bom Repouso, Brazil
Topography of Bom Repouso and Surroundings
Bom Repouso is situated in the southeastern region of Brazil, specifically in the state of Minas Gerais. The topography of this area is characterized by its mountainous landscape, as it lies within the Serra da Mantiqueira mountain range. This mountain range is part of the larger Brazilian Highlands, which dominate much of southeastern Brazil. The terrain around Bom Repouso features significant elevation changes, with altitudes typically ranging between 1,000 to 1,500 meters above sea level. The landscape consists of rolling hills, steep slopes, and numerous valleys carved by rivers and streams over geological time. This undulating terrain creates a diverse topographical profile throughout the region. The Serra da Mantiqueira provides Bom Repouso with a distinctive mountainous backdrop, with some peaks in the broader region reaching heights of over 2,000 meters. These mountains contribute to the area's microclimate and influence local weather patterns. The higher elevations experience cooler temperatures compared to the lower-lying areas, creating varied ecological zones.Hydrography and Natural Features
The region is well-watered, with numerous small rivers and streams flowing through the valleys between the hills. These waterways are part of larger river basins that eventually drain into major Brazilian river systems. The abundance of water has shaped the landscape over millennia, creating fertile valleys between the higher elevations. The natural vegetation in the region transitions between Atlantic Forest remnants and highland campo (grassland) ecosystems. Much of the original forest cover has been modified by human activities, particularly agriculture, which has adapted to the hilly terrain through terracing and contour farming in many areas.Potential Areas for Solar PV Development
When considering large-scale solar photovoltaic (PV) installations near Bom Repouso, certain topographical features become particularly important. The most suitable areas would be: Plateau regions with relatively flat terrain represent prime locations for solar PV development. These areas, which can be found interspersed among the hills, offer the advantage of easier construction and installation of solar arrays. Several such plateaus exist in the broader region surrounding Bom Repouso, particularly to the east and southeast where the terrain becomes somewhat less rugged. South-facing gentle slopes (in the Southern Hemisphere, south-facing slopes receive more consistent sunlight) present another opportunity for solar development. While northern Brazil might benefit from north-facing slopes, the southern position of Bom Repouso means that south-facing aspects often receive more direct sunlight throughout the year. These slopes, when not too steep, can be ideal for solar installations. Areas with minimal forest cover would require less clearing and environmental disruption. While much of the region has been altered by agriculture, selecting already cleared lands would minimize environmental impact and potentially reduce project costs and complications. Lower elevation areas within 20-30 kilometers of Bom Repouso, particularly those with good road access, might offer the best combination of suitable terrain and practical development considerations. These areas often feature more gradual slopes and better infrastructure connections. The valleys to the east of Bom Repouso, where the terrain begins to moderate somewhat compared to the more mountainous western approaches, present particularly promising locations. These areas maintain reasonable proximity to existing infrastructure while offering more accommodating topographical features for large-scale installations. Despite these opportunities, it should be noted that the predominantly mountainous nature of the region does present certain challenges for very large-scale solar development. Project planners would need to carefully balance topographical suitability with other factors such as grid connection possibilities, land ownership patterns, and environmental considerations.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]
Are there incentives for businesses to install solar in Brazil?
Yes, there are several incentives for businesses wanting to install solar energy in Brazil. The Brazilian government offers a range of tax credits and other financial incentives to encourage the adoption of renewable energy sources such as solar power.
