Brusque, Santa Catarina, Brazil, situated in the Southern Sub Tropics, presents a moderate location for generating solar energy throughout the year. This city experiences varying levels of solar electricity production across different seasons, with notable fluctuations that impact overall efficiency.
Solar panels in Brusque generate their highest output during summer months, producing an average of 6.18kWh per day for each kilowatt of installed capacity. This production decreases to 4.46kWh/day during autumn and drops further to 3.32kWh/day in winter, which represents the yearly low point. Spring brings improved conditions with production rising to 4.73kWh/day.
Seasonal Variations and Optimization
The significant difference between summer and winter production (nearly 50% reduction) indicates that Brusque experiences substantial seasonal variability. This pattern is typical for locations in the Southern Sub Tropics, where winter months receive less solar radiation due to shorter days and lower sun angles.
For fixed solar panel installations in Brusque, Santa Catarina, the ideal tilt angle to maximize year-round energy production is 24 degrees facing North. This specific angle has been calculated to optimize the annual solar harvest, taking into account the location's latitude and seasonal sun paths.
Environmental Considerations
Several environmental factors could potentially impact solar production in Brusque. The region experiences a humid subtropical climate with rainfall distributed throughout the year, which can reduce solar efficiency through cloud cover. Additionally, the area may be subject to occasional fog and mist, particularly in valley locations.
To mitigate these challenges, several preventative measures can be implemented:
- Installing panels with anti-reflective coatings that perform better in diffuse light conditions common during cloudy periods
- Implementing robust mounting systems that can withstand occasional strong winds
- Using micro-inverters or power optimizers to minimize the impact of partial shading
- Scheduling more frequent cleaning routines to address potential dust and pollen accumulation, which is common in subtropical regions
While Brusque may not offer the exceptional solar conditions found in desert regions, its year-round production remains viable for solar PV installations, particularly when properly optimized with the correct tilt angle and appropriate equipment selections.
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.

Solar output per kW of installed solar PV by season in Brusque
Seasonal solar PV output for Latitude: -27.1147, Longitude: -48.8997 (Brusque, 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 24° North in Brusque, Brazil
To maximize your solar PV system's energy output in Brusque, Brazil (Lat/Long -27.1147, -48.8997) throughout the year, you should tilt your panels at an angle of 24° 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 Brusque, 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 Brusque, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 24° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° North in Summer | 33° North in Autumn | 43° North in Winter | 20° 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 Brusque, 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 Brusque, 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 Brusque, Brazil
Topography of Brusque, Brazil
Brusque is situated in the state of Santa Catarina in southern Brazil, nestled within a valley of the Itajaí-Mirim River. The topography surrounding Brusque is characterized by a diverse landscape that combines rolling hills, steep slopes, and narrow valleys. The region is part of the Atlantic Plateau, which extends along much of Brazil's southeastern and southern coastline. The terrain around Brusque features significant elevation changes, with hills rising to several hundred meters above sea level. These hills are part of the Serra do Mar mountain range, which runs parallel to the Atlantic coast. The landscape is deeply cut by river valleys, creating a corrugated pattern of ridges and depressions throughout the region. The city itself lies at approximately 21 meters above sea level, but the surrounding hills quickly rise to much higher elevations. This varied topography creates numerous microclimates within relatively short distances. The Itajaí-Mirim River, which flows through Brusque, has shaped the valley floor through centuries of erosion, creating flatter areas along its banks. Dense Atlantic Forest vegetation historically covered these hills, though much has been cleared for agricultural and urban development. The remaining forested areas tend to be concentrated on steeper slopes where development is more challenging.Suitable Areas for Solar PV Development
When considering large-scale solar photovoltaic (PV) development near Brusque, several topographical factors must be taken into account. The ideal areas would combine favorable terrain conditions with good solar exposure. The higher elevation plateaus and gentler slopes to the west and northwest of Brusque present some of the most promising terrain for large-scale solar installations. These areas typically feature more consistent topography with fewer steep gradients, making construction and maintenance more feasible. The elevated position also reduces the risk of shadowing from surrounding hills. Areas with southern exposure (facing north in the Southern Hemisphere) would be particularly advantageous for solar collection. The northern-facing slopes of hills around Brusque would receive more direct sunlight throughout the year compared to south-facing slopes, which may experience significant shadowing during winter months. The relatively flat agricultural lands along the broader sections of the Itajaí-Mirim River valley could also be suitable for solar development, particularly in areas that are not prone to flooding. These locations offer easier access for construction and maintenance vehicles and typically require less site preparation than hillier terrain. It's worth noting that the coastal plains farther east of Brusque, where the topography flattens considerably as it approaches the Atlantic Ocean, may also offer suitable conditions for large-scale solar installations. These areas generally have fewer topographical barriers, though they must be balanced against other land use considerations. Areas to avoid would include the steepest hillsides, densely forested regions, and flood-prone sections of river valleys. The deeply incised valleys with limited sky view factors would also be suboptimal due to reduced direct sunlight exposure and potential shadowing from surrounding terrain. The complex topography around Brusque means that site-specific assessments would be essential for any large-scale solar development, as local conditions can vary significantly over short distances due to the region's varied terrain.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.
