The location of Ouroeste, São Paulo, Brazil, situated at latitude -19.9352 and longitude -50.4176, presents a favorable environment for solar PV energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant changes in daylight hours.

Solar energy production at this site demonstrates strong potential across all seasons. Summer months yield the highest output at 6.98 kWh per day for each kilowatt of installed solar capacity. Spring follows closely with 6.39 kWh/day, while autumn and winter show slightly lower but still substantial production at 5.83 kWh/day and 5.31 kWh/day, respectively.

Optimal Solar Generation Periods

The most ideal times for solar energy generation in Ouroeste occur during the summer months, typically from December to February. Spring (September to November) also offers excellent conditions for solar production. While autumn and winter months show a slight decrease in output, the overall yearly performance remains robust due to the location's tropical climate and relatively stable sunlight throughout the year.

For fixed panel installations at this location, the optimal tilt angle to maximize year-round solar production is 19 degrees facing North. This angle ensures the panels capture the most sunlight possible across all seasons, taking into account the Earth's elliptical orbit and the site's specific latitude.

Environmental and Weather Considerations

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

1. Rainfall: The region experiences a wet season, typically from October to March, which could temporarily reduce solar output due to cloud cover.
2. Dust and pollen: During dry periods, accumulation of dust or pollen on solar panels may slightly decrease efficiency.

To mitigate these factors, regular cleaning and maintenance of solar panels is recommended, especially during and after the wet season. Additionally, installing panels at the optimal tilt angle helps prevent water and dust accumulation. Overall, the environmental and weather conditions in Ouroeste do not pose significant obstacles to solar energy production, making it an excellent location for solar PV installations.

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 Ouroeste

Seasonal solar PV output for Latitude: -19.9352, Longitude: -50.4176 (Ouroeste, 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 Ouroeste, Brazil

To maximize your solar PV system's energy output in Ouroeste, Brazil (Lat/Long -19.9352, -50.4176) 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 Ouroeste, 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 Ouroeste, 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	36° 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.

Calculate solar panel row spacing in Ouroeste, 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 Ouroeste, 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 Ouroeste, Brazil

The topography around Ouroeste, Brazil, located at latitude -19.9352 and longitude -50.4176, is characterized by gently rolling hills and expansive plains. This region, situated in the western part of São Paulo state, is part of the larger Brazilian Plateau. The landscape is predominantly flat to slightly undulating, with occasional areas of more pronounced elevation changes. The area surrounding Ouroeste is primarily composed of agricultural land and remnants of the original Cerrado biome, a tropical savanna ecosystem. The terrain gradually slopes towards the nearby Grande River, which forms part of the border between São Paulo and Minas Gerais states. This river valley introduces some variation to the otherwise relatively uniform topography.

Suitability for Large-Scale Solar PV

Several areas near Ouroeste would be well-suited for large-scale solar photovoltaic (PV) installations. The most promising locations for such projects would be the expansive, flat agricultural lands that dominate the region. These areas offer several advantages for solar PV development: Firstly, the relatively level terrain reduces the need for extensive land preparation, making it easier and more cost-effective to install large arrays of solar panels. The absence of significant natural obstacles also minimizes shading issues, allowing for optimal solar exposure throughout the day. Secondly, the region experiences high levels of solar radiation due to its tropical location and generally clear skies. This abundance of sunlight is crucial for maximizing the efficiency and output of solar PV systems. Thirdly, the presence of existing agricultural infrastructure, including access roads and proximity to power transmission lines, could facilitate the development and grid integration of solar projects. Areas to the north and east of Ouroeste, where the terrain is particularly flat and open, would likely be the most suitable for large-scale solar PV installations. These locations offer vast tracts of land with minimal topographical constraints, ideal for accommodating extensive solar arrays. However, it's important to note that any solar PV development would need to balance energy production goals with agricultural needs and environmental considerations, particularly regarding the preservation of remaining Cerrado vegetation. Careful site selection and environmental impact assessments would be crucial to ensure sustainable development in this region.
