Louveira, São Paulo, Brazil, situated in the tropical region, offers a promising location for solar energy generation throughout the year. The city's geographical position provides relatively consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant temperature fluctuations.
Seasonal Solar Performance
Solar panel performance in Louveira varies across the meteorological seasons:
- Summer: 6.05 kWh/day
- Autumn: 5.07 kWh/day
- Winter: 4.15 kWh/day
- Spring: 5.32 kWh/day
Optimal Generation Periods
The most productive periods for solar energy generation in Louveira are during the summer months, typically from December to February. Spring and autumn also offer favorable conditions, while winter experiences a slight dip in output. However, the relatively small variation between seasons indicates that solar PV systems can operate efficiently year-round in this location.
Panel Installation Angle
For fixed panel installations in Louveira, São Paulo, the ideal tilt angle to maximize year-round solar production is 21 degrees facing North. This angle optimizes the panels' exposure to sunlight throughout the year, taking into account the city's latitude and the Earth's elliptical orbit.
Environmental Considerations
While Louveira's tropical climate is generally favorable for solar energy production, there are a few factors to consider: 1. Rainfall: The region experiences a wet season, which could temporarily reduce solar output. Installing panels at the optimal angle helps water runoff and prevents accumulation. 2. Dust and pollution: Urban areas may experience higher levels of airborne particles. Regular cleaning and maintenance of solar panels can mitigate this issue. 3. Cloud cover: Occasional cloud cover during the wet season may impact solar generation. Using high-efficiency panels and proper sizing of the system can help offset these temporary reductions in output.
Overall, Louveira presents a highly suitable location for solar PV installations, with consistent year-round production potential and manageable environmental factors.
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 Louveira
Seasonal solar PV output for Latitude: -23.0815, Longitude: -46.9351 (Louveira, 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 21° North in Louveira, Brazil
To maximize your solar PV system's energy output in Louveira, Brazil (Lat/Long -23.0815, -46.9351) 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 Louveira, 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 Louveira, 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 | 29° North in Autumn | 39° 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 Louveira, 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 Louveira, 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 Louveira, Brazil
The topography around Louveira, Brazil, is characterized by a mix of gently rolling hills and small valleys, typical of the southeastern region of São Paulo state. The area is part of the Atlantic Plateau, which features undulating terrain with elevations ranging from approximately 600 to 800 meters above sea level. The landscape is dotted with patches of remnant Atlantic Forest vegetation interspersed with agricultural lands and urban development. Louveira itself is situated in a relatively flat area, but the surrounding region becomes more hilly as you move outward. To the east and northeast, the terrain gradually rises towards the Serra da Mantiqueira mountain range, while to the west and southwest, it slopes gently towards the Tietê River basin. The area is crisscrossed by small streams and rivers, which have carved shallow valleys over time.
Solar PV Potential
When considering areas nearby that would be most suited for large-scale solar PV installations, several factors come into play. The ideal locations would have the following characteristics: Firstly, relatively flat or gently sloping land would be preferable, as it reduces the cost and complexity of installation. Areas to the south and southwest of Louveira, where the terrain becomes less hilly, could be suitable candidates. Secondly, regions with minimal forest cover and current agricultural use might be more easily repurposed for solar farms. The rural areas surrounding Louveira, particularly those already used for crop cultivation or pasture, could be potential sites. Thirdly, proximity to existing electrical infrastructure is important for connecting to the grid. Areas near major roads or power lines would be advantageous. The region between Louveira and Vinhedo, or the outskirts of Jundiaí to the east, might offer good connectivity options. Lastly, locations with high sun exposure and minimal shading from nearby hills or mountains would be ideal. The more open, less forested areas to the west and northwest of Louveira could provide better solar insolation. It's worth noting that while the topography around Louveira is generally favorable for solar PV, any large-scale installation would require detailed site-specific assessments, including environmental impact studies and local zoning considerations. The region's proximity to urban areas and its agricultural importance may also influence the feasibility and desirability of large solar farms in certain locations.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.
