Solar PV Analysis of Campinas, Brazil
Campinas, Sao Paulo, Brazil is a favorable location for solar PV generation due to its consistent sunlight throughout the year. The average daily energy production per kW of installed solar in each season is as follows: 6.72 kWh in Summer, 5.58 kWh in Autumn, 4.85 kWh in Winter, and 6.20 kWh in Spring. This tropical region experiences higher levels of solar power generation during Spring and Summer compared to Winter and Autumn.
The wet and dry seasons typical of this area do not pose significant challenges for solar power generation at this location. To optimize energy production from a fixed panel installation, it is recommended that panels be tilted at an angle of 21 degrees North.
While there are no major environmental or topographical factors impeding solar production in Campinas, Sao Paulo, it is essential to ensure proper maintenance of the panels by regularly cleaning them to remove dust or debris that may accumulate over time. This will help maintain optimal energy production levels throughout the year.
Note: The Tropics are located between 23.5° North and -23.5° South of the equator.
So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 3161 locations across Brazil. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Campinas
Seasonal solar PV output for Latitude: -22.9035, Longitude: -47.0565 (Campinas, 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 Campinas, Brazil
To maximize your solar PV system's energy output in Campinas, Brazil (Lat/Long -22.9035, -47.0565) 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 Campinas, 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 Campinas, 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 | 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 Campinas, 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 Campinas, 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 Campinas, Brazil
The topography around Campinas, Brazil is mostly flat with some rolling hills. The nearby areas that would be most suitable for large-scale solar PV are those that have a clear view of the sky and receive direct sunlight for most of the day. Areas with open fields or cleared land are ideal for large-scale solar PV installations. Additionally, areas close to roads and infrastructure can also be beneficial as they allow easy access to power lines and other necessary components.
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. These include reduced import taxes on solar equipment, accelerated depreciation of investments in renewable energy projects, and preferential financing from public banks. Additionally, some states offer additional incentives such as subsidies or grants for businesses that install solar systems.
