Solar PV Analysis of Barueri, Brazil
Barueri, São Paulo, Brazil, is a good location for generating solar energy throughout the year due to its tropical climate. The sun shines consistently here most of the year and seasons are typically marked by wet and dry periods rather than large temperature swings.
The amount of electricity that can be generated from each kilowatt (kW) of installed solar panels varies slightly with the seasons. In summer, you could expect about 6.02 kilowatt-hours (kWh) per day for each kW of installed solar panels. This drops slightly in autumn to 5.11 kWh/day, lowers further in winter to 4.21 kWh/day before rising again in spring to 5.31 kWh/day.
Therefore, while you would generate more power during summer and spring months compared to autumn and winter ones due to longer daylight hours and higher sun intensity, Barueri's consistent sunlight makes it a suitable location for solar energy production all year round.
For fixed panel installations at this location, tilting your panels at an angle of 22 degrees facing North will maximize total yearly power generation from your solar photovoltaic system since this orientation captures the most sunlight over the course of a year.
However, there might be some local factors that could affect your solar output like heavy rainfall or cloud cover during wet season which reduces sunlight exposure on your panels or even dust accumulation on panel surfaces which can reduce their efficiency over time.
To mitigate these issues:
1) You may want to install an automatic tracking system that adjusts the tilt angle of your panels throughout the day or seasonally if possible; this ensures they always face towards maximum available sunlight despite seasonal variations.
2) Regular cleaning maintenance should also be carried out especially during dry season when dust accumulation is likely high; clean panels absorb more light leading to better performance.
3) If heavy rainfall is common during certain months, considering weather-resistant equipment or protective measures may help prolong lifespan and maintain efficiency of your solar system.
Overall, with the right set-up and maintenance, Barueri offers a great potential for efficient solar energy production.
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 Barueri
Seasonal solar PV output for Latitude: -23.4977, Longitude: -46.8656 (Barueri, 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 22° North in Barueri, Brazil
To maximize your solar PV system's energy output in Barueri, Brazil (Lat/Long -23.4977, -46.8656) throughout the year, you should tilt your panels at an angle of 22° 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 Barueri, 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 Barueri, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 22° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 8° North in Summer | 29° North in Autumn | 39° North in Winter | 17° 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 Barueri, 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 Barueri, 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 Barueri, Brazil
Barueri is located in the state of São Paulo, Brazil. The topography around Barueri is relatively flat with some hilly areas. It's situated on the plateau which forms the vast majority of the southeastern region of Brazil.
The climate in this area is tropical and subtropical with a dry winter season from May to September which could be beneficial for solar power generation as there would be less cloud cover. The average annual temperature is 20°C (68°F) which is ideal for PV efficiency as solar panels tend not to perform as well under extremely high temperatures.
Large-scale solar PV installations require large tracts of land that are relatively flat and have good sun exposure throughout the year. Given these requirements, potential suitable areas near Barueri might include:
1) Agricultural lands or pastures that are not being fully utilized.
2) Rooftops of large industrial buildings or warehouses.
3) Unused land parcels within urban or suburban areas.
4) Brownfield sites, such as decommissioned industrial zones or landfills.
However, it's important to note that any decision about installing large-scale solar should also take into account other factors like local regulations, proximity to electrical grids, environmental impact assessments etc. Detailed site surveys and feasibility studies would need to be conducted before making a final decision.
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.
