Solar PV Analysis of Toledo, Brazil
Situated in the Southern Sub Tropics, Toledo, Parana, Brazil (latitude: -24.7337, longitude: -53.8202) presents an optimal setting for solar photovoltaic (PV) power generation. The city's climatic conditions and geographic location contribute to its suitability for solar energy production throughout the year.
In summer, when sunlight is most abundant and temperatures are at their peak, one can anticipate generating approximately 7.11kWh per day for each kW of installed solar capacity. As we transition into autumn, the daily average yield reduces slightly to around 5.46kWh per kW due to shorter daylight hours and cooler weather conditions.
Winter sees a further decrease in energy yield with an average of 4.12kWh per day per kW due to fewer hours of sunlight and lower sun angles; however this is still a viable output considering winter conditions. As spring arrives with longer daylight hours and warmer temperatures again increasing the efficiency of the panels, we see an increase in output back up to about 6.08kWh/day per kW.
For fixed panel installations at this location it is ideal if panels are tilted at an angle of approximately 22 degrees facing North which maximizes exposure to sunlight throughout the year leading to more efficient energy production.
However it's important also consider potential environmental challenges that could affect solar power generation in Toledo such as heavy rain or hail storms which may cause physical damage or dirt accumulation on panels reducing their efficiency until cleaned or repaired as necessary.
To mitigate these risks during installation process it would be prudent to install protective measures like sturdy mounting structures resistant against extreme weather events and regular maintenance plans for cleaning panels ensuring optimal performance over time.
This way despite occasional setbacks from weather events Toledo remains a highly suitable location for harnessing solar energy effectively year-round.
Note: The Southern Sub Tropics extend from -23.5° latitude South down to -35° latitude.
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 Toledo
Seasonal solar PV output for Latitude: -24.7337, Longitude: -53.8202 (Toledo, 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 Toledo, Brazil
To maximize your solar PV system's energy output in Toledo, Brazil (Lat/Long -24.7337, -53.8202) 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 Toledo, 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 Toledo, 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 |
|---|---|---|---|
| 9° North in Summer | 30° North in Autumn | 40° 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 Toledo, 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 Toledo, 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 Toledo, Brazil
The topography around Toledo, Brazil is generally flat with some rolling hills. The area around the city is mostly grassland and agricultural fields. The nearby areas that would be most suited for large-scale solar PV are the flat open spaces on the outskirts of the city, such as along highways or in agricultural fields away from residential areas. These areas would provide ample space for large solar arrays and have plenty of unobstructed sunlight exposure throughout the year.
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.
