Solar Energy Potential in Timon, Maranhão, Brazil
Timon, Maranhão, Brazil, located at coordinates -5.2006, -42.8783, offers excellent conditions for solar energy generation throughout the year. This tropical location benefits from consistent sunlight patterns that make it highly suitable for photovoltaic (PV) systems. The solar energy production potential in Timon shows impressive output across all seasons. During summer, each kilowatt of installed solar capacity can generate approximately 5.59 kWh per day. This production increases to 6.14 kWh/day in autumn, and reaches its peak during winter with 6.63 kWh/day. Spring maintains this high performance with a slightly higher 6.66 kWh/day output. Interestingly, winter and spring represent the most productive seasons for solar generation in Timon, Maranhão, contrary to what might be expected in non-tropical regions. This pattern reflects the local climate dynamics, where the dry season often coincides with clearer skies that enhance solar radiation reaching the panels.Optimal Panel Installation
For fixed solar panel installations in Timon, Maranhão, the ideal tilt angle to maximize year-round energy production is 6 degrees facing North. This relatively flat orientation reflects Timon's proximity to the equator, where the sun passes nearly overhead throughout much of the year.Environmental and Weather Considerations
Several environmental factors could potentially impact solar production in Timon:- Heavy rainfall during the wet season can temporarily reduce solar output due to cloud cover and direct precipitation on panels
- Dust accumulation is common in tropical regions with distinct dry seasons, which can gradually decrease panel efficiency
- High humidity levels may contribute to accelerated degradation of electrical components if not properly protected
Recommended Preventative Measures
Installing panels with self-cleaning technologies or implementing regular cleaning schedules can address dust accumulation issues, especially important before and during the dry season. Using corrosion-resistant components and proper sealing of electrical connections will help protect against humidity-related degradation. Additionally, incorporating slightly elevated tilt angles beyond the mathematical optimum might be beneficial for natural cleaning during rainstorms, though this should be balanced against the minor reduction in annual production. The consistent year-round production profile makes Timon an excellent location for solar PV systems that can provide reliable renewable energy with minimal seasonal fluctuations, making energy planning more predictable compared to locations with more variable seasonal outputs.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 Timon
Seasonal solar PV output for Latitude: -5.2006, Longitude: -42.8783 (Timon, 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 6° North in Timon, Brazil
To maximize your solar PV system's energy output in Timon, Brazil (Lat/Long -5.2006, -42.8783) throughout the year, you should tilt your panels at an angle of 6° 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 Timon, 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 Timon, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 6° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 11° South in Summer | 12° North in Autumn | 21° North in Winter | 0° 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 Timon, 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 Timon, 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 Timon, Brazil
The topography surrounding Timon, Brazil presents a varied landscape characterized by gentle undulations and modest elevations. Situated in the northeastern state of Maranhão, Timon rests on the western bank of the Parnaíba River, which forms a natural boundary with the neighboring state of Piauí. The terrain generally consists of low-lying plains with occasional rolling hills, typically ranging from 100 to 200 meters above sea level. The region exhibits characteristics of a transition zone between the Amazon rainforest and the semi-arid northeastern Brazilian interior. The landscape features a mix of cerrado (tropical savanna) vegetation, with scattered trees and shrubby undergrowth that becomes sparser as one moves eastward toward more arid conditions. The Parnaíba River valley introduces riparian elements to the topography, with slightly more lush vegetation along its banks compared to areas further inland.
Soil and Surface Features
The soils around Timon tend to be predominantly sandy and lateritic, with moderate to poor fertility. These soils have developed under tropical conditions with seasonal rainfall patterns, resulting in considerable leaching of nutrients. The surface features include occasional rocky outcrops, particularly in areas of higher elevation, while the lower plains may experience seasonal flooding during the rainy period. Erosion patterns are visible throughout the landscape, with shallow gullies and drainage channels cutting through the terrain, particularly on sloped areas. These features become more pronounced during the rainy season when water runoff carves temporary waterways across the landscape.Solar PV Potential Areas
For large-scale solar photovoltaic installations, several areas near Timon offer favorable conditions. The most suitable locations would be the elevated plateaus and gently sloping terrain to the south and southwest of the city. These areas benefit from minimal shading due to their elevation and relatively flat expanses, allowing for optimal solar exposure throughout the day. The drier regions extending eastward from Timon also present excellent opportunities for solar development. These areas feature less vegetation coverage and more consistent sun exposure due to reduced cloud cover compared to areas closer to the Amazon basin. The naturally sparse vegetation in these zones would require minimal clearing for installation, reducing environmental impact and preparation costs. Areas to avoid would include the immediate vicinity of the Parnaíba River and its tributaries, which may be subject to seasonal flooding and typically support denser vegetation that would require significant clearing. Additionally, the few steeper hillsides in the region would present installation challenges and potential erosion concerns during construction and operation. The relatively stable ground conditions across much of the region, with bedrock not far below the surface in many locations, provides good foundation options for solar array mounting systems. The predominantly sandy soils also offer reasonable drainage characteristics, reducing concerns about waterlogging during seasonal rains.Accessibility Considerations
The topography around Timon generally permits good accessibility for construction and maintenance of solar facilities. The moderate terrain allows for the development of access roads without requiring extensive earthworks. The existing road network, particularly along the BR-316 highway corridor, provides potential connection points for new solar developments to transportation infrastructure. The open, gently rolling landscape also facilitates the efficient layout of solar arrays, allowing for optimal spacing and orientation to maximize energy capture while minimizing land use. These topographical advantages, combined with the region's climate characteristics, make the areas surrounding Timon particularly well-suited for large-scale solar energy development.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.
