Solar Energy Potential in Cidade Ocidental, Goiás, Brazil

Cidade Ocidental, Goiás, Brazil offers an excellent location for solar energy production, with consistently high electricity generation potential throughout the year. This tropical location maintains relatively stable solar energy production across all seasons, making it highly suitable for photovoltaic (PV) installations. The seasonal solar electricity production shows remarkable consistency. During summer months, solar panels generate approximately 6.32kWh per day for each kilowatt of installed capacity. This production dips only slightly to 5.92kWh/day in autumn and 5.89kWh/day in winter. By spring, production rebounds to 6.25kWh/day per installed kilowatt.

Optimal Panel Positioning

For fixed solar panel installations in Cidade Ocidental, Goiás, the ideal tilt angle to maximize year-round electricity production is 16 degrees facing North. This specific angle has been calculated to optimize solar capture throughout the year, accounting for the Earth's elliptical orbit and the location's position in the Southern Hemisphere.

Environmental Considerations

Despite the excellent solar potential, several environmental factors should be considered when installing solar systems in Cidade Ocidental:

• Seasonal rainfall: The region experiences distinct wet and dry seasons typical of tropical climates. Heavy rainfall during the wet season may temporarily reduce solar efficiency and requires proper drainage systems around panel installations.
• Dust accumulation: During dry periods, dust can build up on panels, potentially reducing efficiency by 5-15%. Regular cleaning schedules or automated cleaning systems are recommended.
• High temperatures: While sunlight is abundant, excessive heat can actually reduce panel efficiency. Installing panels with sufficient airflow beneath them and using temperature-resistant models can mitigate this effect.

Maximizing Solar Production

To achieve optimal performance in Cidade Ocidental, Goiás, solar installations should incorporate elevated mounting systems with proper ventilation to reduce heat-related efficiency losses. Additionally, implementing semi-annual maintenance schedules aligned with the transition between wet and dry seasons will help ensure panels remain clean and fully operational. The minimal seasonal variation in production makes this location ideal for consistent, year-round solar energy generation without the significant winter production drops seen in locations farther from the equator. With proper installation and maintenance practices, solar energy systems in Cidade Ocidental can provide reliable renewable energy throughout the entire year.

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 Cidade Ocidental

Seasonal solar PV output for Latitude: -16.0772, Longitude: -47.9264 (Cidade Ocidental, 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 16° North in Cidade Ocidental, Brazil

To maximize your solar PV system's energy output in Cidade Ocidental, Brazil (Lat/Long -16.0772, -47.9264) throughout the year, you should tilt your panels at an angle of 16° 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 Cidade Ocidental, 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 Cidade Ocidental, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
0° in Summer	22° North in Autumn	32° North in Winter	11° 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 Cidade Ocidental, 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 Cidade Ocidental, Brazil.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Cidade Ocidental, Brazil

The region surrounding Cidade Ocidental in Brazil presents a distinctive topographical profile characteristic of Brazil's Central Plateau (Planalto Central). Located in Goiás state near the border with the Federal District, Cidade Ocidental sits approximately 16 degrees south of the equator at an elevation of roughly 1,050 meters above sea level. The landscape forms part of the broader Brazilian Highlands, featuring a combination of gently rolling hills, plateaus, and shallow valleys. The terrain around Cidade Ocidental is characterized by moderate relief with gradual elevation changes rather than dramatic mountainous features. This undulating landscape includes open areas interspersed with cerrado vegetation - Brazil's tropical savanna ecosystem that features scattered trees with twisted trunks and shrubby undergrowth. The region experiences well-defined wet and dry seasons, with the dry season typically extending from May to September, creating favorable conditions for solar energy capture during this period.

Topographical Features Influencing Solar Potential

The predominant topographical features include extensive plateaus (chapadas) with relatively flat surfaces that extend for considerable distances. These plateaus are occasionally interrupted by shallow valleys formed by the region's drainage system, including tributaries that eventually feed into larger river basins. The soil composition tends toward lateritic types, reddish in color due to high iron oxide content, with varying degrees of fertility. From a solar energy perspective, the combination of elevation, relatively clear atmospheric conditions during the dry season, and abundant flat or gently sloping terrain creates fundamentally favorable conditions for photovoltaic installations. The higher elevation means thinner atmosphere, allowing for more direct solar radiation to reach ground-based collectors.

Optimal Areas for Large-Scale Solar Development

The most suitable areas for large-scale solar PV development in proximity to Cidade Ocidental would be the extensive plateau regions, particularly those: To the east and northeast of the city, where larger tracts of flat to gently sloping terrain exist with minimal current agricultural utilization. These areas benefit from good solar exposure throughout the day with limited shadowing effects from topographical features. The elevated plains extending southward from Cidade Ocidental also present excellent potential, with abundant land that features minimal slope and good drainage characteristics. These areas typically have less dense vegetation and fewer competing land uses. Areas to avoid would include the more dissected terrain with steeper slopes found in some of the drainage corridors, as well as locations with denser cerrado vegetation that would require extensive clearing. The region's road network, centered around BR-040 highway, provides reasonable access to many of these potential development areas, though additional infrastructure development would be necessary for utility-scale projects. The proximity to Brasília's metropolitan area (approximately 45 kilometers to the northwest) represents a significant advantage for power transmission and distribution considerations. The Central Plateau's characteristic dry season climate pattern enhances the region's suitability for solar energy capture, with minimal cloud cover during winter months. The transition seasons also offer substantial solar potential, though the summer wet season brings increased cloud cover that would somewhat reduce generation capacity during those months.

Brazil solar PV Stats as a country
