Porto de Pedras, Brazil, located along the northeastern coast of the country, presents a promising location for solar energy generation throughout the year. This tropical location benefits from consistent sunlight patterns that make it suitable for photovoltaic (PV) systems. The seasonal energy production shows interesting variations throughout the year. During spring, the location achieves its peak performance with an average of 7.27 kWh per day for each kilowatt of installed solar capacity. Summer follows closely with 7.02 kWh/day, while autumn sees a moderate decrease to 6.10 kWh/day. Winter represents the lowest production period, though still respectable at 5.28 kWh/day per installed kilowatt.

Optimal Panel Installation

For fixed solar panel installations in Porto de Pedras, the ideal tilt angle to maximize year-round energy production is 8 degrees facing North. This specific angle has been calculated to optimize solar capture across the changing seasons, accounting for the site's tropical latitude and the Earth's elliptical orbit.

Seasonal Considerations

The spring-summer period (approximately September through February) represents the prime solar generation window for Porto de Pedras, with daily production exceeding 7 kWh per installed kilowatt. While winter shows reduced output, the decrease is less dramatic than in locations further from the equator, demonstrating the advantage of Porto de Pedras' tropical setting.

Environmental and Weather Considerations

Several environmental factors may impact solar production in Porto de Pedras:

• Coastal humidity and salt spray can accelerate corrosion of solar equipment and potentially reduce panel efficiency over time.
• The region's wet season can bring extended cloud cover that temporarily reduces solar output.
• Tropical vegetation growth may create shading issues if not regularly maintained.

Recommended Preventative Measures

To maximize solar production in this location, several preventative measures are advisable:

• Install marine-grade components designed to withstand salt exposure and high humidity
• Implement regular cleaning protocols to remove salt deposits and debris
• Consider slightly oversizing systems to accommodate reduced production during cloudier periods
• Establish vegetation management plans to prevent shading from rapid tropical plant growth
• Use corrosion-resistant mounting hardware and protective coatings for all exposed metal components

With these considerations addressed, Porto de Pedras offers excellent year-round solar potential with relatively consistent production across seasons compared to non-tropical locations.

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 Porto De Pedras

Seasonal solar PV output for Latitude: -9.112, Longitude: -35.3926 (Porto De Pedras, 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 8° North in Porto De Pedras, Brazil

To maximize your solar PV system's energy output in Porto De Pedras, Brazil (Lat/Long -9.112, -35.3926) throughout the year, you should tilt your panels at an angle of 8° 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 Porto De Pedras, 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 Porto De Pedras, Brazil. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 8° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
7° South in Summer	15° North in Autumn	25° North in Winter	3° 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 Porto De Pedras, 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 Porto De Pedras, 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 Porto De Pedras, Brazil

Porto de Pedras is a small coastal municipality located in the state of Alagoas, northeastern Brazil. The topography of this region is characterized by a diverse landscape that transitions from coastal plains to gently rolling hills as one moves inland from the Atlantic Ocean.

Coastal Features

The immediate coastal area of Porto de Pedras features sandy beaches backed by low-lying coastal plains. These plains are relatively flat and extend several kilometers inland before the terrain begins to rise. The municipality sits at the mouth of the Manguaba River, creating an estuarine environment where freshwater meets the sea. This coastal zone includes mangrove ecosystems and coastal lagoons that are typical of Brazil's northeast coast.

Inland Terrain

Moving away from the coast, the landscape gradually transforms into undulating terrain with modest hills. These hills rarely exceed 100 meters in elevation but provide subtle variations in the topography. The soil in this region is predominantly derived from sedimentary deposits, with areas of sandy and clay-rich compositions. The vegetation transitions from coastal species to more drought-resistant plants as one moves further inland, reflecting the shift toward a drier climate away from the maritime influence. The natural vegetation of the region belongs to the Atlantic Forest biome, though much of the original forest has been cleared for agriculture, particularly sugarcane cultivation, which dominates the rural landscape around Porto de Pedras.

Hydrography

The area is crossed by several small rivers and streams that flow eastward toward the Atlantic Ocean. The Manguaba River is the most significant water body in the vicinity. The hydrography of the region influences the local topography, with river valleys creating natural depressions in the otherwise gently rolling landscape.

Potential for Solar PV Development

When considering areas near Porto de Pedras for large-scale solar photovoltaic (PV) development, several factors related to topography come into play. The inland areas with gently rolling hills offer promising locations for solar farms for several reasons. The slightly elevated terrain located 5-15 kilometers inland from Porto de Pedras presents optimal conditions for solar PV installation. These areas benefit from: 1. Reduced risk of flooding compared to the coastal lowlands 2. Better drainage during the rainy season 3. Fewer tall vegetation obstacles that could cast shadows on solar panels 4. Reduced salt spray exposure compared to immediate coastal locations The gently sloping hillsides facing north or northeast would be particularly advantageous for solar PV placement, as they receive consistent sunlight throughout the day. Additionally, these inland areas typically have less cloud cover than the immediate coast, where sea breezes can generate localized cloud formations.

Terrain Considerations

The agricultural lands currently used for sugarcane cultivation represent potential conversion opportunities for solar development. These areas have already been cleared of native vegetation and have established access roads, reducing the environmental impact and infrastructure costs of new solar installations. Areas to avoid would include the immediate coastal zone with its environmental sensitivity, flood-prone river valleys, and any steeper slopes that would require excessive grading. The mangrove ecosystems near the Manguaba River estuary should be preserved for their ecological value and would not be suitable for development. The relatively stable geological conditions of the region, with limited risk of landslides or significant erosion on the gentle inland hills, further enhance the suitability of these areas for large-scale solar infrastructure that requires long-term ground stability.

Brazil solar PV Stats as a country
