Amaury, Rivière du Rempart District, Mauritius presents a reasonably good location for year-round solar PV energy generation, though with some notable seasonal variations that potential solar installers should understand.

Seasonal Solar Performance

The solar energy output at this tropical location shows distinct patterns throughout the year. Summer delivers the strongest performance at 7.82 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows closely behind with 7.23 kWh per day, creating an extended period of excellent solar production spanning roughly six months of the year. However, the location experiences significantly reduced solar output during the cooler months. Autumn drops to 5.45 kWh per day, while winter reaches the lowest point at just 4.62 kWh per day per kW installed. This represents a substantial 41% decrease from summer peak performance to winter minimum.

Optimal Installation Setup

For maximum year-round energy production at Amaury, Rivière du Rempart District, solar panels should be installed at a fixed tilt angle of 17 degrees facing north. This angle has been calculated to optimize total annual solar output by accounting for the sun's changing position throughout the year and the location's specific latitude.

Environmental and Weather Challenges

Being located in the tropics, Amaury faces several environmental factors that can impact solar panel performance and require careful consideration during installation:

• Tropical cyclones and high winds: Mauritius lies in a cyclone-prone region, particularly during the summer months when solar production is at its peak
• Heavy rainfall and humidity: The tropical climate brings intense rainfall periods and consistently high humidity levels
• Salt air corrosion: The island location means constant exposure to salt-laden ocean air
• Dust and debris accumulation: Tropical weather patterns can deposit organic matter and dust on panel surfaces

Preventative Installation Measures

To maximize solar energy production despite these challenges, several protective measures should be implemented:

• Reinforced mounting systems: Use heavy-duty mounting hardware and foundations designed to withstand cyclonic winds
• Corrosion-resistant materials: Select aluminum or stainless steel components with marine-grade coatings to resist salt air damage
• Proper drainage design: Ensure mounting systems allow efficient water runoff during heavy tropical rains
• Regular cleaning schedule: Implement frequent panel cleaning to remove salt deposits, dust, and organic debris that reduce efficiency
• Quality inverters with protection: Install inverters in weatherproof enclosures with adequate ventilation for the humid conditions

Despite these environmental challenges, Amaury's consistent tropical sunlight and strong summer/spring solar production make it a viable location for solar PV installation when proper precautions are taken during setup and maintenance.

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 Amaury

Seasonal solar PV output for Latitude: -20.1343, Longitude: 57.6612 (Amaury, Mauritius), 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 17° North in Amaury, Mauritius

To maximize your solar PV system's energy output in Amaury, Mauritius (Lat/Long -20.1343, 57.6612) throughout the year, you should tilt your panels at an angle of 17° 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 Amaury, Mauritius

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 Amaury, Mauritius. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° North in Summer	26° North in Autumn	36° North in Winter	13° 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 Amaury, Mauritius

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 Amaury, Mauritius.

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 Amaury, Mauritius

Topographical Features Around Amaury

Amaury is situated in the northern region of Mauritius, positioned within the Pamplemousses district on this volcanic island nation. The topography around Amaury is characterized by relatively gentle, undulating terrain that forms part of the island's northern coastal plain. This area sits at a modest elevation, with the landscape gradually rising from the nearby coastline toward the island's interior highlands.

The terrain consists primarily of former sugar cane plantation lands, creating expansive open areas with minimal natural obstacles. The volcanic origins of Mauritius have created fertile, well-drained soils in this region, though the ancient lava flows have also resulted in some scattered rocky outcrops and gentle ridges that punctuate the otherwise smooth topography.

Moving inland from Amaury, the landscape begins to show more pronounced elevation changes as it approaches the central plateau region. To the south and southeast, the terrain becomes progressively more mountainous, leading toward the dramatic peaks that dominate Mauritius's interior, including the Moka Range and the island's highest elevations.

Optimal Areas for Large-Scale Solar Development

The expansive flatlands extending westward and southward from Amaury present the most favorable conditions for large-scale solar photovoltaic installations. These former agricultural areas offer vast, relatively level spaces that would require minimal grading or terrain modification for solar panel deployment. The gentle slopes in this region provide natural drainage while maintaining optimal angles for panel positioning.

The coastal plain areas between Amaury and the settlements of Goodlands and Grand Baie to the west contain particularly suitable terrain. These locations benefit from consistent topographical conditions and are largely free from the shading effects that might be caused by significant elevation changes or dense vegetation. The open character of this landscape, shaped by decades of agricultural use, provides clear sight lines and minimal obstructions.

Areas toward the interior, particularly in the direction of Arsenal and Poudre d'Or, also demonstrate excellent potential for solar development. The terrain here remains relatively flat while offering slightly higher elevations that can enhance exposure conditions. These inland locations are sufficiently removed from coastal weather influences while maintaining the topographical advantages of the northern plain.

The region's volcanic soil composition provides stable foundations for solar infrastructure, while the generally consistent elevation profile across large areas would allow for efficient installation and maintenance access. The absence of significant water features or wetlands in the immediate vicinity further enhances the development potential of these areas for renewable energy projects.
