Plaine Magnien, Grand Port District, Mauritius, located at latitude -20.4217 and longitude 57.6738, offers a promising environment for solar energy generation throughout the year. Situated in the tropics, this location benefits from relatively consistent sunlight, with seasons characterized more by wet and dry periods rather than significant temperature fluctuations.

Seasonal Solar Performance

The solar energy potential in Plaine Magnien varies across the seasons, with summer and spring being the most productive periods. During summer, solar panels can generate an impressive 7.81 kWh per day for each kilowatt of installed capacity. Spring follows closely with 7.20 kWh/day. Autumn sees a moderate decrease to 5.44 kWh/day, while winter experiences the lowest output at 4.62 kWh/day per kilowatt installed.

These figures indicate that Plaine Magnien is well-suited for year-round solar energy production, with particularly favorable conditions from late spring through early autumn. The relatively small variation between seasons suggests a reliable and consistent energy supply throughout the year.

Optimal Panel Installation

To maximize solar energy capture in Plaine Magnien, Grand Port District, fixed solar panels should be tilted at an angle of 18 degrees facing North. This orientation ensures optimal exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Plaine Magnien offers favorable conditions for solar energy production, there are some environmental factors to consider: 1. Tropical cyclones: Mauritius can experience cyclones, typically between November and April. 2. Heavy rainfall: The wet season, generally from January to March, may bring periods of reduced sunlight.

To mitigate these challenges, solar installations should incorporate sturdy mounting systems capable of withstanding high winds. Additionally, using high-quality, water-resistant panels and ensuring proper drainage can help maintain efficiency during periods of heavy rainfall. Regular cleaning and maintenance of panels, especially after storms or during the dry season when dust accumulation is more likely, can also help optimize energy production.

Overall, Plaine Magnien presents an excellent location for solar PV installations, with its tropical climate providing ample sunlight throughout the year. With proper planning and preventative measures, the environmental challenges can be effectively managed, allowing for efficient and reliable solar energy generation.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

So far, we have conducted calculations to evaluate the solar photovoltaic (PV) potential in 41 locations across Mauritius. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Ideally tilt fixed solar panels 18° North in Plaine Magnien, Mauritius

To maximize your solar PV system's energy output in Plaine Magnien, Mauritius (Lat/Long -20.4217, 57.6738) throughout the year, you should tilt your panels at an angle of 18° 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 Plaine Magnien, 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 Plaine Magnien, Mauritius. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° 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	14° 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 Plaine Magnien, 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 Plaine Magnien, 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 Plaine Magnien, Mauritius

The topography around Plaine Magnien, Mauritius, is characterized by a relatively flat coastal plain that gradually rises towards the interior of the island. This area is situated in the southeastern part of Mauritius, known for its gently undulating terrain and expansive sugarcane fields. The landscape is predominantly low-lying, with elevations typically ranging from sea level to about 50 meters above sea level. To the west and northwest of Plaine Magnien, the terrain becomes slightly more elevated and hilly as it transitions towards the central plateau of Mauritius. This gradual increase in elevation creates a subtle rolling landscape dotted with small hills and shallow valleys. Despite these minor variations, the overall topography remains relatively gentle and accessible. The coastline near Plaine Magnien features sandy beaches and coral reefs, typical of the island's eastern shore. The area is also home to the Sir Seewoosagur Ramgoolam International Airport, which occupies a large, flat expanse of land, further emphasizing the level nature of the local topography.

Suitability for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The flat to gently sloping terrain surrounding Plaine Magnien offers excellent potential for solar energy development. The following areas stand out as particularly suitable: The expansive sugarcane fields to the north and west of Plaine Magnien present an ideal location for solar PV installations. These areas benefit from their flat topography, which simplifies construction and maximizes sun exposure throughout the day. Additionally, the existing agricultural use means that the land is already cleared and easily accessible. The slightly elevated regions to the northwest, as the land rises towards the central plateau, could also be well-suited for solar PV. These areas may receive less cloud cover compared to the immediate coastal zones, potentially increasing solar energy yield. The gentle slopes in this direction can be advantageous for optimal panel orientation without requiring significant earthwork. Areas to the south and southeast of Plaine Magnien, extending towards the coast but set back from the immediate shoreline, could also be considered. While these locations might be more exposed to coastal weather patterns, they offer vast stretches of relatively flat land that could accommodate large solar arrays. It's important to note that while the topography is favorable, any large-scale solar PV project would need to carefully consider other factors such as proximity to the electrical grid, environmental impact, and land-use regulations. The presence of the international airport nearby may also impose height restrictions or other limitations on development in certain areas.
