Baie Topaze, Rodrigues Island, Mauritius, located at latitude -19.7339732 and longitude 63.3616154, offers a generally favorable environment for solar PV energy generation throughout the year. Situated in the tropics, this location benefits from consistent sunlight and experiences seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

The solar energy output at Baie Topaze varies across the meteorological seasons:

• Summer: 8.13 kWh/day per kW installed
• Spring: 7.39 kWh/day per kW installed
• Autumn: 6.11 kWh/day per kW installed
• Winter: 4.92 kWh/day per kW installed

Optimal Panel Positioning

For fixed panel installations at Baie Topaze, Rodrigues Island, the ideal tilt angle to maximize year-round solar production is 17 degrees facing North. This angle is calculated based on the location's latitude and accounts for the Earth's elliptical orbit, ensuring optimal exposure to sunlight throughout the year.

Environmental Considerations

While Baie Topaze generally offers good conditions for solar energy production, there are some environmental factors to consider: 1. Tropical Cyclones: Mauritius is prone to cyclones, particularly during the summer months (November to April). These storms can potentially damage solar installations if not properly secured. 2. Salt Corrosion: Being a coastal location, salt spray from the ocean can accelerate corrosion of solar equipment.

Preventative Measures

To mitigate these environmental challenges and ensure optimal solar energy production: 1. Install cyclone-resistant mounting systems and use high-quality, weather-resistant solar panels. 2. Regularly clean panels to remove salt deposits and use corrosion-resistant materials for all components. 3. Implement a robust maintenance schedule to quickly address any storm-related damage or salt corrosion issues.

By taking these precautions, solar installations at Baie Topaze can capitalize on the location's favorable solar conditions while minimizing the impact of potential environmental challenges.

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.

Seasonal solar PV output for Latitude: -19.7339732, Longitude: 63.3616154 (Baie Topaze, 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:

Average 8.13kWh/day in Summer.

Average 6.11kWh/day in Autumn.

Average 4.92kWh/day in Winter.

Average 7.39kWh/day in Spring.

Ideally tilt fixed solar panels 17° North in Baie Topaze, Mauritius

To maximize your solar PV system's energy output in Baie Topaze, Mauritius (Lat/Long -19.7339732, 63.3616154) 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.

At Latitude: -19.7339732, Longitude: 63.3616154, the ideal angle to tilt panels is 17° North

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

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 Baie Topaze, 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 Baie Topaze, 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 Baie Topaze, Mauritius

The area around Baie Topaze in Mauritius is characterized by a diverse and picturesque topography. Baie Topaze, which translates to "Topaz Bay," is located on the eastern coast of the island. The coastline in this region features beautiful sandy beaches and crystal-clear waters, typical of Mauritius' renowned tropical landscape.

Moving inland from the bay, the terrain gradually rises into gently rolling hills. These hills are often covered with lush vegetation, including tropical forests and agricultural lands. The elevation increases more significantly as you progress further inland, eventually leading to the island's central plateau.

The central plateau of Mauritius, which is not far from Baie Topaze, is characterized by higher elevations and more rugged terrain. This area includes some of the island's most prominent peaks and volcanic formations, remnants of Mauritius' geological history.

Regarding areas suitable for large-scale solar PV (photovoltaic) installations near Baie Topaze, several factors need to be considered. The most promising locations would likely be found on the gently sloping hillsides and flatlands slightly inland from the coast. These areas offer several advantages for solar energy production:

1. They receive ample sunlight throughout the year, being close to the equator.
2. The terrain is not too steep, making construction and maintenance easier.
3. They are generally less forested than the central regions, reducing the need for land clearing.
4. These areas are often already used for agriculture, potentially allowing for dual-use of the land.

However, it's important to note that any large-scale solar project would need to balance energy production goals with environmental conservation, as Mauritius is known for its unique ecosystems and biodiversity. Additionally, the exact suitability of specific sites would require detailed on-the-ground assessments, considering factors such as local weather patterns, soil stability, and proximity to existing power infrastructure.
