The location of Olivia, Flacq District, Mauritius, situated at latitude -20.2832 and longitude 57.735, presents a favorable environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.
Seasonal Solar Performance
Solar photovoltaic (PV) systems in Olivia demonstrate varying levels of efficiency across the meteorological seasons. Summer yields the highest output at 7.81 kWh per day for each kilowatt of installed capacity. Spring follows closely with 7.20 kWh/day, while autumn and winter show lower but still substantial production at 5.44 kWh/day and 4.62 kWh/day, respectively.Optimal Generation Periods
The most ideal times for solar energy generation in Olivia are during the summer and spring months. These seasons offer longer daylight hours and more direct sunlight, resulting in peak solar panel efficiency. However, the relatively high output even during autumn and winter indicates that solar PV systems can provide significant energy year-round in this location.Panel Tilt Optimization
For fixed solar panel installations in Olivia, Flacq District, the ideal tilt angle to maximize year-round energy production is 17 degrees facing North. This angle has been calculated to optimize the panels' exposure to sunlight throughout the year, taking into account the location's latitude and the Earth's elliptical orbit.Environmental Considerations
While Olivia's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Cyclones: Mauritius is susceptible to tropical cyclones, which can potentially damage solar installations. 2. Heavy rainfall: The wet season may lead to reduced sunlight and temporary decreases in energy production. To mitigate these risks, solar installations should incorporate robust mounting systems designed to withstand high winds. Additionally, using high-quality, water-resistant panels and ensuring proper drainage can help maintain efficiency during periods of heavy rainfall. Regular maintenance, including cleaning panels to remove salt spray and dust, is crucial to maintain optimal performance in this coastal, tropical environment. With these preventative measures in place, Olivia, Flacq District, Mauritius, remains an excellent location for harnessing solar energy throughout the year.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 17° North in Olivia, Mauritius
To maximize your solar PV system's energy output in Olivia, Mauritius (Lat/Long -20.2832, 57.735) 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 Olivia, 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 Olivia, 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 Olivia, 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 Olivia, Mauritius.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Olivia, Mauritius
The topography around Olivia, Mauritius, is characterized by a diverse landscape that reflects the island's volcanic origins. This area, located in the central-eastern part of Mauritius, features a mix of gently rolling hills, small plateaus, and fertile lowlands. The terrain gradually rises from the coastal areas towards the interior, creating a picturesque setting of undulating green fields and scattered patches of forest. To the west of Olivia, the land becomes more elevated, with steeper slopes and deeper valleys. This region is part of the central plateau of Mauritius, which includes some of the island's higher elevations. The vegetation in this area is typically lush, with a combination of native plants and agricultural crops, particularly sugar cane fields that dominate much of the landscape. Towards the east, the terrain becomes flatter as it approaches the coast. This area is characterized by a coastal plain with rich, alluvial soil that supports various agricultural activities. The transition from the hilly interior to the coastal plain is gradual, creating a gentle slope that extends towards the Indian Ocean.
Potential for Large-Scale Solar PV
When considering areas near Olivia for large-scale solar PV installations, the most suitable locations would likely be found in the flatter regions to the east and southeast. These areas offer several advantages for solar energy production: Firstly, the relatively level terrain of the coastal plain provides ample space for the installation of solar panels without the need for extensive land modification. This flat topography also reduces the risk of shading from nearby hills or mountains, ensuring maximum exposure to sunlight throughout the day. Secondly, the proximity to the coast means these areas generally experience fewer cloudy days compared to the more elevated interior regions. This increased solar radiation exposure would contribute to higher energy production efficiency for any solar PV installations. Additionally, the agricultural lands in this region, particularly those used for sugar cane cultivation, could potentially be repurposed or shared for solar energy production. This dual-use approach could provide economic benefits to local farmers while contributing to renewable energy generation. However, it's important to note that any large-scale solar PV project would need to carefully consider environmental impacts, land use regulations, and the need to preserve Mauritius's unique ecosystem. Proper planning and environmental assessments would be crucial to ensure that such developments are sustainable and in harmony with the island's natural beauty and biodiversity.Citation Guide
