Lamentin, Guadeloupe, located in the Caribbean tropics, offers a favorable environment for solar energy generation throughout the year. This location benefits from consistent sunlight and experiences wet and dry seasons rather than traditional four-season weather patterns.

Seasonal Solar Production

Solar energy production in Lamentin remains relatively stable across all seasons, with some variations:

• Spring: 6.96 kWh/day (highest output)
• Summer: 6.66 kWh/day
• Autumn: 6.12 kWh/day
• Winter: 5.57 kWh/day (lowest output)

These figures represent the expected daily electricity output per kilowatt of installed solar capacity. The consistent year-round production makes Lamentin an excellent location for solar PV installations.

Optimal Panel Angle

For fixed solar panel installations in Lamentin, the ideal tilt angle to maximize year-round energy production is 15 degrees facing South. This angle takes into account the location's latitude and the sun's position throughout the year, ensuring optimal sunlight capture across all seasons.

Environmental Considerations

While Lamentin's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider:

1. Hurricanes: The Caribbean region is prone to hurricanes, which can potentially damage solar installations. To mitigate this risk, solar panels should be installed using hurricane-resistant mounting systems and frames designed to withstand high winds.

2. High humidity: The tropical climate brings high humidity levels, which can lead to corrosion of solar equipment over time. Using corrosion-resistant materials and applying protective coatings can help extend the lifespan of solar installations in this environment.

3. Heavy rainfall: During the wet season, frequent and heavy rainfall may temporarily reduce solar output. Installing panels at the optimal angle helps with water runoff and self-cleaning. Additionally, regular maintenance and cleaning can prevent any long-term impact on energy production.

By addressing these factors during installation and maintenance, solar energy systems in Lamentin can operate efficiently and reliably, taking full advantage of the location's abundant sunlight 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 4 locations across Guadeloupe. This analysis provides insights into each city/location's potential for harnessing solar energy through PV installations.

Solar output per kW of installed solar PV by season in Lamentin

Seasonal solar PV output for Latitude: 16.2729, Longitude: -61.6275 (Lamentin, Guadeloupe), 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 15° South in Lamentin, Guadeloupe

To maximize your solar PV system's energy output in Lamentin, Guadeloupe (Lat/Long 16.2729, -61.6275) throughout the year, you should tilt your panels at an angle of 15° South 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 Lamentin, Guadeloupe

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 Lamentin, Guadeloupe. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 15° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
1° South in Summer	22° South in Autumn	32° South in Winter	10° South 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 Lamentin, Guadeloupe

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 Lamentin, Guadeloupe.

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 Lamentin, Guadeloupe

The area around Lamentin, Guadeloupe, is characterized by a diverse and varied topography. Situated on the western side of Basse-Terre island, Lamentin is nestled between the Caribbean Sea and the lush, mountainous interior of Guadeloupe. The landscape gradually transitions from coastal lowlands to rolling hills and eventually to steep, forested slopes as you move inland. Near the coast, the terrain is relatively flat, with gentle slopes and low-lying areas. This coastal plain is dotted with small streams and rivers that flow from the higher elevations towards the sea. As you move eastward from Lamentin, the land begins to rise more noticeably, forming a series of undulating hills and valleys.

Mountainous Interior

Further inland, the topography becomes increasingly rugged and mountainous. The central part of Basse-Terre is dominated by the Soufrière massif, a volcanic mountain range that includes La Grande Soufrière, the highest peak in the Lesser Antilles. These mountains are covered in dense tropical rainforest, creating a stark contrast to the more developed coastal areas.

Potential for Solar PV

When considering areas suitable for large-scale solar PV installations near Lamentin, the coastal plains and gently sloping hills offer the most promise. These areas provide relatively flat terrain that is ideal for the placement of solar panels. The open spaces in the agricultural lands surrounding Lamentin could potentially be repurposed or shared for solar energy production. The regions to the north and south of Lamentin, extending along the coast, present favorable conditions for solar PV development. These areas benefit from consistent sunshine and have fewer geographical obstacles compared to the mountainous interior. Additionally, the proximity to existing infrastructure and population centers makes these coastal zones attractive for energy distribution. However, it's important to note that while the flatter coastal areas are most suitable for large-scale solar installations, careful consideration must be given to environmental factors such as potential flooding risks and the impact on local ecosystems. Any development would need to balance energy production goals with conservation efforts to protect Guadeloupe's unique natural habitats.
