Solar PV Analysis of Scarborough, Trinidad And Tobago
Scarborough, Trinidad and Tobago, located in the tropics, offers a promising environment for solar energy generation. This Caribbean location benefits from consistent sunlight throughout the year, with seasons primarily characterized by wet and dry periods rather than traditional temperature-based seasons.
Solar Energy Potential
The solar energy potential in Scarborough is relatively stable across the year, with slight variations between seasons. Spring sees the highest daily output at 6.54 kWh per kW of installed solar capacity, followed closely by autumn at 6.40 kWh/day. Summer produces 6.28 kWh/day, while winter has the lowest output at 5.82 kWh/day. These figures indicate a favorable year-round solar generation potential, with only minor fluctuations between seasons.
Optimal Panel Positioning
For fixed solar panel installations in Scarborough, the ideal tilt angle to maximize year-round energy production is 10 degrees facing South. This angle takes into account the location's latitude and the sun's position throughout the year, ensuring optimal exposure to sunlight across all seasons.
Environmental Considerations
While Scarborough's tropical climate is generally conducive to solar energy production, there are some environmental factors to consider:
- Hurricanes and tropical storms: The Caribbean region is prone to these weather events, which can potentially damage solar installations.
- High humidity and rainfall: These conditions may lead to increased dust and debris accumulation on panels, potentially reducing efficiency.
Preventative Measures
To mitigate these environmental challenges and ensure optimal solar energy production, consider the following measures:
- Install hurricane-resistant mounting systems and high-quality, durable panels designed to withstand strong winds and flying debris.
- Implement regular cleaning and maintenance schedules to combat the effects of humidity and rainfall on panel efficiency.
- Use corrosion-resistant materials for all components to protect against the salt-laden air typical of coastal areas.
- Consider installing a monitoring system to quickly identify and address any performance issues.
By implementing these preventative measures, solar installations in Scarborough can take full advantage of 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 34 locations across Trinidad And Tobago. 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 Scarborough
Seasonal solar PV output for Latitude: 11.1814, Longitude: -60.7368 (Scarborough, Trinidad And Tobago), 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 10° South in Scarborough, Trinidad And Tobago
To maximize your solar PV system's energy output in Scarborough, Trinidad And Tobago (Lat/Long 11.1814, -60.7368) throughout the year, you should tilt your panels at an angle of 10° 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 Scarborough, Trinidad And Tobago
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 Scarborough, Trinidad And Tobago. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 10° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° North in Summer | 17° South in Autumn | 27° South in Winter | 5° 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 Scarborough, Trinidad And Tobago
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 Scarborough, Trinidad And Tobago.
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 Scarborough, Trinidad And Tobago
Scarborough, the capital of Tobago, is situated on the southwestern coast of the island. The topography around Scarborough is characterized by a mix of coastal plains and gently rolling hills that gradually rise towards the island's interior. The town itself is nestled between the Caribbean Sea and the foothills of Tobago's central mountain range.
As you move inland from Scarborough, the terrain becomes more varied and elevated. The landscape transitions from the relatively flat coastal areas to undulating hills and steeper slopes. The central part of Tobago, north and east of Scarborough, features a more rugged topography with higher elevations, including the island's highest point, Pigeon Peak, which stands at about 550 meters (1,804 feet) above sea level.
The areas most suited for large-scale solar PV installations near Scarborough would likely be the flatter, open spaces found in the coastal plains and lower hillsides. These areas offer several advantages for solar energy production. They typically receive more consistent sunlight throughout the day, have fewer obstructions that could cast shadows on solar panels, and are generally more accessible for construction and maintenance purposes.
Potential locations for solar PV projects might include cleared agricultural lands or former sugarcane fields in the southwestern part of the island, near Scarborough and extending towards Crown Point. These areas tend to have gentler slopes and more open terrain. Additionally, some of the less steep hillsides to the north and east of Scarborough could also be suitable, provided they have good sun exposure and are not heavily forested.
It's important to note that while Tobago has good potential for solar energy, any large-scale project would need to carefully consider environmental impacts, land use regulations, and the island's unique ecosystem. Factors such as proximity to the electrical grid, road access, and potential natural hazards (like hurricanes) would also play a crucial role in determining the most suitable locations for solar PV installations in the region.
