Kelly Village, Tunapuna/Piarco, located in Trinidad and Tobago, offers a promising environment for solar energy generation due to its tropical location. The consistent sunlight throughout the year provides a stable foundation for solar PV systems to operate effectively.

Seasonal Solar Performance

The solar energy output at Kelly Village remains relatively consistent across all seasons, with only minor fluctuations. Autumn sees the highest production at 6.01 kWh/day per kW installed, followed closely by Spring at 5.94 kWh/day. Summer and Winter show slightly lower outputs at 5.75 kWh/day and 5.46 kWh/day, respectively. This minimal seasonal variation is characteristic of tropical regions, where the sun's path across the sky remains relatively constant throughout the year. The difference between the highest and lowest producing seasons is only 0.55 kWh/day, indicating a stable and reliable solar energy potential year-round.

Optimal Panel Tilt

For fixed panel installations in Kelly Village, Tunapuna/Piarco, the ideal tilt angle to maximize year-round solar 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 Kelly Village's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. High humidity: The tropical climate can lead to increased moisture in the air, potentially affecting solar panel efficiency and longevity. 2. Heavy rainfall: Trinidad and Tobago experiences a wet season, which could temporarily reduce solar output due to cloud cover and rain. To mitigate these factors, consider the following preventative measures:

• Use high-quality, weather-resistant solar panels designed for tropical climates
• Implement regular cleaning and maintenance schedules to prevent dust and debris accumulation
• Install proper drainage systems to prevent water accumulation on or around the panels
• Consider micro-inverters or power optimizers to minimize the impact of partial shading during cloudy periods

By addressing these environmental factors and implementing appropriate measures, Kelly Village can harness its significant solar potential effectively, providing a reliable and sustainable source of 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 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 Kelly Village

Seasonal solar PV output for Latitude: 10.5893, Longitude: -61.3539 (Kelly Village, 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 Kelly Village, Trinidad And Tobago

To maximize your solar PV system's energy output in Kelly Village, Trinidad And Tobago (Lat/Long 10.5893, -61.3539) 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 Kelly Village, 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 Kelly Village, 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	16° South in Autumn	26° South in Winter	4° 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 Kelly Village, 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 Kelly Village, Trinidad And Tobago.

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 Kelly Village, Trinidad And Tobago

Kelly Village is located in the central plains region of Trinidad, situated in a relatively flat area with gentle undulations. The surrounding landscape is characterized by low-lying terrain, with elevations generally ranging from 10 to 30 meters above sea level. The area is part of the Caroni Plains, a broad alluvial plain that stretches across much of central Trinidad. The topography around Kelly Village is predominantly level, with occasional small hills and shallow depressions. The nearby Caroni River and its tributaries have shaped the landscape over time, creating a network of natural drainage channels and some marshy areas. To the north and east of Kelly Village, the terrain gradually rises towards the Northern Range, a series of hills and mountains that form the backbone of Trinidad's northern coast.

Potential for Solar PV Development

The flat and open nature of the landscape surrounding Kelly Village makes it potentially suitable for large-scale solar PV installations. Several nearby areas could be considered for such projects: The expansive agricultural lands to the south and southwest of Kelly Village offer significant potential for solar development. These areas are largely flat, with minimal shading from vegetation or structures, providing ideal conditions for solar panel placement. The existing road network in this region would also facilitate construction and maintenance access. To the east and southeast of Kelly Village, there are open areas that were previously used for sugar cane cultivation. These lands, now mostly fallow, present opportunities for repurposing as solar farms. The relatively uniform terrain and lack of dense forest cover make these locations attractive for large-scale solar installations. The gently sloping areas to the north of Kelly Village, as the land begins to rise towards the Northern Range, could also be suitable for solar PV development. While not as flat as the southern plains, these locations still offer good solar exposure and could accommodate sizeable installations with some minor terrain adjustments. It's important to note that any large-scale solar PV project would need to consider factors beyond topography, such as proximity to electrical infrastructure, environmental impact, and local land use regulations. Additionally, the high humidity and occasional severe weather events in the region would require careful planning and robust equipment selection to ensure the longevity and efficiency of solar installations.
