La Golondrina, Azua Province, Dominican Republic, located at 18.5313° N, -70.7945° W, offers a promising 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 PV systems in La Golondrina demonstrate strong performance across all seasons. Spring yields the highest daily output at 6.89 kWh per kW of installed capacity, closely followed by summer at 6.61 kWh/day. Autumn and winter show slightly lower but still substantial outputs of 5.94 kWh/day and 5.47 kWh/day, respectively.

Optimal Panel Positioning

For fixed panel installations in La Golondrina, Azua Province, the ideal tilt angle to maximize year-round solar production is 17 degrees facing South. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Peak Generation Periods

The most productive periods for solar energy generation in La Golondrina are during spring and summer. These seasons offer longer daylight hours and more direct sunlight, resulting in higher energy yields. However, the relatively small variation in output across seasons indicates that solar PV systems can operate efficiently year-round in this location.

Environmental Considerations

While La Golondrina's tropical climate is generally favorable for solar energy production, there are some environmental factors to consider: 1. Hurricanes and tropical storms: The Dominican Republic is prone to these weather events, which can potentially damage solar installations. 2. High humidity and rainfall: These conditions may lead to increased dust and debris accumulation on panels, potentially reducing efficiency. To mitigate these risks, several preventative measures can be implemented:

• Use hurricane-resistant mounting systems and high-quality, durable panels
• Install adequate drainage systems to prevent water accumulation
• Implement regular cleaning and maintenance schedules
• Consider micro-inverter systems for better performance in partially shaded conditions

By addressing these factors, solar installations in La Golondrina can maintain high efficiency and durability, making the most of the location's excellent solar potential 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 27 locations across Dominican Republic. 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 La Golondrina

Seasonal solar PV output for Latitude: 18.5313, Longitude: -70.7945 (La Golondrina, Dominican Republic), 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 17° South in La Golondrina, Dominican Republic

To maximize your solar PV system's energy output in La Golondrina, Dominican Republic (Lat/Long 18.5313, -70.7945) throughout the year, you should tilt your panels at an angle of 17° 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 La Golondrina, Dominican Republic

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 La Golondrina, Dominican Republic. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 17° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
3° South in Summer	24° South in Autumn	34° South in Winter	12° 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 La Golondrina, Dominican Republic

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 La Golondrina, Dominican Republic.

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 La Golondrina, Dominican Republic

The area surrounding La Golondrina in the Dominican Republic is characterized by diverse and rugged topography. This region is part of the Cordillera Central mountain range, which dominates much of the country's interior. The landscape near La Golondrina features a mix of steep hills, rolling slopes, and narrow valleys. The terrain in this area is generally mountainous, with elevations varying significantly over short distances. The hills and mountains are often covered in lush vegetation, typical of the tropical climate found in the Dominican Republic. Small streams and rivers wind their way through the valleys, contributing to the area's complex topography.

Solar PV Potential

When considering large-scale solar PV installations near La Golondrina, it's important to look for areas that offer relatively flat or gently sloping terrain. While the immediate vicinity of La Golondrina may be too mountainous for extensive solar farms, there are potential sites in the broader region that could be suitable. The most promising areas for solar PV development would likely be found in the wider valleys or on plateaus within the mountain range. These locations offer more level ground and potentially receive consistent sunlight throughout the day. Additionally, areas where deforestation has already occurred might be considered, as they would require less land clearing and have a smaller environmental impact. It's worth noting that while the mountainous terrain presents challenges for large-scale solar installations, it may also offer opportunities for smaller, distributed solar projects. These could take advantage of south-facing slopes that receive ample sunlight. Any solar development in this region would need to carefully consider factors such as accessibility for construction and maintenance, proximity to existing power infrastructure, and potential environmental impacts. Given the complex topography, detailed site surveys would be essential to identify the most suitable locations for solar PV projects in the vicinity of La Golondrina.
