Puerto Plata, Dominican Republic, located at 19.8058° N, -70.6785° W, offers a promising environment for solar energy generation throughout the year. This tropical location benefits from consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than significant temperature fluctuations.

Solar Energy Potential

The solar energy potential in Puerto Plata is relatively stable across seasons, with some variations: Spring sees the highest average daily output at 6.67 kWh per kW of installed solar capacity, closely followed by Summer at 6.60 kWh/day. Autumn experiences a slight decrease to 5.74 kWh/day, while Winter shows the lowest output at 5.10 kWh/day. These figures indicate that Puerto Plata maintains good solar energy potential year-round, with peak production occurring during Spring and Summer months.

Optimal Panel Placement

For fixed solar panel installations in Puerto Plata, the ideal tilt angle to maximize year-round energy production is 18 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 seasons.

Environmental and Weather Considerations

While Puerto Plata's tropical climate is generally favorable for solar energy production, there are some factors to consider: 1. Hurricane season: The Atlantic hurricane season, typically from June to November, can pose a risk to solar installations. Strong winds and heavy rainfall may damage panels or reduce their efficiency. 2. High humidity: The tropical climate's high humidity levels can potentially lead to accelerated wear on solar equipment and electrical components. To mitigate these risks, several preventative measures can be taken:

• Use hurricane-resistant mounting systems and high-quality, durable panels designed to withstand extreme weather conditions.
• Implement a regular maintenance schedule to check for and address any humidity-related issues.
• Install proper drainage systems to prevent water accumulation on or around the solar panels.
• Consider using corrosion-resistant materials for all components exposed to the elements.

By addressing these factors during the installation process and maintaining the system properly, solar energy production in Puerto Plata can be optimized, 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 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 Puerto Plata

Seasonal solar PV output for Latitude: 19.8058, Longitude: -70.6785 (Puerto Plata, 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 18° South in Puerto Plata, Dominican Republic

To maximize your solar PV system's energy output in Puerto Plata, Dominican Republic (Lat/Long 19.8058, -70.6785) throughout the year, you should tilt your panels at an angle of 18° 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 Puerto Plata, 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 Puerto Plata, Dominican Republic. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
4° South in Summer	25° South in Autumn	35° South in Winter	13° 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 Puerto Plata, 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 Puerto Plata, 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 Puerto Plata, Dominican Republic

The topography around Puerto Plata, Dominican Republic, is quite diverse and picturesque. The city itself is situated on the northern coast of the country, nestled between the Atlantic Ocean and the Cordillera Septentrional mountain range. This creates a stunning backdrop of lush, green mountains rising dramatically from the coastal plains.

Immediately surrounding Puerto Plata, you'll find relatively flat coastal areas with sandy beaches and gentle slopes. As you move inland, the terrain gradually becomes more hilly and eventually transitions into the steep slopes of the mountains. The Cordillera Septentrional, also known as the Northern Mountain Range, runs parallel to the coast and reaches heights of over 2,500 feet in some areas near Puerto Plata.

The region also features several rivers and streams that flow from the mountains to the sea, creating fertile valleys and occasionally steep ravines. These waterways have shaped the landscape over time, carving out interesting geological features and contributing to the area's biodiversity.

Areas Suitable for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Puerto Plata, there are several factors to consider. The most suitable areas would generally be:

1. The coastal plains: These flat or gently sloping areas to the east and west of Puerto Plata offer ample space and consistent sunlight exposure. They're easily accessible and have fewer natural obstacles that might cast shadows on solar panels.

2. Elevated plateaus: Some of the lower foothills of the Cordillera Septentrional may provide ideal locations for solar farms. These areas often have good sun exposure and are less likely to be affected by coastal weather patterns.

3. Cleared agricultural land: Former agricultural areas that are no longer in use could be repurposed for solar installations. These are often relatively flat and already have some infrastructure in place.

It's important to note that while the mountainous areas receive plenty of sunlight, their steep slopes and dense vegetation make them less suitable for large-scale solar projects. Additionally, any potential sites would need to be evaluated for their proximity to the electrical grid, environmental impact, and local zoning regulations before being developed for solar PV use.
