Aguada, Puerto Rico, situated at 18.3777° N, 67.1966° W, offers a promising location for solar energy generation throughout the year. This tropical setting 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 output in Aguada demonstrates a favorable year-round performance. Spring emerges as the most productive season, yielding an impressive 7.14 kWh per day for each kilowatt of installed solar capacity. Summer follows closely with 6.74 kWh/day, while autumn and winter show slightly lower but still substantial outputs of 6.03 kWh/day and 5.48 kWh/day, respectively. These figures indicate that Aguada maintains a strong solar potential throughout the year, with only moderate fluctuations between seasons. The location's proximity to the equator ensures a relatively stable solar resource, making it an excellent candidate for consistent solar energy production.

Optimal Panel Installation

To maximize year-round solar energy production in Aguada, fixed solar panels should be tilted at a 17-degree angle facing south. This optimal tilt angle has been calculated considering the location's latitude, daily solar elevation angles, and weighted by NASA's solar irradiance data to account for the Earth's elliptical orbit.

Environmental Considerations

While Aguada presents favorable conditions for solar energy generation, there are some environmental factors to consider: 1. Hurricane risk: Puerto Rico is susceptible to hurricanes, which can potentially damage solar installations. 2. High humidity: The tropical climate may lead to increased moisture-related issues. To mitigate these risks, the following preventative measures can be implemented: • Use hurricane-resistant mounting systems and high-quality, durable panels. • Install proper drainage systems to prevent water accumulation. • Employ corrosion-resistant materials for all components. • Implement regular maintenance schedules to address any humidity-related issues promptly. By taking these precautions, solar installations in Aguada can maintain high energy production levels while withstanding local 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 42 locations across Puerto Rico. 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 Aguada

Seasonal solar PV output for Latitude: 18.3777, Longitude: -67.1966 (Aguada, Puerto Rico), 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 Aguada, Puerto Rico

To maximize your solar PV system's energy output in Aguada, Puerto Rico (Lat/Long 18.3777, -67.1966) 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 Aguada, Puerto Rico

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 Aguada, Puerto Rico. 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
2° 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 Aguada, Puerto Rico

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 Aguada, Puerto Rico.

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 Aguada, Puerto Rico

The topography around Aguada, Puerto Rico, is characterized by a diverse landscape that transitions from coastal plains to hilly terrain. Located on the northwestern coast of the island, Aguada features a relatively flat coastal area that gradually rises into gentle slopes and rolling hills as you move inland.

Near the shore, you'll find sandy beaches and low-lying areas that are part of the coastal plain. This flat terrain extends for a short distance before the landscape begins to change. As you travel east and southeast from the coast, the elevation starts to increase, and the terrain becomes more varied.

The inland areas of Aguada and its surrounding regions are dominated by a series of hills and small mountains. These elevations are part of the larger hill system that runs through western Puerto Rico. The hills are generally rounded and covered with lush vegetation, typical of the island's tropical climate.

Regarding areas nearby that would be most suited for large-scale solar PV (photovoltaic) installations, the ideal locations would be found in the flatter, more open areas. The coastal plains and gently sloping regions just inland from Aguada could offer suitable sites for solar farms. These areas typically have fewer obstructions that could cast shadows on solar panels and provide easier access for construction and maintenance.

However, it's important to note that Puerto Rico's limited land area and dense population can make finding large, unoccupied spaces challenging. Some of the hillsides with southern exposure might also be considered for solar installations, although these would likely be more complex and expensive to develop due to the terrain.

Any large-scale solar PV project in this region would need to carefully consider factors such as land availability, proximity to the electrical grid, and potential environmental impacts. Additionally, the risk of hurricanes and tropical storms in Puerto Rico means that any solar installation would need to be designed to withstand extreme weather conditions.

Puerto Rico solar PV Stats as a country

Puerto Rico ranks 48th in the world for cumulative solar PV capacity, with 491 total MW's of solar PV installed. Each year Puerto Rico is generating 154 Watts from solar PV per capita (Puerto Rico ranks 33rd in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Puerto Rico?

Yes, there are several incentives for businesses wanting to install solar energy in Puerto Rico. The Puerto Rico Energy Commission (PREC) offers a net metering program that allows businesses to receive credits on their electricity bills for the excess energy they generate from their solar systems. Additionally, businesses may be eligible for federal tax credits and accelerated depreciation benefits. The PREC also provides grants and loans to help offset the cost of installing solar systems.
