Utila, Bay Islands, Honduras, located at 16.0955, -86.8975, offers a promising environment for solar energy generation throughout the year. This tropical island benefits from consistent sunlight, with seasons primarily characterized by wet and dry periods rather than significant temperature variations.

Seasonal Solar Performance

Solar panel efficiency in Utila demonstrates a relatively stable output across the year. Spring and summer months show the highest production, with 6.99 kWh/day and 6.97 kWh/day respectively per kW of installed solar capacity. Autumn sees a slight decrease to 5.73 kWh/day, while winter experiences the lowest output at 5.22 kWh/day. The minimal fluctuation between seasons indicates that Utila is well-suited for year-round solar energy production. The most ideal times for generation are during the spring and summer months, typically from March through August, when daylight hours are longer and skies are generally clearer.

Optimal Panel Positioning

For fixed panel installations in Utila, Bay Islands, the ideal tilt angle to maximize year-round solar production is 14 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 Utila's tropical climate is generally favorable for solar energy, there are some environmental factors to consider: 1. High humidity and salt air exposure due to the coastal location 2. Potential for tropical storms and hurricanes To mitigate these challenges, it's crucial to use corrosion-resistant materials for solar panel frames and mounting systems. Additionally, installing panels with a slight tilt helps prevent water accumulation and facilitates self-cleaning. Implementing a robust mounting system capable of withstanding high winds is essential to protect against potential storm damage. Regular maintenance, including cleaning panels to remove salt deposits, will help maintain optimal performance. Despite these considerations, Utila's consistent sunlight and relatively stable seasonal output make it an excellent location for solar PV installations, with the potential for significant year-round energy production.

Note: The Tropics are located between 23.5° North and -23.5° South of the equator.

Solar output per kW of installed solar PV by season in Utila

Seasonal solar PV output for Latitude: 16.0955, Longitude: -86.8975 (Utila, Honduras), 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 14° South in Utila, Honduras

To maximize your solar PV system's energy output in Utila, Honduras (Lat/Long 16.0955, -86.8975) throughout the year, you should tilt your panels at an angle of 14° 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 Utila, Honduras

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 Utila, Honduras. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 14° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
0° in Summer	21° South in Autumn	31° South in Winter	9° 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 Utila, Honduras

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 Utila, Honduras.

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 Utila, Honduras

Utila, one of the Bay Islands of Honduras, is characterized by a relatively flat topography compared to its neighboring islands. The island itself is mostly low-lying, with its highest point reaching only about 74 meters (243 feet) above sea level. This gentle terrain is primarily composed of mangrove swamps, sandy beaches, and small hills covered in tropical vegetation.

The surrounding waters are part of the Caribbean Sea, featuring coral reefs and shallow lagoons. The seafloor around Utila slopes gradually, creating an extensive area of relatively shallow water before dropping off into deeper parts of the Caribbean.

On the nearby Honduran mainland, the landscape becomes more varied. The coastal areas consist of lowland plains and river deltas, which gradually give way to rolling hills and eventually the rugged mountains of the interior. These mountains, part of the Central American Cordillera, can reach heights of over 2,800 meters (9,200 feet).

Regarding large-scale solar PV installations, the most suitable areas would likely be found on the Honduran mainland rather than on Utila itself. The island's limited land area and importance for tourism and conservation make it less ideal for such projects. On the mainland, the following areas could be considered:

Coastal Plains: The flat, open areas along the northern coast of Honduras offer ample space and consistent sunlight. These regions, particularly in the departments of Atlántida and Colón, could accommodate large solar farms without significant topographical challenges.

Central Valleys: Inland areas with gently rolling terrain, such as parts of the Sula Valley or the Comayagua Valley, could be suitable for solar installations. These locations benefit from higher elevation, which can mean clearer skies and less atmospheric interference.

Southern Honduras: The southern departments, like Choluteca and Valle, experience some of the country's highest levels of solar radiation. While some areas here are hilly, there are also expanses of relatively flat land that could be utilized for solar projects.

It's important to note that while topography is a crucial factor, other considerations such as proximity to power grids, land ownership, environmental impact, and local regulations would also play significant roles in determining the most suitable locations for large-scale solar PV installations.

Honduras solar PV Stats as a country

Honduras ranks 47th in the world for cumulative solar PV capacity, with 514 total MW's of solar PV installed. This means that 12.90% of Honduras's total energy as a country comes from solar PV (that's 1st in the world). Each year Honduras is generating 53 Watts from solar PV per capita (Honduras ranks 52nd in the world for solar PV Watts generated per capita). [source]

Are there incentives for businesses to install solar in Honduras?

Yes, there are incentives for businesses wanting to install solar energy in Honduras. The Honduran government has implemented a number of policies and programs to promote the use of renewable energy sources such as solar power.
