Tumbes, Peru, situated at latitude -3.5693 and longitude -80.4389, offers a promising location for solar energy generation. This tropical region experiences consistent sunlight throughout most of the year, with seasons characterized more by wet and dry periods than temperature variations.

Year-round Solar Potential

The solar energy output at this location remains relatively stable across all seasons. Summer sees the highest production at 5.70 kWh per day for each kilowatt of installed solar capacity. Autumn follows closely with 5.57 kWh/day, while spring yields 5.44 kWh/day. Winter experiences a slight dip but still maintains a respectable 4.80 kWh/day. These figures indicate that Tumbes is an excellent location for year-round solar energy generation. The minimal variation between seasons suggests that solar installations here can provide a consistent and reliable power supply throughout the year.

Optimal Panel Positioning

For fixed panel installations in Tumbes, the ideal tilt angle to maximize year-round solar production is 3 degrees North. This slight tilt helps optimize energy capture across all seasons, taking into account the location's proximity to the equator and the sun's path throughout the year.

Environmental Considerations

While Tumbes presents favorable conditions for solar energy production, there are some environmental factors to consider: 1. Humidity: The tropical climate can lead to high humidity levels, potentially affecting solar panel efficiency and longevity. 2. Coastal proximity: Being near the coast, salt air corrosion could impact solar equipment over time. To mitigate these issues, installers should consider using corrosion-resistant materials and applying protective coatings to solar panels and associated equipment. Regular cleaning and maintenance can also help ensure optimal performance and longevity of the solar installation. Overall, Tumbes offers an ideal location for solar energy production, with its consistent year-round sunlight and minimal seasonal variations. By addressing the few environmental challenges, solar installations in this area can provide a reliable and efficient source of renewable energy.

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 47 locations across Peru. 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 Tumbes

Seasonal solar PV output for Latitude: -3.5693, Longitude: -80.4389 (Tumbes, Peru), 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 3° North in Tumbes, Peru

To maximize your solar PV system's energy output in Tumbes, Peru (Lat/Long -3.5693, -80.4389) throughout the year, you should tilt your panels at an angle of 3° North 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 Tumbes, Peru

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 Tumbes, Peru. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 3° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
12° South in Summer	9° North in Autumn	19° North in Winter	3° 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 Tumbes, Peru

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 Tumbes, Peru.

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 Tumbes, Peru

The topography around Tumbes, Peru, located at approximately -3.5693 latitude and -80.4389 longitude, is characterized by a diverse landscape that transitions from coastal plains to mountainous terrain. Along the Pacific coast, the area features sandy beaches and low-lying coastal plains. These flat, open areas gradually give way to gently rolling hills as one moves inland. As you travel further east from the coast, the terrain becomes more varied and elevated. The landscape begins to rise into the foothills of the Andes Mountains, with increasingly steep slopes and rugged terrain. This transition creates a mix of valleys, hills, and small mountain ranges that dominate the eastern part of the Tumbes region. The Tumbes River, which flows from the Andes Mountains to the Pacific Ocean, has carved out a fertile valley that cuts through the landscape. This river valley provides a stark contrast to the surrounding drier areas, creating a green corridor amidst the more arid terrain.

Solar PV Potential

When considering areas nearby that would be most suited to large-scale solar PV installations, the coastal plains and gently rolling hills just inland from Tumbes offer promising potential. These areas benefit from several advantageous factors: Firstly, the coastal region experiences high levels of solar radiation throughout the year, thanks to its proximity to the equator and generally clear skies. This consistent sunshine is crucial for maximizing solar energy production. Secondly, the relatively flat terrain of the coastal plains provides ideal conditions for the installation of large solar arrays. These areas offer ample space for expansive solar farms without the need for significant land preparation or the challenges associated with steep slopes. The gently rolling hills slightly inland from the coast could also be suitable for solar PV installations. These areas may provide good exposure to sunlight while potentially offering some natural protection from coastal winds and salt spray, which can be detrimental to solar equipment over time. It's important to note that while the mountainous regions to the east receive plenty of sunlight, their steep and rugged terrain makes them less ideal for large-scale solar installations due to the increased complexity and cost of construction in such areas. When planning solar PV projects, developers would need to consider factors such as proximity to existing power infrastructure, environmental impact, and local land use regulations. The areas closest to Tumbes city might offer advantages in terms of grid connection, but may also face more competition for land use. In conclusion, the flat coastal plains and gentle hills near Tumbes present the most promising areas for large-scale solar PV development, combining favorable topography with excellent solar resources.
