Pasaje, Ecuador presents an excellent location for year-round solar energy generation, with consistently strong performance across all seasons due to its tropical location near the equator.

Solar Energy Performance

The solar energy output at this location remains remarkably stable throughout the year. Spring delivers the highest production at 4.39 kWh per day per kW of installed solar capacity, closely followed by autumn at 4.37 kWh per day. Summer provides solid output at 4.03 kWh per day, while winter shows the lowest but still respectable production at 3.78 kWh per day. This consistency makes Pasaje an ideal location for solar installations, as energy production remains reliable regardless of the season. The variation between the best and worst performing seasons is only about 16%, which is exceptionally low compared to locations further from the equator.

Optimal Panel Installation

For maximum year-round energy production, solar panels should be installed at a fixed tilt angle of 1 degree facing north. This nearly flat installation angle reflects the location's proximity to the equator, where the sun passes almost directly overhead throughout the year.

Environmental and Weather Considerations

Several local factors could potentially impact solar energy production at this location:

• High humidity and frequent cloud cover during wet seasons - Ecuador's tropical climate brings periods of heavy cloud coverage that can reduce solar irradiance
• Dust and debris accumulation - The combination of dry periods followed by heavy rains can leave residue on panels
• Intense UV exposure - Being near the equator means extremely strong solar radiation that can degrade equipment faster
• Heavy rainfall - Torrential tropical downpours during wet seasons can affect system components

Preventative Measures

To maximize energy production and system longevity, several installation strategies should be considered. Using high-quality panels with superior low-light performance helps maintain output during cloudy periods. Installing panels with adequate spacing and ventilation prevents overheating in the intense equatorial sun. Regular cleaning schedules become essential, particularly after dust storms or heavy rains. Automated cleaning systems or easily accessible panel layouts facilitate maintenance. Choosing inverters and electrical components rated for high humidity and temperature extremes ensures reliable operation. Proper drainage around ground-mounted systems prevents water damage during heavy rainfall periods. Additionally, selecting panels and mounting systems with enhanced UV resistance helps combat the intense solar radiation that could otherwise cause premature degradation of system components.

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 Pasaje, Guayas

Seasonal solar PV output for Latitude: -1.1819, Longitude: -79.9199 (Pasaje, Guayas, Ecuador), 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 1° North in Pasaje, Guayas, Ecuador

To maximize your solar PV system's energy output in Pasaje, Guayas, Ecuador (Lat/Long -1.1819, -79.9199) throughout the year, you should tilt your panels at an angle of 1° 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 Pasaje, Guayas, Ecuador

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 Pasaje, Guayas, Ecuador. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 1° North tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
14° South in Summer	7° North in Autumn	17° North in Winter	5° 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 Pasaje, Guayas, Ecuador

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 Pasaje, Guayas, Ecuador.

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 Pasaje, Guayas, Ecuador

Topographical Features Around Pasaje

Pasaje sits in the coastal lowlands of southwestern Ecuador, positioned within El Oro Province near the border with Peru. The terrain around this area is characterized by relatively flat to gently rolling plains that gradually transition from the Pacific coastal region toward the foothills of the Andes Mountains to the east. The elevation in and around Pasaje remains quite modest, typically ranging from sea level along the coast to several hundred meters above sea level as the landscape begins its ascent toward the mountain ranges.

The topography is dominated by alluvial plains formed by river systems that flow westward from the Andes toward the Pacific Ocean. These plains are intersected by numerous waterways, including tributaries and seasonal streams that create a network of valleys and slightly elevated ridges. The terrain is generally well-drained, though some areas experience seasonal flooding during the rainy periods.

Moving eastward from Pasaje, the landscape begins to show more pronounced elevation changes as it approaches the western slopes of the Andes. However, the immediate vicinity remains relatively flat with gentle undulations that rarely present significant topographical obstacles. The coastal influence keeps much of the surrounding area at low elevations with gradual slopes that are well-suited to various land uses.

Optimal Areas for Large-Scale Solar Development

The flat to gently rolling terrain surrounding Pasaje presents excellent opportunities for large-scale solar photovoltaic installations. The most suitable areas would be the expansive alluvial plains that extend both north and south of the town, where minimal grading would be required to establish solar arrays. These areas offer the advantage of relatively uniform topography with gentle slopes that facilitate proper drainage while maintaining optimal panel positioning.

The agricultural lands on the broader plains would be particularly well-suited for solar development, as they typically feature open spaces with minimal existing infrastructure that could create shading issues. Areas slightly elevated above the immediate floodplains would be preferable to avoid potential water-related complications during wet seasons, while still maintaining the flat characteristics ideal for solar panel installation.

The terrain to the northeast and northwest of Pasaje appears most promising for large installations, where the topography remains consistently gentle but provides sufficient elevation to ensure good drainage. These areas would allow for extensive solar farms with minimal earthwork requirements, reducing installation costs and environmental impact. The relatively stable geological conditions of the alluvial plains also provide solid foundations for mounting systems.

Areas closer to the eastern foothills should generally be avoided for large-scale projects due to increasing terrain complexity and potential shading from elevated landforms. Similarly, locations too close to major waterways might present seasonal accessibility challenges, making the intermediate elevations between the river valleys and the steeper terrain the most practical choice for substantial solar installations.
