Chone, Manabí, Ecuador presents a favorable location for year-round solar energy generation, with the tropical climate providing consistent sunlight throughout most of the year. Located near the equator at coordinates -0.699, -80.0966, this region experiences relatively stable solar production across all seasons.

Seasonal Solar Production Performance

The solar energy output at Chone shows moderate seasonal variation, with autumn delivering the highest production at 5.07kWh per day per kW of installed solar capacity. Summer follows closely with 4.66kWh/day per kW, while winter and spring both produce around 4.00-4.01kWh/day per kW. Autumn emerges as the ideal time for solar generation at this location, likely coinciding with clearer skies and optimal atmospheric conditions. The relatively modest difference between peak and lowest production seasons (about 25% variation) demonstrates the location's reliability for consistent solar energy throughout the year. For maximum efficiency, solar panels should be installed at a fixed tilt angle of 1 degree North, which optimizes total year-round energy production by accounting for the sun's path and seasonal variations at this near-equatorial location.

Environmental and Weather Challenges

Several significant factors could impact solar production in Chone's tropical environment:

• Heavy rainfall during wet seasons can reduce solar irradiance and create temporary production drops
• High humidity levels may cause condensation on panel surfaces, reducing efficiency
• Frequent cloud cover during rainy periods can significantly decrease energy output
• Dust and debris accumulation from tropical vegetation and occasional dust storms
• Potential for extreme weather events including tropical storms or heavy winds

Preventative Installation Measures

To maximize solar energy production despite these challenges, several installation strategies prove effective. Proper drainage systems around solar arrays prevent water pooling and ensure quick runoff during heavy rains. Installing panels with adequate spacing allows for better air circulation, reducing humidity-related condensation issues. Regular cleaning schedules become essential in this environment, with automated cleaning systems or easy-access designs facilitating maintenance. Choosing panels with anti-reflective coatings and hydrophobic surfaces helps shed water and reduce soiling effects. Robust mounting systems designed for high wind loads protect against storm damage, while strategic positioning away from large trees reduces debris accumulation. Installing monitoring systems helps identify production drops quickly, enabling prompt maintenance responses to weather-related issues.

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 Chone

Seasonal solar PV output for Latitude: -0.699, Longitude: -80.0966 (Chone, 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 Chone, Ecuador

To maximize your solar PV system's energy output in Chone, Ecuador (Lat/Long -0.699, -80.0966) 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 Chone, 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 Chone, 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
15° South in Summer	6° 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 Chone, 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 Chone, 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 Chone, Ecuador

Topographical Features Around Chone

Chone sits in the coastal lowlands of Ecuador's Manabí Province, positioned within a relatively flat river valley that extends inland from the Pacific coast. The terrain around this agricultural hub is characterized by gently rolling hills and fertile alluvial plains that have been shaped by the Chone River and its tributaries over millennia. The elevation in the immediate vicinity ranges from approximately 20 to 100 meters above sea level, creating a landscape that transitions gradually from the river floodplains to slightly elevated ridges.

The topography becomes more pronounced as one moves away from the central valley. To the east and southeast, the land begins to rise more noticeably toward the foothills of the Coastal Range, where elevations can reach several hundred meters. These areas feature steeper slopes and more dissected terrain, with numerous small valleys carved by seasonal streams. To the west, the land remains relatively flat as it approaches the coastal plain, maintaining the gentle character typical of Ecuador's western lowlands.

The river systems in the region have created a network of fertile valleys separated by low ridges and terraces. These elevated areas between waterways often provide stable, well-drained ground that contrasts with the occasionally flood-prone areas closer to the main river channels. The overall landscape reflects the influence of both fluvial processes and the region's position within the broader geological framework of Ecuador's coastal zone.

Optimal Areas for Large-Scale Solar Development

The elevated terraces and gentle ridges surrounding the Chone River valley present the most promising locations for large-scale solar photovoltaic installations. These areas offer several advantages, including stable ground conditions, minimal flood risk, and relatively easy access for construction and maintenance activities. The slightly elevated terrain also provides natural drainage, reducing concerns about water accumulation during the rainy season.

Areas to the northeast and southeast of Chone, where the land begins to rise toward the Coastal Range foothills, are particularly well-suited for solar development. These locations combine the benefits of elevation with manageable slopes that don't require extensive grading or specialized mounting systems. The terrain in these areas typically features broad, gently sloping surfaces that can accommodate large arrays while maintaining reasonable construction costs.

The western approaches toward the coast also offer suitable terrain, particularly on the slightly elevated ground between river valleys. These areas tend to have consistent topography over large expanses, making them ideal for utility-scale installations. The relatively flat nature of this terrain minimizes shading issues between panel rows and allows for efficient land use patterns.

Areas immediately adjacent to the river channels and in the lowest portions of the valley floor would be less suitable due to periodic flooding and potentially unstable soil conditions. Similarly, the steeper slopes found in the more elevated eastern areas would present engineering challenges and higher development costs, making them less attractive for large-scale projects despite their elevation advantages.
