Manta, Manabí, Ecuador, situated at -0.9444 latitude and -80.7356 longitude, presents a generally favorable location for solar energy production throughout the year. This tropical coastal city experiences consistent sunlight, with seasons characterized more by wet and dry periods rather than traditional temperature-based seasons.

Seasonal Solar Performance

Solar panel efficiency in Manta varies slightly across the meteorological seasons. Autumn proves to be the most productive period, generating an average of 5.04 kWh per day for each kilowatt of installed solar capacity. Summer follows closely behind with 4.65 kWh/day. Winter and spring show slightly lower but still substantial outputs at 4.00 kWh/day and 3.99 kWh/day, respectively. These figures indicate that Manta maintains relatively stable solar energy production throughout the year, with only minor fluctuations between seasons. This consistency is a significant advantage for solar power systems, as it allows for more reliable energy forecasting and reduces the need for supplementary power sources during less productive periods.

Optimal Panel Positioning

For fixed solar panel installations in Manta, Manabí, the ideal tilt angle to maximize year-round energy production is 1 degree North. This nearly flat orientation takes advantage of the city's proximity to the equator, where the sun's path remains relatively high in the sky throughout the year. This optimal angle ensures that panels capture the maximum amount of sunlight across all seasons, contributing to the location's overall suitability for solar energy generation.

Environmental Considerations

While Manta's climate is generally conducive to solar energy production, there are some environmental factors to consider: 1. Coastal humidity: Manta's location on the Pacific coast means high humidity levels, which can potentially lead to accelerated corrosion of solar equipment. 2. Salt spray: Being close to the ocean, salt spray can accumulate on solar panels, potentially reducing their efficiency over time. To mitigate these issues, installers should use corrosion-resistant materials and apply protective coatings to solar panels and supporting structures. Regular cleaning and maintenance of the panels will also help maintain optimal performance. Additionally, installing panels at a slight angle (as recommended) can aid in natural cleaning during rainfalls. In conclusion, Manta, Manabí, Ecuador offers an excellent location for year-round solar energy production. Its consistent sunlight and minimal seasonal variations in solar output make it an ideal candidate for solar PV installations. With proper planning and maintenance to address the minor environmental challenges, solar energy systems in Manta can provide reliable and efficient renewable energy throughout the year.

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

Seasonal solar PV output for Latitude: -0.9444, Longitude: -80.7356 (Manta, 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 Manta, Ecuador

To maximize your solar PV system's energy output in Manta, Ecuador (Lat/Long -0.9444, -80.7356) 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 Manta, 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 Manta, 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 Manta, 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 Manta, 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 Manta, Ecuador

The topography around Manta, Ecuador is characterized by a diverse landscape that transitions from coastal plains to rolling hills and eventually to more mountainous terrain as you move inland. Manta itself is situated on the Pacific coast, with relatively flat terrain near the shoreline. The city is built on a small peninsula that juts out into the ocean, providing natural protection for its port. As you move away from the coast, the land gradually rises, forming low hills and plateaus. These areas are often covered in dry tropical forest and scrubland vegetation, typical of the region's climate. The terrain becomes increasingly undulating, with shallow valleys and ridges creating a gently rolling landscape. Further inland, about 30-40 kilometers from the coast, the topography becomes more pronounced. Here, the foothills of the Andes Mountains begin to emerge, with steeper slopes and higher elevations. This area marks the transition between the coastal lowlands and the more mountainous interior of Ecuador.

Suitable Areas for Large-Scale Solar PV

When considering locations for large-scale solar photovoltaic (PV) installations near Manta, the most suitable areas would likely be found in the gently rolling terrain just inland from the coast. These areas offer several advantages for solar energy production: Firstly, the slightly elevated positions of these inland areas often receive more consistent sunlight throughout the day, with fewer obstructions from coastal fog or low-lying clouds that can sometimes affect the immediate coastline. Secondly, the undulating landscape provides opportunities to position solar panels on south-facing slopes (in the Southern Hemisphere), which can optimize their exposure to sunlight and increase energy production efficiency. The dry climate of this region is also beneficial for solar PV installations, as it means less rainfall and cloud cover, resulting in more days of clear, sunny weather. This climate contributes to higher overall energy production potential. Additionally, these inland areas often have less dense population and development compared to the coastal city, potentially offering larger tracts of available land for expansive solar farms. The proximity to Manta's urban center and port facilities could also be advantageous for energy distribution and equipment transportation. However, it's important to note that any large-scale solar project would require detailed site-specific assessments, including environmental impact studies and consideration of local ecosystems, particularly given the presence of dry tropical forests in the region.
