Ambato, Tungurahua Province, Ecuador, situated at latitude -1.2484 and longitude -78.6133, presents a favorable location for solar energy generation throughout the year. This tropical city experiences consistent sunlight, with seasonal variations primarily characterized by wet and dry periods rather than traditional temperature-based seasons.
Year-round Solar Potential
The solar energy output in Ambato remains relatively stable across all meteorological seasons. Spring stands out as the most productive period, with an average daily output of 4.65 kWh per kW of installed solar capacity. Summer and winter follow closely, generating 4.16 kWh/day and 4.09 kWh/day, respectively. Autumn sees a slight dip but still maintains a respectable 3.99 kWh/day. This consistency in solar production throughout the year makes Ambato an ideal location for solar PV installations. The minimal fluctuation between seasons ensures a reliable energy supply, reducing the need for extensive energy storage systems or supplementary power sources.Optimal Panel Tilt
For fixed solar panel installations in Ambato, Tungurahua Province, the ideal tilt angle to maximize year-round production is 1 degree North. This nearly horizontal orientation is due to the city's proximity to the equator, where the sun's path remains relatively overhead throughout the year.Environmental Considerations
While Ambato's location is generally favorable for solar energy production, there are a few environmental factors to consider: 1. Cloud cover: The region experiences a rainy season, typically from October to May, which may temporarily reduce solar efficiency. 2. Volcanic ash: Ambato's proximity to active volcanoes like Tungurahua could lead to occasional ash fall, potentially affecting panel performance. To mitigate these factors, consider the following preventative measures:- Install self-cleaning panels or implement regular cleaning schedules to combat ash accumulation.
- Use high-efficiency panels that perform well in diffuse light conditions during cloudy periods.
- Implement a robust monitoring system to quickly identify and address any performance issues.
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 108 locations across Ecuador. 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 Ambato
Seasonal solar PV output for Latitude: -1.2484, Longitude: -78.6133 (Ambato, 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 Ambato, Ecuador
To maximize your solar PV system's energy output in Ambato, Ecuador (Lat/Long -1.2484, -78.6133) 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 Ambato, 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 Ambato, 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 | 8° 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 Ambato, 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 Ambato, Ecuador.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 Ambato, Ecuador
The topography around Ambato, Ecuador, is characterized by its location in the Andean highlands, nestled within a valley surrounded by mountains. Situated at an elevation of approximately 2,600 meters (8,530 feet) above sea level, Ambato is part of the Inter-Andean valley system. The landscape is dominated by rolling hills, steep slopes, and volcanic features, as the city lies in the shadow of several active and dormant volcanoes. To the west of Ambato, the terrain becomes more rugged as it rises towards the Western Cordillera of the Andes. This area is marked by deep ravines, steep cliffs, and high-altitude páramo ecosystems. To the east, the land gradually descends towards the Amazon basin, with the Eastern Cordillera of the Andes presenting a barrier of high peaks and dense cloud forests. The Ambato River cuts through the city, carving a valley that provides some flatter areas amidst the otherwise hilly terrain. The surrounding landscape is a patchwork of agricultural fields, interspersed with patches of native vegetation and reforested areas.
Areas Suitable for Large-Scale Solar PV
When considering areas nearby Ambato for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would combine favorable topography, high solar radiation, and minimal environmental impact. The plains and gentler slopes to the south and southeast of Ambato present promising opportunities for solar PV development. These areas, extending towards the city of Riobamba, offer more expansive, flatter terrain that could accommodate large arrays of solar panels. The slightly lower elevation compared to Ambato itself may also provide more consistent weather conditions, with fewer clouds and fog that can sometimes affect higher altitudes. Another potential area lies to the northeast of Ambato, in the direction of Pillaro. This region features some highland plateaus that could be suitable for solar farms. The relatively open landscape in this direction receives good sun exposure throughout the year. It's important to note that while the immediate vicinity of Ambato is quite hilly and densely populated, moving just 20-30 kilometers out from the city center reveals more open spaces that could be adapted for solar energy production. These areas often have the added advantage of being close enough to existing power infrastructure to facilitate grid connection. However, any large-scale solar PV project in this region would need to carefully consider environmental impacts, especially given the sensitive nature of Andean ecosystems. Proper site selection would involve balancing energy production potential with conservation efforts and local land use needs.Citation Guide
