Guayaquil, Provincia del Guayas, Ecuador (latitude -2.1962, longitude -79.8862) is a suitable location for solar photovoltaic (PV) generation due to its relatively consistent sunlight exposure throughout the year. The average energy production per day per kW of installed solar in each season is as follows: 4.21 kWh in Summer, 4.32 kWh in Autumn, 3.84 kWh in Winter, and 4.46 kWh in Spring.
For a fixed panel installation at this location, the ideal angle to tilt panels is 2 degrees North to maximize solar energy capture and generation efficiency.
While Guayaquil's overall sunlight availability is favorable for solar power generation year-round, local factors such as heavy rain or cloud cover can sometimes reduce the amount of power generated from solar PV systems. To help ensure greater energy production despite these weather conditions, it may be beneficial to install panels with a higher efficiency rating or incorporate technologies that optimize power output under variable light conditions during the installation process.
In conclusion, Guayaquil offers an advantageous environment for generating solar power throughout the year; however, it's essential to consider potential weather-related challenges when designing and installing a system at this location.
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 Guayaquil
Seasonal solar PV output for Latitude: -2.1962, Longitude: -79.8862 (Guayaquil, 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 2° North in Guayaquil, Ecuador
To maximize your solar PV system's energy output in Guayaquil, Ecuador (Lat/Long -2.1962, -79.8862) throughout the year, you should tilt your panels at an angle of 2° 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 Guayaquil, 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 Guayaquil, Ecuador. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 2° North tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° South in Summer | 8° North in Autumn | 18° North in Winter | 4° 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 Guayaquil, 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 Guayaquil, 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 Guayaquil, Ecuador
The topography of the area around Guayaquil, Ecuador is fairly flat and low-lying. The coastal areas are mostly plains with some hills and mountains in the more inland regions. Areas that would be most suitable for large-scale solar PV installations would be those with unobstructed access to direct sunlight, such as open fields or rooftops. Clearings in forests or other vegetation could also potentially be used for this purpose.
