Solar PV Analysis of Oaxaca City, Mexico
Oaxaca City, Mexico is in a very good location for producing solar energy all year round. This city is located in the Tropics where sunlight is pretty much consistent throughout most of the year. The seasons here are often characterized by wet and dry periods rather than large changes in temperature.
The amount of electricity that can be produced from each kilowatt of installed solar panels varies slightly with the seasons. During summer, you can expect about 5.55 kilowatt-hours (kWh) per day for each kilowatt (kW) of installed solar panels. In autumn, this drops slightly to around 5.09 kWh/day per kW; in winter it's about 5.21 kWh/day per kW; and spring brings the highest production at approximately 6.47 kWh/day per kW.
Therefore, spring seems to be the ideal time for generating solar power at this location due to higher daily output but overall Oaxaca City has solid potential for year-round solar energy generation.
When installing fixed panel installations here, tilting them at an angle of 16 degrees towards South would maximize total yearly production from these panels.
However, there might be some local factors that could affect how much energy your solar panels produce like weather conditions or environmental factors specific to Oaxaca City - although without more detailed information it's hard to specify what these might be exactly.
For instance, heavy rainfall during the wet season may temporarily reduce output due to cloud cover but as long as enough light gets through on average over time then it shouldn't have too big an impact on overall annual production levels.
To ensure greater energy production despite these potential challenges when installing your system:
1) Make sure your installation site is free from shade especially during peak sunlight hours.
2) Regular maintenance including cleaning should be done since dust or debris can block sunlight.
3) If possible install a system that allows you adjust tilt angles based on the time of year to maximize exposure.
4) Use high-quality solar panels and inverters that can withstand local weather conditions.
In conclusion, Oaxaca City is a great place for solar panel installation due to its consistent sunlight throughout the year. By taking into account seasonal variations and maintaining your system properly, you can ensure optimal energy production from your solar panels.
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 358 locations across Mexico. 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 Oaxaca City
Seasonal solar PV output for Latitude: 17.1062, Longitude: -96.7203 (Oaxaca City, Mexico), 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 16° South in Oaxaca City, Mexico
To maximize your solar PV system's energy output in Oaxaca City, Mexico (Lat/Long 17.1062, -96.7203) throughout the year, you should tilt your panels at an angle of 16° South 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 Oaxaca City, Mexico
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 Oaxaca City, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 16° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 1° South in Summer | 23° South in Autumn | 32° South in Winter | 11° 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 Oaxaca City, Mexico
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 Oaxaca City, Mexico.
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 Oaxaca City, Mexico
Oaxaca City, Mexico is located in the southern part of the country and is surrounded by rugged mountains. The terrain varies from high plateaus to deep valleys, with a mix of forested areas and agricultural lands. The city itself lies in a valley known as the Valley of Oaxaca.
The climate in Oaxaca City is subtropical, characterized by warm temperatures throughout the year and significant rainfall during summer months. Despite this rainfall, it also receives plenty of sunshine making it suitable for solar power generation.
For large-scale solar PV installations, flat or gently sloping terrains are usually preferred to reduce installation costs and maximize efficiency. Considering this:
1) Plateau Areas: Some plateau regions around Oaxaca could potentially be suitable for large-scale solar PV installations if they are not heavily forested or used for agriculture.
2) Agricultural Lands: If farmers are willing to integrate solar panels into their fields (agrophotovoltaics), then agricultural lands around Oaxaca City could also be potential sites.
3) Desert Areas: Deserts receive abundant sunlight and have sparse vegetation which makes them ideal locations for large scale solar farms. However, there aren't desert landscapes very close to Oaxaca city but further out towards North-East Mexico.
4) Rooftop Solar: In urban areas like within Oaxaca City itself, rooftop solar can be an effective way to generate electricity without requiring additional land resources.
Before any definitive conclusions can be drawn about specific locations' suitability for large-scale solar PV installations near Oaxaca City, detailed feasibility studies would need to be conducted considering factors such as local weather patterns (including cloud cover), land ownership status and use restrictions.
