The location at Saltillo, Coahuila, Mexico is quite suitable for generating energy through solar PV all year round. This region receives a good amount of sunlight throughout the year due to its position in the Northern Sub Tropics. The daily electricity output varies depending on the season, with summer and spring producing slightly more energy (7.11kWh/day and 7.61kWh/day respectively) than autumn and winter (5.83kWh/day and 5.21 kWh/day respectively). This means that although you can generate solar power throughout the year, spring and summer are particularly ideal times for this.
In terms of setting up your solar panels, it's best to tilt them 23 degrees towards the south to get maximum sunlight exposure over the course of a year.
However, there could be some local factors that might hinder optimal solar production such as dust storms or heavy rainfall which are common in this area during certain periods of the year. These can reduce sunlight reaching your panels thereby reducing their efficiency.
To mitigate these issues, regular maintenance like cleaning off dust or debris from your panels can help ensure they're working at their best capacity most of the time. Also consider installing protective measures like sturdy panel frames that can withstand strong winds during stormy weather conditions.
In conclusion, while Saltillo does present some challenges for solar production due to environmental factors like dust storms or rainfalls; with proper installation techniques and regular maintenance you should still be able to generate a substantial amount of energy via solar PV all through out each season.
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.
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 Saltillo
Seasonal solar PV output for Latitude: 25.0291, Longitude: -101.1251 (Saltillo, 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 23° South in Saltillo, Mexico
To maximize your solar PV system's energy output in Saltillo, Mexico (Lat/Long 25.0291, -101.1251) throughout the year, you should tilt your panels at an angle of 23° 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 Saltillo, 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 Saltillo, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 23° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 9° South in Summer | 30° South in Autumn | 40° South in Winter | 18° 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 Saltillo, 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 Saltillo, 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 Saltillo, Mexico
Saltillo, the capital of the state of Coahuila in Mexico, is situated in a high-altitude valley surrounded by mountains. The city sits at an elevation of approximately 1,600 meters (5,250 feet) above sea level. The terrain around Saltillo is mainly characterized by semi-arid conditions and mountainous landscapes.
The area to the east and south-east of Saltillo is relatively flat compared to other surrounding areas. This could potentially be suitable for large-scale installations due to its lower slope gradient and less shadowing from nearby mountains.
However, feasibility would also depend on other factors like land use restrictions or protections (e.g., agricultural or conservation lands), proximity to transmission lines or substations for grid connection, local regulations regarding projects etc., which need further detailed study on-site.
Additionally, considering that this region can experience dust storms that may affect efficiency and require regular maintenance; technology such as tracking systems could prove beneficial here.
Mexico solar PV Stats as a country
Mexico ranks 18th in the world for cumulative solar PV capacity, with 7,040 total MW's of solar PV installed. This means that 3.20% of Mexico's total energy as a country comes from solar PV (that's 28th in the world). Each year Mexico is generating 55 Watts from solar PV per capita (Mexico ranks 50th in the world for solar PV Watts generated per capita). [source]
Are there incentives for businesses to install solar in Mexico?
Yes, there are several incentives for businesses wanting to install solar energy in Mexico. The Mexican government offers a range of financial incentives and tax breaks for businesses that invest in renewable energy projects. These include grants, loans, and subsidies for the purchase of equipment and installation costs. Additionally, businesses can benefit from net metering programs which allow them to sell excess electricity back to the grid at a premium rate. Finally, businesses may also be eligible for additional benefits such as reduced import duties on solar equipment or accelerated depreciation allowances on investments in renewable energy projects.
