Solar PV Analysis of Tlaxcala City, Mexico
Tlaxcala City, Mexico is a good location for generating electricity through solar panels all year round. This is because it's located in the Tropics where sunlight is pretty consistent throughout most of the year. The city experiences more wet and dry seasons rather than the four seasons we typically think of.
The amount of electricity you can get from each kilowatt (kW) of solar power installed varies slightly by season. In summer, autumn, and winter you can expect around 5.8 to 5.9 kilowatt-hours (kWh) per day per kW installed, while in spring you could get up to 7.23 kWh/day per kW installed.
Spring seems to be the best time for generating solar energy at this location due to higher daily output levels compared with other seasons.
If you're installing fixed panel solar power systems here, tilting them at an angle of 19 degrees towards South would give maximum production throughout the year.
There may be certain local factors that could hinder solar production in Tlaxcala City though not significantly. These might include weather conditions like cloud cover or dust storms which can block sunlight hence reducing efficiency of your panels; also high temperatures might overheat panels and reduce their effectiveness too.
To overcome these challenges when installing your system:
- You could consider using advanced PV modules designed to perform well under high temperatures.
- Regular cleaning/maintenance will keep your panels free from dust or dirt that could block sunlight.
- If cloud cover is frequent during certain times/seasons then having battery storage system could help store excess energy produced during sunny periods and use it when needed.
Overall though, this location has great potential for harnessing solar energy effectively all year round given its position within the tropics and consistent sunshine exposure throughout most parts of the year.
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 Tlaxcala City
Seasonal solar PV output for Latitude: 19.3229, Longitude: -98.2 (Tlaxcala 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 19° South in Tlaxcala City, Mexico
To maximize your solar PV system's energy output in Tlaxcala City, Mexico (Lat/Long 19.3229, -98.2) throughout the year, you should tilt your panels at an angle of 19° 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 Tlaxcala 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 Tlaxcala City, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 19° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 4° South in Summer | 26° South in Autumn | 35° South in Winter | 13° 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 Tlaxcala 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 Tlaxcala 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 Tlaxcala City, Mexico
Tlaxcala City is located in the Central-Eastern region of Mexico. The topography of this area is characterized by a mix of highlands, valleys, and mountains due to its location on the Trans-Mexican Volcanic Belt. The city itself sits at an elevation of about 2,230 meters above sea level.
As for solar PV potential, areas with flat or gently sloping terrains would be most suited for large-scale solar photovoltaic installations. Considering Tlaxcala's topography, the valleys around the city might be suitable locations for such projects.
Also important to consider are factors such as local climate (solar irradiance), land use restrictions, proximity to transmission lines or grids and accessibility for construction and maintenance work.
The state of Tlaxcala has a temperate sub-humid climate with summer rains which means it receives ample sunshine throughout most parts of the year making it potentially suitable for solar power generation.
However, any specific site selection would require detailed feasibility studies including technical aspects like insolation levels (amount of solar radiation reaching the ground), soil type etc., environmental considerations as well as socio-economic factors.
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.
