The location at Tenancingo de Degollado, Mexico is quite suitable for year-round solar energy generation. This area, located in the Tropics, enjoys consistent sunlight throughout most of the year. The seasons here are usually characterized more by wet and dry periods rather than drastic changes in temperature or sunlight.
Based on the electricity output you've provided per season (Summer: 6.52kWh/day, Autumn: 6.07kWh/day, Winter: 6.02kWh/day and Spring: 7.65kWh/day), it's clear that there is a steady production of solar energy across all seasons with a small peak during springtime.
To maximize total solar power production throughout the year at this location, it's recommended to tilt your fixed panel installations towards an angle of 18 degrees South; this position will optimize exposure to sunlight over the course of each day and each season.
However, there could be some potential local factors that might affect solar production at this location:
1) Rainy Season - In tropical regions like Tenancingo de Degollado, heavy rain during certain parts of the year can reduce sunlight exposure and therefore decrease your PV system's efficiency temporarily.
2) Dust & Dirt - If dust or dirt accumulates on your panels' surfaces over time (especially during dry seasons), they may block some incoming light which can lower overall system performance.
To counter these issues:
- It would be beneficial to monitor weather patterns closely so you're aware when heavier rainfall periods are approaching; during these times extra measures could be taken such as installing protective coverings or adjusting panel angles if possible.
- Regular cleaning maintenance should also be scheduled for your panels particularly before/during dry seasons when dust levels may increase; ensuring they remain clean will help maintain their maximum efficiency level consistently throughout each year.
In conclusion though despite these potential challenges with proper planning and maintenance efforts Tenancingo de Degollado is a very good location for consistent year-round solar energy generation.
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 Tenancingo De Degollado
Seasonal solar PV output for Latitude: 18.9628, Longitude: -99.5856 (Tenancingo De Degollado, 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 18° South in Tenancingo De Degollado, Mexico
To maximize your solar PV system's energy output in Tenancingo De Degollado, Mexico (Lat/Long 18.9628, -99.5856) throughout the year, you should tilt your panels at an angle of 18° 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 Tenancingo De Degollado, 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 Tenancingo De Degollado, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 18° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 3° South in Summer | 25° South in Autumn | 34° 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 Tenancingo De Degollado, 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 Tenancingo De Degollado, 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 Tenancingo De Degollado, Mexico
Tenancingo de Degollado is located in the State of Mexico, central Mexico. The topography around this area is characterized by a mix of mountains, valleys, and plains. It's situated in the southern part of the Mexican Plateau but also close to the Sierra Madre del Sur mountain range.
Given its geographical location and climate (subtropical highland climate), it receives significant amounts of sunlight throughout the year, making it suitable for solar PV installations. However, flat areas would be more appropriate for large-scale solar farms due to easier installation and maintenance.
The plains surrounding Tenancingo de Degollado would be ideal for large-scale solar PV systems as they offer expansive flat land with great exposure to sunlight. Areas towards the north and northeast are relatively flatter compared to those south which are more mountainous.
However, a detailed site assessment considering factors such as land ownership status, proximity to transmission lines or substations (for grid connectivity), environmental impact assessments etc., would still need to be conducted before deciding on a specific site for setting up a large-scale solar PV system.
It's also worth noting that while flat terrain is generally preferred for ease of installation and maintenance, hilly or mountainous terrain can still host solar panels if designed correctly - although at potentially higher costs due to increased complexity in construction and operation processes.
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.
