Solar PV Analysis of Cuernavaca, Mexico
Cuernavaca, Morelos, Mexico is a very good location for generating energy from solar panels all year round. This is because it's located in the Tropics where sunlight is consistent throughout most of the year. The seasons are more about wet and dry periods rather than large changes in temperature or sunlight.
In terms of how much electricity you can expect to generate from each kilowatt (kW) of solar power installed, here are some numbers: In summer you can expect around 6.52 kilowatt-hours (kWh) per day, 6.07 kWh/day in autumn, 6.02 kWh/day in winter and 7.65 kWh/day in spring.
The best time to generate solar power at this location would be during spring as this season has the highest average daily output.
For a fixed panel installation at this location, tilting the panels at an angle of 18 degrees towards south would give maximum production over the entire year.
However, there could be some local factors that might affect solar production:
1) During rainy season: Solar panels work by absorbing light from the sun - so during heavy rain or cloudy weather their efficiency decreases slightly as less sunlight reaches them.
2) Dust and dirt on panels: They can reduce efficiency if not cleaned regularly.
3) Shading issues: If there are tall buildings or trees nearby that cast shadows on your panels for part of the day they will produce less electricity during those times.
To ensure greater energy production despite these possible obstacles:
1) Install your system where it won't be shaded by nearby structures or vegetation.
2) Clean your panels regularly to remove dust and dirt.
3)
If heavy rainfall is common during certain times of year consider using a system with batteries so you can store excess power generated on sunny days for use when conditions aren't as ideal.
Overall though Cuernavaca seems like an excellent place for generating solar power throughout most 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 Cuernavaca
Seasonal solar PV output for Latitude: 18.9172, Longitude: -99.2143 (Cuernavaca, 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 Cuernavaca, Mexico
To maximize your solar PV system's energy output in Cuernavaca, Mexico (Lat/Long 18.9172, -99.2143) 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 Cuernavaca, 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 Cuernavaca, 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 Cuernavaca, 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 Cuernavaca, 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 Cuernavaca, Mexico
Cuernavaca, Mexico is located in the South-Central part of the country, within Morelos state. The city sits at an elevation of around 1,500 meters (4,921 feet) above sea level. The topography around Cuernavaca is diverse with mountainous terrain to the north and west and more flatlands to the south and east. This area is characterized by hills with steep slopes and valleys.
The region has a tropical savanna climate with a wet season in summer and a dry season in winter. It receives abundant sunlight throughout most of the year making it suitable for solar energy production.
In terms of large-scale solar PV installations, flatter areas would typically be more suitable as they require less site preparation work compared to hilly or mountainous terrains. Therefore, regions towards the south and east of Cuernavaca could potentially be more suited for such projects.
However, it's also important to consider other factors like local land use regulations, proximity to power grids for energy transmission, availability of water resources if needed for panel cleaning or cooling systems etc., before deciding on a location for large-scale solar PV projects.
Moreover nowadays technology allows installation even on uneven terrains using different types mounting structures that can adapt to irregular topographies but this might increase costs due its complexity.
Lastly it’s recommended that detailed feasibility studies including irradiance assessment (amount of sun hours), grid connection possibilities among others should be conducted before any final decision about where exactly establish these kind panels are taken.
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.
