Solar PV Analysis of Guanajuato City, Mexico
Guanajuato City, Mexico is a pretty good spot for generating solar energy all year round because it's located in the Tropics where sunlight is quite consistent. The amount of electricity you can expect to produce from each kilowatt (kW) of solar panels installed changes slightly with the seasons. In summer, it's about 6.52 kilowatt-hours (kWh) per day, in fall it drops a bit to 5.75 kWh/day, then it goes up again slightly in winter to 6 kWh/day and reaches its highest point in spring at 8.01 kWh/day.
This means that while you'll get decent power generation throughout the year, spring would be the most productive season for your solar panels here due to increased sunlight hours and intensity.
To make sure you're getting as much power as possible from your panels throughout the year at this location, they should be set up at an angle facing 20 degrees South. This will help capture more sunlight overall.
As far as local factors that could reduce how much power you generate from your solar panels go – Guanajuato City does experience some rainy weather which could decrease production temporarily during those periods due to cloud cover blocking direct sunlight on panel surface area.
Also keep in mind that dust and dirt can accumulate on your solar panels over time which might block some light too if not cleaned regularly – especially during dry seasons when there’s less rainwater washing off any buildup naturally.
To prevent these issues affecting output too much:
1) Consider installing a system that automatically cleans or wipes down your panels periodically so they stay clear of dust and debris.
2) If heavy rainfall or storms are expected based on local weather forecasts - consider protective measures such as covers or shields to prevent potential damage.
3) Regular maintenance checkups by professionals can also ensure optimal performance by spotting any potential issues early before they become bigger problems later on like shading from nearby trees or buildings, bird droppings etc.
So overall, Guanajuato City is a pretty good spot for solar power generation throughout the year with just a few considerations to keep in mind for optimal production.
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 Guanajuato City
Seasonal solar PV output for Latitude: 21.0174, Longitude: -101.2428 (Guanajuato 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 20° South in Guanajuato City, Mexico
To maximize your solar PV system's energy output in Guanajuato City, Mexico (Lat/Long 21.0174, -101.2428) throughout the year, you should tilt your panels at an angle of 20° 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 Guanajuato 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 Guanajuato City, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 20° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 5° South in Summer | 27° South in Autumn | 36° South in Winter | 14° 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 Guanajuato 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 Guanajuato 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 Guanajuato City, Mexico
Guanajuato City, Mexico is located in a mountainous region. It is situated in a narrow valley, which makes the city have steep and irregular terrain with altitudes ranging between 1,996 to 2,600 meters above sea level. The city is surrounded by hills and mountains.
For large-scale solar PV installations, flat or gently sloping terrains are typically preferred because they require less site preparation work and are easier for installation of the panels. Therefore, the immediate surroundings of Guanajuato City may not be suitable for such projects due to its mountainous topography.
However, there are areas nearby that could potentially be suited for large-scale solar PV systems. These include:
1) Bajio Region: This region includes parts of Guanajuato state as well as portions of Queretaro, Jalisco and Michoacán states. It's characterized by its relatively flat terrain which would be ideal for installing solar panels.
2) Northern Plateau: North of Guanajuato lies Mexico's Northern Plateau (also known as Mexican Altiplano), which has vast areas with gentle slopes that might also accommodate large-scale solar farms.
3) Desert Areas: To the north and northwest from Guanajuato are semi-arid regions like Zacatecas and San Luis Potosi states where sunlight exposure is high making it suitable for solar energy generation.
It should also be noted that suitability doesn't only depend on topography but other factors including local climate conditions (amounts of sunlight), land use regulations, proximity to power transmission lines etc., must also be considered when planning for large scale Solar PV installations.
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.
