Solar PV Analysis of Hermosillo, Mexico
Hermosillo, Sonora, Mexico is generally a good location for solar energy production all year round due to its location in the Northern Sub Tropics. The amount of energy that can be produced from solar panels, measured in kilowatt-hours per day (kWh/day), varies depending on the season.
During summer, you can expect to generate about 7.60 kWh/day for each kilowatt of installed solar power. In autumn, this decreases slightly to around 5.82 kWh/day but drops further during winter with an average of 4.64 kWh/day. Come springtime, energy production picks up again and reaches its peak at approximately 8.25 kWh/day.
The ideal time for generating solar energy in Hermosillo would be during spring when sunlight availability is at its highest followed by summer.
For a fixed panel installation at this location, tilting the panels at an angle of 26 degrees towards the South will maximize total yearly production from your solar photovoltaic (PV) system.
As with any location, there could be local factors that may affect solar production such as weather conditions or topography features like mountains or buildings that could block sunlight reaching the panels.
In Hermosillo’s case, it's important to consider that while it has high sun exposure overall which is great for generating power via solar PVs; it also experiences some extreme heat and occasional dust storms which could potentially decrease efficiency and lifespan of your PV system if not properly managed.
To combat these challenges:
1) Regular cleaning and maintenance are essential especially after dust storms to ensure maximum sunlight absorption.
2) Using high-quality PV modules designed to withstand higher temperatures can help maintain efficiency even under intense heat.
3) Consider installing a cooling system or ensuring adequate ventilation around your PV modules as overheating can reduce their effectiveness over time.
4) If possible try positioning your panels where they won't be blocked by shadows from nearby structures or geographical features.
In conclusion, Hermosillo is a great place for solar energy production but like with any location, it's important to consider and manage local environmental factors to ensure the highest possible energy output from your solar PV system.
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 Hermosillo
Seasonal solar PV output for Latitude: 29.053, Longitude: -110.9153 (Hermosillo, 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 26° South in Hermosillo, Mexico
To maximize your solar PV system's energy output in Hermosillo, Mexico (Lat/Long 29.053, -110.9153) throughout the year, you should tilt your panels at an angle of 26° 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 Hermosillo, 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 Hermosillo, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 26° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 13° South in Summer | 34° South in Autumn | 44° South in Winter | 22° 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 Hermosillo, 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 Hermosillo, 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 Hermosillo, Mexico
Hermosillo is located in the Sonoran Desert, which is known for its hot and arid climate. The topography around Hermosillo consists of flat plains and low hills, with a few mountain ranges to the west. The region is mostly desert scrubland, with sparse vegetation adapted to the harsh desert conditions.
Considering this topography and climatic conditions, large-scale solar PV projects would be well suited for the flat plains surrounding Hermosillo. These areas receive abundant sunlight throughout the year, making them ideal for capturing solar energy. Additionally, their relative lack of vegetation minimizes any potential environmental impact from installing solar panels.
However, it's important to consider other factors such as accessibility for construction and maintenance crews or proximity to existing power grids when choosing a location for large-scale solar PV projects.
For instance:
1) El Desemboque area (located at 30°32'48"N 112°23'24"W), which lies on flat coastal plains northwest of Hermosillo.
2) Areas south-east towards Estación Zamora (28°38'56"N 110°34'23"W), where there are vast expanses of relatively flat land.
These areas could potentially be suitable sites due to their geographical features but these decisions should also take into account socio-economic factors like local land use practices or potential conflicts with indigenous communities’ rights over lands etc.
It's always recommended that thorough feasibility studies are conducted before deciding on a location for such large-scale projects.
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.
