Delicias, Chihuahua, Mexico, situated in the Northern Sub Tropics at coordinates 28.191, -105.4737, offers a promising location for solar photovoltaic (PV) energy generation throughout the year. The solar electricity production varies across seasons but maintains relatively strong output year-round.

Seasonal Solar Production

Solar panels in Delicias demonstrate excellent performance across all seasons. Spring yields the highest daily production at 7.84 kWh per kilowatt installed, closely followed by summer with 7.62 kWh/day. Production decreases in autumn to 5.81 kWh/day and reaches its lowest in winter at 4.81 kWh/day per kilowatt installed.

The most productive period spans from March through September, with peak performance occurring during the spring months. Even during winter, when production is at its lowest, the output remains relatively substantial compared to many other locations globally.

Optimal Panel Installation

For fixed solar panel installations in Delicias, Chihuahua, the ideal tilt angle to maximize year-round energy production is 25 degrees facing South. This specific angle optimizes the capture of solar radiation throughout the year, taking into account the location's latitude and seasonal sun path variations.

Environmental Considerations

Delicias faces several environmental factors that could potentially impact solar production:

• Dust and dirt accumulation: The semi-arid climate can lead to dust buildup on panels, potentially reducing efficiency by 5-15% if not addressed.
• Occasional extreme heat: Summer temperatures can exceed 40°C (104°F), which may slightly reduce panel efficiency.
• Seasonal thunderstorms: During summer monsoon periods, brief but intense storms can temporarily reduce production.

Preventative Measures

To maximize solar production in Delicias, Chihuahua, several practical steps can be taken during installation and maintenance:

• Implement regular cleaning schedules, ideally every 2-3 months, using appropriate non-abrasive methods to remove dust accumulation.
• Install panels with sufficient elevation from the ground (minimum 1 meter) to reduce dust collection and allow for natural cleaning during rainfall.
• Select high-quality panels with good heat tolerance ratings, as these will maintain better efficiency during the hottest months.
• Consider a slight adjustment to the recommended tilt angle (perhaps 27-28 degrees) if dust is a major concern, as this can facilitate better self-cleaning during occasional rainfall.
• Install robust mounting systems that can withstand occasional strong winds during storm seasons.

With these considerations addressed, Delicias presents an excellent location for solar PV installation, with strong year-round production potential and manageable environmental challenges.

Solar output per kW of installed solar PV by season in Delicias

Seasonal solar PV output for Latitude: 28.191, Longitude: -105.4737 (Delicias, 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 25° South in Delicias, Mexico

To maximize your solar PV system's energy output in Delicias, Mexico (Lat/Long 28.191, -105.4737) throughout the year, you should tilt your panels at an angle of 25° 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 Delicias, 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 Delicias, Mexico. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 25° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
12° South in Summer	33° South in Autumn	43° South in Winter	21° 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 Delicias, 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 Delicias, Mexico.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Delicias, Mexico

The topography surrounding Delicias, Mexico presents a diverse landscape situated within the central part of the state of Chihuahua. Located at approximately 28.191°N and 105.4737°W, Delicias sits in a semi-arid region characterized by relatively flat terrain interspersed with gentle rolling hills. The city itself lies at an elevation of about 1,170 meters (3,840 feet) above sea level in the Conchos River Valley. The immediate surroundings of Delicias feature predominantly flat plains that were historically part of an extensive desert landscape. These plains extend outward from the city in multiple directions, creating wide open spaces with minimal topographical barriers. To the east and northeast, the terrain gradually rises toward the Sierra Madre Oriental mountain range, though these mountains are quite distant from Delicias itself.

Geographical Features

The Conchos River, a major tributary of the Rio Grande, flows near Delicias and has shaped much of the local topography through centuries of erosion and deposition. This waterway has created fertile valleys amid the otherwise arid landscape, supporting the agricultural activities for which the region is known. The broader region exhibits a basin and range topography typical of northern Mexico, with isolated mountain ranges separated by broad valleys and plains. While mountains are visible on the horizon from Delicias, the immediate vicinity is characterized by its relatively level terrain with gradual elevation changes.

Optimal Areas for Solar PV Development

The flat plains extending to the west and southwest of Delicias present particularly favorable conditions for large-scale solar photovoltaic installations. These areas combine several advantageous characteristics: minimal topographical variation, limited vegetation obstruction, and excellent solar exposure throughout the year. The minimal slope reduces construction costs and simplifies the installation of solar array infrastructure. The northeastern outskirts of Delicias also offer promising locations for solar development, featuring expansive flat terrain with good drainage characteristics. These areas receive abundant sunlight and have limited competing land uses, making them potentially valuable for renewable energy development. Areas to potentially avoid include the more fertile agricultural lands along the Conchos River valley, where land values may be higher due to agricultural productivity. Additionally, any locations with significant slopes or uneven terrain would increase construction costs and complexity for large-scale solar installations.

Soil and Surface Considerations

The soil composition around Delicias consists predominantly of desert alluvium and sandy loams. These soil types generally provide good stability for solar infrastructure foundations. The relatively stable ground conditions throughout much of the region minimize concerns about soil subsidence or erosion that might otherwise impact large-scale solar installations. Surface drainage patterns should be carefully considered when selecting specific sites, as seasonal rainfall, though limited, can create localized flooding in certain low-lying areas. The optimal locations for solar development would be slightly elevated plains with natural drainage that prevent water accumulation during the region's occasional heavy rainfall events. In conclusion, the topographical characteristics surrounding Delicias offer numerous advantageous locations for solar PV development, with the western and southwestern plains representing particularly promising areas due to their flat terrain, minimal obstruction, and ideal exposure conditions.
