Beeville, Texas, located in the Northern Sub Tropics, offers reasonably good conditions for year-round solar energy generation, though with notable seasonal variations that potential solar installers should understand.

Seasonal Solar Performance

The solar energy output at this location varies significantly throughout the year. Summer provides the strongest performance at 6.86 kWh per day per kW of installed solar capacity, making it the ideal season for solar generation. Spring follows as the second-best season with 5.32 kWh per day per kW, while autumn produces 5.15 kWh per day per kW. Winter presents the greatest challenge for solar production, dropping to just 3.45 kWh per day per kW of installed capacity. This represents a 50% reduction compared to summer output, which is typical for locations at this latitude but still allows for meaningful energy production year-round.

Optimal Installation Setup

For fixed panel installations at Beeville, the ideal tilt angle is 25 degrees facing south to maximize total year-round solar production. This angle has been calculated to provide the best balance across all seasons by accounting for the sun's changing position throughout the year and weighting for actual solar irradiance data.

Local Environmental Challenges

Several environmental and weather factors in the Beeville area can impact solar panel performance:

• High humidity and frequent thunderstorms, particularly during summer months, can reduce solar irradiance and create safety concerns during installation and maintenance
• Dust accumulation from agricultural activities and dry periods can coat panels and reduce efficiency
• Potential for severe weather including hail storms and high winds associated with Gulf Coast weather patterns
• Salt air corrosion from proximity to the Gulf of Mexico may affect equipment longevity

Preventative Measures for Better Performance

To maximize solar energy production despite these challenges, several preventative measures should be considered during installation: Regular cleaning schedules become essential due to dust accumulation. Installing panels with anti-soiling coatings or self-cleaning surfaces can help maintain efficiency between manual cleanings. Proper drainage design prevents water pooling during heavy rains. Choosing equipment rated for high humidity and corrosive environments helps ensure longevity. This includes using marine-grade wiring, corrosion-resistant mounting hardware, and panels with robust frame materials designed for coastal conditions. Structural considerations for high winds and potential hail damage should include reinforced mounting systems and impact-resistant panel glass. Installing lightning protection systems becomes particularly important given the frequency of thunderstorms in this region. Overall, while Beeville presents some environmental challenges for solar installations, proper planning and equipment selection can help ensure reliable year-round energy production, with summer and spring offering particularly strong performance periods.

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

Seasonal solar PV output for Latitude: 28.4222, Longitude: -97.7616 (Beeville, United States), 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 Beeville, United States

To maximize your solar PV system's energy output in Beeville, United States (Lat/Long 28.4222, -97.7616) 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 Beeville, United States

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 Beeville, United States. 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
13° South in Summer	33° 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 Beeville, United States

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 Beeville, United States.

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 Beeville, United States

Topography Around Beeville, Texas

The landscape surrounding Beeville, Texas is characterized by gently rolling plains that form part of the South Texas Coastal Plain region. This area sits at a relatively low elevation, approximately 200 to 250 feet above sea level, with subtle undulations across the terrain rather than dramatic elevation changes. The topography consists primarily of broad, open grasslands interspersed with scattered mesquite and oak trees, creating a semi-arid environment typical of south-central Texas. The region features well-drained soils developed over ancient marine sediments, with occasional shallow depressions and dry creek beds that channel seasonal rainfall. These natural drainage patterns create a mosaic of slightly higher ridges and lower-lying areas, though the overall relief remains modest throughout the vicinity. The terrain gradually slopes toward the southeast in the direction of the Gulf Coastal Plain, with no significant hills or mountainous features to obstruct solar exposure.

Optimal Areas for Large-Scale Solar Development

The expansive flat to gently rolling terrain southwest and northwest of Beeville presents ideal conditions for utility-scale solar photovoltaic installations. These areas offer extensive tracts of relatively level land with minimal tree cover, reducing both development costs and shading concerns. The consistent topography allows for efficient panel arrangement and maintenance access while minimizing grading requirements. Agricultural lands in the surrounding counties, particularly those currently used for cattle grazing, represent prime candidates for solar development due to their open character and existing infrastructure access. The areas along major transportation corridors, including regions near Highway 181 and Highway 59, provide additional advantages through proximity to electrical transmission infrastructure and improved logistics for construction and ongoing operations. The southeastern portions toward the coastal plain also offer suitable terrain, though developers should consider seasonal drainage patterns and soil conditions in these lower-elevation areas. The relatively uniform topography throughout the region means that site selection can focus primarily on land availability, transmission access, and local zoning considerations rather than being constrained by challenging terrain features.
