Solar PV Analysis of Alvin, United States
Alvin, Texas, located in the Northern Sub Tropics at latitude 29.4085 and longitude -95.2499, offers a generally favorable environment for solar PV energy generation throughout the year. The location's seasonal solar output varies, with summer being the most productive season and winter the least.
Seasonal Solar Production
Summer stands out as the peak season for solar energy production in Alvin, with an impressive 6.38 kWh per day for each kilowatt of installed solar capacity. Spring follows as the second most productive season, generating 5.24 kWh/day. Autumn sees a slight decrease in output at 4.89 kWh/day, while winter experiences the lowest production at 3.32 kWh/day per kW installed.
The substantial difference between summer and winter production highlights the importance of proper system sizing to ensure adequate energy supply during less productive months. Despite the winter dip, Alvin's year-round solar potential remains relatively strong compared to many other locations in the United States.
Optimal Panel Tilt
For fixed panel installations in Alvin, the ideal tilt angle to maximize year-round solar production is 26 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for seasonal variations in the sun's position.
Environmental Considerations
While Alvin's climate is generally conducive to solar energy production, there are some environmental factors to consider:
- Hurricane risk: Alvin's proximity to the Gulf Coast makes it vulnerable to hurricanes, which could potentially damage solar installations.
- High humidity: The area's humid subtropical climate may lead to increased dust accumulation on panels, potentially reducing efficiency.
Preventative Measures
To mitigate these environmental challenges and ensure optimal solar production, consider the following measures:
- Install hurricane-resistant mounting systems and high-quality, impact-resistant panels.
- Implement a regular cleaning schedule to combat dust buildup from humidity.
- Use micro-inverters or power optimizers to minimize the impact of partial shading or panel damage.
- Consider a ground-mounted system for easier maintenance and storm preparation.
Overall, Alvin, Texas provides a suitable location for solar PV installations, with strong potential for energy generation throughout the year, particularly from spring through fall. By addressing the specific environmental challenges of the area, solar system owners can maximize their energy production and protect their investment.

Solar output per kW of installed solar PV by season in Alvin
Seasonal solar PV output for Latitude: 29.4085, Longitude: -95.2499 (Alvin, 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 26° South in Alvin, United States
To maximize your solar PV system's energy output in Alvin, United States (Lat/Long 29.4085, -95.2499) 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 Alvin, 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 Alvin, United States. 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 | 45° South in Winter | 23° 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 Alvin, 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 Alvin, United States.
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 Alvin, United States
The topography around Alvin, Texas (located at 29.4085° N, 95.2499° W) is predominantly flat to gently rolling. This area is part of the Gulf Coastal Plain, characterized by low elevations and minimal relief. The landscape is mostly comprised of coastal prairies and grasslands, with some scattered woodlands and wetlands.
Alvin sits at an average elevation of about 51 feet (15.5 meters) above sea level. The terrain gradually slopes downward as you move southeast towards the Gulf of Mexico, which is approximately 20 miles away. To the northwest, the land rises slightly but remains relatively flat.
The region's geology consists of sedimentary deposits, including clay, sand, and silt, laid down over millions of years by ancient rivers and coastal processes. This results in generally good soil drainage in many areas, although some low-lying spots may be prone to flooding during heavy rainfall events.
For large-scale solar PV installations, the areas most suited would be the open, flat grasslands and prairies surrounding Alvin. These locations offer several advantages:
- Minimal land preparation required due to the naturally flat terrain
- Abundant open space with few obstructions to block sunlight
- Good solar exposure due to the lack of significant hills or mountains
- Relatively easy access for construction and maintenance
Ideal sites would be found in the rural areas to the west and southwest of Alvin, where there are expansive tracts of agricultural land and open fields. These areas provide ample space for large solar arrays while being far enough from residential zones to minimize potential conflicts with local communities.
However, when considering solar PV installations in this region, it's important to factor in the proximity to the Gulf Coast and the associated weather patterns. The area can experience hurricanes and tropical storms, which could potentially damage solar infrastructure. Therefore, any large-scale solar projects would need to incorporate robust design features to withstand high winds and heavy rainfall.
Additionally, while the flat terrain is generally advantageous, care should be taken to avoid low-lying areas prone to flooding or wetlands, which are ecologically sensitive and may be subject to environmental protection regulations.
