Pine Bluff, Arkansas, located in the Northern Sub Tropics at coordinates 34.1892, -92.0495, presents a moderately favorable location for year-round solar energy generation, though with significant seasonal variations that potential solar installers should carefully consider.
Seasonal Solar Performance
The location shows strong summer performance with solar panels generating 6.72 kWh per day per kW of installed capacity during the peak season. Spring also delivers solid results at 5.41 kWh per day per kW, making these the most productive months for solar energy generation. However, the location faces challenges during cooler months, with autumn dropping to 4.38 kWh per day per kW and winter showing the lowest output at just 2.55 kWh per day per kW installed. This seasonal variation means that while summer and spring provide excellent solar generation opportunities, winter production drops to less than 40% of summer levels. Property owners considering solar installation should factor this significant seasonal swing into their energy planning and potentially consider battery storage systems to help balance the seasonal differences. For optimal year-round performance, solar panels at this Pine Bluff location should be installed at a fixed tilt angle of 29 degrees facing south. This angle maximizes total annual energy production by accounting for the sun's changing position throughout the year and the varying solar irradiance levels at this latitude.Environmental and Weather Challenges
Several local factors in Pine Bluff, Arkansas could potentially impact solar panel performance and require preventative measures during installation:- Severe Weather Events: Arkansas experiences tornadoes, hailstorms, and high winds that can damage solar installations
- High Humidity and Heat: The subtropical climate creates conditions that can reduce panel efficiency and accelerate equipment degradation
- Ice Storms: Winter ice accumulation can block panels and create dangerous conditions for maintenance
- Heavy Rainfall: Frequent storms can lead to water infiltration issues if systems aren't properly sealed
Recommended Preventative Measures
To maximize solar energy production and system longevity in Pine Bluff's climate, several installation strategies should be implemented. Choose panels and mounting systems rated for high wind loads and hail impact, as these will better withstand Arkansas's severe weather patterns. Ensure all electrical connections use weatherproof enclosures and marine-grade wiring to handle the high humidity levels common in this subtropical region. Install panels with adequate spacing and ventilation underneath to promote air circulation, which helps combat efficiency losses from high temperatures. Consider micro-inverters or power optimizers rather than string inverters, as these can minimize production losses when individual panels are shaded or soiled. Regular maintenance becomes particularly important in this climate. Schedule professional cleaning and inspections at least twice yearly, with additional checks after major weather events. Install monitoring systems that can quickly identify performance issues, allowing for prompt maintenance that keeps the system operating at peak efficiency despite the challenging environmental conditions.Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 29° South in Pine Bluff, United States
To maximize your solar PV system's energy output in Pine Bluff, United States (Lat/Long 34.1892, -92.0495) throughout the year, you should tilt your panels at an angle of 29° 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 Pine Bluff, 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 Pine Bluff, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 29° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 18° South in Summer | 39° South in Autumn | 49° South in Winter | 27° 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 Pine Bluff, 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 Pine Bluff, 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 Pine Bluff, United States
Topographical Features of Pine Bluff
Pine Bluff sits in the Arkansas River Valley region of central Arkansas, positioned at an elevation of approximately 200 feet above sea level. The city is located along the Arkansas River, which flows in a generally southeastern direction through this part of the state. The terrain around Pine Bluff is characterized by relatively flat to gently rolling topography, typical of the Mississippi River Delta Plain region that extends westward into Arkansas. The landscape features low-lying areas near the Arkansas River, with slightly higher ground extending outward from the river valley. Much of the surrounding countryside consists of agricultural fields and former agricultural land, creating expanses of relatively open terrain. The area includes scattered woodlands, particularly along waterways and in areas that have not been cleared for farming.Regional Terrain Characteristics
The broader region around Pine Bluff exhibits minimal elevation changes, making it part of the Gulf Coastal Plain physiographic province. Rolling hills are present but tend to be gentle, with elevation differences typically ranging from about 150 to 300 feet above sea level within a reasonable distance of the city. The Arkansas River and its tributaries have created a network of valleys and floodplains that contribute to the generally flat character of the landscape. Wetlands and bottomland forests occur along the river systems, while upland areas often feature mixed pine and hardwood forests where land has not been converted to agricultural use. The soil composition varies from sandy loams on higher ground to heavier clay soils in bottomland areas.Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Pine Bluff would be the open agricultural areas and cleared lands on the slightly elevated terrain away from the immediate river floodplain. These areas offer several advantages including relatively flat topography that minimizes grading requirements, good drainage characteristics, and existing road access from agricultural use. Areas to the north, east, and west of Pine Bluff present particularly favorable conditions, where former farmland or current agricultural areas provide large contiguous parcels of land. The gentle slopes in these areas are ideal for solar installations as they allow for optimal panel orientation while maintaining good drainage. These locations also tend to have fewer trees and other obstructions that could create shading issues. The slightly elevated areas between Pine Bluff and surrounding communities would be preferable to locations closer to the Arkansas River, as they avoid potential flooding concerns and typically have better soil stability. Agricultural areas that have been recently cleared or are in transition from active farming present excellent opportunities, as the land preparation requirements would be minimal and existing infrastructure such as access roads may already be in place.United States solar PV Stats as a country
United States ranks 2nd in the world for cumulative solar PV capacity, with 95,209 total MW's of solar PV installed.
