Riddleville, Georgia, located in the Northern Sub Tropics, offers reasonably good conditions for solar energy generation throughout most of the year. The location receives varying amounts of solar energy across the seasons, with some periods being significantly more productive than others.
Seasonal Solar Performance
The solar energy output at this location shows distinct seasonal patterns. Spring delivers the highest production at 6.33 kWh per day per kW of installed solar capacity, closely followed by summer at 6.26 kWh per day. These two seasons represent the peak solar generation period, offering nearly identical and excellent energy production. Autumn sees a notable decrease to 4.64 kWh per day, which is still reasonable for solar energy generation. However, winter presents the most challenging period with only 2.94 kWh per day, representing less than half the production of the peak seasons.Optimal Installation Setup
For maximum year-round energy production at Riddleville, solar panels should be installed at a fixed tilt angle of 29 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's changing position throughout the year and the Earth's elliptical orbit around the sun.Local Factors Affecting Solar Production
Several environmental and weather factors in Georgia can impact solar panel performance at this location:- High humidity levels common in Georgia can reduce solar panel efficiency and create more frequent cleaning requirements
- Severe thunderstorms and occasional hail during spring and summer months pose risks to panel integrity
- Heavy tree coverage typical of Georgia's landscape can create shading issues
- Pollen accumulation, particularly heavy during spring months, can significantly reduce panel efficiency
Preventative Measures for Better Performance
To maximize solar energy production despite these challenges, several installation strategies should be considered:- Install panels with adequate spacing for air circulation to combat humidity-related efficiency losses
- Choose impact-resistant panels and secure mounting systems to withstand severe weather
- Conduct thorough site surveys to identify and remove potential shading from trees or structures
- Plan for regular cleaning schedules, especially during Georgia's intense pollen seasons
- Consider micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance

Ideally tilt fixed solar panels 29° South in Riddleville, United States
To maximize your solar PV system's energy output in Riddleville, United States (Lat/Long 32.9068, -82.6657) 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 Riddleville, 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 Riddleville, 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 |
|---|---|---|---|
| 17° South in Summer | 38° South in Autumn | 48° South in Winter | 25° 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 Riddleville, 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 Riddleville, 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 Riddleville, United States
Topographical Features Around Riddleville
Riddleville sits within the Atlantic Coastal Plain of Georgia, characterized by relatively flat terrain with gentle rolling hills. The landscape consists primarily of sandy soils and clay deposits typical of this southeastern region. Elevations in the immediate area range from approximately 200 to 300 feet above sea level, creating a gently undulating topography that rarely presents steep slopes or dramatic elevation changes. The surrounding countryside features a mix of agricultural fields, pine forests, and scattered wetland areas. Small creeks and tributaries meander through the region, creating occasional low-lying areas and floodplains. These waterways have carved subtle valleys into the landscape over time, though the relief remains modest throughout the area. The terrain becomes slightly more elevated as one moves northwest from Riddleville, while areas to the southeast tend toward lower elevations as they approach the coastal regions of Georgia. Overall, the topography presents few significant obstacles to development, with most of the land exhibiting gradual slopes suitable for various land uses.Optimal Areas for Large-Scale Solar Development
The relatively flat terrain surrounding Riddleville creates favorable conditions for large-scale solar photovoltaic installations. Areas with the most potential lie on the gently sloping uplands northwest and west of the community, where elevations provide good drainage while maintaining manageable grades for construction and maintenance access. Former agricultural fields present particularly attractive opportunities for solar development. These cleared areas already possess the open canopy necessary for solar installations and often feature relatively level ground that requires minimal site preparation. The sandy soils common to the region provide adequate drainage while being suitable for various foundation systems used in solar installations. Areas with south-facing slopes, even gentle ones, offer additional advantages for solar panel orientation and efficiency. The rolling hills northwest of Riddleville contain several such locations that combine favorable topography with existing cleared land. Developers should avoid the lower-lying areas near creek beds and wetlands, as these locations may present drainage challenges and environmental restrictions. Additionally, heavily forested areas, while potentially suitable from a topographical standpoint, would require significant clearing that could impact project economics and environmental considerations. The overall gentle nature of the terrain means that most upland areas within a reasonable distance of Riddleville could accommodate solar installations with appropriate engineering and site design. The key factors become land availability, proximity to electrical infrastructure, and local zoning considerations rather than topographical limitations.United States solar PV Stats as a country
