Lilburn, Georgia, located in the Northern Sub Tropics, offers a generally favorable environment for solar energy production throughout the year. The city's geographical position at latitude 33.852 and longitude -84.1152 provides ample sunlight for photovoltaic (PV) systems, with varying levels of efficiency across seasons.
Seasonal Solar Performance
Solar energy generation in Lilburn experiences significant fluctuations across the four seasons. Summer stands out as the most productive period, with an impressive daily output of 6.21 kWh per kW of installed solar capacity. Spring follows closely behind, yielding 6.06 kWh/day. Autumn sees a moderate decrease in production at 4.54 kWh/day, while winter experiences the lowest output at 2.84 kWh/day.
The substantial difference between summer and winter production highlights the impact of seasonal variations on solar energy generation in this region. However, the relatively high output during spring and autumn suggests that Lilburn maintains good solar potential for a significant portion of the year.
Optimal Panel Installation
For those considering a fixed panel installation in Lilburn, the ideal angle to maximize year-round solar production is 30 degrees tilted towards the South. This angle has been calculated to optimize energy capture across all seasons, taking into account the Earth's elliptical orbit and the location's specific latitude.
Environmental Considerations
While Lilburn generally provides favorable conditions for solar energy production, there are some environmental factors to consider:
- Tree coverage: Lilburn is known for its lush vegetation, which may cast shadows on solar panels.
- Seasonal weather patterns: The area can experience occasional severe storms, particularly during spring and summer.
To mitigate these factors, it's advisable to conduct a thorough site assessment before installation. Trimming or removing obstructing trees and positioning panels to minimize shading can significantly improve energy production. Additionally, using durable, weather-resistant panels and proper mounting systems can help protect the installation from potential storm damage.
In conclusion, Lilburn, Georgia presents a good location for solar PV installations, with particularly strong potential during the spring and summer months. While winter production is notably lower, the overall yearly output remains favorable. With proper planning and installation techniques, residents can effectively harness solar energy throughout the year.

Ideally tilt fixed solar panels 30° South in Lilburn, United States
To maximize your solar PV system's energy output in Lilburn, United States (Lat/Long 33.852, -84.1152) throughout the year, you should tilt your panels at an angle of 30° 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 Lilburn, 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 Lilburn, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 30° 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 | 26° 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 Lilburn, 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 Lilburn, 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 Lilburn, United States
The topography around Lilburn, Georgia, located in the southeastern United States, is characterized by gently rolling hills and shallow valleys typical of the Piedmont region. This area sits at the foothills of the Appalachian Mountains, with an average elevation of around 1,000 feet above sea level. The landscape is a mix of suburban development, wooded areas, and small streams that wind through the terrain. Lilburn and its surrounding areas feature a combination of open spaces, residential neighborhoods, and pockets of commercial development. The land gradually rises as you move north and east towards the Appalachian foothills, while it becomes slightly flatter towards the south and west. The region experiences a humid subtropical climate, with hot summers and mild winters, which can influence the effectiveness of solar energy production.
Suitable Areas for Large-Scale Solar PV
When considering areas near Lilburn for large-scale solar photovoltaic (PV) installations, several factors come into play. The most suitable locations would be relatively flat, open spaces with minimal shading from trees or buildings. These areas should also have good access to existing electrical infrastructure for easy integration into the power grid. Some of the more promising areas for large-scale solar PV near Lilburn might include: 1. Former agricultural land to the east and southeast of Lilburn, where there are larger open spaces that have been cleared of trees. 2. Undeveloped parcels of land along major highways, such as areas near Interstate 85 to the southwest of Lilburn. 3. Brownfield sites or former industrial areas in nearby cities like Norcross or Lawrenceville, which may offer large, flat surfaces ideal for solar panel installation. 4. Open spaces near existing power substations or transmission lines, which would reduce the cost and complexity of connecting to the electrical grid. It's important to note that while the rolling terrain around Lilburn may present some challenges for large-scale solar installations, modern solar panel technology and creative land use strategies can often overcome these obstacles. Additionally, any large-scale solar project would need to comply with local zoning laws and environmental regulations, which may further influence site selection in the area.United States solar PV Stats as a country
