Yulee, Florida presents a moderately favorable location for year-round solar energy generation, situated in the Northern Sub Tropics at coordinates 30.6215, -81.5914. The area experiences significant seasonal variation in solar production, making it important to understand the best and worst times for energy generation.
Seasonal Solar Performance
Spring emerges as the peak season for solar energy production in Yulee, delivering an impressive 6.41 kWh per day per kW of installed solar capacity. This represents the optimal time of year when the sun angle and weather conditions align most favorably for photovoltaic systems. Summer follows closely behind with 5.84 kWh per day per kW, providing strong and consistent energy output during the longer days. Autumn sees a notable decline to 4.64 kWh per day per kW as the sun angle decreases and daylight hours shorten. Winter presents the most challenging period for solar generation, dropping to just 3.43 kWh per day per kW. This represents nearly a 47% reduction compared to the peak spring production, highlighting the importance of proper system sizing to meet energy needs during these lower-output months.Optimal Panel Configuration
For maximum year-round solar production at this Yulee location, solar panels should be installed at a fixed tilt angle of 27 degrees facing south. This angle has been calculated to optimize total annual energy output by accounting for the sun's changing position throughout the year and weighting for actual solar irradiance conditions.Environmental and Weather Challenges
Several significant environmental factors in the Yulee area can impact solar energy production and require careful consideration during installation:- Hurricane and severe storm activity: North Florida experiences regular tropical weather systems that can damage solar installations through high winds, flying debris, and hail
- High humidity and salt air exposure: The coastal proximity creates corrosive conditions that can degrade electrical components and panel frames over time
- Heavy seasonal rainfall: While rain can help clean panels, extended periods of cloud cover during storm seasons reduce energy output
- Spanish moss and tree coverage: The subtropical environment promotes heavy vegetation growth that can create shading issues
Protective Installation Measures
To maximize energy production and system longevity in Yulee's challenging environment, several preventative measures should be implemented:- Enhanced structural mounting: Use hurricane-rated mounting systems designed to withstand winds exceeding 150 mph, with proper engineering calculations for local wind loads
- Corrosion-resistant materials: Select aluminum rails and stainless steel hardware with marine-grade coatings to resist salt air degradation
- Strategic vegetation management: Maintain regular tree trimming schedules and remove Spanish moss that could shade panels, especially during peak production seasons
- Elevated installation height: Mount panels high enough to avoid flood damage during storm surge events common to coastal areas
- Quality electrical components: Use inverters and electrical equipment rated for high humidity environments with proper weatherproof enclosures
Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 27° South in Yulee, United States
To maximize your solar PV system's energy output in Yulee, United States (Lat/Long 30.6215, -81.5914) throughout the year, you should tilt your panels at an angle of 27° 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 Yulee, 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 Yulee, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 27° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 15° South in Summer | 35° South in Autumn | 46° 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 Yulee, 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 Yulee, 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 Yulee, United States
Topographical Features of the Yulee Region
The area surrounding Yulee, Florida presents a relatively flat coastal plain landscape typical of northeastern Florida. This region sits at a low elevation, generally ranging from sea level to approximately 30 feet above sea level, creating a predominantly level terrain with gentle undulations. The topography is characterized by sandy soils and subtle ridges that formed over thousands of years through ancient marine and fluvial processes. Wetlands and marshes are prominent features throughout the landscape, particularly as one approaches the Atlantic coast to the east and the various tidal creeks and rivers that meander through the region. These low-lying areas often experience seasonal flooding and maintain high water tables year-round. The Amelia River and its tributaries create natural drainage patterns that influence the local topography, carving shallow valleys and creating slightly elevated areas between waterways. Pine flatwoods dominate much of the natural vegetation, interspersed with hardwood hammocks on slightly higher ground. The terrain shows evidence of historical agricultural use, with many areas having been cleared and modified for farming operations, particularly for row crops and pastureland.Optimal Areas for Large-Scale Solar Development
The most suitable locations for extensive solar photovoltaic installations would be the elevated sandy ridges and previously cleared agricultural lands that offer good drainage and stable soil conditions. These areas typically lie inland from the immediate coastal zone, avoiding the wetlands and flood-prone regions while taking advantage of the naturally level terrain that requires minimal grading for solar panel installation. Former agricultural fields and pastures present excellent opportunities for solar development, as they often feature already-cleared land with established access roads and proximity to existing electrical infrastructure. The slightly higher elevations found along the historic ridgelines provide additional benefits by ensuring better drainage during heavy rainfall events and reducing concerns about seasonal water table fluctuations. Areas to avoid would include the extensive wetlands, floodplains, and marshes that are environmentally sensitive and subject to regular inundation. The immediate coastal zones also present challenges due to salt spray exposure and potential storm surge impacts. The most promising locations lie in the transitional zones between the coastal lowlands and the inland areas, where the topography provides sufficient elevation while maintaining the flat characteristics ideal for solar array construction. The region's generally uniform topography means that large contiguous areas suitable for solar development are readily available, particularly in locations where previous land use has already modified the natural landscape for human activities.United States solar PV Stats as a country
