Windermere, Florida, located in the Northern Sub Tropics at coordinates 28.5052, -81.5273, offers a favorable environment for solar PV energy generation throughout the year. The location's potential for solar power production varies across seasons, with some periods being more productive than others.
Seasonal Solar Performance
Spring stands out as the most productive season for solar energy in Windermere, with an impressive output of 6.70 kWh per day for each kW of installed solar capacity. Summer follows closely behind, generating 5.88 kWh per day. Autumn sees a slight decrease in production at 4.80 kWh per day, while winter experiences the lowest output at 4.10 kWh per day. These figures indicate that Windermere enjoys substantial solar potential throughout the year, with spring and summer being particularly ideal for solar energy generation. Even during the less productive winter months, the output remains significant, making solar PV a viable year-round energy solution in this location.Optimal Panel Installation
To maximize year-round solar energy production in Windermere, fixed solar panels should be installed at a tilt angle of 26 degrees facing south. This angle has been calculated to optimize energy capture across all seasons, taking into account the sun's changing position throughout the year and the Earth's elliptical orbit.Environmental Considerations
While Windermere's climate is generally conducive to solar energy production, there are a few environmental factors to consider: 1. Humidity: Florida's high humidity levels can potentially impact solar panel efficiency. 2. Tropical storms and hurricanes: These weather events, though infrequent, can pose a risk to solar installations. To mitigate these factors, consider the following preventative measures: • Use high-quality, weather-resistant solar panels designed to withstand humid conditions. • Ensure proper ventilation behind the panels to reduce moisture buildup. • Install a robust mounting system capable of withstanding high winds associated with tropical storms. • Regularly clean panels to remove any dirt or debris that may accumulate due to humid conditions. By implementing these measures, solar installations in Windermere can maintain optimal performance and longevity, capitalizing on the location's excellent solar potential throughout the year.Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

Ideally tilt fixed solar panels 26° South in Windermere, United States
To maximize your solar PV system's energy output in Windermere, United States (Lat/Long 28.5052, -81.5273) 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 Windermere, 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 Windermere, 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 | 44° South in Winter | 21° 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 Windermere, 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 Windermere, United States
The topography around Windermere, located in central Florida, United States, is characterized by its relatively flat terrain with subtle variations in elevation. This area is part of the larger Central Florida region, which is known for its gently rolling landscape dotted with numerous lakes and wetlands. The immediate vicinity of Windermere features a mix of low-lying areas and slightly elevated ridges. The town itself is situated on a narrow strip of land between several lakes, including Lake Butler, Lake Down, and Lake Bessie. These lakes are part of the Butler Chain of Lakes, a series of interconnected water bodies that contribute to the area's unique topography.
Surrounding Landscape
As you move away from Windermere, the landscape maintains its generally flat nature, with occasional small hills and depressions. The region is part of the larger Florida Peninsula, which is predominantly composed of limestone bedrock covered by sandy soils. This geological foundation results in a landscape that is punctuated by numerous sinkholes, springs, and karst features. The area's elevation typically ranges from about 50 to 120 feet above sea level, with minimal dramatic changes in altitude. This relatively uniform topography is interrupted by the presence of numerous water bodies, including lakes, ponds, and wetlands, which add variety to the otherwise level terrain.Potential for Solar PV Development
When considering areas nearby that would be most suited to large-scale solar PV installations, several factors come into play. The flat terrain of central Florida is generally favorable for solar development, as it requires minimal land preparation and allows for efficient panel placement. Areas to the east and south of Windermere, particularly in less developed regions of Orange and Osceola counties, might offer suitable locations for solar farms. These areas often feature expansive agricultural lands or undeveloped parcels that could potentially be repurposed for solar energy production. However, it's important to note that the presence of wetlands and conservation areas in the region may limit the available land for large-scale solar projects. Developers would need to carefully consider environmental impacts and zoning regulations when selecting sites. Additionally, areas slightly inland from the coast, where there is less risk of hurricane damage and salt spray, might be more appropriate for long-term solar installations. These locations would still benefit from Florida's abundant sunshine while potentially facing fewer environmental challenges. In conclusion, while the topography around Windermere is generally conducive to solar PV development due to its flat nature, careful site selection would be necessary to balance energy production potential with environmental considerations and land-use regulations.United States solar PV Stats as a country
