Longwood, Florida, situated in the Northern Sub Tropics, offers a promising location for solar energy generation throughout the year. The city's geographical position at latitude 28.7102 and longitude -81.3536 provides favorable conditions for harnessing solar power.

Seasonal Solar Performance

Solar panel efficiency in Longwood varies across seasons, with spring and summer being the most productive periods. During spring, solar panels can generate an impressive 6.70 kWh per day for each kilowatt of installed capacity. Summer follows closely with 5.88 kWh/day, while autumn and winter see slightly reduced output at 4.80 kWh/day and 4.10 kWh/day, respectively.

Optimal Panel Angle

For fixed panel installations in Longwood, the ideal tilt angle to maximize year-round solar production is 26 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the Earth's elliptical orbit and the location's specific latitude.

Peak Production Periods

The most ideal times for solar energy generation in Longwood are during spring and summer. Longer daylight hours and higher sun angles during these seasons contribute to increased solar panel efficiency. However, it's worth noting that even during the less productive autumn and winter months, the solar output remains relatively high compared to many other locations in the United States.

Environmental Factors and Mitigation

While Longwood's climate is generally favorable for solar energy production, there are a few environmental factors to consider: 1. Humidity: Florida's high humidity levels can potentially reduce solar panel efficiency. To mitigate this, proper ventilation and regular cleaning of panels can help maintain optimal performance. 2. Tropical storms and hurricanes: Longwood's proximity to the coast makes it susceptible to severe weather events. Installing sturdy mounting systems and using impact-resistant panels can help protect the solar installation during storms. 3. Afternoon thunderstorms: Common in Florida, these can temporarily reduce solar output. Incorporating energy storage solutions, such as batteries, can help balance energy production during cloudy periods.

Conclusion

Overall, Longwood, Florida, presents an excellent location for year-round solar energy generation. With proper installation techniques and regular maintenance, solar PV systems in this area can provide consistent and substantial energy output throughout the year, making it a worthwhile investment for both residential and commercial applications.

Solar output per kW of installed solar PV by season in Longwood

Seasonal solar PV output for Latitude: 28.7102, Longitude: -81.3536 (Longwood, United States), based on our analysis of 8760 hourly intervals of solar and meteorological data (one whole year) retrieved for that set of coordinates/location from NASA POWER (The Prediction of Worldwide Energy Resources) API:

 

Ideally tilt fixed solar panels 26° South in Longwood, United States

To maximize your solar PV system's energy output in Longwood, United States (Lat/Long 28.7102, -81.3536) 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 Longwood, 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 Longwood, 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	22° 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 Longwood, 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 Longwood, United States.

Our calculation method

1. Solar Position:
   We determine the Sun's position on the Winter solstice using the location's latitude and solar declination.
2. Shadow Projection:
   We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle.
3. 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 Longwood, United States

The area around Longwood, Florida, located at approximately 28.7102° N latitude and 81.3536° W longitude, is characterized by a relatively flat topography typical of central Florida. This region is part of the larger Central Florida Ridge, which is a slightly elevated area compared to the coastal plains. The landscape consists of gently rolling hills, with elevations generally ranging from about 20 to 60 feet above sea level. The topography of Longwood and its surrounding areas is dotted with numerous small lakes, ponds, and wetlands, which are remnants of ancient sinkholes formed in the underlying limestone bedrock. These water features contribute to the area's unique ecosystem and provide habitats for various flora and fauna.

Solar PV Potential

When considering areas nearby that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The flat terrain and abundance of open spaces in the region surrounding Longwood make it potentially suitable for solar energy development. Areas to the east and southeast of Longwood, towards the less developed regions of Seminole and Orange counties, could be particularly well-suited for large-scale solar PV projects. These areas often have more available land that is not heavily forested or urbanized, which is ideal for solar panel installation. The relatively consistent elevation and lack of significant geographical obstructions in these areas would minimize shading issues, allowing for optimal sun exposure throughout the day. Additionally, the region's subtropical climate, with its abundance of sunny days, further enhances the potential for solar energy production. However, it's important to note that any large-scale solar PV development would need to consider environmental factors, such as the impact on local ecosystems and wildlife habitats. Areas with fewer wetlands and protected natural spaces would be preferable to minimize ecological disruption. Ultimately, the most suitable locations for large-scale solar PV near Longwood would be those that combine favorable topography, ample open space, minimal environmental impact, and proximity to existing power infrastructure. Detailed site-specific studies would be necessary to determine the optimal locations for such projects.

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. This means that 3.40% of United States's total energy as a country comes from solar PV (that's 26th in the world). Each year United States is generating 289 Watts from solar PV per capita (United States ranks 15th in the world for solar PV Watts generated per capita). [source]
