Oviedo, Florida, located in the Northern Sub Tropics at coordinates 28.6529, -81.2106, offers a generally favorable environment for solar PV energy generation throughout the year. The location experiences varying levels of solar production across the four seasons, with some distinct patterns worth noting.

Seasonal Solar Production

Spring stands out as the most productive season in Oviedo, generating an impressive 6.69 kWh per day for each kilowatt of installed solar capacity. Summer follows with 5.89 kWh/day, while autumn produces 4.75 kWh/day. Winter, as expected, shows the lowest output at 4.03 kWh/day per kilowatt of installed capacity, though this is still relatively productive compared to many northern locations.

The highest production period spans from March through August, with a notable peak during spring months. This makes spring an ideal time for solar energy generation in Oviedo, though the relatively strong performance in summer means that air conditioning loads, which typically peak during hot summer days, can be partially offset by solar production.

Optimal Panel Installation

For fixed-panel solar installations in Oviedo, the ideal tilt angle to maximize year-round production is 26 degrees facing South. This angle optimizes the capture of solar energy throughout the year, accounting for the region's subtropical latitude and seasonal sun positions.

Environmental and Weather Considerations

Several significant factors can affect solar production in Oviedo:

• Afternoon thunderstorms, particularly common during summer months, can temporarily reduce solar output during what would otherwise be peak production hours.
• Hurricane season (June through November) poses risks of severe weather events that could damage installations or cause extended cloudy periods.
• High humidity levels can create morning fog or haze that might delay peak production until later in the day.
• Tree coverage is substantial in many Oviedo neighborhoods, potentially creating shading issues.

Preventative Measures

To maximize solar production despite these challenges, consider these preventative measures:

• Install hurricane-rated mounting systems designed to withstand high winds up to the region's building code requirements.
• Conduct thorough shade analysis before installation, including seasonal sun path studies to identify potential obstructions.
• Consider micro-inverters or power optimizers for systems where partial shading is unavoidable, allowing unshaded panels to continue producing efficiently.
• Implement regular cleaning schedules, especially during pollen season (early spring) and after major storms, to maintain optimal panel efficiency.
• Design systems with slightly higher capacity to compensate for the inevitable production losses during Florida's frequent but short-duration afternoon storms.

Despite these challenges, Oviedo's location provides substantial solar potential throughout the year, with even the lowest-producing winter months delivering reasonable output compared to many other U.S. locations.

Note: The Northern Sub Tropics extend from 23.5° latitude North up to 35° latitude.

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

Seasonal solar PV output for Latitude: 28.6529, Longitude: -81.2106 (Oviedo, 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 Oviedo, United States

To maximize your solar PV system's energy output in Oviedo, United States (Lat/Long 28.6529, -81.2106) 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 Oviedo, 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 Oviedo, 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 Oviedo, 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 Oviedo, 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 Oviedo, United States

The topography around Oviedo, Florida, located in Seminole County, is characterized by a gentle, predominantly flat landscape typical of central Florida. Situated at an elevation of approximately 35-45 feet above sea level, Oviedo lies within the Central Florida Ridge region. The area features subtle undulations rather than dramatic elevation changes, with occasional small hills and depressions that rarely exceed 50-75 feet in relative height difference. Water features significantly influence the local topography. Numerous lakes dot the landscape around Oviedo, including Lake Jesup to the north and the smaller Lake Mills. These bodies of water create natural depressions in the otherwise level terrain. The Little Econlockhatchee River also flows through the region, carving shallow valleys and contributing to the area's drainage system.

Soil and Ground Composition

The ground composition around Oviedo consists primarily of sandy soils typical of Florida's central region. These soils are generally well-draining, though areas closer to water bodies may contain more organic material and moisture retention. Limestone underlies much of the region, occasionally creating karst topography features like sinkholes, though these are less common than in other parts of Florida. Vegetation naturally influences the perceived topography, with pine flatwoods and oak hammocks being common in the area. Some wetland areas exist, particularly around the water bodies and drainage systems, creating slight variations in the landscape's appearance.

Optimal Areas for Solar PV Development

For large-scale solar photovoltaic (PV) development near Oviedo, several areas present favorable conditions based on topographical considerations: The flat, open lands to the east of Oviedo, extending toward the less developed areas of eastern Seminole County, offer excellent potential for solar installations. These areas feature minimal elevation changes, reducing construction complexities and associated costs. The relatively sparse vegetation in certain sections would require less clearing, minimizing environmental impact and site preparation expenses. Former agricultural lands surrounding the community also present opportunities. These areas typically feature cleared, level ground with established access routes, making them particularly suitable for solar development. The southwestern portions of Seminole County, where urban density decreases, contain parcels of land with favorable solar potential due to their open, unobstructed nature. Areas with slight southern-facing slopes, though rare in this predominantly flat region, would offer marginally improved solar efficiency where they do exist. The sandy soil composition generally provides good drainage and stable foundation conditions for mounting systems, though site-specific geotechnical assessments would be necessary. Areas to avoid would include wetlands near Lake Jesup and the river systems, conservation areas, and the more densely developed portions of Oviedo proper. The presence of numerous lakes and water features throughout the region also creates exclusion zones where development would be impractical or environmentally problematic. The relatively flat topography throughout the region means that shading from natural features is minimal, making most non-developed, non-protected areas potentially suitable from a purely topographical perspective. The primary limiting factors would more likely be land availability, proximity to transmission infrastructure, and local zoning regulations rather than topographical constraints.
