Bluffton, South Carolina, located in the Northern Sub Tropics at 32.2508°N, 80.8718°W, offers a relatively favorable environment for solar PV energy generation throughout the year. The location's seasonal solar output varies, with peak production occurring during the spring and summer months.

Seasonal Solar Performance

Spring stands out as the most productive season, with an impressive 6.59 kWh/day per kW of installed solar capacity. Summer follows closely behind at 6.37 kWh/day. Autumn sees a moderate decrease to 4.71 kWh/day, while winter experiences the lowest output at 3.14 kWh/day per kW installed.

The substantial difference between winter and spring/summer production highlights the impact of seasonal variations on solar energy generation in Bluffton. Despite the winter dip, the area maintains a respectable year-round solar potential, making it a viable location for solar PV installations.

Optimal Panel Tilt

For fixed panel installations in Bluffton, the ideal tilt angle to maximize year-round solar production is 28 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for the location's latitude and the Earth's elliptical orbit.

Environmental Considerations

While Bluffton's climate is generally conducive to solar energy production, there are some environmental factors to consider:

1. Humidity: The area's subtropical climate can lead to high humidity levels, potentially affecting panel efficiency.
2. Tropical storms and hurricanes: Bluffton's coastal location makes it susceptible to severe weather events during the Atlantic hurricane season.

To mitigate these factors, solar installations should incorporate robust mounting systems capable of withstanding high winds. Additionally, regular cleaning and maintenance can help combat efficiency losses due to humidity-related issues such as mold or algae growth on panels.

In conclusion, Bluffton, South Carolina, presents a good opportunity for solar PV energy generation, with strong performance in spring and summer offsetting the winter decline. By optimizing panel tilt and addressing environmental challenges, solar installations in this location can achieve consistent and efficient year-round energy production.

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

Seasonal solar PV output for Latitude: 32.2508, Longitude: -80.8718 (Bluffton, 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 28° South in Bluffton, United States

To maximize your solar PV system's energy output in Bluffton, United States (Lat/Long 32.2508, -80.8718) throughout the year, you should tilt your panels at an angle of 28° 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 Bluffton, 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 Bluffton, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 28° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
16° South in Summer	37° South in Autumn	48° South in Winter	25° 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 Bluffton, 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 Bluffton, 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 Bluffton, United States

The area around Bluffton, South Carolina, located at 32.2508°N latitude and 80.8718°W longitude, is characterized by a relatively flat, low-lying coastal plain topography. This region is part of the South Carolina Lowcountry, known for its gentle slopes, numerous waterways, and marshy areas. Bluffton itself sits on a bluff overlooking the May River, which explains its name. The surrounding landscape is dominated by tidal creeks, salt marshes, and coastal forests. The terrain is generally flat to gently rolling, with elevations typically ranging from sea level to about 20-30 feet above sea level. This low-lying nature of the land makes it susceptible to flooding during storms and high tides.

Nearby Areas Suitable for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal location would have ample open space, relatively flat terrain, and good sun exposure throughout the day. Given these criteria, the areas just inland from Bluffton, moving towards Hardeeville and Ridgeland, might offer more suitable locations for large-scale solar PV projects. These areas tend to have more open, rural land with fewer obstructions that could cast shadows on solar panels. The terrain in these inland areas remains relatively flat, which is advantageous for solar panel installation and maintenance. However, it's important to note that the entire region experiences high humidity and frequent cloud cover, which can impact solar energy production. Additionally, the risk of hurricanes and flooding in coastal areas should be taken into consideration when planning large-scale solar installations. Specific sites would need to be carefully evaluated for factors such as soil stability, drainage, and proximity to existing power infrastructure. Environmental impact assessments would also be crucial, given the ecological sensitivity of the Lowcountry region. Any large-scale solar project would need to balance energy production goals with the preservation of the area's unique coastal ecosystems and wildlife habitats.

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]

Are there incentives for businesses to install solar in United States?
