Salisbury, North Carolina, located in the Northern Temperate Zone, offers a relatively favorable environment for solar PV energy generation throughout the year. The city's geographical position at latitude 35.6524 and longitude -80.4915 provides a good balance of sunlight exposure across the seasons.

Seasonal Solar Performance

Solar energy production in Salisbury varies significantly across the four seasons. Summer stands out as the most productive period, with an average daily output of 6.70 kWh per kW of installed solar capacity. Spring follows closely behind, generating 6.07 kWh/day. Autumn sees a moderate decline in production, yielding 4.42 kWh/day. Winter, as expected, has the lowest output at 2.75 kWh/day.

Optimal Times for Solar Generation

The most ideal times for solar energy production in Salisbury are from late spring through early fall. During these months, longer daylight hours and higher sun angles contribute to increased solar panel efficiency. However, even during the less productive winter months, the panels continue to generate a meaningful amount of electricity.

Panel Tilt Optimization

For fixed panel installations in Salisbury, the ideal tilt angle to maximize year-round solar production is 31 degrees facing south. This angle optimizes the panels' exposure to sunlight throughout the year, accounting for seasonal variations in the sun's position.

Environmental and Weather Considerations

While Salisbury's climate is generally conducive to solar energy production, there are a few factors that could potentially impact efficiency:

1. Occasional severe weather events, such as thunderstorms or hurricanes, could temporarily reduce solar output.
2. Humidity and haze during summer months might slightly decrease panel efficiency.

To mitigate these factors, consider the following preventative measures:

• Install durable, weather-resistant panels designed to withstand severe weather conditions.
• Implement a regular cleaning schedule to remove any dust or debris that may accumulate on the panels.
• Use micro-inverters or power optimizers to minimize the impact of partial shading on overall system performance.

Overall, Salisbury's location provides a good balance for year-round solar energy production, with strong performance in summer and spring, and acceptable output even during the winter months.

Note: The Northern Temperate Zone extends from 35° latitude North up to 66.5° latitude.

Solar output per kW of installed solar PV by season in Salisbury, North Carolina

Seasonal solar PV output for Latitude: 35.6524, Longitude: -80.4915 (Salisbury, North Carolina, 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 31° South in Salisbury, North Carolina, United States

To maximize your solar PV system's energy output in Salisbury, North Carolina, United States (Lat/Long 35.6524, -80.4915) throughout the year, you should tilt your panels at an angle of 31° 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 Salisbury, North Carolina, 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 Salisbury, North Carolina, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 31° South tilt angle throughout the year.

Overall Best Summer Angle	Overall Best Autumn Angle	Overall Best Winter Angle	Overall Best Spring Angle
20° South in Summer	41° South in Autumn	51° South in Winter	28° 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 Salisbury, North Carolina, 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 Salisbury, North Carolina, 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 Salisbury, North Carolina, United States

The topography around Salisbury, North Carolina, is characterized by gently rolling hills and shallow valleys typical of the Piedmont region. This area sits between the flat coastal plain to the east and the more mountainous Appalachian region to the west. The landscape is a mix of open fields, wooded areas, and small streams that wind through the countryside. Salisbury itself is situated at an elevation of approximately 760 feet above sea level. The surrounding terrain gradually rises and falls, with elevations ranging from about 600 to 900 feet. This undulating landscape creates a patchwork of slopes and flat areas, with some steeper hillsides interspersed throughout the region.

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 ideal locations would be relatively flat or gently sloping terrain with good southern exposure. These conditions are fairly common in the vicinity of Salisbury, making the region generally favorable for solar development. Some of the most promising areas for solar PV installations would likely be found in the agricultural lands surrounding the city. These open fields often provide the necessary space and sunlight exposure for efficient solar energy production. Particularly suitable locations might include the farmlands to the north and east of Salisbury, where larger tracts of open land are more prevalent. However, it's important to note that specific site selection would require detailed analysis of factors such as local zoning regulations, proximity to electrical infrastructure, and environmental considerations. While the general topography is conducive to solar development, individual locations would need to be assessed for their particular characteristics and potential impacts. Overall, the area around Salisbury offers good potential for solar PV development due to its moderate terrain and abundance of open spaces. The combination of suitable topography and available land makes this region of North Carolina an attractive option for those looking to implement large-scale solar energy projects.

United States solar PV Stats as a country
