While Winston-Salem's climate is generally conducive to solar energy production, there are some factors that could potentially impact efficiency: 1. Cloudy days: The region experiences an average of 220 sunny days per year, which is slightly above the U.S. average. However, cloud cover during the remaining days can temporarily reduce solar output. 2. Seasonal storms: Winston-Salem may face occasional severe weather, including thunderstorms and rare hurricanes, which could temporarily affect solar production. To mitigate these factors, consider the following preventative measures:

• Install high-quality, weather-resistant solar panels designed to withstand various environmental conditions.
• Implement a robust mounting system to secure panels against strong winds.
• Regular maintenance and cleaning to ensure optimal performance, especially after storms or during pollen seasons.
• Consider adding a battery storage system to store excess energy for use during periods of lower production.

Overall, Winston-Salem's location provides a favorable environment for solar energy generation, with the potential for significant energy production throughout the year, particularly during the warmer months.

Solar output per kW of installed solar PV by season in Winston-Salem

Seasonal solar PV output for Latitude: 36.0395, Longitude: -80.1896 (Winston-Salem, 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 Winston-Salem, United States

To maximize your solar PV system's energy output in Winston-Salem, United States (Lat/Long 36.0395, -80.1896) 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 Winston-Salem, 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 Winston-Salem, 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	29° 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 Winston-Salem, 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 Winston-Salem, 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 Winston-Salem, United States

Winston-Salem, located in the Piedmont region of North Carolina, is characterized by a diverse and gently rolling topography. The city itself is situated in a shallow basin surrounded by higher terrain, creating a picturesque landscape that transitions from urban areas to more rural settings. To the west of Winston-Salem, the land gradually rises towards the foothills of the Blue Ridge Mountains. This area features a series of low hills and ridges, with elevations gradually increasing as you move further west. The terrain becomes more rugged and forested, with steeper slopes and deeper valleys. To the east and south of the city, the topography is generally flatter, with gentle slopes and broader valleys. This area is part of the larger Piedmont Plateau, which extends across much of central North Carolina. The landscape here is a mix of open fields, wooded areas, and scattered residential developments.

Potential Areas for Large-Scale Solar PV

When considering areas near Winston-Salem that would be most suited for large-scale solar photovoltaic (PV) installations, several factors come into play. The ideal locations would have relatively flat or gently sloping terrain, good sun exposure, and proximity to existing infrastructure. The areas to the east and south of Winston-Salem offer the most promise for large-scale solar PV projects. These regions have more open, level land that would require less grading and preparation for solar panel installation. The flatter topography also means fewer obstacles that could cast shadows on the panels, maximizing their exposure to sunlight throughout the day. Specifically, the rural areas in Forsyth County (where Winston-Salem is located) and neighboring counties like Davidson, Davie, and Yadkin could provide suitable locations for solar farms. These areas often have large tracts of agricultural land or former tobacco fields that could be repurposed for solar energy production. It's worth noting that while the western areas near Winston-Salem offer scenic beauty, they are less ideal for large-scale solar installations due to their more varied topography and increased forest cover. The hilly terrain and potential for shading from trees and landforms make these areas less efficient for solar energy production on a large scale. When selecting specific sites for solar PV projects, developers would need to conduct detailed assessments of local zoning regulations, grid connectivity, and environmental impact. However, the generally favorable topography and climate of the region surrounding Winston-Salem make it a promising area for expanding solar energy production in North Carolina.
