Windsor, North Carolina, located in the Northern Temperate Zone at coordinates 35.9985, -76.9461, presents a moderately favorable location for year-round solar energy generation, though with significant seasonal variations that potential solar installers should carefully consider.

Seasonal Solar Performance

The solar energy output at this location shows a typical temperate zone pattern with strong seasonal differences. Summer delivers the highest production at 6.34 kWh per day per kW of installed solar capacity, making it the peak generation season. Spring follows closely with 6.05 kWh per day per kW, indicating excellent solar conditions during these warmer months. Autumn production drops to 4.34 kWh per day per kW, representing a moderate decline as daylight hours shorten and sun angles become less favorable. Winter presents the most challenging period with only 2.76 kWh per day per kW, less than half the summer output. For optimal year-round energy capture at Windsor, fixed solar panels should be installed at a 32-degree tilt facing south. This angle maximizes total annual production by balancing the varying sun angles throughout the seasons.

Local Environmental Challenges

Several environmental factors in Windsor, North Carolina could potentially impact solar energy production:

• Coastal humidity and moisture: The proximity to the Albemarle Sound and Atlantic coastal region creates high humidity levels that can reduce solar panel efficiency and promote faster degradation of equipment
• Hurricane and severe weather risk: The location falls within the Atlantic hurricane corridor, presenting risks of high winds, heavy rain, and debris that could damage solar installations
• Agricultural dust and pollen: The surrounding rural agricultural area generates seasonal dust and heavy pollen loads that can accumulate on panel surfaces, reducing light transmission
• Frequent thunderstorms: Summer months bring regular thunderstorms with potential hail and lightning strikes

Protective Measures for Better Performance

To maximize solar energy production despite these challenges, several preventative measures should be implemented: Panel mounting systems should use hurricane-rated hardware designed to withstand wind speeds of at least 120 mph, with proper structural engineering assessments of roof loads. Installing panels with adequate ground clearance and secure anchoring helps protect against storm damage. Regular cleaning schedules become essential in this environment, particularly during high pollen seasons in spring and after dust storms. Installing panels at the recommended 32-degree tilt naturally helps with self-cleaning during rain events, but manual cleaning may still be necessary monthly during peak pollen periods. Choosing solar panels with anti-reflective coatings and hydrophobic surfaces can help minimize the impact of humidity and make cleaning more effective. Additionally, ensuring proper ventilation around panels helps combat efficiency losses from high humidity conditions. Lightning protection systems and proper electrical grounding become critical given the frequent thunderstorm activity. Installing surge protectors and following strict electrical codes helps protect the investment from lightning-related damage. Despite these environmental challenges, Windsor's solar potential remains reasonable for residential and commercial applications, particularly when proper installation techniques and maintenance schedules are followed to address the local climate conditions.

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

Seasonal solar PV output for Latitude: 35.9985, Longitude: -76.9461 (Windsor, 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 32° South in Windsor, North Carolina, United States

To maximize your solar PV system's energy output in Windsor, North Carolina, United States (Lat/Long 35.9985, -76.9461) throughout the year, you should tilt your panels at an angle of 32° 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 Windsor, 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 Windsor, North Carolina, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 32° 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 Windsor, 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 Windsor, North Carolina, United States

Windsor, North Carolina sits in the coastal plain region of the southeastern United States, characterized by relatively flat terrain with gentle rolling hills. The area lies at a low elevation, typically ranging from 10 to 50 feet above sea level, making it part of the broader Atlantic Coastal Plain that extends from New Jersey to Georgia. This topographical setting creates an ideal foundation for large-scale solar installations due to the minimal grading and site preparation required.

The landscape around Windsor features predominantly agricultural land interspersed with patches of mixed hardwood and pine forests. Open farmland dominates much of the surrounding countryside, with fields that have been cleared and maintained for decades of crop production. These cleared areas present excellent opportunities for solar development, as they already lack the tree cover that would otherwise create shading issues and require expensive clearing operations.

Terrain Characteristics

The terrain surrounding Windsor exhibits very gentle slopes, rarely exceeding 5% grade across most of the region. This minimal slope variation eliminates the need for extensive earthwork or terracing that would be required in more mountainous regions. The soil composition consists primarily of sandy loam and clay soils typical of the coastal plain, providing stable foundations for solar mounting systems while maintaining good drainage characteristics.

Water features in the area include the Cashie River, which flows northeast through the region, along with numerous smaller creeks and drainage ditches that serve the agricultural landscape. These waterways are generally well-contained within their channels and do not present significant flooding concerns for most elevated areas suitable for solar development.

Optimal Areas for Solar Development

The most promising locations for large-scale solar photovoltaic installations lie in the agricultural areas southwest and southeast of Windsor. These zones offer extensive tracts of relatively flat, open land with minimal existing infrastructure that would complicate development. The farmland in these directions typically features field sizes ranging from 50 to 200 acres, providing adequate space for utility-scale solar arrays.

Areas to the north and northeast of Windsor present additional opportunities, particularly where agricultural use has created large clearings in what was historically forested land. These locations benefit from existing road access developed to serve farming operations, reducing the infrastructure investment required for solar projects.

The terrain immediately east of Windsor toward the Albemarle Sound offers some potential, though developers would need to consider the slightly higher moisture levels and occasional wetland areas that characterize the transition zone between upland agricultural areas and the coastal marshes. However, the elevated portions of this region still provide viable options for solar development.

Forest areas, while abundant in the region, would be less suitable for solar development due to the environmental impact and cost associated with large-scale tree removal. The existing cleared agricultural land represents the most economically and environmentally sensible choice for solar installations, offering immediate access to suitable terrain without the complications of forest conversion.
