Alexander, North Carolina, located in the Northern Temperate Zone, presents a moderately favorable environment for solar PV energy generation throughout the year. The location's seasonal solar output varies significantly, with summer being the most productive period and winter the least.

Seasonal Solar Performance

Summer stands out as the peak season for solar energy production, with an impressive 6.42 kWh per day for each kilowatt of installed solar capacity. Spring follows closely behind, generating 5.77 kWh/day. Autumn sees a noticeable decrease to 4.36 kWh/day, while winter experiences the lowest output at 2.82 kWh/day.

These figures indicate that Alexander enjoys robust solar potential during the warmer months, particularly from late spring through early fall. However, the significant drop in winter production suggests that supplementary energy sources might be necessary during the colder months to maintain consistent power supply.

Optimal Panel Installation

To maximize year-round solar energy production in Alexander, fixed solar panels should be installed at a tilt angle of 31 degrees facing south. This orientation allows for optimal sunlight capture across all seasons, balancing the high summer sun and the lower winter sun angles.

Environmental Considerations

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

1. Tree coverage: The area's lush vegetation could potentially shade solar panels, reducing their efficiency. Careful site selection and tree trimming may be necessary.
2. Weather patterns: The region experiences occasional severe weather, including thunderstorms and heavy rainfall, which could temporarily reduce solar output.

To mitigate these factors, installers should conduct thorough site assessments, ensuring panels are placed in areas with minimal shading. Additionally, using high-quality, weather-resistant panels and robust mounting systems can help maintain performance during adverse weather conditions.

Overall, Alexander, North Carolina offers a good location for solar PV energy generation, with strong potential during warmer months and adequate output year-round when properly optimized.

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

Seasonal solar PV output for Latitude: 35.7025, Longitude: -82.6188 (Alexander, 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 Alexander, United States

To maximize your solar PV system's energy output in Alexander, United States (Lat/Long 35.7025, -82.6188) 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 Alexander, 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 Alexander, 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
19° 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 Alexander, 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 Alexander, 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 Alexander, United States

The topography around Alexander, United States, located at latitude 35.7025 and longitude -82.6188, is characterized by its rugged and mountainous terrain. This area is situated in the western part of North Carolina, nestled within the Appalachian Mountain range. The landscape is dominated by steep slopes, rolling hills, and deep valleys, creating a picturesque and challenging environment. The region surrounding Alexander is part of the Blue Ridge Mountains, a subset of the larger Appalachian system. These mountains are known for their distinctive bluish haze when viewed from a distance, caused by natural emissions from the dense forests that cover much of the area. The elevation in this region varies significantly, with some peaks reaching several thousand feet above sea level. Rivers and streams are common features in the topography around Alexander, carving their way through the mountainous terrain and creating scenic gorges and waterfalls. The French Broad River, one of the oldest rivers in North America, flows near Alexander and has played a significant role in shaping the local landscape over millions of years.

Potential Areas for Large-Scale Solar PV

When considering areas nearby that would be most suited to large-scale solar photovoltaic (PV) installations, there are some challenges due to the mountainous terrain. However, certain locations may still be viable for solar energy projects: Flatter areas in river valleys or on plateaus would be the most suitable for large-scale solar PV installations. These locations offer more level ground, which is essential for the efficient placement of solar panels. Some of these areas may be found along the French Broad River valley or on the less steep portions of the surrounding hills. South-facing slopes in the region could also be potential sites for solar farms. While the terrain is challenging, these slopes receive more direct sunlight throughout the day, which could increase the efficiency of solar panels. However, careful engineering and design would be necessary to overcome the difficulties posed by the uneven terrain. It's important to note that the heavily forested nature of the region may require some clearing to create suitable spaces for solar installations. This would need to be balanced with environmental considerations and local regulations. Additionally, any large-scale solar project in this area would need to take into account the potential for shading from the surrounding mountains, which could impact the overall efficiency of the installation. While the topography around Alexander presents challenges for large-scale solar PV projects, innovative approaches and careful site selection could still make solar energy viable in this beautiful mountainous region.
