Solar PV Analysis of East Flat Rock, United States
East Flat Rock, North Carolina, located in the Northern Temperate Zone, offers a moderately favorable location for generating energy via solar photovoltaic (PV) systems year-round. The seasonal variations in solar energy production at this location provide insights into its potential for solar power generation.
Seasonal Solar Energy Production
Solar energy production in East Flat Rock varies significantly throughout the year: • Summer: 6.42 kWh/day per kW installed • Spring: 5.80 kWh/day per kW installed • Autumn: 4.41 kWh/day per kW installed • Winter: 2.88 kWh/day per kW installed
The most ideal times for solar energy generation are during the summer months, followed closely by spring. These seasons offer longer daylight hours and more direct sunlight, resulting in higher energy production. Autumn sees a moderate decrease in output, while winter experiences the lowest production due to shorter days and less intense sunlight.
Optimal Panel Tilt Angle
For fixed panel installations in East Flat Rock, 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 the location's latitude and the Earth's elliptical orbit.
Environmental and Weather Factors
While East Flat Rock generally offers good conditions for solar energy production, there are some factors that could potentially impact solar panel efficiency:
1. Cloud cover: The region experiences an average of 212 sunny days per year, which is slightly above the US average. However, cloudy days can reduce solar output.
2. Precipitation: With an average of 52 inches of rain annually, occasional heavy rainfall could temporarily decrease panel efficiency.
3. Tree coverage: The surrounding area has significant vegetation, which could potentially cast shadows on solar panels if not properly accounted for during installation.
Preventative Measures
To mitigate these factors and ensure optimal energy production, consider the following measures:
1. Conduct a thorough site assessment to identify potential shading issues from trees or structures.
2. Install panels at the recommended 31-degree tilt to maximize year-round production.
3. Use high-quality, weather-resistant panels that perform well in various conditions.
4. Implement a regular cleaning and maintenance schedule to keep panels free from debris and operating at peak efficiency.
By taking these steps, solar PV systems in East Flat Rock can effectively harness the available solar energy throughout the year, despite some seasonal variations and environmental factors.
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 East Flat Rock
Seasonal solar PV output for Latitude: 35.2799, Longitude: -82.4186 (East Flat Rock, 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 East Flat Rock, United States
To maximize your solar PV system's energy output in East Flat Rock, United States (Lat/Long 35.2799, -82.4186) 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 East Flat Rock, 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 East Flat Rock, 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 | 40° South in Autumn | 50° 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 East Flat Rock, 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 East Flat Rock, United States.
Our calculation method
- Solar Position:
We determine the Sun's position on the Winter solstice using the location's latitude and solar declination. - Shadow Projection:
We calculate the shadow length cast by panels using trigonometry, considering panel tilt and the Sun's elevation angle. - 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 East Flat Rock, United States
The topography around East Flat Rock, North Carolina, is characterized by a mix of gently rolling hills and relatively flat areas, as its name suggests. The region is situated in the foothills of the Blue Ridge Mountains, which means that while it's not as mountainous as areas further west, it still has some elevation changes and undulating terrain.
To the east of East Flat Rock, the land becomes gradually flatter as it transitions towards the Piedmont region of North Carolina. This area features more open spaces and gentler slopes. To the west and northwest, the terrain becomes more rugged and mountainous as it approaches the Blue Ridge Mountains proper.
The immediate vicinity of East Flat Rock includes some small hills and valleys, with elevations ranging from about 2,100 to 2,300 feet above sea level. There are also several creeks and small rivers that wind through the landscape, creating natural drainage patterns and occasional floodplains.
For large-scale solar PV installations, the areas most suited would likely be found to the east and southeast of East Flat Rock. These regions tend to have:
- Flatter terrain, which is easier and less expensive to develop
- Fewer forested areas, meaning less land clearing would be required
- More open spaces that could accommodate large arrays of solar panels
- Generally good sun exposure due to the less mountainous landscape
Specific locations that might be suitable could include areas near the Henderson County line, heading towards Hendersonville and Fletcher. These places often have larger tracts of agricultural or unused land that could potentially be repurposed for solar energy production.
However, it's important to note that any large-scale solar project would require detailed site surveys, environmental impact assessments, and compliance with local zoning laws and regulations. The suitability of a particular site would also depend on factors such as proximity to electrical infrastructure, local energy demand, and community acceptance.
