Scottsville, Virginia, located in the Northern Temperate Zone, offers 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 substantial differences throughout the year. Summer provides the strongest performance at 6.66 kWh per day per kW of installed solar capacity, making it the peak season for solar generation. Spring follows as the second-best season with 5.84 kWh per day per kW, offering nearly comparable output to summer months. Autumn sees a notable decline to 4.17 kWh per day per kW, while winter presents the most challenging conditions with only 2.59 kWh per day per kW. This winter output represents less than 40% of the summer peak, highlighting the significant seasonal challenge for consistent year-round energy production.Optimal Installation Configuration
For maximum year-round energy production at this Scottsville location, solar panels should be installed at a fixed tilt angle of 33 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's varying position throughout the year and weighting for solar irradiance potential.Local Environmental and Weather Factors
Several environmental and weather factors in central Virginia can impact solar energy production at this location:- Seasonal cloud cover and precipitation: Virginia experiences increased cloudiness during winter months and frequent thunderstorms in summer, which can reduce solar output during these periods
- Humidity and atmospheric haze: The region's humid subtropical climate can create atmospheric conditions that scatter sunlight and reduce panel efficiency
- Snow and ice accumulation: Winter weather can cause snow or ice to accumulate on panels, blocking sunlight entirely until cleared
- Deciduous tree coverage: Virginia's abundant deciduous forests mean that nearby trees may cast shadows on installations, particularly when leafed out from spring through fall
Preventative Measures for Enhanced Production
Several installation strategies can help maximize solar energy production despite these local challenges:- Proper site selection: Choose installation locations with minimal shading from trees, buildings, or other obstructions, particularly avoiding areas shaded during peak sun hours
- Panel spacing and mounting: Install panels with adequate spacing to prevent self-shading and use mounting systems that allow for easy snow removal access
- Anti-reflective coatings: Select panels with high-quality anti-reflective coatings to maximize light absorption during hazy or overcast conditions
- Regular maintenance scheduling: Plan for routine cleaning to remove accumulated dust, pollen, and debris, which can be significant in Virginia's humid environment
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 Scottsville, Virginia
Seasonal solar PV output for Latitude: 37.7987, Longitude: -78.4956 (Scottsville, Virginia, 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 33° South in Scottsville, Virginia, United States
To maximize your solar PV system's energy output in Scottsville, Virginia, United States (Lat/Long 37.7987, -78.4956) throughout the year, you should tilt your panels at an angle of 33° 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 Scottsville, Virginia, 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 Scottsville, Virginia, United States. As mentioned earlier, for fixed-panel solar PV installations, it is optimal to maintain a 33° South tilt angle throughout the year.
| Overall Best Summer Angle | Overall Best Autumn Angle | Overall Best Winter Angle | Overall Best Spring Angle |
|---|---|---|---|
| 22° South in Summer | 43° South in Autumn | 53° South in Winter | 31° 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.

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 Scottsville, Virginia, 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 Scottsville, Virginia, United States
Topographical Features Around Scottsville
Scottsville sits in the gently rolling landscape of central Virginia's Piedmont region, where the terrain transitions from the mountainous areas to the west toward the flatter coastal plains to the east. The town is positioned along the James River, which carves a meandering path through the countryside and creates a natural corridor of relatively flat bottomland surrounded by modest hills and ridges.
The elevation around Scottsville typically ranges from about 200 feet above sea level near the river to approximately 600 feet on the surrounding hilltops. These hills are generally rounded and weathered, characteristic of the ancient Piedmont geology, rather than steep or dramatic. The landscape features a mix of agricultural fields, pastureland, and forested areas, with many cleared areas that have been used for farming for generations.
The James River valley itself provides some of the flattest terrain in the immediate area, though periodic flooding has historically been a concern in the lowest-lying areas near the water. Moving away from the river, the land gradually rises through a series of gentle slopes and broader ridge systems that extend both north and south of the town.
Optimal Areas for Large-Scale Solar Development
The most suitable locations for large-scale solar photovoltaic installations around Scottsville would be the elevated plateau areas and broad ridge tops that rise above the immediate river valley. These areas typically offer several advantages including more consistent terrain gradients, reduced flood risk, and often fewer competing land uses compared to the prime agricultural bottomlands near the James River.
The rolling hills to the north and south of Scottsville present particularly promising opportunities, as many of these areas feature relatively gentle slopes that can accommodate solar arrays without extensive grading or site preparation. The southern-facing slopes of these ridges would be especially valuable, as they naturally provide optimal orientation for solar panel installations throughout the year.
Areas of former agricultural land that have transitioned out of active farming represent another category of suitable sites. Many of these locations already have relatively clear terrain and may have existing road access and utility infrastructure nearby. The slightly elevated positions of many of these sites, typically 300 to 500 feet above sea level, help ensure good drainage and reduce concerns about seasonal flooding that might affect lower-lying areas.
The broader plateaus and ridge systems extending east and west of Scottsville also offer potential for solar development, particularly where the terrain levels out into more expansive flat or gently rolling areas. These locations often provide the space needed for utility-scale solar installations while maintaining reasonable access to existing electrical transmission infrastructure that serves the region.
