Concord, Virginia is a reasonably good location for solar energy generation, though it experiences typical seasonal variations found throughout the Northern Temperate Zone. The solar output data shows this location can produce varying amounts of electricity depending on the time of year.

Seasonal Solar Production Patterns

Summer provides the highest solar energy output 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 excellent solar production as days lengthen and weather improves. Autumn sees a notable decline to 4.17 kWh per day per kW as the sun's angle decreases and weather patterns change. Winter represents the lowest production period at just 2.59 kWh per day per kW, which is typical for locations in Virginia's latitude.

Optimal Panel Installation

For maximum year-round energy production at this Concord location, solar panels should be installed at a fixed tilt angle of 32 degrees facing south. This angle has been calculated to optimize total annual solar output by accounting for the sun's changing position throughout the year and weighting the angles based on actual solar irradiance potential.

Local Factors That May Impact Solar Production

Several environmental and weather factors in the Concord, Virginia area could potentially reduce solar energy output:

• Frequent cloud cover and overcast skies, particularly during autumn and winter months
• Snow accumulation on panels during winter storms
• High humidity levels that can create haze and reduce solar irradiance
• Tree coverage and vegetation growth that may create shading issues
• Dust, pollen, and organic debris accumulation on panel surfaces

Preventative Measures for Better Performance

To maximize solar energy production despite these challenges, several installation and maintenance strategies can be implemented. Proper site selection involves choosing locations with minimal shading from trees, buildings, or other obstructions, and conducting shading analysis throughout different times of day and seasons. Panel positioning should allow for adequate spacing between rows to prevent self-shading, while ensuring the 32-degree south-facing tilt is maintained. Installing panels with sufficient ground clearance helps prevent snow buildup and allows for better air circulation. Regular maintenance becomes crucial in this environment. This includes periodic cleaning to remove pollen, dust, and organic debris, especially during spring and fall. Snow removal systems or steep panel angles can help snow slide off naturally during winter months. Monitoring systems should be installed to track performance and quickly identify any issues that might reduce output. This allows for prompt maintenance when production drops unexpectedly due to soiling, shading, or equipment problems.

Solar output per kW of installed solar PV by season in Concord, Virginia

Seasonal solar PV output for Latitude: 37.3368, Longitude: -78.9772 (Concord, 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 32° South in Concord, Virginia, United States

To maximize your solar PV system's energy output in Concord, Virginia, United States (Lat/Long 37.3368, -78.9772) 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 Concord, 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 Concord, Virginia, 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
21° South in Summer	42° South in Autumn	53° South in Winter	30° 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.

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 Concord, Virginia, United States

Topography Around Concord, Virginia

The area surrounding Concord, Virginia is characterized by gently rolling hills and undulating terrain typical of the Piedmont region. This location sits in the transition zone between the Blue Ridge Mountains to the west and the flatter Coastal Plain to the east. The landscape features moderate elevation changes with hills ranging from approximately 400 to 800 feet above sea level, creating a series of ridges and valleys that flow in a generally northeast-southwest direction. The terrain consists primarily of weathered crystalline bedrock covered by clay-rich soils that have developed over millions of years of erosion. Stream valleys cut through the landscape, creating natural drainage patterns that flow toward the James River system. These waterways have carved gentle slopes and created areas of both well-drained uplands and moister bottomlands.

Forest Cover and Land Use Patterns

Much of the region remains forested with mixed hardwood and pine stands, though agricultural activities have historically shaped the landscape. Open fields, pastures, and farmland are interspersed throughout the area, particularly on the more level ridge tops and gentler slopes. The combination of wooded areas and cleared land creates a patchwork pattern typical of rural Virginia. The existing infrastructure includes country roads that generally follow the natural contours of the land, connecting small communities and individual properties. Power transmission lines already traverse portions of the region, which could be advantageous for future energy projects requiring grid connections.

Optimal Areas for Large-Scale Solar Development

The most suitable locations for large-scale solar photovoltaic installations would be the relatively flat to gently sloping ridge tops and plateau areas that offer several key advantages. These elevated areas typically have fewer trees and more open agricultural land, reducing the need for extensive clearing operations. The ridge tops also tend to have better exposure to prevailing winds, which helps keep solar panels cooler and operating more efficiently. South-facing slopes with gradients of less than 15 degrees would be particularly well-suited for solar development, as they can be easily accessed by construction equipment and maintenance vehicles. Areas that are currently used for hay production or cattle grazing often represent ideal candidates, as the land is already cleared and relatively level. The broader valley floors, while flatter, may be less desirable due to potential drainage issues during heavy rainfall and the tendency for morning fog to linger in low-lying areas. Additionally, many valley bottoms contain streams or wetlands that would require environmental considerations and setbacks.

Infrastructure and Access Considerations

Properties with existing road access and proximity to electrical transmission infrastructure would be most practical for development. The region's network of rural roads provides reasonable access to many potential sites, though some locations might require upgrades to handle heavy construction equipment and ongoing maintenance needs. Areas within reasonable distance of existing electrical substations or major transmission lines would minimize the costs and complexity of connecting solar installations to the electrical grid. The relatively stable geology of the Piedmont region, with its crystalline bedrock foundation, provides good support for solar mounting systems and access roads.
