Understanding Ground-Mounted Solar Systems
Unlike rooftop solar installations, ground-mounted solar arrays are exactly what they sound like—solar panels mounted on a framework anchored to the ground. This simple distinction creates numerous advantages, especially for properties in Western North Carolina and Upstate South Carolina.
Components of a Ground-Mounted System
A typical ground-mounted solar system consists of several key components:
Solar Panels: The photovoltaic modules that convert sunlight into electricity. For mountain properties, we typically recommend high-efficiency panels that maximize energy production even during shorter winter days or partially cloudy conditions.
Mounting Structure: The framework that supports the panels. In the Carolinas, we use heavy-duty mounting systems designed to withstand our region’s occasional high winds and varying weather conditions.
Foundation: Depending on your soil type and terrain, foundations may include concrete footings, ground screws, or driven piles. Our mountain terrain often requires customized foundation solutions.
Inverters: These devices convert the DC power generated by solar panels into AC power that your home or business can use. We typically install string inverters or microinverters, depending on your system design.
Wiring and Electrical Components: These connect your solar array to your home’s electrical system and, when appropriate, to the utility grid.
Types of Ground-Mounted Systems
In our decades of experience serving Western NC and Upstate SC, we’ve installed several types of ground-mounted systems:
Standard Fixed Ground Mounts: These systems are set at a fixed angle, typically optimized for your specific latitude. In our region, this usually means a southern orientation with a tilt angle between 25-35 degrees.
Pole Mounts: Elevated on a single pole, these systems can be ideal for smaller installations or properties with limited ground space. They’re also excellent for areas with occasional flooding concerns.
Tracking Systems: These advanced systems follow the sun’s movement throughout the day, maximizing energy production. While more expensive initially, they can generate 25-45% more energy than fixed systems, which can be particularly valuable in our region’s varying seasonal sunlight patterns.
Land Requirements & Site Assessment
Proper site assessment is crucial for ground-mounted solar installations, especially in the varied terrain of Western North Carolina and Upstate South Carolina. Our team conducts thorough evaluations to determine the viability of your property for solar energy production.
Space Considerations
For a typical residential ground-mounted system in our region, you’ll need approximately 100 square feet of usable land per kilowatt (kW) of solar capacity. A standard 10kW system—enough to power most homes in our area—requires roughly 1,000 square feet of land.
However, space requirements can vary based on several factors specific to mountain properties:
Terrain Type: Flat land is ideal, but our experienced team has developed specialized mounting solutions for sloped terrain common throughout Western NC and Upstate SC.
Panel Efficiency: Higher-efficiency panels require less space, which can be crucial for mountain properties with limited usable land.
System Design: The spacing between rows of panels affects total land requirements. In mountain areas with winter snow accumulation, we often recommend wider spacing to prevent snow shadowing.
Optimal Positioning
In the Carolinas, south-facing installations typically yield the best energy production. However, southeast and southwest orientations can still produce excellent results. During our site assessment, we’ll analyze:
Solar Access: We use specialized tools to measure potential shading throughout the year. In mountain areas, surrounding trees and hills can significantly impact production.
Seasonal Sun Patterns: Western NC and Upstate SC experience significant seasonal variations in sun angles and daylight hours. Our designs account for these regional patterns.
Microclimate Considerations: Local weather patterns, such as morning fog in valley locations or afternoon cloud buildup near certain mountain ranges, factor into our positioning recommendations.
Soil and Geological Assessment
Mountain properties often present unique geological challenges that must be addressed during planning:
Soil Composition: Rocky or clay-heavy soils common in our region may require specific foundation types.
Drainage Patterns: Proper water management is essential in our region’s rainfall-heavy climate to prevent erosion around your solar installation.
Geological Stability: Some mountain areas may have unique considerations regarding ground movement or stability that impact foundation design.
Benefits of Ground-Mounted Solar for Mountain Properties
After three decades of installing solar systems throughout Western North Carolina and Upstate South Carolina, we’ve seen firsthand why ground-mounted arrays often outperform rooftop installations in our mountain region.
Optimal Angle and Orientation
Many homes in our region have roofs that aren’t ideally oriented for solar production. With ground-mounted systems, we can position your array at the perfect angle and orientation regardless of your home’s design.
This optimization is particularly valuable in mountain settings where properties often have complex roof designs with multiple pitches, dormers, and orientations that complicate rooftop installations.
Easier Maintenance and Cleaning
Mountain environments present unique maintenance challenges for solar systems. Ground-mounted arrays offer significant advantages:
Accessibility: Panels are easily reached without climbing onto roofs, which is particularly important during our region’s winter months when rooftops can be hazardous.
Snow Removal: While our panels are designed to shed snow, ground-mounted systems allow for manual clearing when necessary after heavy snowfalls common in higher elevations.
Seasonal Adjustments: Some ground-mounted systems can be manually adjusted seasonally to optimize for summer and winter sun angles—a significant advantage in our region’s varying seasonal sunlight patterns.
Better Performance in Mountain Microclimates
The varied terrain of Western NC and Upstate SC creates unique microclimates that ground-mounted systems can better accommodate:
Cooling Efficiency: Ground-mounted panels typically operate at lower temperatures than roof-mounted systems because air circulates freely around them. In our region’s warm summers, this can translate to 10-15% better performance.
Adaptability to Site Conditions: We can precisely position ground-mounted arrays to minimize impact from morning valley fog or afternoon mountain shadows—conditions that frequently affect properties in our service area.
Future Expansion Capabilities
As energy needs grow or battery storage becomes more affordable, ground-mounted systems offer unparalleled flexibility:
Scalable Design: Systems can be designed with future expansion in mind, allowing for additional panels without structural limitations.
Integration with Newer Technologies: Ground-mounted arrays more easily accommodate emerging technologies like bifacial panels (which capture reflected light from the ground) or integrated storage solutions.
