Wall-Mounted Solar Panels: An Alternative Worth Considering
For some homeowners and businesses, installing traditional rooftop solar panels isn’t always an option. Whether it’s due to limited roof space, shading issues, or an unsuitable roof angle, these obstacles can make a standard solar installation impractical. But don’t worry—there’s another solution: wall-mounted solar panels.
Why Consider Wall-Mounted Solar Panels?
Wall-mounted solar panels are exactly what they sound like – solar PV panels installed vertically on the exterior wall of a building. While they are less common than roof installations, they offer a range of benefits for specific situations.
- Ideal Orientation: They perform best when mounted on a south-facing wall (in the Northern Hemisphere), where they can capture the most sunlight throughout the day.
- Space-Saving: Perfect for properties with limited or obstructed roof space. You can utilize unused wall surfaces to generate clean energy.
- Easier Maintenance: Because they’re mounted vertically and at a more accessible height, cleaning and maintenance are often more convenient compared to rooftop panels.
- Winter Performance: Surprisingly, vertical panels can outperform roof-mounted ones in winter months. Snow tends to slide off vertical panels more easily, and the lower angle of the sun in winter aligns well with the vertical positioning.
Considerations and Trade-Offs
While wall-mounted panels offer unique advantages, there are a few trade-offs to keep in mind:
- Reduced Efficiency: In general, wall-mounted systems may generate less energy annually than roof-mounted ones, especially in the summer when the sun is higher in the sky.
- Aesthetics: Depending on the design of your home or building, wall-mounted panels may be more visible, so aesthetics can be a factor for some.
- Mounting Requirements: Not all walls are suitable for supporting solar panels. The structural integrity of the wall, exposure to direct sunlight, and local building codes will need to be considered.
Is This the Right Option for You?
If your roof isn’t suitable for solar but you’re still eager to make a smart investment in solar, wall-mounted solar panels could be a practical alternative.
