Are wall mounted solar panels efficient?

Solar power is now being utilized as a diverse form of energy to harvest renewable sources, there are multiple ways to implement this in different environments. Among this, solar-powered panels that are mounted on the wall are an alternative to traditional rooftop or ground-based installations.

How do solar powered walls operate?<

These panels are connected to the vertical or sloping facades of buildings via specialized hardware or frames, such as those provided by SIC Solar. This method is particularly beneficial in urban areas, because the roof space or ground area is limited.


Factors that affect the effectiveness of solar-powered panels mounted on the wall.

  1. Wall orientation and tilt angle
    • The direction and slope of the walls have a significant impact on the amount of sunlight that the panels can receive.
    • The southern walls in the northern hemisphere are more beneficial because the sunlight is more abundant.
  2. Shading
    While the tilt angle can be adjusted to improve efficiency, Wall mounted systems offer less flexibility compared to roof setups. Shading, Wall mounted panels are more susceptible to shading from adjacent structures or the building itself, which can greatly affect power output. Choosing the best installation location is critical.
  3. Sunlight exposure
    Walls typically receive less direct sunlight than rooftops, especially at certain times of day, which results in a reduction in potential energy production depending on the design and orientation of the building.
  4. Seasonal change
    Wall mounted solar panels may perform better during periods of low sun, such as winter, but their efficiency may decrease during summer when the sun is higher.

Advantages of Wall mounted Solar Panels

  1. Space efficiency
    These panels are ideal for houses with limited roof or ground space, leveraging otherwise unused vertical surfaces.
  2. Architectural harmony
    Modern design can be seamlessly integrated with architectural aesthetics to create a modern appearance.
  3. Thermal efficiency
    Wall mounted solar panels can provide additional insulation, reducing heat transfer through the walls and increasing the energy efficiency of the building.
  4. Easy to maintain
    Wall mounted systems are usually more accessible than rooftop systems, thus simplifying cleaning and maintenance.

Challenges of Wall mounted Solar Panels

  1. Lower Energy Output
    The vertical position of Wall mounted panels means they typically receive less sunlight, especially when they are not facing south.
  2. Higher Risk of Shading
    Urban environments can cast a noticeable shadow on the panels, affecting their performance.
  3. Installation Complexity
    The structural requirements for installing panels on walls may require additional support, which increases costs.
  4. Angle Adjustments
    Compared to ground or roof systems, the adjustability of panel angles is limited, which may affect efficiency in some cases.
