In many cases, solar panels do not have to be mounted on the roof. Urban houses, apartments, and commercial buildings in India are increasingly adopting a wall-mount solar panel system that allows for energy production while making efficient use of space.
What Are Wall-Mounted Solar Panels?
Wall-mount solar panels are panels that are mounted vertically on the southern wall of the building instead of being placed on the roof or on the ground. The panels may be installed parallel to the wall, slanted outwards for optimal energy production, or as a canopy overhang from the wall. Although mounted vertically, proper installation ensures maximum energy production throughout the year.
Wall mounting offers a brand-new area for mounting solar panels in urban settings where the roof space is either unavailable or insufficient. In India, where urbanisation rates are quite high and there are a lot of high-rise buildings, rooftop space is often unavailable for mounting solar panels.
How to Install Solar Panels on Walls in India
Installing wall-mounted solar panels requires specialised mounting hardware and careful planning. Here is a simple step-by-step overview:
Site Assessment: Identify south-facing walls with maximum sun exposure throughout the day. Avoid walls shaded by adjacent buildings or trees.
Mounting Structure: Use strong, corrosion-resistant aluminium rail systems designed for vertical installation. Unlike roof systems, wall-mounted panels fight gravity and require robust fastening to prevent displacement.
Panel Selection: Selecting panels that have been made keeping their installation on walls in mind is recommended. Flexi modules for walls in India, such as those recently introduced by Waaree, make an appropriate choice. The weight of these panels ranges from 30% to 70% of conventional glass panels, and they measure less than 3.5 mm. Besides, they can be attached to the surface without drilling or mounting at all.
Inverter Connection: Once mounted, panels are connected to a solar inverter that converts DC power generated by the panels into AC power for use in your home or business.
Do Wall-Mounted Panels Produce Less Energy?
Wall-mounted solar panels do produce less energy than optimally tilted roof panels during the summer months when the sun is high. However, they perform better in winter when the sun is lower in the sky, making them a strong complementary option alongside rooftop systems.
