Smart Voltaic Louvres - Solar shading systems are for commercial buildings to reduce energy consumption while generating solar energy.

Commercial buildings often have limited roof space for conventional solar panels. They also require shading devices for protection against the harsh summer sun. The Solution generates solar energy, and it saves energy by reducing heating, cooling, and artificial lighting needs in commercial buildings. It is the Internet of Things (IoT) enabled and uses a sun-tracking algorithm with inputs from sensors and other data to optimize louvre slat position with minimum to no manual involvement. This allows louvres to be controlled individually, collectively, or per façade, while the stacking option can be utilised to maximise daylight, ventilation or to allow for window maintenance. It is a turn-key solution consisting of an array of double-sided photovoltaic slats installed in their frame onto a building façade, with dynamic slat control through the intelligent automation system. This is supported by an ongoing performance monitoring and maintenance service.
