The objective is to optimise the production of power while avoiding structural modifications and respecting the design of the building. For this reason, Onyx Solar® is an optimal choice, as it provides protection against the sun and generates power while improving the aesthetic appearance.
The panes forming the skylight are made of amorphous silicon with a L vision (20%) of semi-transparency degree. In addition to providing power in situ, these also provide natural lighting, ultraviolet and infrared radiation filter, and permanent protection against the climatic conditions of London.
Onyx Solar®‘s solution for this skylight generates a total of 3,700 kWh per year, making possible the powering of 210 lights and preventing the release of 2.5 tons of CO2 into the atmosphere. The total installed power is 34 kWp.
