Sunways' Stefan Fischer, says: "In our cities there are more and more ways in which we can use façades to generate solar energy – the sky is literally our limit.

"Coloured and transparent solar cells from Sunways can either be integrated into shading elements or assume some of the roles of the building envelope when incorporated into solar modules. Even façade surfaces that are not ideally oriented still can be used in a way that makes economic sense nowadays thanks to falling system costs and improved links with other green technologies such as heat pumps."

BIPV solar solutions also open up possibilities in terms of architectural aesthetics, as demonstrated by Sunways' silicon solar cells in different colours, shapes and transparency grades.
