Solar panels and solar tiles/shingles can be, and are increasingly available, in many shapes, forms and textures - all will impact on efficiency

Demand for low carbon and energy efficient housing will accelerate innovation with Building Integrated PV systems that are 'active roofs', rather than the conventional roofs with retrofitted solar systems of today: likely required more and more for of replacements and new builds.

Thank you for your helpful reply, Maurice, and the useful web links. The range of integrated designs for new buildings is very good. If we are to take seriously the usage of solar panels on existing buildings then retrofit panels will continue to play a major part. It is these retrofit panels whose design range is limited. You have demonstrated the potential.
