Both these technologies use the sun’s energy to provide a source of sustainable power, are easy to retrofit (either as part of a sustainable refurbishment or to install in new buildings), and provide an income for the building occupiers. The presentation covers the main types of solar thermal and PV systems on the market and considers design, installation and maintenance issues to ensure that architects can specify the most efficient solution for any situation and that the systems perform at their optimum. It also looks at Govt support from the Renewable Heat Incentive and Feed-in Tariff to demonstrate payback periods.
