The UK's stated policy aims at the start of the feed-in tariff scheme in 2010 were twofold: to create more demand for modules in order to ramp up production and bring their unit price down; and to increase public awareness of renewable energy. In 2011 both these aims succeeded beyond expectations. As a result, the tariff rate has been reduced from 43p to 16p per kWh for common domestic installations. Yet the costs of modules have also almost halved (although the balance of system costs have not).
