sufficient for providing domestic hot water. They can continue to operate under cloudy conditions and should be linked to an insulated storage facility for continuity of supply. However, the installation cost is significantly higher than for flat bed collectors. (For more information see Smith, P.F. (2002) Sustainability at the Cutting Edge, Ch. 2, Architectural Press.)
