Identification of the environmental impact from the use of different materials in domestic solar hot water systems
Martinopoulos, G.; Tsilingiridis, G.; Kyriakis, N. - In: Applied Energy 102 (2013) C, pp. 545-555
The use of different materials for the same solar system component (collector, water tank, etc.) affects both the efficiency and the amount of conventional energy substituted by the system and hence the overall environmental impact of a Domestic Solar Hot Water System (DSHWS). The net...
