heal.abstract	An analysis is developed for the investigation of the transmittance–absorptance product (τα), and directional characteristics of plastic-film water-bag solar water-heaters, which are important for long-term system performance investigations. The analysis allows a complete comparative investigation of the effects of a large number of parameters, like water layer thickness, bottom solar absorptance, radiation transmission conditions and extinction properties of semi-transparent films, on the transmittance–absorptance product. Finally the comparative effect of diffuse and specular reflection and transmission assumption on the derived results is investigated. It is concluded that the use of low iron content glass panes may possibly lead to (τα) figures far in excess of 0.8 for new systems.	en
