Solar Heating with Flat-Plate Collectors in Residential Buildings: A Review

Abstract

The depletion of fossil energy reserves has intensified the interest in renewable energy sources, such as solar energy. Solar water heating represents an environmentally clean technology, with an abundant, permanent, renewable energy source that does not pollute or harm the ecosystem. In this context, the objective of the work was to revisit the theme of residential solar heating in relation to the use of flat-plate solar collectors. This study combined bibliometrics techniques and a systematic literature review. The results indicated that by considering the period from 1993 to 2020, we could find several publications revealing that the interest in this subject still remains high and current. Themes related to water heating and ambient cooling showed consistency in the publications, while studies focused on integrating solar thermal energy with other chemical processes, such as distillation or desalination, indicated that significant research is required in this area.
