New Low-Emissivity the Long Lasting Paints for Cost-Effective Solar Collectors

Objective

The project aims to set up an improved sort of selective paints, with high photo-thermal performance in solar energy conversion, for coating solar collectors. They are expected to become widespread by being cost-effective and competitive with commercial technologies and making application processes easier (lower final costs at workshops). Solar thermal devices converting solar radiation into heat are mainly flat plate collectors.

Their most important and critical part is the absorber surface which, to maximize their output, must be spectrally selective (absorb as much solar energy as possible and have the lowest thermal looses). These surfaces are expensive and mainly based on the application of heavy metals (black chrome, black cobalt, black nickel) continuously under increasing environmental restrictions and, lately, titanium compounds. Moreover, covering is made in special facilities and panels are distributed to workshops where some lacks appear in their manufacture, such as the difficulty in ulterior assembling of previous covered pieces (welding problems, looses of performance) and sensitivity to manual manipulation.

Nowadays, some manufacturers use options based on painting the solar panels, presenting a substantial economical advantage but of restricted use due to drawbacks related to high emissivity-low energy efficiency and low durability in service life. To improve these drawbacks new coatings will provide hybrid-structured surfaces, at defined thickness ranges by control application methods and combining multi-layer systems to adjust the whole system performance.

The project considers the development of a technology applicable everywhere, especially suited for their implementation in Mediterranean countries (optimal solar conditions and demanding solar infrastructures in remote places (rural areas, villages...) and general buildings (hospitals, hotels).
