Abstract

The development of an integrated technology of solar energy building materials; a flat-plate solar collector was designed and manufactured. The absorption plates and the outer frames of the solar collector are made of corrosion-resistant aluminum alloy. The solar collector has a thinner cross-sectional structure, small mass, functional integrity, and rigidity. Thus, it is convenient for the installation, removal, maintenance, and replacement of the collectors. We have used excellent composite coating materials to absorb the higher solar energies and increase the absorption rate of the solar panels. From the test results, the emissivity of the solar energy absorption film of the collector core plate was very high; the average thermal collector efficiency of building material-integrated collectors still reaches more than 50%. We conducted the experimental results that the solar collector materials for construction have higher thermal efficiency than the collector installed on the platform. In future improvements, the glass panels should be changed to 3mm thickness to reduce weight and increase shortwave transmission. The absorbing film also needs to be improved to improve the thermal efficiency of the solar panel. This paper mainly introduces the collector design and thermal performance.
