Abstract: This paper presents the results of the investigation of the effect of chemical coatings on the performance of solar collector plates. The three metallic plates used are aluminium, copper and iron sheets. Their absorptance and reflectance before and after the application of chemical coatings were investigated. Two types of chemicals were used: cupric nitrate (Cu(NO3)2·3H2O) for CuO coating, and carbon black for carbon black coating. The methods used in these coatings are spraying pyrolysis and painting methods, respectively. The results show increases in solar absorptance and decreases in reflectance with chemical coatings.
