The article presents the methodology of testing the resistance of solar collectors to impacts caused by hail, based on the provisions of the applicable national standard PN-EN ISO 9806. Selected aspects of the two research methods proposed in the standard, using ice or steel balls to simulate hail impacts, are discussed. Both test methods were assessed, pointing to their advantages and disadvantages. At the same time, the problem of the lack of correlation between the forms of failure caused by ice and steel balls with the same impact energies was pointed out. In this context, reference was made to the provisions of the withdrawn national standard PN-EN 12975-2 and research studies.
