摘要：
The paper analyses the efficiency of three types of collectors: flat plate collectors and vacuum tube collectors (flow and heat pipe). Based on measured and calculated values, the influence of ambient temperature and solar radiation intensity on the change in efficiency was presented in the form of graphic dependencies. Using the recommendations of the standard for testing collectors, the values of the parameters of the quadratic polynomial as well as the change in efficiency as a function of the reduced temperature were found.
