The article deals with measuring results of the solar radiation on stationary placed and tracking the sun surfaces, as well as air temperature and relative humidity from 01 April until 26 November 2005 in Ulbroka, Riga region (Latvia). The measurements were carried out by the device of a special constructions MD-4 developed at the Research Institute of Agricultural Machinery in 2004. For the data acquisition two thermo-batteries were used. The obtained data into computer memory were collected and after analyzed. It was stated that during the period of measuring (227 days) the thermo-battery tracking the sun has gathered by 1.4 times more heat energy than stationary located one. it means that in order to increase the hest yield solar collectors for domestic water heating have to track the sun.
