In this paper, the results of research work on the development of an experimental device based on a parabolic solar concentrator. The concentrator dish was radiated by line parabolic solar imitator. The concentrator, have designed on the basic of satellite dish with different reflecting covers. Two tips of layers: aluminium plates and silver paint were used. In this work the focus of the parabolic concentrator was determined: is equal 0,56 m. The concentrator dish was radiated by line parabolic

The illumination parameter was measured by industrial luxmeter and at distance 2 m brightness of source is reduced to approximately 500 Lux. The brightness more the 500 lux concentrated on the focus area with square about 9 cm 2 . The distribution of brightness on cross section area was determined.
