This Thesis project is a part of the research works in Solar industry. ABSOLICON Solar Concentrator AB has been invented and started production of the prospective solar concentrated system Absolicon X10. The aims of this Thesis project are designing, assembling, calibrating and putting in operation the automatic measurement system intended to evaluate the distribution of density of the solar radiation in focal line of the concentrated parabolic reflectors and to measure the radiation from the artificial source of light as calibration testing tool. On the basis of the requirements of the company administration and needs the designing process of the concentrated reflectors the operation conditions for the Sun walker were formulated. At the first step, the complex design of the whole system was made and division on the parts was defined. After the preliminary conducted simulations the function and operation conditions of the all parts were formulated. At the next steps, the detailed design of all the parts was conducted. Most components were ordered from respective companies. Some of the mechanical components were made in the workshop of the company. All parts of the Sun walker were assembled and tested. Software part, which controls the Sun walker work and conducts measurements of the solar irradiation, was created on the LabVIEW basis. To tune and test software part the special simulator was designed and assembled. When all parts were assembled in the complete system, the Sun walker was tested, calibrated and tuned.
