Working out of new technologies and the equipment for increase of efficiency of processes of photovoltaic conversion of a solar radiation is obviously important the factor of successful carrying out of these works. Results of works on creations of the new, non-standard equipment for studying of parameters of solar cells both in laboratory conditions, and in the conditions of their direct operation are described. Mode of operation of PV Thermal (PVT) modules which produce not only the electric power, but heat as well, differ considerably more temperature what negatively reflected in efficiency of solar cells. Works on studying of solar cells operation at such high temperatures to our best knowledge are not present, and creation of installation for these purposes demands the special approaches. We develop a technique of temperature measurement of PV cells and modules entirely composed of PV Thermal modules up to 700K. The results executed for the first time for this temperature range similar which is not described in the literature are submitted. For cells and modules tests special simulators of sunlight are usually used as results of natural tests are difficult for interpreting in connection with constant changes of level of solar radiation during measurements. We develop special installation which allows to carry out measurements parameters of PV part of the PV Thermal module as well as its thermal part synchronously with solar radiation measurements. The offered installation is simple and can be easily realized everywhere. The results of an estimation of thermal and PV parameters of PV Thermal module received for the first time in the course of its work on open air are resulted. Long term resource tests of solar cells and in particular modules usually fulfilled at installation of examinees objects in stationary position, without tracking the Sun. For a possibility to investigate characteristics both small (cells) and large (panels) objects the tracking system on two co-ordinates is developed. The system automatically is tracking movement of the Sun also provides an arrangement of a surface of examinees of objects normally to incident radiation. Efficiency of all elaborated approaches, devices and equipment are illustrated by results of experimental verifications.
