Abstract. The response of the regular and distributing photovoltaic arrays to the action of a continuous powerful energy-carrying beam of various positions and sizes is discussed. The temperature variation of the segments of the array is taken into account depending on the intensity of the incident radiation. The modes of "hard" and "adaptive" thermal stabilization are considered - in the first case, all segments of the array are maintained at a constant temperature, in the second - a restriction on the maximum surface temperature is set, and the surface temperature profile in the quasi-stationary mode repeats the distribution of the energy-carrying intensity beam. The concept of generalized photoconversion efficiency is introduced when working with a beam whose dimensions are smaller than the linear dimensions of the array. A comparative analysis of the main photovoltaic characteristics of complete and truncated arrays optimized for the transformation of axisymmetric beams is presented.

Key words: photovoltaic array, temperature conditions, generalized efficiency, regular and distributive switching.
