FIELD: power engineering.
SUBSTANCE: system of concentrator photovoltatic plants comprises Sun-tracking concentrator photovoltaic plants arranged in the form of a rectangular lattice with a distance Xns between neighbouring concentrator photovoltaic plants in direction from the north to the south and the distance Xwe between neighbouring concentrator photovoltaic plants in direction from the west to the east, at the same time distances Xns and Xwe satisfy the following ratios simultaneously: Xns ≥ (a2 +b2)1/2, m; Xns ≥ 0.0105 · φ + 1.42, m; Xwe = B · Slp / Xns, m; where a - length of a light-perceiving surface of a concentrator photovoltaic plant, m; b - width of a light-perceiving surface of a concentrator photovoltaic plant, m; φ - geographic latitude of the place, °; B=0.0026·φ2-0.0584·φ+4.047 - non-dimensional coefficient for detection of the earth area required for placement of 1 m2 of the light-perceiving surface of the concentrator photovoltaic plant; Sne - area of the light-perceiving surface of the concentrator photovoltaic plant, m2; and the earth area Sse for placement of the system of concentrator photovoltaic plants meets the following ratio: Sse=N·B·Slp, m2; where: N - number of concentrator photovoltaic plants, pcs.
EFFECT: system makes it possible to provide for maximum efficiency of conversion of arriving radiation into power with permissible losses of energy as a result of shading, and minimum area of earth surface required for placement of a system of concentrator photoelectric plants.
