We developed a calculating-experimental procedure for the forecast of electrical power losses of spacecraft silicon solar arrays during long-term operation in circular orbits within the Earth’s polar ionosphere and magnetosphere. Power losses of solar arrays due to the effect of individual factors of the environment around a spacecraft are determined. It is shown that integral values for power losses of solar arrays, with consideration for the effect of individual factors of the environment around a spacecraft, agree with satellite measurement results.
