The problem of electric power supply of spacecraft fail-safety is formulated. A method for estimation of risky degree of non-supply by necessary power level is developed. The application of this method to the case of solar array pointing failure is shown. The efficiency of additional putting into operation of outward control commands for solar array pointing is numerally confirmed.
