Statistical evaluation of the characteristics of damaged solar panels of spacecraft

The change in the characteristics of a solar battery as result random abrupt properties individual cells, which occurred single or systematic impact adverse factors near-Earth outer space, is considered. choice calculation scheme for constructing model cell substantiated. For this situation, analytical mathematical models typical connections cells have been developed. Using developed models, current-voltage and volt-watt are analyzed case an decrease photocurrent with different probabilities. A statistical analysis damaged was carried out using simplified logical-analytical introduced circuit loss coefficient. Estimates values coefficient losses schemes connecting given. Keywords: cell, voltage characteristic, functioning model, battery.
