Accumulator to solar ratio is 0.84 and accumulators store 5MJ. 0.84 * 5 = 4.2, so for every solar panel we need 4.2MJ of storage. One storage tank of 165 degree steam holds 750MJ / 4.2 = 178.571428571 solar panels per steam tank. For 1 solar panel you thus need 1 / 178.571428571 steam tanks or 0.056, same as your result.
