Using steam storage tanks instead of accumulators
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.

Few questions about steam storage tanks : r/factorio
Nope! Factorio pipes and storage tanks have extremely good insulation, it seems. My second thought was that they are to improve steam flow between turbine sections. Quite the opposite, actually. Fluid flow is based on % full, not absolute numbers. The greater the % difference, the faster the flow. A tank with 250 steam flows just as slowly as a ...
