The 20% PoS distribution is related to 3/4 of the total distribution is thru PoS (50m PoW, 150m PoS), depending on whats been mined so far with SolarCoin, could be done or something close since there will no longer be a dependence on PoW to maintain wallet syncing. 

For the most part it has been cheaper to mine other coins and buy SolarCoin.
