A dollar spent on renewables is still better spent on generating capacity, most places, even if peak power is given away part of every day.
Storage cost is falling even faster than solar ever did, so waiting until next year gets you more storage for the price. Also, transmission to local storage is low-loss, so you don't strictly need to be responsible for both. Finally, demand for peak generation will only increase as synthesis (H2, NH3, etc.) capacity comes online. Stockpiled H2 and NH3 will prove entirely adequate as bulk storage despite their low round-trip efficiency, given just a few hours of a better alternative, and anyway that efficiency will only ever improve.
The main attraction of H2 and NH3 storage, despite current lossiness, is that the equipment can operate even after the tanks are full, because there will be unlimited demand for both, for a long time. That is, anytime you are not actually drawing down stored energy, the expensive synthesis equipment can be producing to sell, producing revenue. Similarly for liquified air (N2, really).
