It turns out that domestic and community solar is already doing a lot more than folk realise, because in truth, it isn't metered, and it isn't monetised, but of course it should be, and has to be to stop inflation.
We can work out how much money should have been issued on it, by looking for the poiint when grid energy consumption began to diverge from population growth (In UK this was around 2005), extrapolate the actual energy usage expected by population growth. The difference between that, and utilities energy produced, is the actual energy product due to domestic and community solar. It is surprising how much money is involved. Issuing that money, as it will have to be done sooner or later to fix inflation, will result in the final incentive everyone needs to finish the job of going 100% solar by mostly domestic and community installations (They already comprise more than 90% of existing solar capacity in UK).
As for storage, it makes most sense for communities to use local microgrids backed up by hydrogen.
How to do that, in each installation is to put the solar electric directly to hydrogen generation by electrolyzer (See "Enapter" for example), which outputs to a tank, which outputs in turn to a 24/7 fuel cell, which supplies the microgrid community mains electricity. By nature, 24/7 availabiilty means that a constant excess of hydrogen will be produced. With all communities producing hydrogen, outlets with hydrogen to sell or exchange will become ubiquitous, literally on every street corner.
Converting EVs as necessary to HEV, by replacing the batteries in those with fuel cells then completes the distributed energy ecology, no more need for grids or centralised production of energy, and no more pollution.
A further bonus is automatic circulation of drinking water by way of the water exhausted from all operating fuel cells including in vehicles.
