Most solar-equipped homes in Hungary (and everywhere, really) use grid-tie inverters: they shut down the moment the grid goes down, supplying zero power even in the most sparkling midday sun. Switching to hybrid systems by adding (even minimal) local energy storage is the first step. The next is hooking up neighborhoods, villages, cities into microgrids of their own that communicate & intelligently share resources.
Residential wind is unrealistic and a permitting nightmare for the majority of individual households but on a shared level it could work and promises grid independence through 95% of the year!

Jonas Birgersson, a.k.a Broadband Jesus¹ talks about the self-sufficiency of the proof-of-concept EnergyNet² microgrid setup they have built in Lund, Sweden:
> Yeah, it will, but also it’s interesting because — 60% less on a year-to-year basis, but also six months of the year we won’t need any grid capacity at all. Even when it’s dark in Sweden, we don’t produce solar, if we have wind connected to this, the number of days when we need the grid goes down from six months to 14 days.
This absolutely tracks also in my experience in Estonia. You can get a bit more out of solar if you use vertical panels (=no snow build-up) and an oversize array - but even with that, when nights last 16-18 hours and even when the sun is "up" it's overcast, you really need wind. And days where it's bad solar AND bad wind are few and far between.
