@lin11c @Gustodon the only problem is, that in temperate climate zone, you have winter. During winter, the production goes as low as 10% and only for few hours per day.

Cloudy days and nights are mostly ok during summer, when the batteries can recharge only after few hours of sunlight.

This means, that we still need some backup sources during winter. And this is the only issue, because scalable long term accumulation is still not easy.

@lin11c @Gustodon unlike plastic crap, with batteries, the obsolescence is not really planned. Of course, the best available technology may not be available, for example because of stockpiles of old stuff or licensing issues, but mostly I beleive it is just really because existing level of technology.

In most of temperate climate zone, you can get energy autonomy with solar panels and battery for 8 months per year, but the winter season would be really tricky, even when burning wood for heating. But selling excess energy to grid and buying it during winter can be way to go. The regulations required for doing this are slowly getting better.

@lin11c almost everybody likes almost anything more, than nuclear. But natural gas is so cheap, that possible accumulation solutions are not competitive.

Another solution would be huge seasonal differences in prices of electricity, which would force shutting down of certain industrial processes during winter. But it may be problem to protect households from high prices during winter. This is why general public will always call for cheap natural gas, just like bread and games in Rome.

Small scale, off-the-grid seasonal storage is something almost everybody dreams about. Besides free home energy it would mean also free charging of electric cars and much more...
