I have had a set of panels on my roof for years, but I think going off grid is overrated unless it becomes drastically cheaper than being on grid.

Grid level batteries are going to be a more efficient way of using the same materials to achieve a particular level of supply. It's just at the moment there's a "competency arbitrage" where infrastructure is way slower than building it yourself.

I can attest that. I installed panels on my house, they are not enough to cover my electrocity needs, let alone gas (heating). Even if it would be enough to cover electricity needs, the cost was (upfront) more than the equivalent of the next 20 years in bills.

To be fair, many of the costs are because of high demand (artificial, because the gov. mandates it to be installed) and lots of work to be integrated in the national grid. But as things are right now, it not economically convenient (at least where I live) and for what I have heard, in other places is not much different.
