A solar panel system with a battery is definitely a worthwhile investment, but unfortunately, with the absurd prices we have to pay here in the Netherlands, it's not affordable for everyone. And even if your energy bill could be lowered by consuming less, there's another bill on the other side; if you feed energy back into the grid, you have to pay for that too these days. They can't make it more attractive in the Netherlands, but they can make it more expensive and complicated.
