@waldoj @simon_brooke they will have to clamp down on this sooner rather than later, feeding electricity back into the grid in such a way is a disaster in waiting for grid stability, cheap inverters aside, domestic solar generally only provides electricity back to the grid when the grid doesn’t needed it, which leads to overloading it, so the ‘buy-back’ must be controlled centrally by the grid. 500k installations in the context of Germany is nothing, and it doesn’t scale.

@simon_brooke @waldoj not what this is though, is it? This is just people plugging random inverters into the mains socket. Rooftop solar is of course workable, and one of the better options, but not this way. But perhaps it demonstrates that the official rooftop installations are priced with huge profit markups.
