Reply to comment by improbablyatthegame in Rooftop solar trumps all fossil fuels as renewables smash more records on main grid [Australia] by EnergyTransitionNews

For an amount comparable to 2.2kWh!? That's insane!

That's about 10x the size of mine, so actually not too surprised it's 10x the price!

To have that much solar power on my house in the UK I think I would need to register as a power station, if I wanted to also connect and input to the grid! (Don't hold me to that, it's just anything up to 5kW has a really simplifying process and no planning permissions or needed or anything).

In the UK average houses only really need 2-3kW system, which would basically meet all needs in the summer but not really touch the sides of usage in winter - we get so little sunlight in the winter it's not even worth trying.

It's very, very rare for a residential property to have above a 5kW system.

But then, we don't really use cooling and we tend to use natural gas for heating. So while we only use 10-15kwH of electricity per day, we use a lot more in natural gas for heating over the winter.
