My solar panels sit idle for most of the day. By 09h30 in the summer my batteries are fully charged, and it's only running my water heater (geyser). I estimate I have about 15kWh of excess that I should be able to export on a daily basis. But I can't, because "reasons". My father, with a much bigger system and an old school disk-style power meter is exporting close to 30kWh a day "illegally" once he's done charging his batteries and all that. And now they want to bring in additional fees and charges for selling to the grid, and they want to buy back at ridiculously discounted rates (1-10% of the buy-cost), which immediately makes it a non-starter for most. So even though 50-60% of all installed systems (my estimate) are ready and capable to export, nobody does, because "reasons".
