That is just regrettable. How people will adopt renewable energy when it is so expensive ?

Somewhat playing devils advocate here, but I think this will become normal the more solar PV there is.

There is also a certain logic behind such fees: in a typical grid-connected solar PV system you are only feeding into the network when you have excess power, which usually happens when other people also have excess power and as the result the prices for power have even temporarily become negative in countries with lots of PV installed. Thus from the perspective of the grid provider this feed in helps little and might even produce costs for them.

On the other hand they are providing a battery like service to grid connected PV owners, and storage is expensive as anyone knows that compared grid linked and off-grid solar PV solutions. Of course you are still paying for the power they provide, but with the solar PV in place it is pretty much guaranteed that you will only ask for power during evening peak loads, during which they also have to pay the most for the power they provide. So the mix-caluculation of a 24/7 same price that they offer to other customers doesn’t work for those with a solar PV system.

I think in general it would be good to have more grid-power contracts with different pricing per hour. This is already quite common for commercial contracts, but for home users it is still rare AFAIK. Then people would think about putting a timer on their washing machines etc. to only run during cheaper daytime hours and the power provided by solar PV could be utilized more efficiently by shaping demand.
