Be happy: here in Germany they sell the KWh for 47cents and buy your solar KWh for 7 cents, end even that is not sure, most will just get nothing for their export, unless you go through a painful beaurocratic maze.
P.S. and on the top of it, you must pay
-a fixed Subscription Fee,
-a Network Fee,
-a Metering Fee,
-a Renewable Energy Levy
-a Network stabilization Levy
-an Electric Power Tax
-and -obviously- on everything + 19% VAT.
It's pretty similar here in Australia with a few exceptions.
i. Getting a feed-in tariff is not difficult but the buy/sell ratio is pretty much the same as yours. The typical sell rate here is ~US$ 0.03-0.06/kWh.
ii. Our "VAT" equivalent is 10%.
iii. All the extras you mention are built into the daily service fee and also the tariff, so the general customer doesn't really have transparency on those but they are all costs the retailer pays to the distributor, market operator and government and so get built into the retail price. None of the extra costs are added to the feed-in tariff, only to the import tariffs, which is primarily why there is such a big buy/sell price difference.
iv. But by far the biggest difference is the lower cost per kWh generated (~US$0.025/kWh over 15 years).
Grid-tied solar PV system professionally installed only cost ~US$ 0.5-0.6/W. When combined with our good solar irradiance it means the lifetime cost per generated kWh is pretty low. If your generation only costs 2.5c/kWh, then getting 3-6c/kW for excess exported to the grid is still OK. Far better to use it to replace a 20-50c/kWh import tariff instead, but if you cannot, then exporting excess still has some value.
All that means is households here only need replace a modest proportion (anything > 25-30%) of their imported energy needs with solar PV for it to make financial sense, even if they get very little for exported energy. That's usually pretty easy, more so if the home is occupied during the day. Water heating is low hanging fruit, while daytime space heating/cooling with heat pumps is next.
