When it's bought back from you, they only pay for the generation part which makes sense in my opinion. Now where that price point is, I don't know! (25%? 50%? no idea)
It seems the smart meter issue is almost unrelated though. Where I am (UK, potentially where you are too as it looks like a similar issue), the old feed-in tariff subsidised the energy _generated_ by a system, regardless of if you used the energy yourself or exported the energy. That's great to kick-start an economy but doesn't scale at a national level.
I understand they are trying to push to pay for what is exported by houses only. I'm a bit sad to see the old subvention gone as it made solar panel uneconomical in lots of situations, and there's a lot to say about timing, but in principle I think it's sound reasoning.
Meanwhile, I live in a country where on the one side they're pushing for and subsidizing solar energy, but at the same side they're forcing people to change their meters so that the energy companies can pay you less for power you feed back to the grid; with a 'dumb' meter, it was an even exchange, meaning that you only paid for the power you did not produce yourself. With the new system, you (I think?) only get 25% of the amount you sell, compared to the amount you pay.
