Yes.
We are in the midst of a shift - i think early adopters were tempted by high feed-in-tariffs that are no longer there.
There is still a feed-in pay back, of course, but it's not particularly generous - the real deal now is that you are self-sufficient, and theoretically cost neutral at least.
The theoretical part will come if and when we start to see failures/inefficiencies in the hardware - which is something we cannot accurately calculate yet.
Before we all suck each other's dicks, it's probably worth giving at least some thought as to where the rare earth elements in our batteries came from?
Unfortunately we're in a lesser of two evils situation, the oil giants or the rare earth mineral miners. If I didn't have batteries I'd draw more from the grid, which means more fossil fuels burnt and me still being reliant on the energy companies. It actually means I'd be helping them, as they get my solar really cheap to resell and then they charge me loads for what I take off them, effectively handing them a large profit for my outlay. I don't know what the solution is but I don't think continuing to burn fossil fuels is it, and unfortunately lion is about our best option right now.
As for the original incentives, if you had the money back then you'd be getting 60p/kWh generated right now! As always though the ones that can afford it anyway got the best deals. That said the flux tariff seems to be working for us so far, only been 2 weeks but we appear to have a negative bill for that period before standing charge. Not sure about after, our bill is a few days late due to the kings new hat. If we can maintain a negative bill through the summer and go back onto an EV tariff for the winter we should be able to get our bill down to a few hundred per year at most. We want a year on solar before we look at the heating, the plan is still to move some heating to electric to allow balancing between that and gas depending on the situation, but also to allow much simpler heating deployment in a few areas currently lacking.
