Solar panels, FIT etc


I’m new to Bulb and have just had a 4KW PV system installed yesterday. I know that the FIT no longer exists but I am told by my installer that there are new rules apparently coming out in January 2020 with regards to a new type of FIT. Could Bulb shed some light on this ?

Obviously I have spent a lot of money on my solar system and giving back to the grid my surplus electricity I produce and not getting paid anything for it just feels wrong.

I am going to be installing a Tesla Powerwall 2 next year once money has recovered a little but it would be nice to get something back on my surplus in the meantime.
