I live in NE Australia (~17"S) and our feed in tariff recently went up from ~6.6c to 9.3c (so now around US$0.063). Massive boon for us, given rising prices. With a 5kw system we feed in 1500kwh per quarter and buy back 600kwh (at ~22c), averaged across the year. Lots of variation summer to winter (sun angle) and depending on wet season, WFH, etc. On our "best" days we'll generate >38kWh. Pool runs for free year round, aircons run for free during the day. For now it's very cost effective for us without a battery. Less so with one. Less so for friends without pool / large appliance running through day. Older systems, generally much smaller, have grandfathered feed in tariffs sitting around 40c. These people tend to go out of their way not to use power during the day. Pool on at night, etc.

Interested to read other's experience.
