Time of Use Electricity Tariff

The autumn-early winter electricity bill arrived recently. This one had an extra $109 for a "service truck" visit in June. On querying this item, it was as I suspected, a cost for the service visit when the meter changed over in January. It has taken 6 months for the distribution company to bill the retail company.
While talking to the helpful operator I queried the low solar buyback tariff and got switched to their solar division.
To my surprise, I found that there may be a way to receive Victoria's higher 60c buyback rate for my generated electricity as well as keeping the peak/off-peak rates. This is now called the Time-of-use tariff and the rates compare well with my current tariff.
So now I will try and navigate the maze of forms and possibly appeal processes to see if we can action this. It seems this change has occurred recently following confusion between distribution companies, smart-metering roll-out and possibly other factors.
So although my bill is less than at a similar time last year, showing the effect of the solar generation, the buyback increase will also affect the overall costing.
Anyone who lives in their own home, has a reasonable north-facing roof and a couple of thousand dollars spare would be well advised to go solar. The economics, with the current REC's system and increasing competition in the industry, is obvious.
So if you still have the $1800 bonus the government have given us, why not invest in your own solar generation system?
