At $1.50pd or higher the option of off grid must be attractive for many customers with $540pa of savings on top of generation benefits.
Standard supply charges here SE Qld are AGL $1.09 per day and Origin $1.24 Both gst included to the nearest cent. (Per actual billing)
AGL usage peak rate is 28c near enough per kWh and Origin 27c.
Both typically show all rates and hence costs on the bills excluding gst. The split up sub-totals don’t look that big. Gst is a one line add in at the bottom of the bill.
It has been interesting listening to how each sales rep explains payback. The assumption is the money you outlay to purchase a PV system is free money and there are no CPI or inflation effects. Near enough if you are talking 2 to 3 years. Not so reliable if the period is five years or longer.
All are spruking as big a system as the roof and your retailer will permit. The pitch is the pay back benefit due to the recent jump in feed in tariff makes your electricity bill zero. For them of course is a $7,000 sale instead of a $3,000 sale. For our usage we would export 85% or more of our PV generation.
Curiously they would rather sell a $5,000+ Solar PV system than a $13,000 solar + battery system. Are they genuinely looking after the consumers best interests?
