Just switched my electricity plan from an agl plan from ages ago with bill credits to the solar savers plan as it worked out cheapest over a year based on my usage and solar export from the past year's data.
The solar savers has a 20c a day higher supply charge and slightly more expensive rate per kWh than the other plans offered.
This got me thinking (now a few days later) is there a reason I couldn't switch to the cheapest agl plan for just winter in say April to August when my solar puts out f all to the grid and then switch to solar savers for sept to march and do that 2x every year?
Nope, should be sweet
