Hi, Just wondering what's the difference between these different tariffs offered?https://www.agl.com.au/campaigns/solarsavershttps://www.agl.com.au/get-connected/electricity-gas-plans#/v2I'm currently getting 11.3c/kWh for my tariff, just wondering if I can upgrade to the higher tariff? Are there any requirements for the solar saver plan? Thanks!
