Understanding Diamond Energy's feed-in tariff
FIT isn't everything
A high feed-in tariff looks good, but your usage rate and daily supply charge often have a bigger impact on your total bill. A plan with a lower FIT but cheaper usage rates can save you more overall.
Single vs time-of-use
Single-rate FITs pay the same amount regardless of when you export. Time-of-use FITs pay more during peak periods but less during off-peak, which is when most solar exports happen.
Self-consumption value
With Diamond Energy's FIT at 3.1c and usage rates around 41c, every kWh you use yourself instead of exporting saves you an extra 37.9c.
Is Diamond Energy's 3.1c FiT worth it?
Diamond Energy's best rate of 3.1c/kWh is below their average usage rate of 41c/kWh. Every kWh you self-consume instead of export saves you an extra 37.9c.
A battery lets you store your daytime solar for evening use, so more of every kWh you generate stays with you.
Federal battery rebate: about $3,610 on a 14 kWh battery. One Why Solar Approved installer, one free written quote, and fifteen minutes with a solar expert before you sign.
