Two major energy providers have floated the idea of charging NSW and ACT households more to feed solar power into the grid during the day.
The new feed-in tariffs would affect households during the sunniest part of the day, under proposals from Evoenergy and Essential Energy to the Australian Energy Regulator.
The proposed charges were called a "sun tax" on Friday by a community solar panel lobby group, who said the charges would lead to higher energy costs for households and businesses.
