People got conned into getting solar and now they will be charged by the power companies to store it ! Enjoy ! pic.twitter.com/5xgRy4ebwf

Solar panel owners in Australia are facing a bitter pill: their eco-friendly investment might soon cost them more than they bargained for. Electricity companies, particularly in New South Wales, are rolling out new tariffs that slap charges on households exporting surplus solar power to the grid during peak daylight hours. This move, dubbed a “sun tax” by critics, has sparked outrage among green-energy adopters who feel betrayed after being incentivized to go solar for years. The Australian Energy Regulator (AER) and companies like Ausgrid argue it’s about grid stability, but the policy smells like a cash grab to many. Let’s unpack the details, the numbers, and why this feels like a bait-and-switch for Aussies who thought they were doing the right thing.
The mechanics of this new tariff are straightforward but sting. Ausgrid, which serves about 280,000 solar-equipped households in New South Wales, is introducing a two-way tariff system starting July 2025. If you export power to the grid between 10 a.m. and 3 p.m., you’ll pay 1.2 cents per kilowatt-hour after a free threshold of roughly 6.8 kWh, which varies seasonally. On the flip side, exporting during peak demand hours from 4 p.m. to 9 p.m. earns you 2.3 cents per kWh. The AER claims this incentivizes exporting when the grid needs power most, easing daytime overloads. With 952,000 NSW households sporting rooftop solar by late 2023, and only 70,299 paired with batteries, most solar owners are vulnerable to these charges unless they shell out upwards of $9,000 for storage. This setup feels like penalizing people for not being rich enough to afford batteries, especially when government rebates for solar pushed adoption without warning of future costs.
Why the change? The grid, built for one-way power flow from coal plants to homes, is buckling under the solar boom. Australia boasts the world’s highest rooftop solar penetration, with 4 million households, about 20% of the total, generating their own power, up from just 0.2% in 2007. Midday exports create “traffic jams,” risking blackouts, as seen in South Australia where operators have remotely shut off solar systems to stabilize the network. The AER and Ausgrid say two-way tariffs spread the cost of grid upgrades fairly, noting that non-solar households, including renters, currently subsidize infrastructure fixes through higher bills. Welfare groups like the Australian Council of Social Service back this, arguing it’s unjust for the 80% without panels to foot the bill. But fairness cuts both ways, why should early adopters, who invested thousands based on government promises, be hit with retroactive fees? It’s like taxing hybrid car owners for reducing emissions.
We have to get our one percent of global emissions down, no matter what it costs us in reduced living standards and power outages.
It doesn't matter that The USA has called bullshit on climate change and has left The Paris accord and has abandoned its net zero emissions target… pic.twitter.com/qD5g7YCAD4— True Science PEng, DFP, ADFS, MA, MBA. (@socratesccost) May 14, 2025
