They can be depending on your needs. Lithium iron phosphate batteries are pretty cheap for their capacity. If you build your own power station with them you'd be surprised how far your money goes.
- UltraSane 11mo agoIt is much more expensive that just buying electricity from the grid at night.
- scheeseman486 11mo agoIn Australia, if you have the space for rooftop solar, it's far cheaper in the long run to buy solar+battery. We did the math for our household and even if grid prices are stable (which they aren't, they're fast increasing) we're still going to make money back on the investment in less than 4 years. Granted this includes a government rebate for the battery, but overall the prices have plummeted. Any government that isn't pushing for renewables and energy storage at this point is actively working against it's citizens.
- UltraSane 11mo agoDoes that take into account the free electricity?
- scheeseman486 11mo agoNo, and once the Solar Sharer scheme kicks in it'll be very helpful in avoiding leaning too hard on the grid in the evening after rainy or overcast days. It's a fantastic way to solve oversupply; give it to everyone, including those who have batteries in areas where the weather restricts solar output. https://www.abc.net.au/news/2025-11-03/energy-retailers-offer-free-power-three-hours-dmo/105965472 https://www.abc.net.au/news/2025-11-03/energy-retailers-offe...
- UltraSane 11mo agoThe free electricity seems ideal to charge batteries with.
- peppersghost93 11mo agoIt's worth the price if you live in an area where grid stability is not a given.
