Can A Home Battery On A Time-Of-Use Tariff Pay For Itself Yet?

Home Battery - Time-Of-Use Electricity Tariff

If you have a home battery, a time-of-use tariff can save you money. 

How much depends on…

  • Battery Capability:  This includes usable storage capacity, power output, and flexibility.
  • Location:  Time-of-use tariffs vary greatly from state to state.  To a lesser degree, they can vary within states.
  • Electricity consumption habits and solar electricity production
  • Whether or not you are part of a VPP (Virtual Power Plant) that allows a time-of-use tariff.

South Australia solar power - electricity tariffs

SA homes are not required to have a time-of-use retail electricity tariff when getting solar

Silicon Price Hike Increases Solar Panel Production Cost By Around $34

Ninety-eight percent of the world’s solar cells are made from silicon.  This is thanks to its suitability as a PV material and its low cost compared to alternatives.  While the price of solar silicon has its ups and downs, the overall trend has been downwards.  It reached a record low in June 2020.  After taking inflation into account, it was around one-thirteenth of its 2007 price. 

But the record low didn’t last, and over the past 12 months it has gone from under $7 US per kilogram to over $28 US.  In relative terms, this has been the largest solar silicon price increase in history.    [Read more…]

New Energy Rating Labels For Air Conditioners Are Brilliant

Zoned Energy Rating Label - Australia

New aircon energy rating labels! Are you excited? You should be…

The most energy-efficient and cost-effective way to heat your home is to use your reverse-cycle air conditioner.  Even the least efficient aircon uses far less energy than electric resistance heating.  But buying the least efficient air conditioner is a bad idea.  You’ll be better off with a highly efficient one — or at least the most efficient one that doesn’t cost an arm and a leg.

How Well Does Solar Work Through Winter?

Solar panel performance in winter

Over the next week or so I’ll write some articles busting solar myths because, if I’ve learned anything from 25 years of internet use, it’s way easier to complain about something than go through the effort of doing something useful.  Today I’m tackling solar energy output in winter in Australia.

Solar power and slow cookers
