Australia guide the world in domestic roof solar installations. There are solar panels in more than 4 million households. In the last 20 years, installations have become large and cheap. My solar array was only 1.9 kW and cost AU $ 6000. For very little, now you can get 3 times size. However, as the ranks have increased at the same time, the Fed in tariffs for solar energy (FIT) has been reduced. While two decades ago, 50 % was close to one kW, now you are lucky to get 8 %.

What to do with all this power in the middle of the day? The answer is home battery. Their prices have fallen, and the increasing number of solar panels + batteries has increased – but the Necessary to create more demand is not so fast.

The Australian federal government offers its cheap home batteries subsidy. 30 % off – what deal! The AU is on the offer to subsidize the installation of small-scale battery systems (5 kW-100kW WH) for $ 2.3 billion households, businesses and community organizations. Come and get!

And they ever have. In the first 3 weeks for this scheme, 11,500 applications have been received for the operation. Not surprisingly, Tesla is sending me an email every other day, promoting power wall. Sadly, I bought a house battery several years ago and paid double the price of the tech outside. The subsidy will be minimalized annually and “according to reducing battery prices, it will gradually decrease by 2030.” As it should be.

Many of the current solar array are putting batteries. According to Melbourne’s ageSmall scale battery systems are being added to the grid every 8.7 days equivalent to a large battery of South Australia. The scheme has been running for about 2 months now, with Australians applying 15 MW worth of batteries a day. One thousand batteries in one day! It is five times an average of 2024. The Australian Energy Market Operator (AEMO) predicted that it could not be achieved by 2035. Once again, the market is showing professional crystal ball geesters. Is this the second revolution in domestic electricity?

The government expects that participating households, businesses and community organizations “need to reduce electricity bills and store it by reducing more cheap and clean solar power.” Not only will Australians be able to use their homes to make electricity to their homes during fast times, but when prices are high, they can have some excessive sale in the grid. Some have been predicting a return on investment in about four years. Does this mean the end of the solar duck, or is the least lack of solar ducks? This should mean that expensive gas (methane) turbines will be very little needed at the peak of Syria.

The Director of Green Energy Markets, Truston EDIS, has made a significant point: “You do not need anything you need to do anything. At the current rate of installation, within five years, the concepts that will be installed 10,000 MW of battery capacity.

“When you think we have a coal of 20,000 MW is a huge thing [in Australia]”They say more.”[D]For batteries, malnutrition has gone to the nuts.

The Australian government is examining its emission reduction goals by 2035. The widespread use of home batteries and the implications of its grid means that these goals may be more “malicious”.

By 2035, existing state and regional operations can be expected between 66 % and 71 %, these results show that the Albanian government should make 80 % effort for a science -linked target. [reductions] By 2035, “Kelly Oen Shani, CEO of the Australian Conservation Foundation, said.

Before the cheapest battery scheme of the house, four roofs were being installed for each battery, said Warwick Johnston, Managing Director of Solar Consultancy Sunways. Now it’s one for one. Clean Energy Regulatory Data shows that most of the installations (40 %) are in New South Wales. Queensland has 20 %, South Australia 17 %, and Victoria 12 %. If they contact the Virtual Power Plant (VPP), home owners in NSW may also claim additional subsidy. What do you think about encouraging all applicants to be part of the VPP for subsidies? This will mean. It looks like it covers….

“To qualify for battery discounts, a grid battery system-which includes its inverters-should have the technical ability to participate in the VPP, which should provide users either in installation or in the future to join a VPP… any kind of need to control the battery and the site.”

Many of my Facebook friends are installing the maximum number of permitted power walls. I hope you bring your stories to future articles. Like many other people, they are also hungry for high -energy costs, and they may make the sun shining a little grass. And you will never know when the next flood will come and wash the power lines, or the next fire will burn the electric pole, or the next storm will blow up the high stress towers. It’s Australia, and we are in the middle of the climate crisis. Backup of battery never hurts.

Now, hopefully the next money will fall. If my home battery saves me money (and does not explode in flames), then it is possible that the power car will save me as much money and it will not be fire. However, this is usually the same chemistry. I am hoping that this increase in home battery installations will reduce the FUD around the power vehicles and increase the number of EVs on the road. Looking at this massive optic, I wonder if this is just the price point that is important? For many Australians, the future is now cheaper and more electrical.
