Sunny future for solar power storage - home battery system

Advances in battery technology will improve the sustainability and reliability of solar energy in Australia.
Solar energy provides energy during the day, but when the sun goes down, the grid meets the demand for electricity, and most of the electricity in the grid comes from fossil fuels.
Tesla has built tens of thousands of battery packs for its electric vehicle market and is now producing batteries that can store solar energy, which will greatly reduce the cost of purchasing batteries for buildings of this size.
Heath Walker, from Tesla, Australia, said Powerwall is a home battery that can be charged through solar panels and powered at night.
"With solar energy, people have been doing feed for so long --
In terms of tariffs, but now there is feed
In the process of lowering tariffs, people have the opportunity to control the energy in their homes through battery storage and Powerwall, which we think is the best way, "he said.
Tesla claims it will be more affordable and easier to use than existing batteries.
Andrew Reddaway, from the Association for alternative technologies, said it was a big step forward in the solar market.
"It sets a new price benchmark because the battery is very expensive and the battery will become more affordable as competitors lower their prices to reach that benchmark," he said . ".
Australian climate committee chairman Tim frankry said Australia is expected to install more than 50,000 battery storage systems each year in the next 10 years, and he believes Powerwall will change the rules of the game.
"It is expected that this will have a huge impact as you suddenly reach the point where you no longer need a coal-fired power plant," he said . ".
"The old view is that power plants provide basic loads, so we need them because they produce 24/7, but so do solar photovoltaic cell systems.
Tom Nockolds of the community authority has been working with remote indigenous communities in central New South Wales.
He said progress in battery technology will benefit these communities.
"What these communities say is important to them, not only energy affordability, but autonomy, independence and self-control, so they think battery is a very interesting technology," he said.
John Harvey's Melbourne residence in the suburbs of Glen Waverley has been closed for a year.
He spent $60,000 on his house.
A key part of this equation is the availability of reliable batteries to store solar energy.
"Even on cloudy days, you will get part [
Ultraviolet rays
So electricity is usually not a problem during the day, but it is critical to have some sort of battery backup on a night without the sun, "he said.
It is hoped that improvements in battery technology will reduce Australia's dependence on carbon fuels and make energy demand more sustainable.
