how much can you really save by going solar? - home battery storage

Elon Musk has launched Tesla PowerwallYes and they will cut your electricity bill, but is the solar panel worth investing in?
Source: The price of power supply is going up, so it's time to follow the Prime Minister and install solar panels on your roof?
Malcolm Turnbull's blockbuster details-
Tariff solar units were revealed on Monday that after a week of eventful work, South Australia was cut off and new state residents were close to being forced to cut off power as high temperatures caused power consumption to soar.
According to the Australian Financial Review, Turnbull upgraded its Point Piper building's solar panels to 14 last year.
Also added the LG Chem battery pack at 14 KW hours, which could keep him from potential power outages.
While most Australians may not be able to afford an estimated $25,000 in PM system costs as electricity prices are expected to continue to rise, is it time to consider installing solar energy?
Things have changed. . .
Federal subsidies for solar panels and feed have changed.
In the tariffs offered by the US, reduce some of the money you get.
Some of these changes came into effect on January 1, and it seems that the prime minister is not the only one who wants to install solar energy before these changes take effect.
Warwick Johnston, managing director of solar industry market analyst Sunwiz, said the number of solar installed in December hit a record high, more than any month in the previous four years.
While the change in January 1 may be a factor, it has reduced government subsidies by only about 150, equivalent to about US dollars in system costs.
Johnston believes that the rise in electricity prices is more of a driving factor. “(Rising prices)
"I 've tampered with it in recent years, but now it's rising, especially in Queensland and Western Australia," he told the news . ". com. au.
He said the Western Australian solar installation company set the best year ever in 2016.

Johnston says the price of solar panels has fallen by about ten per cent compared to last year. The cost of the system for a standard home of about 5 KW of the 20 panels will exceed $5000.
If you want to increase battery storage, it will be twice or even three times the price of the system.
Compared to the stylish Tesla Powerwall 2, the storage price for entry-level devices starts at $2000.
This will set you back $11,000.
Powerwall 2, Mr. Johnston said.
The 0 of the 14 KW mAh battery is large enough to meet the typical consumption of 16 KW mAh per day in Australia.
"Even if it's cloudy, it can last you almost all day," he said . ".
How fast will it pay off?
According to potential electricity savings, the time required for the system to self-pay is called the return period.
This can vary depending on which state you live in, how expensive electricity is and what system you get.
There may be a big change in the price, Mr. Johnston said, depending on whether you have also decided to install a battery to store power for later use.
This is because the price of installing solar panels can be twice or even three times the original price.
"There is no storage, and the return usually takes about five years," he said . ". “A five-
The annual return of a system that can last for about 25 years is a significant return on your investment.
"But if you have battery storage installed, this may extend the payback period to about 10 years depending on the state you are in.
Mr. Johnston said that even if it takes longer to pay off the debt, installing the battery can power you during a power outage.
"You are unlikely to leave --grid . . .
But your dependence on the grid will be much smaller . "
The place you live in has a different system and for people who live in Adelaide it will pay off faster because the electricity there is very expensive and it also has excellent solar radiation.
Solar Choice, a rooftop Solar comparison and brokerage service, said it is important that people choose a Solar system that suits their home size, so they use at least half of the energy it generates directly.
If this is done, it finds that returns in most cities may take less than seven years.
For people living in Adelaide, Brisbane, Perth and Sydney, they usually spend less than five years paying for the solar system.

The exact amount you save will depend on how much electricity you use, when you use electricity during the day, how big your solar system is, whether your house is shaded or sunny, what direction is the roof facing, whether you have a battery installed or not, you have also installed smart software to maximize the savings.
To give you an idea of the savings, Nick Fitzner, the first Australian resident to install the Tesla Powerwall battery, told the news. com.
His bill fell from $660 to $50 in the same period last year.
So, what's in the hardprint?
Unless you have a battery, the solar panel can only provide power when the sun is shining, so if you are at home and use the appliance frequently during the day, you will get more from the panel.
If you are working all day, then you will not save that much money because you will not use that much electricity during the day, in order to meet your energy needs, you still need access to the grid at night.
Some people use washing machines or other appliances during the day to maximize the use of solar energy, but in order to make the most of this system, it is a good idea to also run water heating or space heating and cooling during the day.
The Association of Alternative technologies found it important to stay away from gas
If the family wants to get the most cost-effective hot water from solar energy, in its report analyzing the impact of feed changes --
Tariffs on new states, Victoria and South Australia.
"Since space heating and hot water usually account for half to 70 of the energy needs of household stationery, the report says:" If solar PV is not used to power one of these two main loads, it is difficult to maximize the use of solar photovoltaic. ".
The report was commissioned by the general environmental center and imitated the retro economic model.
Installing the battery storage on the existing solar photovoltaic system is not cost-effective, but it was found to be at least before 2020.
Smaller batteries have the opportunity to be fully utilized during the year, and larger batteries are more likely to be more cost-effective.
Nick Pfitzner and his family from Kellyville Ridge cut their electricity bill by an astonishing 90 after installing Australia's first Tesla Powerwall at home.
Source: News Australia added additional features, and if you really want to squeeze the last drop out of your system, some companies offer additional features like smart power monitoring.
Companies like Evergen, carbonTRACK, Redback Technologies, Sonnen, and posit Power analyze how much electricity a family usually needs, and use weather forecasts to decide when to get from the grid and when to use solar or battery.
Evergen claims to be able to save homeowners nearly $2000 on annual electricity bills.
Reposit works the same way, but also buys power stored in batteries during peak periods from homeowners and feeds it back to the grid.
Clint Luna, a Queensland resident, said he paid about $18,000 for his Reposit system, which also included $6.
Solar panels, inverters and Tesla Powerwall at 5 KW hours.
"I used more electricity because I had an electric car and a fairly large house, but I think what I saved was $2500 to $3000 a year (in power bills)
Mr. Luna told the news. com. au.
He says he thinks the system is valuable, especially since they now offer Tesla Powerwall 2.
0, the cost is roughly the same as the first version, but the capacity has doubled.

Source: There are a lot of factors to consider how suppliers get the best deal, which is why Mr Johnston suggested going to an approved solar retailer.
They will be able to estimate the return period more accurately, as they will also be able to understand the electricity usage patterns of the home and whether the roof is heading in the right direction.
Mr. Johnston encouraged people to use the retailers recommended by the Clean Energy Commission of the solar company's peak agency.
"They will provide a fiveyear whole-of-
"System warranty, but some others may not," he said . ".
"It is difficult for consumers to distinguish between panel brands (versus)panel brand B.
The salesperson will also claim the best, which is why it is better to go to the retailer you trust.
"If you get the battery, it is also important to check the warranty period of the battery, because some systems can pay off before the warranty period is full.
"We recommend that shoppers who are interested in batteries now choose smaller battery banks because smaller systems spend less capital and return faster (as)
They are more likely to be fully utilized than larger systems, "said a solar energy spokesman.
