“If you use the solar on site, then you’re avoiding paying 25c for every kWh,” Moyse says. Power outage houston today “That value to you is five times higher to you than putting it into the grid at 5c.”

While about 150,000 homes and business will be kicked off these schemes in NSW on 1 January 2017, the party is ending for about 130,000 customers in Victoria and South Australia too.

(Others are on schemes that will continue for years to come. Electricity voltage in germany So if people are confused about their own feed-in tariffs, they should ask their retailer what’s happening with them.)

Regardless of how much people are getting hit by the changes, the principle is the same for everyone coming off a subsidised scheme – and indeed for anyone with solar or anyone planning on getting solar without a subsidised feed-in-tariff: the way to make the most of the system is to use as much of it as people can to run appliances, displacing energy people would otherwise buy from the grid.

How exactly to do that, though, can be confusing. Electricity worksheets ks1 Which appliances should be replaced? How should they be run? And are batteries a good idea?

The issue of what kind of meter to get is a minefield right now, with different issues affecting consumers depending on where they are, and options are changing rapidly.

One thing that can help anyone make the most of their solar electricity is a smart meter, says Claire O’Rourke, national director of Solar Citizens, a group that lobbies on behalf of solar customers.

A smart meter can be read remotely, and can tell when the most power is being drawn, helping maximise the benefits. Electricity and circuits They can also open up services such as time-of-use tariffs, providing savings for people who avoid using energy during periods of high demand.

Some retailers are offering discounts for smart meters in return for fixed-term contracts. Electricity vs magnetism venn diagram “It is really in the interest of consumers to shop around,” she says.

For many people right now a smart meter could be overkill. Electricity 2pm lyrics The smart meter will either be paid upfront, or in the case of free meters offered by retailers, will be paid for through increased tariffs, says Moyse. Gas law questions and answers Whether the meter will allow consumers to recoup that cost is unclear.

For people outside NSW, the lowest-cost option is to keep their current meter, at least until it’s clear a smart meter is worth it. F gas regulations Outside NSW, the current meter will work fine on the new deals.

For those customers, their meters were sending all of their solar generation into the grid. Z gas cd juarez telefono And all the electricity used was coming from out of the grid. Astrid y gaston lima menu prices So really, these consumers were not using any of their solar power directly.

So effectively, those who do not change meters will receive a small feed-in tariff for all of their solar generation, and then be buying all the electricity they use from the grid at a higher rate.

In technical terms, those customers are only doing “gross metering” but after 1 January, if they want to sell any energy back to the grid they need to be doing “net metering”.

But whether people will need a whole new meter – which could cost about $600 – or for the current meter to be rewired, depends on where in NSW they are, and who the electricity distributor is.

Moyse says rather than rushing to get a meter upgrade, it might be best to wait a few weeks or even months after 1 January, when there will be time to compare the various offers.

“It doesn’t matter even if you go a few months with your current meter,” he says. Gas under a dollar “The economic impact of that doesn’t matter too much, compared to if you change your meter early. Find a gas station near me It might cost you tens of dollars for the year.”

Jonathan Shaw says he’s very interested in getting battery storage for his house, but they’re too expensive right now. Electricity number “Once the price of batteries comes down we will think about that,” he says.

In principle it makes sense: the sun only shines during the day when many people are at work and unable to use all their solar-generated electricity. Electricity quiz 4th grade But if you can put that energy in a battery, then you can use it any time.

And the loss of generous feed-in tariffs is driving interest in battery storage, says Chris Cooper, chief executive of Suncrowd, a company using group purchasing power to get cheaper prices for batteries.

“It’s a bit of a trigger point for people to look at new technology,” Cooper says. V gas llc So far Suncrowd has run its first round in Newcastle, and had about 200 homes join together and buy batteries at discount rates.

Having a battery added to an existing solar system can significantly increase “solar self-sufficiency”, Cooper says, a measure of how much the customer relies on solar rather than electricity from the grid. Gas finder near me “With an appropriately sized battery you can boost it from 20% to about 60 or 70% self-sufficiency,” he says.

Cooper says Suncrowd is building an online tool to help people calculate their solar self-sufficiency and have been showing it to people at events they’ve been holding. Rahal e gas card “People are really motivated by seeing the numbers go up,” he says.

“Even at the bulk-buy prices that we get, the return on investment, there’s other ways you could spend your money. Gas dryer vs electric dryer calculator But there’s plenty of intrinsic value that might not be reflected in the bill savings that come with the solar self-sufficiency.”

According to a report Moyse published this month, at current prices batteries will not save most people any money. Electricity production in usa And looking at estimates of how the prices will change, they won’t save many people money until at least 2020.

If people do get batteries, the most economic type of system will be a medium or large solar system, combined with a small battery. Gas variables pogil answers “That will only supplant a small amount of your overall load, but it’s at least being fully utilised,” Moyse says. Gas x coupon 2014 Get off the gas

“If you’ve got gas, you’re generally running one of your two main loads – hot water or space heating – on gas. Gas zyklon b That’s about 70%, for most people, of your energy use. Gas tax in washington state You really need to run one or both of those on electric to be able to soak up all your solar generation.”

For water heating, very energy-efficient heaters such as heat pumps, running off solar generation during the day can be very effective. Electricity youtube In NSW and South Australia, depending on the size of the solar system, water should be able to be heated on solar generation.

When it comes to space heating, there are a number of options. Gas outage A house can be preheated while the sun is out, so less power is needed to heat it at night. Gas in oil briggs and stratton engine Or there are heat banks which use the solar generation during the day to heat clay, concrete or ceramic, and then release it at night. Gas near me Efficiency, time and shopping around

Running as many appliances during the day when the sun is shining will help use as little from the grid as possible and help use up as much solar generation as possible. Electricity receiver Most new appliances have timers on them that will allow them to run when nobody is home.

Since the appliances will still be running things at night – lights, the fridge etc – when there’s no solar generation coming from the roof, it will help to buy energy-efficient appliances when it is time to replace them.

He will get a net meter but, other than that, he’s going to continue as usual. Que gases componen el aire “We’ve done our best to have a low-consumption house anyway and we’re not going to be doing anything much different.”
