Solar offers

Putting in a solar energy system can cost a lot of money. But some people might end up saving money, depending on:

  • how they use energy 
  • what offer they sign up to, and 
  • how much they had to pay to put in the solar energy system.

You can compare electricity offers available to customers with solar energy systems on the Energy Made Easy site.

How does solar work?

Solar energy systems use solar panels. Solar panels can also be called photovoltaic (PV) panels. The panels usually last for about 20 years. They turn the sun’s energy into electricity.

Solar systems can be:

  • connected to the electricity network—this is called the grid, or
  • separate from the electricity network—this is called off-grid.

When you put in a solar energy system that is connected to the grid, you might get paid for the electricity you put back into it.

How do you get paid for putting electricity back into the grid?

This depends on:

  • government rules, and
  • whether your retailer has its own solar feed-in tariff.

A solar feed-in tariff is an amount that you get back for putting solar energy into the grid.

The amount of money you get depends on:

  • the type of solar system you have
  • the amount your state or territory government has set, and
  • whether the retailer adds more to what the government has set.

There are two kinds of solar feed-in tariffs:

  • net feed-in, and
  • gross feed-in.

Net feed-in tariff

This is where you get credited for the amount of electricity over what you use.

Net feed-in tariffs are used in:

  • Victoria
  • South Australia
  • Tasmania, and 
  • Queensland.

Gross feed-in tariff

This is where your retailer:

  • credits you for all the electricity your solar system feeds into the grid, and then 
  • charges you separately for all the electricity you use.

Gross feed-in tariffs are used in:

  • the Australian Capital Territory, and 
  • the Northern Territory.

Retailers in NSW can choose which type of feed-in tariff to offer, so net and gross are both used.

Will I save money with solar?

Going solar doesn’t guarantee cheaper electricity bills.

There are things to think about, like:

  • the size of the solar system 
  • how much sun it gets
  • how much electricity you use and when
  • the energy offer you sign up for, and
  • whether you have to pay for a new meter.

Some people might choose to go with a solar panel supplier to purchase a solar system. There are some extra things they need to think about, like:

  • How the price of electricity is worked out—for example, is it fixed or can it go up?
  • Who looks after the solar system—for example, maintenance and repairs.
  • What happens at the end of the offer or if you move—for example, who will own the system?

The Clean Energy Council’s consumer guide to buying household solar panels can help you decide if solar is a good choice for you.

It has:

  • questions you should ask installers and retailers, and 
  • a step-by-step guide to putting in a solar system.

Solar hot water

Water heating is the largest single source of greenhouse gas emissions from the average Australian home. It makes up about 25 per cent of household emissions.

 

Putting in a solar hot water system is different to putting in solar panels. You don’t need to sign a solar offer with a retailer when you put in a solar hot water system.

GreenPower

GreenPower is a government program that lets your energy retailer purchase renewable energy to sell to customers.

Renewable energy can come from:

  • wind 
  • sun, and 
  • rubbish waste.

When you sign up to a GreenPower offer, you can choose how much power you want from renewable energy (up to 100 per cent). Just remember that the more GreenPower you choose to get, the more it usually costs.

Look for ‘renewable energy charge’ on your bill to see how much GreenPower costs.

You can compare electricity offers with GreenPower on the Energy Made Easy site. The cost of GreenPower is in the Energy Price Fact Sheet or the retailer's written summary of the offer.

Where does your retailer buy their electricity from?

Different retailers get different amounts of renewable electricity to sell. You can ask the retailer to tell you more before you sign up to an offer.
