Solar photovoltaic (PV) systems (commonly referred to as solar panels) are a way of capturing sunlight and converting it into electricity.

The main financial benefit to consumers from solar PV is through avoiding paying for electricity from the grid.

When you install a solar PV system with a net meter, your home uses the electricity produced by the panels at the time the electricity is generated. Any additional electricity you generate but don't use is fed back into the main electricity grid.

In NSW, customers can connect a solar PV system of less than 10 kilowatts to the electricity grid. Over 348,000 households in NSW have installed solar PV systems.

There are a number of benefits and costs associated with installing solar PV. It's best to consider all of these costs and benefits and do as much research as you can before you make a decision about installing a solar PV system.

Benefits of installing solar PV

Aside from the environmental benefits, there are a number of financial benefits from installing a solar PV system. These include reductions in electricity bills and possible financial incentives offered by your retailer.

Overall, it is generally more financially beneficial to size your solar PV system to your needs rather than maximising it for the space available on your rooftop.

Reductions in electricity bills

Solar PV can help reduce the consumption component of your electricity bill if you install a net meter.

Net meters allow customers to consume any energy they generate at the time it is generated and then draw the remaining energy from the grid. If you generate more electricity than you need, it is exported to the grid. Some retailers may offer a payment for this energy.

This main benefit of solar is not visible on electricity bills. Bill savings do not appear as a line item on a customer's account, but as reduced electricity consumption and reduced electricity bills.

It is important to note that in many cases you are unlikely to offset your entire bill with solar generation. A number of factors will influence how much of a saving you will receive. This includes:

  • the size, quality and site of your system
  • how much electricity you use, and when you use that electricity
  • the weather
  • the incentive paid by your retailer.

Feed-in tariff rates and offers

2011/12 5.2 to 10.3 c/kWh
2012/13 7.7 to 12.9 c/kWh
2013/14 6.6 to 11.2 c/kWh
2014/15 4.9 to 9.3 c/kWh
2015/16 4.7 to 6.1 c/kWh
2016/175.5 to 7.2 c/kWh

Each year the NSW Government asks the Independent Pricing and Regulatory Tribunal (IPART) to determine a benchmark tariff range for electricity exported from small scale solar generators.

The IPART benchmark range for solar feed-in tariffs from 1 July 2016 is 5.5 cents to 7.2 cents per kilowatt hour (c/kWh). This is higher than the 2015/16 benchmark range, reflecting an increase in forecast wholesale electricity generation prices. Refer to IPART's report Review of Solar feed-in tariffs from 1 July 2016 External link for more detail on how the benchmark range was determined.

If you have a solar photovoltaic (PV) system with a net meter you can consume your system's generation at the time that generation is taking place.

The main financial benefit from a net metered solar system is from using the electricity your system generates rather than from feed-in tariffs. This is because when you use this generation you avoid the full usage charge for that energy. Any excess generation is exported to the electricity network. Some electricity retailers will credit you via a feed-in tariff for this generation.

Feed-in tariffs are a payment for generation. They are neither a rebate nor a payment for the full supply of electricity. In addition to generation, the retail price of electricity includes network and retailer costs. For this reason IPART's benchmark rates are not equal the retail price of electricity supply.

To view current feed-in tariff offers and compare energy offers available in your area, visit the Australian Energy Regulator's Energy Made Easy website External link.

When shopping around, you should consider all aspects of a retailer's offer, including:

  • usage charges
  • feed-in tariffs
  • any other terms and conditions including 'paid-on-time' discounts, late payment fees, or early exit fees.

Costs associated with solar

Installing a solar PV system may require an upfront investment. Generally, larger systems will require larger financial investments. The Commonwealth Government's Small-scale Renewable Energy Scheme can go some way to help reduce the up front cost of purchasing and installing solar panels or other small scale PV systems.

Some commercial businesses also provide customers with the option to lease solar PV systems or to purchase them on finance.

It is best to do your research and find out what you can afford before you make a decision on whether any of these options are right for you.
