Choose the right system

When choosing to install solar power – also called a solar photovoltaic (PV) system – it's important to consider what size will suit your needs. For example, do you want to go carbon neutral, or do you want to add battery storage? What is your budget?

You should speak to your electricity retailer and installer because installing solar power might impact your current electricity tariff. Some energy retailers require solar customers to shift to the time-of-use tariff.

In many cases, it will be possible to install a PV system that generates as much, or more, electricity as you use in a year. Some of this electricity will be used in your home and reduce your mains electricity consumption, and some will be fed back into the electricity grid.

Other ways to improve energy efficiency and reduce your bills include installing LED downlights, improving your insulation and replacing inefficient appliances. Making your house as energy efficient as possible will reduce the size of the solar PV system you need to buy.
