The battery will automatically continue to power some key circuits in your home. Typically those circuits will include your kitchen and lounge so that you have lighting and can use low energy use appliances like your fridge, computers, router and TV.

Tips & Tricks

Roof insulation can save you money on your home heating costs


Good quality insulation helps keep your home warm in winter and cool in summer, making it easier and cheaper to heat properly. Start with the ceiling, followed by underfloor and walls. Without doing major structural renovations for thermal efficiency, installing thermal-backed curtains is possibly one of the best ways to save energy in the winter time. It also pays to use draft seal around windows and doors to stop cold air getting in and warm air escaping.
Control when your hot water is heated with our solarZero apps

Water heating

Hot water heating accounts for around a third of your energy use and costs the average household about $650 a year. You may be using more energy than you need to heat your water. It is important that the cylinder’s thermostat is set correctly. It should be 60°C at the cylinder (to prevent the growth of legionella bacteria) and a maximum of 55°C at the tap so you don't get burnt (children are particularly vulnerable). An extra 10°C on the thermostat could be costing you another $25 per year with a modern cylinder, or twice that with an older one.
Drying clothes outside is one way to reduce moisture inside your home.

Reduce moisture

It's much harder to heat damp air, so get rid of moisture in your home, especially when you're cooking and washing. Drying your clothes outside is a good way to save money on power. Install extractor fans in your kitchen and bathroom and open windows to improve ventilation.
Quality appliances are more energy efficient, saving you money in the long run.

Replace old whiteware

Buy appliances based on their quality, features and energy rating - the more stars on the label, the more energy efficient the appliance is - and annual energy consumption (kWh per year). It also helps to read user feedback on features and quality. Modern fridges and freezers are much more energy efficient than models made 10 years ago. A modern family fridge/freezer with a 3½ star Energy Star rating label costs around $100 per year to run. A 10-year-old fridge, of the same size, could cost twice as much. Normally, it is recommended you use the cold water setting on washing machines to save energy. However, if your hot water cylinder is powered by solar, you've got the advantage of being able to use heated water for washing during the daytime without extra cost. So, look out for washing machines and dishwashers that can take a hot water input of up to 60 deg C. Inductive hobs in the kitchen may also be worth investigating.
