Solar system costs have come down, interest rates are very low and attractive federal rebates are still available – the time to buy solar is now. Solar can pay back your investment in as little as three to seven years. After that you’ll be generating your own free electricity with high quality solar panels lasting 25 years or more.
Switching to solar power in our homes is one of the most important things we can do to reduce our emissions and do our bit for the planet. In the Sydney North suburbs approx 48% of residential emissions come from electricity use (Northern Beaches Council, Kinesis Report, June 2018).
Different homes need different sized solar systems. It’s easy to work out. On your most recent power bill look for your average daily usage in kilowatt hours (kWh). Compare your summer and winter usage to allow for seasonal variation. Then use the table to determine what size system you need.
The trend is to electrify our homes and cars. So if you think you might buy an electric vehicle or install an electric heat pump in the future, oversize your system now, rather than adding more panels and a bigger inverter later.
And if you want to reduce your emissions even more, install as much solar as your roof and budget will allow.

Batteries bring you further environmental benefits, energy autonomy and back-up during a power outage. Depending on when and how much electricity you use, batteries can make financial sense with a payback of between 7 to 10 years. Solarpro provides advice and a choice of four batteries. Two popular models are:
The best option is to pay for your solar system upfront or add it to your mortgage and take advantage of the low interest rates. You can also take out a ‘green loan’ offered by some banks, with interest rates starting from approx. 5%.
