Brett and his family have a 3.5kW solar system together with solar hot water and a battery. Discover how some changes could still help them save more on their bills.

Brett’s family have a large solar system with battery storage and solar hot water on their home in Glenhaven, NSW. Brett has been using energy monitoring for over 4 years and uses only electric appliances.
Brett was aware of how shading impacted his home when installing solar, and has tried to position panels with the goal of minimising shading in mind.
Monitoring has helped Brett track how shading impacts his system: “The data is so detailed that when I noticed a dip in our solar production at the same time everyday, I was able to pinpoint the exact tree that was causing it.”
Brett recommends monitoring individual loads to gain better insight into energy usage. By separating the monitoring of important loads, Brett has been able to find faults and act on them quickly:
Brett and his family have all the tools to monitor their energy and use effectively. The biggest suggestion Solar Anlytics had therefore is to start using timers on large appliances (washing machine, dishwasher etc.), so
these can be consistently used during solar-producing hours.
- Consider investing in ceiling fans to reduce reliance on air conditioners
- Turn off spa heating in periods where usage is low, such as winter
- Use timers to use large appliances during the day to make the most of solar when its available
The majority of Brett’s family’s electricity usage occurs during the evenings and on weekends so Solar Analytics recommended using a flat rate tariff to ensure electricity used at night isn’t charged at peak rates.
As with many other solar homes finding a high feed-in-tariff is not as important as finding a low energy usage charge and daily connection charge.
Steph and her family have a small 1.5kW solar system on their home in an inner Sydney urban area. Find out how a few small changes to their energy tariff and energy use at home could help them save more.
