We recently installed a Solar and Battery system in Lesmurdie for our customer, Ron. The 10.66kW of QCells solar panels were installed with Tigo Power Optimisers to minimise losses from partial shading. A 5kW Sungrow hybrid inverter was chosen along with a 16kWh Sungrow battery.
To remain eligible for the Synergy Distributed Energy Buyback Scheme (DEBS), the inverter size could not be greater than 5kW. Ron was hoping for a 10+kW system, but was reluctant to forfeit the solar feed-in tariff. Fortunately, no compromise was needed.
When connected to a DC-Coupled battery, the 5kW Sungrow hybrid inverter can output up to 5kW AC power to the home + 6.6kW DC power to charge the battery. This AC + DC power output can occur simultaneously, which allows up to 12kW of solar panels to be installed.
With shading factored in, we estimate this Solar & Battery installation in Lesmurdie will produce an average of 35 kWh per day and reduce Ron’s electricity bills significantly!

12-month savings update
Today we checked in on Ron’s system to see if our estimates were accurate…
Over the past year the system has generated 12,650kWh of solar energy, which equates to an average generation of 34.6kWh per day.
More importantly, that solar energy has been put to good use, reducing Ron’s electricity bills by more than 80% and delivering $2,640 in savings so far.

Frequently Asked Questions
How much electricity will a solar and battery system like Ron’s actually produce?
Ron’s 10.66kW system with a 16kWh battery produced 12,650kWh of solar energy over the past year, which works out to an average of 34.6kWh per day. This is very close to the estimate of 35kWh per day that was predicted before installation.
Can I get both solar panels and a battery if I want to keep the feed-in tariff?
Yes. To stay eligible for the Synergy Distributed Energy Buyback Scheme, your inverter needs to be 5kW or smaller. A 5kW Sungrow hybrid inverter connected to a DC-coupled battery can output 5kW AC power to your home while simultaneously charging the battery with 6.6kW DC power, which allows you to install up to 12kW of solar panels.
How much money did Ron save with his system?
Ron’s system delivered 2,640 dollars in savings after one year and reduced his electricity bills by more than 80 percent. The price range for a similar system is 27,500 to 30,000 dollars, with estimated annual savings between 2,000 and 4,000 dollars.
What are Tigo Power Optimisers and why would I need them?
Tigo Power Optimisers were installed on Ron’s QCells solar panels to minimise losses from partial shading. This helps the system perform better if some of your panels are shaded by trees, buildings, or other obstacles.
