The McClean family from Blackheath were spending $4,290 annually on electricity for their large property before Avery Solar & Electrical installed 26 Trina solar panels with micro inverters and a Sigenergy 10kWh battery system. Now they’re using their solar and battery to heat their home during Blackheath’s cold winters and keep cool in summer, with a positive return on investment expected between 7-8 years, transforming their energy costs whilst maintaining year-round comfort.
