Mission Green is an Australian residential & commercial solar and battery installation company based in Melbourne.
“A quality 6.6kW solar system typically costs $4,500 to $7,000 in Australia after the federal STC discount is applied, while larger 10 to 13kW systems generally range from $7,000 to $12,000 (pricing current as at 2026). Your final price depends on the panel and inverter brands, your roof type and access, and whether any switchboard upgrades are needed.”
“Premium Tier 1 solar panels are built to last 25 to 30 years or more, and quality panels carry a 25-year performance warranty guaranteeing at least around 84.8% of their original output at year 25. Panels degrade slowly — typically about 0.5% per year — so a well-installed system keeps producing meaningful electricity well beyond its warranty period.”
“Most Australian households save between $1,800 and $3,600 per year with solar alone, and adding a battery can lift total savings to roughly $3,000 to $5,200 per year.”
“Yes. Solar panels generate electricity from daylight, not direct sunlight, so they keep producing on overcast days — typically at around 10% to 30% of their peak output depending on how heavy the cloud is.”
