–Key Service Insight
Optimising Efficiency & Output
Tasmania receives 1,350-1,550 kWh of solar irradiance per year. A well-designed north-facing system can achieve 10%+ efficiency above mainland averages due to cooler operating temperatures. Most residential solar systems pay back within 4-6 years.
