How does the Sun produce electricity?
What does PV stand for?
What is the lifespan of a Solar Power system?
Assuming typical system outputs (based on Clean Energy Council guidelines), and expected warranted lifespans, systems in Australia will pay for themselves along with a healthy return on investment.
How much electricity will my system generate?
Australian Cities Average Solar PV Output in Kilowatt Hours
System performance is highly variable dependent on many factors such as time of day, season, shading, panel efficiency, inverter efficiency, installation location etc. These figures are estimations based on average derating factors and efficiency levels.
Micro-inverter systems are on average 12% more efficient than conventional centralized inverter systems. The United States NREL (National Renewable Energy Laboratory), recently developed a repeatable method of testing micro-inverter PV systems as opposed to conventional systems in dealing with shading. For this reason, we would expect outputs of such systems to reflect these findings. The full report can be found here
