Good quality panels are designed to last for 25 years and inverters (which convert the generated power from DC to AC and have connection points for a battery) up to 15 years.

Roughly 1kW is $1000. Actual costs will depend on factors such as roof accessibility. A variety of finance plans are available. Talk to your bank, specialist providers such as Brighte, and your electricity retailer to find out your options.

A solar system will often pay for itself in 4-5 years. It depends how much of the power you generate you use at home, vs how much excess generation you export to the grid.

Unless you have roof ownership as part of your strata plan, it is more difficult but not impossible to enjoy the benefits of strata on low to mid-rise strata buildings. There are two main approaches:

1. Using a solar system to power common area lighting and services to lower outgoings costs.

2. Sharing power from a rooftop system amongst multiple units.
