How much can I save on a 13kw Solar Power System?

The amount of cash you make from a 13.3kW system will depend on how much you get paid for exported electricity (solar feed in tariffs) and how much you self consume.

Feed in tariffs in Australia pay anywhere from 6c to 20c, depending on the retailer. Let’s work on 7c per kWh for exported electricity. Most people pay about 30c per kWh to buy electricity from the grid. So let’s consider 3 scenarios to see how the payback works:

1) Use all the solar electricity in your (huge) home or business: You would save approximately $5460 in the first year. And about $150000 over 20 years assuming electricity price rises of 5% per year.
2) Export half the electricity: You would save about $3000 in the first year.
3) Export all the electricity: You would save about $1000 in the first year.
To conclude, it is evident from the above explanation: The more solar energy you self consume, the faster your payback.

How long before a 13.3kW solar power system pays for itself?

If you are using all the electricity on-site then 13.3kW will have paid for itself in under 3-4 years, assuming you pay 30c for your electricity from the grid and electricity prices rise at 5% per year. After that the electricity is free apart from a small maintenance cost.
