How much electrical power can a 10kW solar power system generate?

Most 10kW systems will make roughly 39kWh to 41kWh of power per day, this is enough electricity for 3 average Australian homes.

How much money can a 10kW system produce?

The revenue you get from a 10kW system depends on the feed in tariff rate and the amount of power you feed in.

Most states in Australia have a feed in rate of 8c per kWh for exported power, most consumers are paying 30c per kWh for grid power, so there are 3 possibilities:

  • 1. You use 100% of the electricity generated by your solar power system, this would be a saving of about $4,499 for the first year and about $149,000 for 20 years.
  • 2. 50% of solar electricity is exported saving you about $2,690 for the first year.
  • 3. You sell 100% of your solar power saving $999 for the first year.

The way the market is trending installing a solar power system will best benefit the owner by using as much of your own power as possible and not selling any back to the grid. Large power companies want to sell fossil fuel generated electricity, thats their market model and has been for some time, they are in business for profit and not to assist you to make money and eat into their profits. In other words big coal hates solar owners.
