Solar energy for individual Aussie homes is highly priced.
• A 10.24 kWh Lithium-ion battery pack with a 10 kW steady output is around AU$7,500 to AU$10,000.
• 40 No 250W panels cost around AU$8,000 to AU$12,000.
• 40 Micro panel inverters cost around AU$2,000.
All up cost (depending on labour component?) could be AU$19,500. (US$13,510)
Our annual cost for coal-fired power is approximately AU$1,700, so it'd take us around 11 years just to offset
the supply and install costs of solar—although that doesn't allow for power price variations, depreciation, varying
government subsidies, or inflation. Which means that (in very simplistic terms) that we don't get "free" electricity
until 2030. One problem is that in 10 to 15 years time, both the PV panels and the battery may need replacing.
Some PV panels here have been known to fail after only 5 years—well short of their expected (or claimed) life
expectancy.
—I'd be interested to see how these prices compare with US prices, which I'm guessing would be a lot cheaper
due to supply and demand?

I'm a creationist; I believe that man created God.
