Big victory out of the patent office today: EFF busts the so-called "podcasting patent."  
San Francisco - The U.S. Patent and Trademark Office (USPTO) invalided key claims in the so-called “podcasting patent” today after a petition for review from the Electronic Frontier Foundation (EFF)—a decision that significantly curtails the ability of a patent troll to threaten podcasters big and small.

I'd say the answer is yes.

In 8 months I've burnt nearly 7MWh of electricity and I'm a net producer.
At current rates (36c/kWh) that's $310/month in supply cost (i.e. roughly $3800/year). Actually, 100% green power grid surcharges doubled in February, so  retail cost is now closer to 38c/kWh, but let's ignore that right now as it only makes the numbers look better.

I've designed for 10 year life on the batteries, so at the current electricity burn rate, I'll consume roughly 100MWh over the 10 year life span of the batteries. Assume I replace everything at the end of the life of the batteries - that's $30000 for 10 years of electricity supply. That means the worst case cost of that electricity over the ten year period is 30c/kWh.

Now, this doesn't consider I'll also export 20MWh to the grid over the ten year period. Nor does it factor in not needing to replace everything in 10 years time (e.g. panels have a 25 year life). e.g. if we only consider the battery+charger/inverter replacement cost over 10 years then the
cost of electricity drops to 20c/kWh for the 10 year period....

Yup, grid-backed solar hybrid is already cheaper than grid supply for large households, and for people like me it is much cheaper....
Battery storage is already economic in some parts of the grid. That may also be the case for household and business consumers in Australia's towns and cities.
