Anything that can help cut our electricity bill is to be welcomed, and Tesla’s solar rechargeable batteries, now available in Australia, are just the latest option. Many Australian households have already installed solar photovoltaic (PV) panels to generate their own electricity, even selling some back into the grid. Now they will have the extra option of storing any electricity they generate to use whenever they like. But the idea of becoming self-sustaining and coming off the grid altogether is not the way to go if we are to have a system that doesn’t create winners and losers.
By many accounts, the spread of solar power is unstoppable. Costs continue to fall at a blistering pace, solutions to give consumers a solar-powered home without needing to connect to the grid for back-up power are emerging, and even the U.S. Supreme Court has weighed in, with a recent ruling that is favorable for the solar energy market.
Home power storage batteries are coming to a house near you as the game-changing technology – which promises to let you store solar energy for later use when the sun isn’t shining – begins appearing across Australia’s suburbs.
When new technologies are launched, they often cost quite a lot of money, so only a few people buy them. In marketing-speak, these people are “innovators” or “early adopters”. Then as more people buy the product the cost per unit goes down, in turn encouraging even more people to buy it, in a virtuous pricing circle known as Rogers' Diffusion Curve.
